In the early 1980s, the BBC undertook a computer-education project which was based around a series of television programmes along with a specially-commissioned computer. This computer, known as the BBC Model B computer and built by Acorn who were a relatively-new home-computer manufacturer in the UK, was sold to schools so that students can work along with the TV programmes which explored, amongst other things, coding in BASIC and interfacing and controlling other devices.

One feature that the BBC Model B had was an 8-bit user port which was used for directly interfacing digital circuits along with a “game port” typically used for analogue joysticks and knob-style “paddles” but serving as an analogue input. Some of the printed and visual courseware associated with this computer was dedicated to teaching how to use these “real-world” interfaces.

This system was Acorn’s main founding stone and Acorn evolved to become a company who sold RISC-based microprocessors and defined the ARM microarchitecture used in most of today’s smartphones, smart TVs and similar devices.

But Acorn had clawed back to their roots with an ARM-based pocket-sized board computer similar to the Arduino and Raspberry Pi. This computer has been developed in conjunction with the BBC in order to continue on the legacy left by the original BBC Model B computer.

It has 25 LEDs that can be programmed to light up and flash messages, 2 user-programmable buttons and sensors in the form of an accelerometer and compass along with input-output connections for users to connect to other circuits. It uses Bluetooth Smart (BLE) technology to interface with other devices including regular and mobile computer devices. As well, it can connect to a computing device via USB and be programmed via a browser-based software development kit called TouchDevelop which Microsoft worked on.

The TouchDevelop setup uses the Web-based interface along with a choice of programming languages as a way to program the device. It also involves two-stage compilation with the Block Editor script being compiled to turn out C++ code which is then subsequently compiled and linked to turn out machine code to be downloaded and flashed to the BBC Micro Bit.

Like the previous BBC Model B computer, this will be delivered in to UK secondary schools and students will have their own Micro Bit computer so they can learn how to program the Internet Of Everything as part of their computer education.

The goal is to have this computer replicate what the BBC Model B computer had done for British computer education and the success in bringing about a UK-based software industry. Here, they want to have Britain putting a clear foot in the door for Internet Of Things.

My Comments

Soon it will be feasible for Bluetooth and NFC “touch-and-go” authentication to play a part in open-frame multiple-factor authentication thanks to FIDO Alliance. This is primarily to court those of us who are using mobile devices and want the same level of security as valued with regular computers.

The main goal of the FIDO Alliance was to get the USB transport interface working properly but then to have it work across other transports like Bluetooth and NFC? This is due to most mobile devices including an increasing number of laptops and “2-in-1” computers, coming with Bluetooth including Low-Energy (Bluetooth Smart Ready) and NFC functionality along with Android and Windows exploiting NFC functionality fully at the operating system level.

Example applications made feasible with Bluetooth and NFC in the second-factor authentication sphere include:

  • use of a “touch-and-go” card or a Bluetooth keyfob as your second factor for authenticating to a service from your regular computer or your mobile device – the device doesn’t need a standard USB socket
  • a smartphone that uses a software “second-factor” authentication program like Authy could transmit the second-factor code to your regular computer or tablet by Bluetooth or NFC “touch-and-go”.

As well, the fact that smartphones have a hardware (SIM-based) or software secure element means that they can become as much a strong partner in your data-security arsenal. The concept is also being extended to the idea of devices like smart locks and cars having the Bluetooth and / or NFC abilities along with an onboard secure element of some form.

Similarly the U2F and UAF specifications could earn their keep as a transport for other dedicated-purpose devices like smart locks which typically are implementing Bluetooth Low Energy and/or NFC technology as part of their presence in the Internet Of Everything. This can open up paths of innovation for integrating such devices in a personal-security web of trust.

Pikes Peak International Hill Climb

Press Release

My Comments

This year’s Pikes Peak International Hill Climb in Coloradio Springs, Colorado, USA has become an interesting race when it comes to enriching the spectator’s experience.

It has been facilitated by the use of Bluetooth Beacons or iBeacons along with an iOS 8+ iPhone app which provides detailed up-to-date information about the competitors and where the place during the race. This includes the ability for users to favourite a competitor and be notified when they hit the finish. The Bluetooth Beacon technology is pitched as being Internet-independent because there isn’t the need to have the vehicles equipped with GPS-capable devices and spectators’ smartphones can pick up these beacon signals easily.

