My Comments

Doncare Community Services, along with Doncaster Rotary Club, have just launched an iPhone app that provides information about domestic and relationship violence. This provides the general information that women need to know about handling these situations along with knowledge of legal and similar resources they can avail themselves of.

A typical situation that concerns online domestic-violence resources is that these resources are typically furnished as Web pages which can yield a privacy risk for the victim of this violence due to the fact that Web browsers list what you have browsed. This is a key risk for  lot of these victims who live in a highly-controlled abusive relationship. Here, the perpetrator is often likely to check on recent Web-browsing activity that the person has done on the computer equipment used in their home as part of wanting to know what they think and do as well as whom they see. These people even have to do this browsing from their workplace’s computer, a friend’s computer or a publicly-accessible computer like one installed in a library or café.

The native mobile app has the advantage that they can download the app from the platform’s app store, use it and delete it quickly if they fear that the perpetrator is snooping around their phone. Then they re-download the app from the app store as and when they can.

One limitation about this app is that it is focused on resources and legal options that are available and relevant to Victoria, Australia. An improvement that I would have would be to download information about options available in other jurisdictions, something that can be provided during the setup phase or at a later point. This effort could be positioned as part of a localisation effort that would take place during the app’s lifecycle.

At least this is an example of what can be done by family-violence support organisations regarding using the smartphone and tablets that people own. This is where a free, easily-downloaded, easily-uninstalled app that has this critical information and access to critical resources can be used as a tool by people who are at risk.

The calibre of the front-facing camera on a smartphone may determine its selfie prowess

Over these past months, smartphone manufacturers and the technology press have been going on about smartphones that are described as “selfie” smartphones. But what are they and what is this trend?

Like most of the consumer-technology companies, these companies are pitching the products at young people who are wanting to take many “selfies” which are pictures of themselves. This is mainly to provide the pictures that can be thrown up on Facebook, Instagram or other similar social networks or used as “avatar” images that are used to identify people on many games, instant-messaging and social-networking services.

Most smartphones have a front-facing camera along with a rear-facing camera but, in a lot of cases, the rear-facing camera has higher photo-taking abilities than the front-facing camera. This is because the front-facing camera has been purposed primarily for videocalls using 3G, Skype or similar services and has a resolution that usually maxes out at 3 Megapixels. As well, the lens systems in these cameras typically is a fixed-focus lens that may not yield good-quality pictures.

Some people get around this by typically having someone else take a picture of themselves using the rear-facing camera. This may range from another person in their group taking the picture or them roping in a stranger to immediately become familiar with the phone’s camera app and take that group picture. Or they may use other tricks like using a mirror or using the phone at arm’s length to take a rough shot.

What these “selfie” smartphones are all about is that they have a front-facing camera that is optimised to turn out high-quality still pictures along with logic to make the act of taking these pictures easier. The cameras will typically have resolutions of at least 5 Megapixels and, in some cases, there are some phones emanating from China that have 2 13-megapixel cameras. The lenses in these cameras even are optimised to take the best selfies by using a wide-angle design. Some of the Android phones implement camera logic to take improved shots with the front camera like removing blemishes for example or managing the rear camera to take those selfies like implementing a self-timer.

Personally, I would look towards using whatever post-processing functionality like cropping to get the picture right before tendering it to that social-media site because you may not get the framing right. This is more so if you are using your device’s rear camera to take these shots and you don’t have the help of someone else to take that picture.

In Case Of Emergency opening screen

I am highlighting the emergency-notification apps like “ICE In Case of Emergency” which are available for most smartphone platforms along with other techniques to make your smartphone work with you if you are caught up in a medical emergency or disaster.

What are these apps?

These apps provide access to information that is essential for others to know if an emergency occurs. Typically the apps work with a lock-screen that provides immediate access to this information along with the necessary space to store that information on our smartphones. As well, they keep the phone’s security functionality in place by providing “sandboxed” access to the emergency information but you can gain full access to your phone using the regular passcode that you have for it. This “sandboxed” access may only allow you to dial the contacts listed in the app’s contact list from that app when the phone is locked so you can still contact them in case of emergency.

