Microsoft is to be doing further work on headphones that follow your gestures

Microsoft Research

Thinking beyond audio: Augmenting headphones for everyday digital interactions – Microsoft Research

My Comments

As part of the “Headset Wars” where headset manufacturers are putting research in to and marketing the best-value Bluetooth active-noise-cancelling headset, there is research in how to improve the headphones’ user interface.

Currently, there are some over-the-ear headphones that use touch-based gestures for basic control routines like starting or stopping multimedia, taking or ending calls and adjusting volume. As well, some active-noise-cancelling headphones recognise you cupping our had over the earpiece as a way to override ANC, amplify the outside world and pause multimedia so you can engage in conversation with someone near you.

Why

One issue that is bringing Microsoft in to the headphone innovation space is the intense competition between headphone manufacturers when it comes to high-quality Bluetooth active-noise-cancelling headphones and earbuds. These manufacturers are seeing their headsets being used at work, at home and while travelling for entertainment and personal communications.

As well, the drive towards videocalls and video conferencing during COVID and the associated work-from-home orders has had us want to see a better way to engage in that Zoom videoconference. The various goals that came about include providing each user with a sense of dignity and privacy during these calls, especially if they need to get up to use the bathroom or answer the door.

Then there is the ability to effectively “talk to” a particular individual in a multiparty video conference when you direct your gaze at that particular person in the default multi-screen view.

It is also being seen as part of augmented and virtual reality such as having an avatar mimic you. This is even a feature that is becoming part of video conferencing and allied use cases where participants see themselves as though they are in a virtual space.

What is being brought out through the research

Here, it is about using the headphones to follow your head movements or recognising when you put your headphones on or took them off.  There is also the idea of using mid-air hand gestures as a control mechanism with this being based on LiDAR technology to recognise these gestures.

The use of head gestures and hand gestures recognised by headphones is being seen as beyond call control for a videoconference. It includes allowing avatars that represent a user in a videoconference or video game  to mimic the user they represent.

It also allows for head movement to be recognised as input for videogames. This would come in to its own with games that have the first person as their primary point of view like driving games, first-person shooters or role-playing / adventure games. I would  see this also come in to its own as another input for augmented and virtual reality.

How could this be delivered

The Microsoft Research augmented headphone technology could be delivered as an head-worn attachment which may please people who use headset styles other than over-the-head headsets. Or it could be a clip-on attachment that clips to the headband of an existing over-the-head headset. Headphone manufacturers could even integrate this functionality in to their headphone products, especially if it is to be a product differentiator.

As well, a Bluetooth or USB connection would be used to transmit the head movements and had gestures to the host computing device. Here, it may be based on USB Human Interface Device specifications that relate to augmented and virtual reality use cases. If this functionality is to be delivered as an accessory for a Bluetooth headset that has a USB-C socket like just about all of the Bluetooth active-noise-cancelling headsets, there could be USB-Bluetooth forwarding. Here, the Bluetooth headset would “catch” all the head movements and gestures from the USB-connected accessory and forward them to the Bluetooth-connected host device using the one link.

But what needs to happen is for the head movements and gestures to be recognised in a standard form like a USB HID Device Class. This can allow for operating system support and avoid the need for headset manufacturers and software developers to reinvent the wheel every time they want head-movement support in their setup.

Conclusion

What Microsoft is doing is to extend recognition of head movements and gestures beyond virtual reality and augmented reality to regular computing and communications tasks using ordinary headsets.

Super Bowl 2021 ad for Logitech’s latest products

Logitech made so much money during the pandemic it could afford this Super Bowl ad – The Verge

Video

Logitech Super Bowl ad – Click or tap to play in YouTube

My Comments

In North America, the NFL Super Bowl is the penultimate final match for American “Gridiron” football. This also has the half-time entertainment with some big-time stars performing but it is also seen by the TV stations as the most valuable TV show there. It is thanks to many people watching it wherever they can on their TVs and this same football show ends up as a showcase of the best TV commercials that Americans have seen.