.. like bike races of the Tour De France calibre

But I do see more potential for this in rallies, hill-climb races, road-based cycle races, marathons and similar point-to-point races. This is where competitors are required to race from one point to another and following a known route or series of waypoints. Here, spectators would typically be spread across the (typically long) course and would want to know when their favoured competitors are coming past them as well as knowing how they are placed in the competition.

The same technology can work with other computer systems to accurately determine who has won the race without requiring the use of proprietary transponder technology. As well, there isn’t a requirement for competitors to carry and use GPS devices that need continual mobile-broadband links for uploading real-time position data, something that would be difficult with events held in country areas where such service isn’t all that reliable. The other bonus is that the Bluetooth beacons are very lightweight which adds very little weight to the competitor or competing vehicle where any extra weight carried can slow the competitor down.

But the hillclimb allowed spectators with suitably-equipped mobile devices that supported beacon detection to detect these beacons themselves when it comes to when “their” competitors are near. As well, computing devices with Bluetooth Smart functionality and Wi-Fi / mobile-broadband Internet access can be located at key points in the course to report the competitors’ positions for real-time updates for broadcast and online use.

It does show that the idea of using the Bluetooth Beacon technology for tracking the competition in point-to-point races has been proven thus allowing for systems that are more affordable for providing real-time competition updates for the spectators. It could be that as you watch that car rally you could have you phone notify you when that rally legend is near and about to perform that 3-point turn in the WRX. Similarly, your phone would notify you as the Tour De France péléton is about to arrive in your street so you can flip open those shutters and windows on the front of your house to have a look as it comes past.

For it to work effectively, the Bluetooth Beacon technology needs to be able to work on the client side with iOS, Android and Windows platforms with the necessary client apps written to work on each of those platforms.

A smart-lock solution arrives for the Euro-standard mortice lock

My Comments

At the moment, most smart-lock solutions are catering towards the “bore-through” cylindrical deadbolt that is common in the USA and some other countries.

But there is an established “open-frame” cylinder-mortice-lock platform, known as the “Euro-profile” platform, which has a strong presence “across the board” in most of Britain and Europe and has some presence in Oceania. This is based around a single-piece module that houses the key cylinder and / or a thumb-turn which slides in to a mortice lock or multi-bolt locking system already installed in to a door. This platform hasn’t been served by this technology until now.

La Poste, the French post-office, have started marketing a smart-lock kit as part of their foray in to the connected-home scene. This is based around a “swap-in” module that replaces the cylinder module or cylinder / thumbturn module that is part of a European-standard mortice lock or multi-point locking system and, like some of the other smart locks, works with a fob or your Bluetooth-linked smartphone dependent on the package.

Here, the hardware based around a high-security outside cylinder module which “drives” the lock’s bolt and provides access using a traditional key. This interlinks with an inside module that has a thumbturn along with the electronics including the Bluetooth Smart radio subsystem that is part of the PostAccess system. It also has an integrated door-alarm which can be set up to work as a simple “buzzer alarm” that sounds when someone opens the door, or it can simply be set to sound if someone attempts to force the door open.

It also works with an NFC card reader that looks like a wireless doorbell and comes with the PostAccess Sérénité package. This card reader actually links with the lock using Bluetooth Smart technologies so it can read NFC cards, badges or wristbands and use these as keys.

People who buy the PostAccess Services Connectée package also receive a Wi-Fi – Bluetooth bridge that links the lock to your home network, This allows for you to manage your PostAccess lock remotely through a Web portal that is set up by La Poste in France. The standards around the online service encompass a high-security data transfer setup between the PostAccess smart lock and the servers which are located in France.

What I like of this smart lock is that it is the first product of its kind to work with the Euro-profile cylinder-mortice-lock platform purely on a retrofit basis in a manner that suits a “screwdriver expert”. As well, it is the first product of its type to be a hub for two peripheral devices i.e. the NFC card reader and a home-network bridge while working with smartphones for authentication and management purposes.

Like other early entrants in to the network-based connected-home or “Internet Of Things” idea, it will show the problems and bugs associated with these devices. This is where you rely on particular vendor-supplied equipment, smartphone apps and services to get the full benefit from them and they don’t work on an “open-frame” platform. To approach this better, the manufacturers would need to make the PostAccess smart lock software-upgradeable to newer “open-platform” standards

La Poste could be seeing this as a way to get their foot in the door to the connected home rather than trying to run their own “n-box” triple-play Internet service in to a highly-competitive Internet-service market. They could take this further with other products of the connected-home class and / or build out their Services Connectée package for remote home management.