In Case Of Emergency app widget on lock screen

They store information about whom to contact in case of emergency, illnesses or other conditions that others should be aware of, medical contacts along with information about the medicines that the person on the file is taking. They may even have the ability for you to directly dial the emergency contacts from their user interface. Some more sophisticated variants may work with a cloud service and your phone’s location identification features to transmit your location to loved ones in case of emergency.

Most of these apps are available from the mobile app stores for pennies’ worth or, in some cases, for free. On the other hand, you can add text to your phone’s lock-screen wallpaper with your emergency-contact information so this is available at all times even when your phone is locked. There are apps that can facilitate that by “mixing the text with the pictures”.

Who are they useful for?

One group of people they are essential for are those of us who have chronic illnesses which can result in an unpredictable emergency situation like a coma, seizure or asthma attack. This includes elderly people who are at risk of a stroke or something similar that is brought on by the ageing process.

Here, it means that when they are out and about, they are sure that the people they are with are able to contact someone like a close friend or relative or their doctor to find out what to do in relation to helping them through the situation. As well, they can convey the critical information to the paramedics or safety / security staff who are managing the situation.

I had one of these apps on my phone because of the fact that I have epilepsy and am at risk of the seizures associated with that illness. This came in handy recently when I had one of these seizures during a group get-together at the church I attend and two of the fellow congregants were able to know whom to contact and what to do by the easily-accessible information that the app was able to provide. This was even though they had called an ambulance to attend to this situation.

Another group of users that would benefit from these emergency-notification apps would be those of us who do activities like bushwalking, long-distance running and long-distance cycling. Similarly people who do a lot of travel can benefit from these apps. These kind of activities may require others to know whom to contact if something untoward happens to them.

In all these situations, a hard-copy card that you keep in your bag or wallet and carries the same essential information does work well as a backup in case your phone runs out of batteries or “freezes”.

What to look for with these apps

These apps should have the ability to retain all of the essential information like your name, the phone numbers for at least a few contacts including your primary-care and other-care doctors, along with identity numbers for national / universal health (NHS, Medicare, etc) or other coverage. As well they should be able to keep information about your blood type and other general medical particulars along with information that is essential to treating and managing your illnesses.

As well, they should be able to have the ability to provide off-device backup storage of this information, whether on removable media or a cloud-based storage service. This is to cater for situations where you may upgrade your phone or your phone plays up and destroys the data. To benefit international travellers, the software could keep information like your passport number and “home country” details along with travel insurance contact details.

Another feature that a good emergency-information app should have is the ability to be dynamically switched between different languages. This can be of importance in countries which maintain multiple tongues or have a multicultural society, or for travellers who are travelling in to countries or territories where their home tongue isn’t spoken.

Conclusion

Your smartphone can work as an emergency reference book for others to use if you are stricken through some situation. All it just requires is the use of an emergency-info app and / or using a customised lockscreen wallpaper with the critical information on it.

This is the first of a series of posts to celebrate the last five years of the connected lifestyle which has been covered on this Website.

Laptops

Lenovo Yoga 2 Pro convertible Ultrabook

Over the last five years, the 15”-17” clamshell-style laptop computer has overtaken the traditional “tower-style” desktop computer as become the preferred computer style for most households.

There are even users, some of whom I know, who will operate these computers in conjunction with an external screen, keyboard and mouse for their primary office-based computing locations while being able to use just its built-in screen, keyboard and mouse for computing while “on-the-road”. In other cases, the laptop bas brought with it the appeal of the dining table or kitchen bench rather than a home office or a desk in the corner of the family room as a workspace due to the ability to stow it away when you are using that space for other activities like meals.