Most years I have highlighted and commented on consumer-technology ads that have appeared in this advertising showcase, incase you were overseas or were at a Super Bowl viewing party but missed that ad while reaching for that chicken wing or dipping those chips in that special dip. For example I had cited an ad for Microsoft’s Xbox Adaptive Controller with its focus on inclusive gaming.

This year, Logitech had joined the Super Bowl advertising showcase with an ad highlighting their current computer-peripheral product range in a creative context. Logitech is one of those brands I value due to their consistent use of Bluetooth as a wireless-connection option for all of their wireless input devices rather than just the dongle-based wireless approach. As well, the development of Darkfield technology has impressed me due to the ability to use suitably-equipped optical mice on glass surfaces.

Logitech had made so much money during 2020 thanks to the COVID-19 coronavirus plague. This is due to them selling computer peripherals like mice like the MX Anywhere 3 Bluetooth mouse I have reviewed, keyboards and Webcams for us to equip our home offices with. For example, a lot of these devices would have been used to build out a desktop workspace for that laptop as mentioned in this HomeNetworking01.info article. Some of the pundits were evens saying that Logitech could even produce and run a Super Bowl ad on the back of their profits of these sales.

The Super Bowl ad carved out a message about determination in the face of what may be perceived as logic. This may be due to Lil Nas X (Wikipedia article) and his life including coming out as gay and hitting out against homophobia in hip-hop music, or fusing country-and-western music with elements of the hip-hop style especially rapping.

The vision in the ad underscored the use of a wide range of Logitech input devices like mice, styluses and keyboards with differing computing devices for creative purposes. There wasn’t any highlighting of certain products within their latest product lineup but it was about showing the whole lineup working together.

It is showing a distinctive direction for tech-focused advertising where the technology is for use by everybody no matter who they are, along with the idea of running these campaigns during key sports events where everyone would be watching.

Building out a desktop workspace for your laptop computer

Desktop workspace with Dell XPS 13 laptop computer

The laptop-centric desktop workspace

Increasingly, a significant number of laptop-computer users set up a desktop-based workspace to use their computer at. With this arrangement, they equip the workspace with a full-sized keyboard and mouse alongside a large screen, with the computing power taking place inside the portable computer.

Why a desktop workspace for your laptop computer

The establishment of a desktop workspace for your portable computer is primarily about creating an ergonomic environment with full-sized input devices and larger screens that can stand long work sessions.

Some users may find this more important with ultraportable computers that use a smaller keyboard or omit things like numeric keypads. Similarly, you may find that a full-sized mouse may have work better for you than just relying on the computer’s trackpad.

Increasingly this arrangement appeals to the idea of running two screens thus creating a larger visual workspace. In most cases, this can be achieved through the use of a desktop monitor along with the laptop’s own display with them both set up to be a single display.

The laptop still is portable for use in the lounge during winter

Here you don’t lose the flexibility associated with using a laptop computer thanks to its portability. For example, your computing arrangements can suit the seasons at home if you have a good outdoor space that you use when it’s warm or you have a solid-fuel fire or a heater which conveys the look of a fire that you use when it’s cold. Or you can use a café or similar location as your “secondary office” when you want to work away from distraction. But you then are able to head back to your primary workspace where you want to benefit from what it offers.

Where is it relevant

A fully-equipped desktop workspace for your laptop computer is relevant to one or more areas you place a significant amount of your working time at. For a work-home laptop, this could be at your desk at the office you work at as well as your home office if you maintain this space. It will also have a strong appeal to those of us who run small businesses or community organisations with a physical shopfront but do a significant amount of the “homework” associated with running the organisation at home.

It also appeals to the “hot-desk” concept where different users end up using the same workspace but want to bring their computer, therefore their data, to that workspace. This is a significant trend that is being encouraged in new-style workplaces who are moving towards practices like telecommuting. But it also appeals to situations where, for example, members of your family want to use a fully-equipped workspace to do a significant project.

Secondary workspaces

Similarly you can create multiple desktop workspaces with this kind of setup at different locations. I mentioned this earlier in the context of a “work-home” laptop taken between your workplace / business premises and your home.