To make the “smart-lock” idea work, there has to be an emphasis on seeing more products of this class appear on all of the commonly-used form-factors that the typical door lock appears in. As well, there has to be the ability to see the connected-home “Internet-Of-Things” concept mature on a level playing field along with encouraging a distinct role for these devices in the connected home.

Bluetooth Smart technology to detect if Grandpa has the wanders

My Comments

A 16-year-old had developed a device which alerts someone else if a person like an Alzheimer’s patient wanders out of bed. This boy, Kenneth Shinozuka, was inspired to develop this device because of an incident where he was out with his grandfather at age 4 and Grandpa wandered off and was lost. Here, this brought to his family’s attention that Grandpa had Alzheimer’s disease.

A situation that was very common for him and his family was that his aunt who was his Grandpa’s primary carer wasn’t sleeping properly because she worried that if she slept, he would climb out of bed and wander absent-mindedly.

Here, he designed the device to be attached to the patient’s sock, slipper or foot to sense foot pressure associated when they climb out of bed to start wandering. This device uses a Bluetooth Smart (Bluetooth Low Energy) link to a suitable smartphone that is equipped with an “alarm” app that audibly alerts the carer and shows up a timer to show how long they have been off the bed. There is the ability to set up a threshold and a “hold time” so as to allow for situations like the patient going to the bathroom at night to do what he has to do.

He developed this device through a few science fairs including the Google Science Fair where he got the respect and was given the Google Science Fair Global Finalist prize amongst a few other awards. Scientific American and Popular Mechanics, both respected science and technology magazines even gave him awards for this device. He was able to use the prototype with his Grandpa and his aunt in this situation and she was able to claim a lot more sleep each night because of not worrying if he was about to get the wanders overnight.

Kenneth saw this as being important for the “ageing at home” phenomenon where older people are staying at home in the care of family members and friends rather than going in to care at nursing homes or similar facilities. He is evolving the technology towards other aspects of this phenomenon like a bathroom floor that senses if someone is falling and a medicine box which alerts the older person to take their pills at the right time.

Two more interesting smartwatch designs are surfacing

HP and Casio are each premiering a smartwatch that, like Swatch’s and Tissot’s idea, are different from the pack. One of these is a something that would be kept as a dress watch to wear when you are going out while the other one can identify those tunes playing on the radio or background-music setup while you are out and about.

My Comments

The first of the watches is a luxury fashionable dress watch that is engineered by HP but designed by Gilt along with the fashion designer, Michael Bastian. This men’s watch has a round 44mm stainless-steel case and swappable leather bands, taking with it the “stylish yet cool” interior designs associated with some of the recent luxury cars out there.

For functionality, this is meant to interlink with iOS and Android devices using a platform-specific device, this courting the luxury market’s penchant for preferring the Apple iPhones as their smartphone options. At the moment, this watch offers notification functionality for email, text and calls along with being a control surface for music playback and some other apps.

Personally I would see the HP watch’s emphasis on style rather than geekiness more about either the watch to wear when you are going to the Melbourne Club or wanting to take out someone whom you are really trying to impress.

The second of these watches is Casio’s latest G-Shock smartwatch. This has notification functionality through its LCD display which exists behind the traditional clock face and also acts as a control surface for your phone, especially with your music using a knob on the edge of the bezel. It would work alongside a Casio-supplied platform-specific app for your smartphone and maintains the rugged look of other G-Shock watches.

But it also works along with SoundHound and an internal microphone to identify the music that is playing. Once identified, the song details appear on the watch’s LCD display.

The Casio watch would be on a par with other Android Wear smartwatches but has a long battery life thus avoiding the need for you to charge it every night. It would look the part more as a utility watch for everyday activities.

At the moment, these watches along with the previously covered Swatch watches come across more as baseline “control and display surfaces” that link to your smartphone using Bluetooth 4.0 LE a.k.a. Bluetooth Smart. But they would require the use of different apps to provide the software connection. Personally, what Google, Apple and Microsoft should work on is a baseline wearable specification which allows different wearable devices offering baseline functionality to link to the phone without the need to run many extra apps. As well, the watches should at least support using the phone as a “reference clock” for setting the time and adjusting for different time zones and daylight-savings time.

What is happening is that there are smartwatches that place less emphasis on the “geek nature” and could expose this genre of product to most of us.