Dell Precision M2800 – an example of a mobile workstation

With this class of computer, there has been the rise of “workstation-grade” and “gamer-grade” laptops that are tuned for increased performance, especially with graphics-intensive tasks or even “full-on” games. This has also displaced the desktop workstation computer or “gaming-rig” for these applications and allowed for increased portability when dealing with CAD, multimedia or games.

Windows 8 with its tile-based “Modern” user interface has legitimised the touchscreen as a control surface for the computer and has opened up a plethora of touchscreen-enabled laptop designs. For example, the Sony VAIO Fit 15a that I reviewed last year underscored the concept of adding touch abilities to a 15” mainstream laptop even as I let a friend who works in enterprise IT play with this machine when I had visited him.

This has also led to the arrival of convertible and detachable computer designs that switch between a traditional laptop design and a tablet design. There are even these convertibles that have 13” or, in some cases, 15” screens which may be considered too large for tablet use by one person but are the right size for creating content. In some cases, this size can appeal to those of us who want to let another person have a look at the same content.

The trend has led to a fusion of regular desktop-style computing and mobile computing with some laptops running Android whether standalone or on a dual-boot method. As well, some small tablets are being sold with Windows 8.1 as an operating system and it is being harder to differentiate between mobile and regular-grade computing capabilities.

Mobile computing

One main trend over the past five years has been the arrival of platform-based mobile computing, which was commercialised by Apple with their iPhone platform.

Samsung Galaxy Note 4 – an up-and-coming Android smartphone

It is where devices like mobile phones and tablets are built around an operating system which has many third-party programmers writing software for these devices. Typically the software is supplied through “app-stores” operated by the company who develops the mobile-computing platform and these “app-stores” are typically one-touch away from the user. The software, which is referred to as “apps”, typically ranges from productivity software like email clients or note-taking software, through utility programs like calculators or unit converters, and mobile front-ends for online services to games for whiling away those train journeys.

Google Play Android app store

If the programmer wants to monetise their creation, they have the ability to sell it through that app-store which has an integrated e-commerce setup, sell modules for that software through “in-app purchasing” where the user can buy the option within the app’s user interface but via the app-store’s storefront or make use of an in-app display advertising setup.

Some of these app-stores or the apps available in them provide access to content-retail services where you could buy music, audiobooks, e-books and videos to enjoy through your device. For example, the e-book has appealed mainly to women who like to read romance fiction without that “tut-tut-tut” from other people about what they are reading.

The performance calbre of these mobile-computing devices is approaching that of the regular computing devices, especially when it comes to playing hardcore games or watching multimedia content. Here, we are seeing mobile devices being equipped with 64-bit ARM-microarchitecture RISC processor units or some Android devices being equipped with IA-64 microarchitecture chips similar to what most laptops are equipped with.

Smartphones

These devices have changed since the arrival of the iPhone with customers being spoilt for choice in device capabilities, operating systems and even screen sizes.

Firstly, you can purchase smartphones with a screen size of up to 6 inches and these are the same size as an advanced-function pocket calculator such as a scientific or financial type. As well, some of the premium smartphones, especially those from the Samsung stable, even implement the OLED display which is a different self-illuminating display technology to the LCD display which requires LED backlighting to illuminate it.

As well, there are smartphones that run Android or Windows Phone operating systems available from many different manufactures. For that matter, the smartphones that are considered “cream of the crop” nowadays are most of the newer Android phones made by Samsung, Sony or HTC.

Tablets

Toshiba AT1S0 7″ Android tablet

The mobile tablet has been made commercially viable thanks to Apple with their iPad lineup. Here, we are now seeing tablets at various different price ranges and screen sizes courtesy if intense competition. Some of these units, when paired with a Bluetooth or USB keyboard have been able to become a viable alternative to “netbook-size” small laptops.

Firstly, I had seen the arrival of the 7”-8” mini-tablet that could be stuffed in to one’s coat pocket. These have appealed as units that can be useful for reference-type applications when you are out and about and have effectively displaced the e-reader as a device.