But this can also extend to a secondary residence like a holiday or seasonal home, whereupon you can establish a similar desktop workspace to use with your laptop computer at that location. Or this could be about a similar workspace set up in a study for your older children to use while completing their assignments and projects on their laptops.

Here, you may end up “pushing down” older equipment that has mileage left in it to this secondary workspace as you buy newer better equipment for your primary workspace. Examples of this would be to upgrade to a more capable USB-C or Thunderbolt 3 dock or a better monitor while your existing USB-C dock or monitor ends up at the secondary residence.

The equipment

Most of the equipment will be similar to what you would equip a standard desktop computer with but you may have to be particular about the connectivity issue concerning your laptop computer.

Input devices

Full size mice can earn their keep here at your primary workspace

You will need to equip your desktop workspace with a full-sized keyboard and a full-sized mouse or other input device. Here, make sure you choose the keyboard or input device you are comfortable with. Be aware that if you find that the travel-sized mouse can suit your needs equally for continual use as a full-size mouse, so be it.

These can be either wired or wireless with the former requiring a USB Type-A port on the computer for each wired device. Or the latter can be wireless, either using a transceiver dongle that plugs in to the computer’s USB Type-A port or Bluetooth which uses the laptop’s Bluetooth interface.

Some of the wireless “desktop sets” which consist of a keyboard and mouse in one package may allow one transceiver dongle to work with both the keyboard and mouse. But with Bluetooth you don’t need to deal with transceiver dongles because you are using the computer’s Bluetooth interface.

Screens

LG’s 32″ 4K monitor with HDR10 – larger monitors like these are relevant for the desktop workspace

If you have a 2-in-1, especially of the convertible type, you may find that having it set up in the “viewer” or “tent” mode will allow you to have a screen without its keyboard or trackpad being active. You may have to make sure Windows 10 is operating in “desktop” mode if you are using the external keyboard and input device.

As well, a good-quality display monitor with the screen size you are comfortable with and resolution that suits your needs can work well as your main or secondary display. The secondary display can come in to its own by providing an increased screen size and you may find that you have to use a laptop stand or bracket that suits your computer in order to prop your computer up to screen level.

If the monitor has its own speakers and connects to the setup via HDMI or DisplayPort including USB-C DisplayPort alt, you will need to have the default sound device being the laptop’s graphics-infrastructure display-audio device. Preferably in this case, the monitor should have an external audio output if you want to use headphones or a better sound setup with it.

Dell Inspiron 13 7000 2-in-1 Intel 8th Generation CPU - presentation mode

Having a 2-in-1 like this Dell Inspiron set up in viewer mode like this and using it with a keyboard and mouse may be a starting point for an enhanced workspace

Most operating systems will have the ability to have the screens work as either a copy of each other or as though they are one large display. It is in addition to setting up your computer to only use the external monitor as its display rather than its internal one. In this case, you may want to have the screens work as one large display if you value the increased desktop real estate or simply use your large monitor as your working display at your main workspace.

You can even go about having both screens as one large display but use the laptop’s built-in screen to “park aside” windows that you aren’t working with while  you have the larger screen for what you are currently focusing on. That would be effective for those of us who use a 12”-14″ ultraportable as part of this setup.

Sound

Creative Labs Stage Air desktop soundbar speaker

This Creative Labs Stage Air soundbar and similar desktop speakers could provide the sound for your desktop workspace

This can be satisfied through the use of desktop speakers, including a desktop soundbar like what Creative Labs offers. Or that old amplifier or receiver connected to a pair of bookshelf speakers can do the trick. In the same way, that 1980s-era “ghetto blaster” that has a selectable line input can answer the same need.

The speakers or amplifier can be connected to your laptop’s or monitor’s headphone or line-out jack or you may want to use an outboard sound module for this purpose. You may find that that the dock you use to provide one-cable connectivity to your laptop will have a built-in sound module that has very similar functionality to a USB sound module.

But the standalone sound modules are more likely to have better audio connectivity or audio reproduction electronics. Here, this may be of benefit for those of you who have a  home-office “den” that is equipped with high-quality audio equipment or you are using turntables or tape decks to salvage legacy media to digital form.

