Pressure-Sensitive Bluetooth 4.0 Stylus Coming to iPad#xtor=RSS-181#xtor=RSS-181#xtor=RSS-181#xtor=RSS-181

My Comments

The Bluetooth 4.0 Smart Ready ability that the Apple iPad has now is being considered of use. Here, Ten One Design have introduced a pressure-sensitive stylus that works with this touchscreen tablet and turns it in to a digitizer. This has the ability to increase the thickness and darkness of a line as you add pressure to the stylus in a similar vein to the real pen or pencil

Six of the iOS drawing apps provide inherent support for this stylus with more on the way. Here, the developers would have to integrate the functionality for this device in their software to have it work. As well, it would require you to work with the files being held on your iPad.

But, with appropriate bridging apps for the iOS platform and the MacOS X and Windows regular computing platforms, this could make it feasible for an iPad that is tethered to a regular computer to become an improved version of one of those “digitizers” or “graphics tablets”. These devices had a tablet surface and a stylus so you could trace hand-drawn graphics or do freehand drawing in to a graphics program. In some cases, these tablets also were a command surface for some CAD programs where you entered drawing commands by “picking” them using the stylus.

Here, the combination of an always-updatable touchscreen display could allow for a variety of options for this class of work. For example, it could permit the direct edit of work on the iPad while using the main screen as an overview display. This could include freehand digitizing and drawing with the iPad providing a natural “paper” feedback and the work appearing on the graphics program.

Similarly, a CAD / CAM program could benefit from turning the iPad in to a “tabbed” command tablet with the stylus being used to “pick” the commands.

Here, the idea of a Bluetooth stylus or, in some cases, a “puck” could make the iOS or Android tablet earn its keep in the CAD or graphics-design office rather than just as a tool for media consumption.

Internet-based health care–now a reality

My Comments

The home network and the Internet is now becoming an essential part of personal health care in may ways thanks to a variety of technologies.

Facilitation technologies

Level playing field for health-care sensor devices

Certain technologies are making this feasible through the use of device classes for health-specific devices such as blood-pressure / pulse cuffs, blood sugar monitors and heart-rate monitors. They are also being enabled with low-voltage wireless technologies like Bluetooth Smart and up-and-coming low-voltage Wi-Fi designs.

These devices are being made able to work from two AA batteries or a 3V watch battery for a long time, yet use an industry-common data link and device class. The actual benefit from these design factors is the ability to supply health-care sensor devices that are cost-effective to buy and maintain; yet are able to integrate with common computing devices.

Ubiquity of open computing platforms for this application

It is being extended with the availability of regular, mobile and TV-based computing platforms like Windows, MacOS X, iOS and Android as foundations for software that records and / or reports medical-status information.

The software can be designed to keep a local or cloud-based record and signal to health-carers and/or close relatives and friends if there are abnormal events. In some cases, details can be passed through immediately to the health-care professional who is supervising the patient.

Where do I see this being applicable

I see this technology being applicable for the management of chronic illnesses where the patient can manage the illness themselves with little outside intervention. This may extend to the care of pregnant women who have a low risk of birth complications. Even when the patient must travel to the health-care professional for an appointment, both the professional and the patient are in a better position to know “what’s going on” through the treatment process.

It also adds a sense of dignity to the care and treatment process by allowing one to integrate the management procedures in to their lifestyle without feeling awkward about it. This would benefit younger and middle aged people more so especially when they are encumbered with these illnesses like diabetes.

I see it also benefiting people living in rural areas in many ways. The telehealth technology can allow a specialist based at a small or larger town to manage multiple patients and only have to travel out to attend those at risk. As well, the patient wouldn’t need to travel out to the doctor unless necessary.

It can also assist with the ageing process for seniors who want to live in their own home, live in an “own space” near their relatives such as a granny flat or live in low-needs supported retirement accommodation. Here, the technology can help with supervising medical and other therapies or simply make sure they are OK without intruding on their lifestyle and dignity. In this case, it could augment other technology projects that are in progress or being completed that assist older people with their daily lives.

Similarly, the technology would help with sports medicine in allowing athletes and fitness enthusiasts, along with their trainers, know their limits and how they are performing through their workouts so they can exercise in an optimum way.

Conclusion

I would still like to see the telehealth technologies work as a complement to the personal touch in personal health care rather than distance the patient from the professional. The technologies can be seen as a tool for helping us stay well and independent; as well as conquer distance.

Bluetooth Smart–What does it mean for Bluetooth devices

Article – from the horse’s mouth

Bluetooth SIG – "Bluetooth Smart"

My Comments

Bluetooth 4.0 Low Power technology, formerly known as Wibree technology has been put on the market this year. This technology is pitched more for “sensor/controller” devices that primarily provide data to another device; and are required to run for a long time on two AA batteries or a “button-style” battery. Examples of these devices include watches, heart-rate monitors, shoe-attached pedometers, door-window security sensors and the like.

These devices are being marketed as Bluetooth Smart devices and Bluetooth terminals like smartphones and computers that can work with these devices are marketed as Bluetooth Smart Ready devices.

A Bluetooth Smart device like the heart-rate monitor or door security sensor has to be compliant to Bluetooth 4.0 Low Power as a single-mode device and support GATT functionality. These devices cannot work with legacy Bluetooth devices that don’t support this standard.

Bluetooth Smart Ready is used to describe a Bluetooth device, typically a “hub” device like a computer or smartphone that works with these Bluetooth Smart devices. The Bluetooth Smart Ready device must have Bluetooth 4.0 enablement with GATT support. It also has to have a dual-mode low-energy Bluetooth transceiver and updatable software. This would typically benefit regular and mobile/embedded computing devices that work to a “platform” like Windows, MacOS X, iOS or Android. These devices can connect to the Bluetooth Smart devices as well as regular Bluetooth devices.

At the moment Apple has the Smart Ready devices  in the form of the iPhone 4S and the latest iterations of the MacBook AIr and Mac Mini computers. But this technology will be rolled out in to newer computers and Bluetooth modules. The Bluetooth Smart technology will be a point of innovation as companies develop the sensor devices and software for this newer hardware platform.

I would also see this as an improvement for Bluetooth keyboards, mice and controllers due to the idea of having these devices run on a pair of AA batteries that assure reliable operation for a long time without needing to be charged frequently.

It will open up the Bluetooth universe to a larger collection of devices, services and applications that most of us wouldn’t have thought of.