Secondly, the 10” tablet has become more of a household content-consumption device especially with video but also has served some basic computing tasks like checking email or Web browsing. Apple and Samsung have raised the bar for this product class by improving the display calibre with the former using a high-resolution “Retina” display on their 3rd-generation iPad lineup and the latter offering an AMOLED display on a 10″ mobile tablet.

Samsung Galaxy Tab S 10″ tablet

But, as I said earlier, the tablet and laptop are bridging together as a portable computing solution. This has been brought about with the convertible and detachable computers that can be a tablet one moment or a laptop another moment. Similarly, Intel and Microsoft have pushed the classic desktop microarchitecture and Windows 8 in to the field of the small-sized tablets with chipsets optimised for portable computing and the availability of Windows 8.1 for free with small-screen tablets.

Moble-Platform apps

The mobile platforms have seen a cottage industry of developers write programs or “apps” for these devices that can fit in with our lifestyle. Some of these apps have become mobile “on-ramps” to various online content services like social networks. As well, the e-reader has been displaced by the “e-bookstore” apps written for the mobile platforms so one can use a tablet or smartphone for reading whatever they want to read without worrying.

Recent controversies have arisen regarding how these apps are sold such as the issue of “in-app” sales of downloadable content or virtual currency for games that appeal to children or ad-funded apps that may host advertising that “commercialises” childhood like the sale of toys or junk food. As well there have been issues raised about the quality of apps sold through the app stores with computing “old-timers” relating them to the download sites, bulletin boards and magazine-attached disks of yore.

Wi-Fi an important part of the home network

For that matter, the most important feature of any network, including a home network, is a Wi-Fi wireless-network segment. This has enabled us to do more around the house with laptops, tablets and smartphones yet use cost-effective fixed broadband Internet.

These networks have increased in speed and security courtesy of newer technologies like 802.11n, 802.11ac and use of both the 2.4GHz and 5GHz bands. The setup procedure has been simplified for these networks courtesy of WPS-PBC “push-to-connect” setup and the upcoming NFC “touch-to-connect” setup technologies.

Increasingly more networked devices are being designed to work primarily or solely with the Wi-Fi network segment because of the “no new wires” concept that this technology provides. This technology also appeals to the mass-market retailer as an easily-saleable “backbone” for the home network even though there are issues with the radio-network performance.

Mi-Fi devices and the portable Wi-Fi network

Another class of device that is becoming popular is the “Mi-Fi” router which is a portable battery-operated Wi-Fi router for a mobile broadband service. These have appealed to those of us who use temporary network setups with Wi-Fi-only tablets and laptops or simply want to run a mobile-only communications setup.

This has also extended to the arrival of portable NAS units that work as extra storage for smartphones, tablets and laptop computers but work as their own access points for these devices. Manufacturers are even pitching them as a way to store video content on the mobile NAS unit and having people like children view the content on their tablets via the small network that is created by these devices.

The next part of this 5th-anniversary series will liook at the concept of “connected” communications and entertainment and how the home network is playing a strong part in these activities.

Wi-Fi group acts to simplify peer-to-peer video, printing and other tasks | PC World

From the horse’s mouth

WI-Fi Alliance

Press Release

My Comments

A current limitation that faces anyone who uses Wi-Fi Direct peer-to-peer networking is that the users have to face many steps to take advantages of the devices they connect to. This typically includes being able to discover the device, what it does and how it can do it, such as printing abilities or display resolution. In the case of Miracast-capable displays, this may also include “opening up” the input associated with the Miracast functionality to have the computer’s display on that display screen.

The Wi-Fi Alliance have revised the Wi-Fi Direct specifications to provide task-focused operation with the equivalent of class drivers. This is although there are standards like the UPnP Device Control Protocols out there to enable this functionality and this revision is to specifically enable “one-touch” access to the device’s function.