My Comments

The smartphone is about to be married with the slot-car race set by providing a way to help you improve how you race with these sets. The functionality allows for simulation of various motor-racing conditions like fuel-supply. tyre-wear and vehicle damage, yellow-card conditions and the like. It also allows for one to engage in a variety of different motor-race competitions like Grand Prix races, “qualifying” races, drag races and endurance races.

This is achieved through the use of an iOS/Android smartphone or tablet that links to the power-base via Bluetooth 4.0 LE a.k.a. Bluetooth Smart technology. This is facilitated with an app that provides the advanced control abilities. They also use a wireless link to the handheld controllers which are still used by the competitors to control their vehicle’s speed on the track.

This unit is able to work with any standard 1:32-scale slot car track by allowing a user to replace a power base used in the existing layout with this power base. Here, the user just has to swap in a “full-straight” part of the track for this device. The Digital RCS Pro system, which offers more control, uses a special chip to be installed in the actual cars themselves, with most of the recent cars having “plug-and-play” installation.

What this has been highlighting is that today’s smartphones are being able to work with some of the “old-school” hobbies by offering extra functionality and capabilities.

Bluetooth 4.1 to support Internet Of Things

Sony VAIO Duo 11 with Bluetooth 4.0 connectivity that can be upgraded to Bluetooth 4.1 through a software update

Recently, the Bluetooth Special Interest Group have released the Bluetooth 4.1 specification which is intended to capitalise on the low-power devices application that Bluetooth 4.0 was known for, but improve on useability and reliability.

With Bluetooth 4.0, it allowed the development of low-powered “Bluetooth Smart” devices that work with a “Bluetooth Smart Ready” device like a smartphone or tablet that serves as a hub for these devices.

This is intended to be a software-based upgrade so that an operating system, device firmware or driver software update could bring a Bluetooth 4.0 device up to date to this newer standard. It is compared to previous Bluetooth standards which affected the silicon that was installed in the device.

But what are the improvements?

Reliability

Kwikset Kevo cylindrical deadbolt in use - Kwikset press image

This Bluetooth 4.0-capable smart deadbolt can work with “hub” devices that are updated to Bluetooth 4.1 specification

A Bluetooth 4.1 subsystem can co-exist with an LTE cellular connection used for mobile broadband services without suffering or causing near-band interference which could ruin the user experience. This is catering to the increased rollout of the LTE-based 4G mobile-broadband services by many cellular-telephony carriers, the integration of LTE-based 4G modems in well-bred smartphones and tablets and the popularity of these services amongst users.

This is also augmented by use of longer time windows for inter-device handshaking so that there is less risk of the connections between devices being “dumped” and requiring users to manually pair the devices to each other again. The devices also connect with each other when they are in proximity to each other without extra user intervention beyond just powering-on devices that were powered off.

Functionality

One ability that Bluetooth 4.1 adds to Bluetooth Low Power devices is to support bulk data transfer in this class of device. One commonly highlighted application is for a sensor device to capture data while away from a “hub” device for an amount of time then upload it to the hub device. The situation that is described is someone who uses a heart-rate monitor during a physical activity, especially swimming. Then, after they have completed that activity, they upload the data to their smartphone or tablet which has the fitness-tracking ap.

I also see this as being useful for updating a Bluetooth Smart device’s firmware without the need to connect the device to a computer for this purpose. This could be to add functionality to a device like a smartwatch or improve on a device’s reliability and security.

A smartphone like this one here that has Bluetooth 4.0 hardware support can head towards Bluetooth 4.1 through a software update

A smartphone like this one here that has Bluetooth 4.0 hardware support can head towards Bluetooth 4.1 through a software update

Another ability would be for a device to be both a Bluetooth Smart peripheral device and a Bluetooth Smart Ready hub device. This is obviously targeted at the smartwatches which are effectively the descendents of those 1980s-era many-function digital watches. Here, these devices could serve as an extra display for a smartphone or be a display and data-capture unit for a health monitor or another “key fob” device for the Kwikset Kevo deadbolt.

To the same extent, this functionality could allow for peer-to-peer setup with Bluetooth Smart Ready devices such as a “smartphone and tablet” or “smartphone and laptop” setup; or a quick data share setup between smartphones or tablets to work taking advantage of what Bluetooth Low Energy has to offer. This would lead to increased battery runtime for devices used in these setups.