Such a setup may work well if you want better sound at your primary workspace and don’t want to rely on the laptop’s tinny built-in loudspeakers there. This would be important if you listen to music, watch videos or play games using that workspace.

Storage

USB portable hard disk

These portable USB hard disks are seen as a way to expand storage capacity for your workspace

You can also get by with using a USB hard disk or solid-state-storage device not just as a data-backup device but to offload data that you won’t be needing to keep on your laptop’s own storage subsystem. This will be of importance with those computers that use a small SSD as their onboard storage.  On the other hand, a network-attached storage could serve the same purpose as a data-backup or offload storage device. This is more important if you want to keep multimedia data available to your home network.

If you deal with optical disks like DVDs or Blu-Rays, you may find that a USB optical drive compatible with the disks you deal with may work well for this setup. This is more so if you are using the disks primarily at your desk, perhaps primarily to archive data; or simply want to play CDs, DVDs or Blu-Rays through your computer including ripping them to the computer’s storage subsystem. The same goes for other legacy removeable media like floppy disks or ZIP disks whereupon you use USB-connected drives for gaining access to data stored there.

Pioneer USB Blu-Ray optical drive

A USB optical drive can come in handy here if you use CDs, DVDs or similar discs at all.

Some of you may find that keeping a highly-portable USB hard-disk / SSD and/or optical drive may answer your needs if you are intending to use them on the road. This may be about moving photos you take with your camera off your laptop or watching a DVD or Blu-Ray during the long-haul flight. In the case of secondary residences or similar premises, you may prefer to take the highly-portable USB storage device with you when you leave so your backup or offload data stored there is safe with you.

Network connectivity

You may find that if you have an Ethernet connection near your workspace, you may want to connect your laptop to the network and Internet via Ethernet rather than Wi-Fi wireless. In most cases, this will allow high-throughput low-latency network and Internet connection and you may come across this if you have located your router in that workspace, wired your home for Ethernet or your business has wired Ethernet infrastructure.

This situation is answered through the use of a USB-based Ethernet network adaptor that plugs in to your computer’s Ethernet ports. But a lot of well-bred USB-C and Thunderbolt 3 docks have this function built in to them. Let’s not forget that you may find that your laptop has its own Ethernet port especially if it is a mainstream business or gaming unit.

Connecting many devices

The question that will come up frequently is how do I connect the many devices to my computer especially if it has fewer ports. Usually this would be about connecting and disconnecting many cables as you bring your computer to this workspace

Hubs and docks

To simplify this process, you may find that a USB hub or dock (expansion module) may come in to its own here.

Belkin USB hub

A typical USB hub

A hub will have a number of USB ports for use with USB peripherals while a dock will have a range of different connections and interface circuitry for different devices. You may find that your monitor may have some of this functionality built in to it and this can be a real boon because you don’t have to deal with a separate box. It will be more so if you are dealing with a USB-C monitor.

Here, you connect all of your peripherals that would be normally connected to your computer to this device. Then you have a cable that connects the hub or dock to your computer to expose all those peripherals to it and its operating system. Previously these used a USB 3 Type-A connector but most of them now use a USB Type-C or Thunderbolt 3 connector due to the high data throughput and, in some cases, power-supply functionality that they offer.

Dell WD19TB Thunderbolt dock

A USB-C or Thunderbolt 3 dock like this Dell WD19TB dock is relevant for this kind of workspace

If your computer supports USB Type C or Thunderbolt 3 connectivity, these devices come in to their own with a DisplayPort “pass-through” monitor connection. In a significant number of cases, you will find that the hub or dock comes with a power supply and works to USB Power Delivery specifications. This will mean that you will be able to keep your laptop’s power supply in your laptop bag rather than always bringing it out when you want to work at home. With the power capacity, I would look for something that is at least 45 watts in order to cover most computers’ needs.

On the other hand, if your computer doesn’t have a USB Type-C or Thunderbolt 3 connection, you will have to connect your external monitor directly to the computer’s display socket. Some of the USB 3.0 docks will have a display connection of some sort and this will be facilitated through the DisplayLink standard which “pipes” the video output from your computer’s graphics infrastructure via the USB 3.0 output to the display connection. This setup may appeal for a secondary-display application where display latency isn’t an issue.