At the moment, the Alliance have defined four specifications:

• Wi-FI Direct Send – for sending and receiving content with minimal user interaction
• Wi-Fi Direct Print – to print quickly from mobile device with minimal interaction
• Wi-Fi Direct for DLNA – to make it quick to discover DLNA-capable resources like the wireless speakers to play content through these devices
• Miracast – to allow for screen mirroring and use of an external display

A good question is whether these task-focused specifications only reflect on setups that implement the peer-to-peer connectivity offered by Wi-Fi Direct or whether they could extend to Wi-Fi LANs such as when you use a Mi-Fi device or home network.

At the moment, the new abilities can be applied to existing devices through the use of newer firmware versions because these abilities are offered on a software level rather than through newer hardware requirements. As well, Samsung and other Android vendors could integrate the NFC ability and the Wi-Fi Direct Send functionality to provide a platform-wide implementation of the “S Beam” file-sharing functionality.

Microsoft Universal Mobile Keyboard

Microsoft have designed a Bluetooth keyboard that is intended for use with smartphones and tablets that run on the three main mobile platforms: Android, iOS and Windows 8. This is to cater for a reality where people may operate different computer devices on different platforms.

Microsoft have achieved a universal layout with platform-specific keys for Android and iOS, like the Command (snowflake) key that the Apple platforms need. The Windows or Android modes could work with devices like games consoles or Smart TVs that implement Bluetooth Human Interface Device Profile in the context of a full keyboard for text entry. What could this mean for using your smart TV’s social-network or content-search functionality without “hunt-and-peck” operation.

But you can select between the different operating systems and keyboard layouts using a three-position hardware switch. As well, the keyboard remembers Bluetooth pairings with 3 devices of the different platforms.There is even a rest for your tablet or smartphone so you can see what you are typing and this works as a lid for the keyboard.

Of course, it can run from its own battery for 6 months but can allow you to quickly charge the keyboard to gain 8 hours extra runtime.

But most of us who use keyboards with tablets typically head for those keyboards that are integrated in a case for the tablet and Microsoft could do better to offer this as a case for most 10” tablets.

Introduction

I am reviewing the Lenovo Yoga 2 Pro convertible notebook which is Lenovo’s latest in its lineup of Yoga 360-degree convertible notebooks. This convertible notebook is a 13” portable-typewriter-size unit in a similar vein to the Sony VAIO Fit 13a convertible, with the idea of a screen and keyboard that is comfortably large for creating a significant amount of written content but also appeals as a large-screen tablet.

There is a baseline package which comes with the Intel i5 processor, 4Gb RAM, and 128Gb solid-state drive which is packaged in a 1960s-era orange housing (feelin’ groovy), along with a premium package that has an Intel i7 processor, 8Gb RAM and 256Gb solid-state drive which is packaged in a silver-grey housing. These product variants are available through the retail sector. But you purchase a package which has the Intel i7 processor, 8Gb RAM and 256Gb solid-state drive but fashioned in the orange housing directly from Lenovo’s online storefront.

The computer itself

Aesthetics and Build Quality

As a tablet

The Lenovo Yoga 2 Pro is a 360-degree convertible notebook that has the keyboard swing behind the screen to become a tablet. This also allows for setups like a “viewer” setup with the screen at a convenient angle but the keyboard not jutting out or even as a “tent” setup with the hinge at the top of the screen like a table tent-card. This mechanism has been able to operate smoothly with the display changing quickly and responsively.

As a viewer

It has the rubberised feel on the outside and on the palm rest with a distinct non-rubber feel for the actual keys and trackpad area. This make the computer so much easier to operate by touch.

As a tent card

The base-model Lenovo Yoga 2 Pro comes in that bright orange colour that was a well-favoured colour for cars, appliances, furniture upholstery or interior design through the 1960s “Flower Power” era. The premium model with the higher specifications comes in a silver-grey colour. But people can order a higher-specified model with that bright-orange colour when they buy the computer directly from Lenovo’s online store.