Extra functionality has been added to the core Bluetooth 4.1 specification to support IP-based high-level data transfer especially to the IPv6 standard. This is essential for integrating Bluetooth devices in the “Internet Of Things” which is about devices beyond regular and mobile computing devices benefiting from the same kind of communication advantages that the Internet has offered.

This is becoming more important where we are seeing sensor and controller devices being part of personal health and wellbeing; and a convenient secure and energy-efficient lifestyle.

Conclusion

Bluetooth 4.1 could be a path for the Bluetooth specification to mature its role in the support of low-power devices whether they integrate with each other or with other so-called full-powered devices especially as the concept of the “Internet Of Things” matures.

The first door lock to exploit Bluetooth Smart technology

Press Release

My Comments

Kwikset have released the first door lock to exploit the nascent Bluetooth Smart technology that is part of the iPhone 4 onwards as well as an increasing number of Android and Blackberry smartphones.

Like most of these “cutting-edge” electromechanical door locks, this unit is a “bore-through” cylindrical deadbolt, most likely because this form-factor is considered very popular on the American house’s front door. From the outside, the Kevo deadbolt looks like any other lock of this type but has a distinct blue ring that lights up under certain circumstances. This, and the fact that it still works with the regular key, keeps a perceived aesthetic and useability comfort zone that householders have valued with these locks.

But the Kevo deadbolt implements a proximity-based operation technique where you have a supplied key fob or a smartphone running the Kwikset Kevo app acting as the virtual key fob releasing this lock when you are near it from the outside. This will light up the blue ring on the outside and you touch the lock’s bezel to cause the bolt to retract/

Like most, if not all. of these “smart-locks”, the Kwikset deadbolt is its own access-control system with the ability to log when a person has opened the door. It also supports time-limited and “one-shot” keys so you can limit when a person has access to the premises, which is a boon with most of us who engage tradespeople, carers or even want to have friends and family around and factor in early arrivals. This even supports the ability to allow a user to send a key via email to another user which can play its part in many different ways such as a family member or friend who is lodging at your house while they are in town.

But the Kwikset Kevo deadbolt is more or less standalone in nature and not able to work with a home network. Personally, I would like to see this and other locks of this kind support the integration with home networks and home-automation systems either at purchase or through an aftermarket kit that exposes these functions to the network technology that you are using at a later date. The reason I support the use of an aftermarket kit is the fact that these products can be in service for many many years and upgrading towards newer network functionality should avoid the need to junk a perfectly good lockset.

This is one of many trends that are affecting the residential door lock and bringing this device towards the online and mobile era.

Do you think we will end up with the smart watch on our wrists?

Why You’ll End Up Wearing A Smart Watch | Gizmodo Australia

My Comments

With the increase in smart watches being developed by various companies including Google, Apple and Samsung, there has been optimism and doubt about whether we will start wearing these watches on our wrists.

What is the smart watch?

The smart watch is an extended-function watch that works with a smartphone as a wrist-based display for the phone. These watches are in a similar vein to the 1980s-era digital watch where the more functions it had, the more you could impress others with it. In a lot of cases, these functions served many practical uses like being able to time a process or log the duration of events like races.

It would tell the time using a customisable analogue or digital display but would be able to show up notifications from your smartphone. As well as being the clock, calendar, stopwatch and timer, it could also work as a remote control for your smartphone such as navigating the music that you are playing, selecting a contact to call or text or answering a call while you hear and talk to the caller via a Bluetooth headset. Another advantage that these would offer would be the ability for us to have a discreet glance at the watch if a message comes in on our phone.

Some doubters suggested that the smartwatch wouldn’t take off because of the fact that most young people don’t wear watches anymore. Instead they use the smartphone to tell the time or, if they have to have a watch, they would wear a quartz-driven dress watch. Of course, I would expect to see the smartwatch be considered as a wearable accessory to the smartphone and can evoke a level of curiosity from other people as we wear one of these watches just like it did with the digital watch.

What I would expect of the smartwatch would be to make use of Bluetooth 4.0 and similar technologies so it can run for at least 6 months on regular watch batteries. This is in addition to having a ladies’ form factor with similar functionality but appealing for the women to wear.

As well, it should be able to keep time independently of the host smartphone device yet use that device as a master clock for setting itself when initially started and when you cross time zones or whenever we change between standard time and daylight-saving time.

Personally, I would see these watches come on the scene as a viable practical mobile accessory for our phones rather than just a fashion accessory.