The rule with these devices is to make sure you are purchasing one that suits your current needs. As well, if you do choose to upgrade an existing hub or dock  you can “push” your existing hub or dock in to service for another workspace that you use less regularly. Or if the hub or dock is small and light enough, it could be something you could stuff in your laptop bag to connect up other peripherals when on the road.

Accessories

Some of you may use a laptop stand or bracket as part of your desktop workspace. Here, your computer will either clip in to the bracket or rest on this stand, typically to have the laptop’s display at the same height as your main computer monitor.

Here, make sure that the laptop stand or bracket is sturdy and can continue to do its job for a long time. It is also worth making sure that the stand is adjustable so that the top of the computer’s screen is at the same height as the top of the monitor’s screen.

Moving from desktop to laptop?

Some of you may be building out that desktop workspace for your laptop computer as part of moving from desktop to laptop computing.

Here, you can retain most, if not all of your desktop computer’s peripherals and connect them to your new laptop computer, whether directly or via a hub or dock. As well, an independent computer store or electronics store may offer self-powered USB disk-drive enclosures that fit most standard-sized internal-mount hard disks or optical drives used in desktop computers. This will mean that you can move hard drives, SSDs or optical drives out of you desktop computer’s case to these enclosures so you can continue using them, something that can be done with a screwdriver.

Lenovo even had this idea in mind with their BoostStation external graphics module which connects to the host computer via Thunderbolt 3. Here, this unit didn’t just have room for a graphics card but also had the ability for you to install a hard disk or SSD like the one you have removed from your old desktop computer.

Similarly, you will have to remove the hard disks or solid-state storage device that are in your desktop computer from that computer before you send it off for e-waste recycling. This is to preserve your privacy and the confidentiality of your data. Again, if you needed to, that computer store may have a USB disk-drive enclosure or a USB hard-disk docking station so you can get at any of your data on the hard disk or SSD.

This approach is worth taking if you find that your desktop setup’s peripherals have a significant amount of mileage left in them or you use certain peripherals that fit your needs exactly.

Conclusion

Once you build out one or more desktop workspaces for your laptop computer, you are then able to have the best of both worlds – comfortable ergonomic computing at your desk and portable computing with your laptop.

The Sony SBH-52 Bluetooth Headphone Adaptor – OLED display to show time or details about what’s playing like the SteelSeries Rival 700 gaming mouse

Regular readers may have read my review of the Sony SBH-52 Bluetooth headphone audio adaptor which implements a monochrome OLED display to show the time or metadata about what what’s playing. Sony has also implemented this concept in a few previous personal-audio players as well as this Bluetooth headphone adaptor because of the fact that this display technology doesn’t take up much room in the device itself and could be best described as a “VFD display for battery devices” where it offers the same brightness as a vacuum fluorescent display while drawing minimal current.

SteelSeries have taken this further by implementing a user-customisable OLED display on the Rival 700 gaming mouse. Here, this mouse uses a special program to copy over game stats or a user-defined logo to appear on the display courtesy of the USB connection. Here, it is proving the idea that an OLED display can earn its keep on a small portable device even if the device is powered from another host device.

The Rival 700 gaming mouse also implements tactile feedback during gameplay so you can benefit from that convincing game effect but it is achieved in a manner to avoid disturbing your gameplay. As well, the mouse is designed for increased durability so you can subject it to intense gameplay or office work and SteelSeries offer it as something to equip your gaming rig or workstation for AUD$100.

Griffin provides a Bluetooth version of their USB control knob

Griffin Technology

My Comments

Griffin had taken advantage of USB’s devuce-class abilities to release a knob-shaped rotary controller which connects to your computer’s USB port.

Here, through the use of a control-mapping program, this controller allows you to either control your computer’s sound volume or use it as a scroll-wheel with documents or video material. For audio content, the knob has come in handy with audio-editing software due to the fact that it mimics the “scrubbing” action that used to be performed when editing open-reel tape. This effectively has replicated in some ways the “jog-shuttle” wheel found on most video-editing equipment and has become a well-liked accessory for people working with multimedia content.