The Lenovo Yoga 2 Pro does keep its cool properly due to a ventilation grille installed between the hinges. This can be uncomfortable to use when you are operating it as a tablet and holding it like a book.

User Interface

Like most computers that have the 13.3” screen size, the Lenovo Yoga 2 Pro has a keyboard that is comfortably large for fast touch-typing and creating of large amounts of written content. It does feel shallow but you can still have the proper tactile feedback to adequately touch-type.

The trackpad is still very responsive but could have hardware override especially if you are touch-typing quickly and use the touchscreen and / or an external mouse to navigate the user interface.

All the supplementary controls are located on the right edge of the computer with buttons for just the volume control and to turn the computer on and off as required. Personally, I would like the on-off button to be easier to identify by feel and this could be preferably a larger button.

Audio and Video

The Lenovo Yogo 2 Pro’s display was very responsive and true to colour when watching online videos but the desktop experience on the high resolution display is stymied by the way most current-generation desktop operating systems like Windows handle high-pixel-density displays. This is where they make the text smaller and, in some cases, harder to read.

The sound does come through clearly for most voice based content when you are listening close to the computer but if you want to get more out of the music or good game effects, I would suggest that you use headphones or external speakers.

Connectivity, Storage and Expansion

Right-hand side – Power switch, Volume buttons, 3.5mm audio jack, USB 2.0 port

There is a USB port on each side of the Lenovo Yoga 2 Pro with one of each type allow for a common reality where one could be using a wired mouse and something like a USB external hard disk to offload extra data while travelling.

The model I am reviewing came with 256Gb of solid-state storage which was quick and responsive. The cheapest model has a 128Gb solid-state drive which would work well just for documents that you create but you may have toe eventually need a USB external hard disk. This is augmented by an SD card reader which comes in handy with your digital camera when you want to quickly download your pictures to take them further.

Battery run-time

Left-hand side – power connection, USB 3.0 port, microHDMI socket, SDXC card reader

For a highly-portable computer, I am able to complete most regular computing tasks like text editing and Web browsing on the Lenovo Yoga 2 Pro without finding I am out of “juice”. Some tasks like continual gaming or video watching may place a bit more strain on the batteries here.

Other usage notes

From my observation with different people, the Lenovo Yoga 2 Pro has yielded different levels of interest. This ranged from a perception of it being too heavy to something that appeals as a flexible large secondary computer.

For example, it has been seen to be heavier than other devices that some people are used to using as secondary or companion computer devices like the Apple iPad. Conversely, a friend of mine whom I stay with liked the idea of the 13” convertible form-factor with it able to be a large easy-to-see tablet or something to type copy on.

But the Yoga 360-degree convertible design has piqued some curiosity because of the way it operates causing the system to be a tablet or a laptop computer.

Limitations and Points Of Improvement

There is always the problem with the 13” ultraportable laptops being a bit too pricey compared to other computers of smaller or larger screen sizes. This is although they are likely to be considered as secondary computers for those of us who use desktops or larger laptops. The Lenovo still doesn’t change the fact here when it comes to the price of these computers.

Lenovo could offer a step-up model with the Intel i5 processor, 4Gb RAM and a 256Gb solid-state drive and / or offer an entry-level model of the Yoga 2 Pro with the Intel i3 processor for those of us who see it more as the secondary portable computer. It could also be the beginning of a run of colourful convertible notebooks that appeal to the idea of a highly personal computing experience.

Conclusion

Rear view – feelin’ groovy orange

The Lenovo Yoga 2 Pro computer would still come in to its own as a valid option for a secondary computer to create content on even though you have a larger “at-home” desktop or laptop computer, or as a large-screen tablet. Even the entry-level model is worth considering for those of us who value them in this way but want to save money.

The 360-degree convertible mechanism would be of value for those of us who value a convertible or detachable computer that is simple and hassle-free to switch between operation modes. This is especially important for those of us with limited dexterity  or are easily confused.
