Wearable User Interface

Based on the augmented reality, Wearable User Interface refers to the wearable computing providing the miniature and purpose specific electronic devices to be carried out with, under or top of the clothing. Multitasking and consistency are the two crucial aspects of these devices that offers parallel execution of multiple tasks without interrupting the core functionality. Before wearable computing, augmented reality is just prototyped and simulated but with the advent of wearable user interfaces miniature sensory and computational devices are practically built (e.g Witt, H. (2007), Nicolai, T., Sindt, T., Witt, H., Reimerdes, J. (2006) and Clark, A.F., Newman, N., Isaakidis, A., Pagonis, J. (2003)).

Marianne (2012) elaborated some of the wearable user interface based sensors, monitors and devices in healthcare, which are IntelliVue MX40, BlueLibris, BioHarness BT, BodyMedia’s patch, Zoll LifeVest – defibrillator monitors, B1 wrist band and Nike Fuel Band. Functional details of these medical wearables in terms of their general collaboration among each other and communication with the doctor based station are as follows:

IntelliVue MX40 is the smart version of integrated medical gears, pumps and monitors, by putting a compact Patient Monitor that provides with the functionality of monitoring patients during transport and ambulatory patients. BlueLibris is a gateway technology assisting the patients to upload the biometric measurements so that to receive the reminders accordingly. BioHarness BT can monitor the measures related to blood oxygen, ECG and blood pressure. BodyMedia’s patch is used as an evaluation tool that aims at measuring the weight and monitoring the metrics like sleep patterns, activity levels, steps taken and calories burned. Zoll LifeVest monitors the heart patients by using wearable defibrillator monitors and to detect the sudden cardiac arrest related risks. An automated shock is delivered to restore normal heart beat if any heart threat is detected. A multi-sensor band called B1 wristband links the personal details of the bearer to the Web based Dashboard that helps in engaging with other users, sharing data and viewing the bearer’s performance. Four metrics are displayed and captured by Nike FuelBand. Steps, Calories and time are the first three basic metrics and the fourth metric is NikeFuel, introduced by Nike for measuring the physical activity of the user.

Wearable miniature electronic devices require a management information system that include intra- and inter- data management to monitor and control the related medical measurements in order to apply proactive health measures. Relating to different component based monitoring and evaluation of the wearable user interfaces, MIS requires alarms for abnormal behavior detection and to depict the risk measure of the specific body metric like blood pressure and ECG, while keeping in comparison the medical history of the bearer. When designed efficiently, wearable devices offers promising monitoring and control of body metrics.

MIS for wearable computing is complemented by the sciences of Human Computer Interaction (HCI), Usability Engineering, Artificial Intelligence, Machine Learning and Neural Networks. Device and Graphical User Interface (GUI) are the two major components of the wearable computing. Device should be designed keeping in consideration the usage for a layman with no prior training and technical knowledge of the computational sciences. GUI is to kept handy for the doctor and other related management staff in terms of quick access to components for more often use. Access Management System (AMS) of the MIS should be defined in a way that the privileged access of patient’s disease and health state is accessed only by the concerned authorities in order to retain the confidence of the bearer on the device.

New Nexus smartphone due and people are standing in waiting queue

Got one fantastic device, now waiting for another one with more astonishing features? Yes, it’s natural. Same happens with the Samsung users. Last year Google released its Nexus smartphone that is Samsung Galaxy Nexus GT-i9250. Since then rumors were subsiding for New Nexus smartphone but Alas rumors are still rumors and people are desperately standing in the queue to have the first sight of that unseen. Numbers of possibilities are depicted in the rumors, and the most convincing one was that the Samsung is launching follow up version with much extensions named Galaxy Nexus 2, let’s see who will win the award of making most accurate picture of the unseen.

New Nexus smartphone is due since the release of Galaxy Nexus GT-i9250. Something about the naming conventions of Samsung smartphones and tablets is here to build a name for New Nexus smartphone. Model numbers are used in Samsung sets instead of code-names for their tablets and smartphones. The existing Galaxy Nexus was GT-i9250, though latest devices like the Galaxy S (i9000), SII (i9100), and SIII (i9300) are following the same manner in their naming criteria.
A device – New Nexus smartphone – with the code Samsung GT-i9260 has appeared in some EXIF data photos, supporting its conventions to be the follower of earlier updates being i9250, i9000, i9100 and i9300. Fresh rumors have more refined research as per the features listing of New Nexus smartphone. Rumors suggested the New Nexus smartphone would astound the very 4.65-inch HD Great AMOLED display screen, but with an improved camera will get an increase in all the dimensions, twice over the RAM to 2GB, increasing battery capacity and finally the vital part of it, yes it’s faster dual or quad-core processor. Isn’t it sound to be too generic set of features? But the potential benefit of such a generic guess is that the person will never lose a bet. Well, interesting it is. It’s good to enjoy ridiculous pile of rumors, speculation and leaks in the way to see the final – New Nexus smartphone.
New Nexus smartphone haven’t received any solid technical words from the officials about its specifications and naming confirmation but people are curious enough that some desperate souls have leaked the specification sheet and camera details of New Nexus smartphone for his or her other awaiting fellows. Confusions are there on the exact name of the New Nexus smartphone and some reports in the Journal of Wall Street suggest that most probably there is a series or a bunch of many New Nexus smartphones in this year and the year is about to end soon.
And it’s October. The same month that brings Galaxy Nexus GT-i9250 last year. Stay tune, there is much more good to come about New Nexus smartphones!