Now they have taken this rotary controller further by making it be a Bluetooth wireless device. What I like of this is that they avoided the need to use a wireless dongle which is the common practice with most wireless mice and keyboards which limits interoperability with other computer systems and devices and creates something else to lose. As well, it implements the Bluetooth 4.0 protocol which allows for low-energy operation thus making the batteries less of a worry.

At the moment, Griffin’s website seems to make out that it is compatible with the Apple Macintosh platform only but they would need to port the function mapping software to Windows 7 and 8 to make this device have wider appeal. The Bluetooth 4.0 compatibility would also be applicable with the latest crop of Windows-based portable computers that are on the market which also implement this technology.

It is another of the accessories that pass by many computer users because they aren’t made readily available online or through mainstream computer outlets.

Last minute shopping ideas

Are you still at the shops looking for gifts to buy those loved ones? Have a look at this list of last-minute shopping ideas so you have something to give.

Headphones, Earphones and Speakers

Denon UrbanRaver AH-D320 headphones

Denon UrbanRaver AH-D320 headphones

Whether someone is working with a poor-quality headset or simply has lost or damaged their headphones, a replacement or additional headset can earn its keep.

Similarly the headset that they are using may not suit a particular activity they are doing like jogging or listening to content in a noisy environment. For example some headsets may earn their keep better for on-the-road use compared to other headsets or someone who does a lot of air travel or commutes by bus or diesel-powered train may appreciate the active-noise-cancelling headphones.

Bluetooth headsets can be of benefit to smartphone, tablet ad laptop users as a way to achieve private wireless handsfree communication. Why I mentioned tablet and laptop users is because of programs like Viber, Skype and Lync that allow for audio or video calls using these devices.  There are the Bluetooth audio adaptors that can covert a pair of wired headphones to a wireless headset and most of these come in the form of “Bluetooth in-ear headsets” which have these adaptors supplied with a pair of bud-style earphones.

Sony SA-NS510 Portable Wireless speaker

Sony SA-NS510 portable wireless speaker

Wireless speakers are still worth considering whethe they are Bluetooth-based or Wi-Fi-based, most of which serve as Internet radios under the control of a software app for smartphones and tablets. The cheaper variety can work as an ad-hoc portable listening device for a smartphone, tablet or ultraportable laptop and better-quality units can work well as an adequate secondary sound system for a small area. If you are buying a Wi-Fi-based unit, make sure that it supports AirPlay and DLNA or is a Wi-Fi / Bluetooth type that supports DLNA for Wi-Fi use.

To the same extent, a Bluetooth-capable radio can serve as an alternative to wireless speakers if you are thinking of something for the kitchen, workshop or office and you want access to broadcast or, in some cases, Intenret radio.

Input Devices

External hard disk

A typical external hard disk

One last-minute shopping idea for most technology users would be an input device of some sort like a keyboard or mouse. This includes Bluetooth keyboards and mice that come in handy for tablets and some smartphones or a small USB “multimedia” keyboard for a games console or some smart TVs and video peripherals.

Examples where they could benefit would be to create a “full-sized” workstation with a full-width keyboard for an ultraportable laptop or a tablet or a proper keyboard to use with a Smart TV or games console to enter in login parameters or social-media text on these devices rather than “hunt-and-peck” or SMS-style text entry.

Of course, they would earn their keep with replacing that half-dead computer keyboard, mouse or games controller thus benefiting from increased reliability.

Storage

The USB memory key always earns its keep as a removable storage solution for most devices especially if you are doing things like printing photos from your image collection at commercial photo-printing kiosks, using as a “virtual mixtape” for music to play in the car or on another music system or simply to keep certain important data with you on the go. Blu-Ray player users can use these USB memory keys to locally store downloadable BD-Live content peculiar to their own experience with the BD-Live disc and player. This could even allow them to take the same data between many Blu-Ray players which comes in to its own with BD-Live interactive entertainment that maintains local scoreboards or progress charts.

USB external hard disks also serve a purpose for providing offline backup of large amounts of data or offloading a large quantity of data from a laptop. This is more important with users who operate an ultraportable laptop that uses lower-capacity solid-state storage or for travellers who want to make sure they have a copy of the data in their in-room safe. Some smart TVs and digital-TV set-top boxes also benefit form USB hard disks simply to allow them to gain PVR functionality.

Similarly, most digital camera users and Android phone users would benefit from a spare SD or microSD storage card. The camera users can see these cards serving as extra rolls of film that can be swapped out at will where you can gain access to the photos for printing or downloading. For Android and, to some extent, Windows Phone, users, the microSD card can work as infinitely-expandable storage or, as I use them, as the equivalent of the mixtapes.

Covers, sleeves and other accessories

One simple way to personalise any portable computing device is to purchase ta cover, sleeve or pouch that reflects the personality of the user. In the case of smartphones, cases that look like a wallet or notepad also can add that look of something that exists alongside one’s wallet and other personal accessories.

Similarly, “gadget bags” come in to their own with people who has laptops, smartphones, tablets or digital cameras. These can be small “toiletry-bag-style” bags or “school-style” pencil cases that can be used to keep chargers, cables and other accessories “rounded up” and hard to lose to neat-looking camera cases that can keep cameras and their accessories protected.

As wit these, pay extra attention to the quality of the material, the stitching and any fasteners that are part of these accessories because a lot of cheaper poor-quality types easily become undone by stitching coming apart or zippers giving way. This is because these cases undergo a lot of use as people use their portable computing devices through life.

Other notes

Have a look at the Essential Smartphone Accessories gadget list that I recently published because these highlight the kind of accessories a person who has a smartphone or tablet can never be without. Of course, it is so easy to think that you should have a certain quantity of chargers, extermal battery packs or similar devices but they are the kind of devices you never have too many of and are easy to lose or not have with you at the right time.

If you know what they like for music, video material, games or books, the right title can fill the spot easily. In some areas like Australia and New Zealand, these earn their keep as Christmas is immediately followed by the main summer holidays that most people take and it becomes the time to enjoy these titles more easily.

Of course, if you are not sure of what to give a person, a gift card to an online app store, online music store or “bricks-and-mortar” music, games, technology or similar store can answer you gift-giving needs. Some gift cards such as the JB HiFi gift card can be exchanged for credit towards another storefront like an online app store like the Apple iTunes storefront. Similarly, vouchers to the same merchant from different can be added towards a more significant purchase.

Choosing the right input device for your laptop

Some of you may want to decide whether you want to use a laptop’s integrated trackpad or thumbstick as your pointing device on that computer. On the other hand, you may want to use an external mouse or trackball as your pointing device “on the go”.

Each device has its own application

Laptop trackpad

The laptop trackpad which is good if you are on the couch or in an airline seat

I would find that the external mouse can do the job better if you are frequently using your laptop computer on a table or desktop. This is more so if you are doing advanced graphics work and you find that these devices are easier to manipulate for this work and you have the benefit of the larger table or desk surface as your working area. Some of the external mice are available in a very small size so you can stow them in your laptop bag without them taking up too much room.

The regular mouse which works well at a table or desk.

The trackpad or other integrated pointing device can become more handy when you are in a lounge area or are travelling in a plane or train because you don’t have to worry about the extra mouse or trackball in these circumstances. As well, you don’t necessarily have the room to move a mouse around if you are confined to an armchair or sofa. In the case of working in a lounge area like the hotel lounge or someone’s lounge-room, you may get away with moving your mouse around the coffee table if the computer is on that table or on a thick armrest if the computer is on your knee.

You may find that the large ottoman like this one at QT Melbourne may work well with your mouse in controlling this Dell XPS 13 Kaby Lake edition laptop

It is also worth knowing that you may have trouble using your optical mouse on a glass table due to there not being any reflection or texture that the mouse can work with. You can work around this problem by placing a tablemat, napkin or piece of paper on the table and moving the mouse on that surface. This may not be of concern if you use one of those wooden dining tables that is finished off with a glass top.

A laser mouse which uses a laser as its tracking light is more flexible with different surfaces like glass tables than the regular optical mouse. There are newer technologies like Logitech’s Darkfield technology that are even more adaptive with glass tables whether they be the wooden table with the glass top or a desk or coffee table that just has a glass top.

What kind of connection

Wireless mouse dongle

The typical easy-to-lose dongle that comes with most wireless mice

When you choose an external mouse for use with your laptop, you could go for a USB-connected wired mouse or a wireless mouse. If you do go for a wireless mouse, I would recommend that you look for a Bluetooth or WiFi-Direct mouse like the Logitech Bluetooth Mouse M555b rather than the common type that come with a receiver dongle so you don’t need to carry around an extra dongle that you could easily lose.

This is due to the mouse using the laptop’s integrated Bluetooth or Wi-Fi circuitry as the connection path rather than something that is as big as a key and at risk of being lost.

Driver software

Most mice and other input devices don’t need to use any user-installed software for them to work with the host computer. Here, they just use class drivers that are integrated in to Windows, MacOS X or Linux for their basic functionality. Some of them may use a manufacturer-supplied driver for touch functionality or other advanced functions.

Batteries for your wireless mouse

Most of these wireless mice work on AA or AAA batteries so it is easier to get your hands on a set of the batteries for your mouse. You could just pick up a set of them from a drugstore or supermarket or ask Front Desk or Housekeeping for a set of these batteries if you stay in most hotels.

If you are using a wireless mouse, it may be worth running it on lithium batteries rather than the regular alkaline batteries. These allow the mouse to perform at its best at all times that you use it because they are adept at handling short bursts of short power demand. Similarly if you use it with a laptop that you only use during travelling, the lithium batteries have a longer shelf life.

Rechargeable batteries can come in to their own if you use the mouse very frequently such as with a main computer. Some of these can simply be charged on an overnight basis if you are using them daily. The chargers can be ran from AC power directly or there are some that run from a USB socket which would be handy if you have a laptop that uses a “sleep-and-charge” USB port or you use USB power supplies. Some newer wireless mice even have their own fixed-in batteries and are charged by connecting them to the host computer’s USB ports or a USB-based power supply.

All wireless mice will have an on-off switch on them. Here, you use this switch to turn off your mouse when you pack it in your bag for travel so you don’t find that the battery has run down. You will also find that if you haven’t used your mouse for some time, it will “go to sleep” to save battery runtime and will come alive when you press one of its selection buttons.

Conclusion

Once you choose and use the right input device for your laptop, you are then able to gain better use of the computer for the situation that you are using it in.

Is your mouse acting too “hair-trigger”? Check the Mouse settings in your operating system

On Saturday, I had been asked by a friend to help her out with her laptop computer and there were problems with her Outlook email client. After a bit of troubleshooting, I had found that I was single-clicking to open emails rather than doublie-clicking. She also mentioned that she was having similar problems with other applications on the same computer.

But what I had done was to check what is happening every time one double-clicks with the mouse by visiting the Mouse item in Windows XP’s Control Panel. The setup was a laptop which was also being used with a wireless mouse. So I selected the “Other Hardware” option which would pertain to the wireless mouse and adjusted the “double-click” speed for that mouse.

This is a problem that can happen with some mice and trackballs especially as they implement switches that have an increased rate of “contact bounce”, thus causing this false “double-click” behaviour.

Adjusting the double-click speed

Windows users should go to the Mouse option in the Control Panel then try double-clicking on the folder icon in that dialog box. MacOS users should go to {Apple]-System Preferences, then click on “Mouse“. Then try double-clicking on the display image in that dialog box.

Adjust the slider towards “Fast” if the folder opens and closes in one click and towards “Slow” if double-clicking doesn’t cause it to open. Then click OK or Apply to confirm the setting.

This may be a trial-and-error routine as you get the mouse or other pointing device working properly for you. In some cases, you may have to select the device you are using or use its software if you are maintaining two or more devices on the same computer. A common example of this may be when most of you use an external mouse with your laptop computer; or some of you may use two different pointing devices for different purposes such as a trackball and a mouse.

The best practice to do is to play around with this dialog box for your pointing device when you install a new device or acquire a new computer and revisit it to make sure that the double-click speed matches your needs properly.
