OmniTouch: Wearable Multitouch Interaction Everywhere

Researchers at Microsoft and Carnegie Mellon University created a prototype called OmiTouch that enables graphical, interactive, multitouch input on arbitrary, everyday surfaces.

According to the paper, The shoulder-worn implementation allows users to manipulate interfaces projected onto the environment (e.g., walls, tables), held objects (e.g.,notepads, books), and their own bodies (e.g., hands, lap). A key contribution is our depth-driven template matching and clustering approach to multitouch finger tracking. This enables on-the-go interactive capabilities, with no calibration, training or instrumentation of the environment or the user,

According to the paper, it is entirely possible that a future incarnation of OmniTouch could be the size of a box of matches, worn as pendent or watch. Thus, the benefit of extreme portability.

An ECG for the iPhone

The future of medicine is changing rapidly with the emergence of mobile computing. A system developed by AliveCor that converts the iPhone or iPad into a clinical quality electrocardiograph (ECG) device. The system involves an application that can work with any iPhone or iPad and a card with electrodes (iCard) that is smaller than a business card which sticks to the back of the iPhone or iPad. 

 The company claims that the iphone ECG system gives an accurate clean clinical quality electrocardiograph. According to the company, the iphone ECG records and uploads the reading onto a server and converts into a pdf file for analysis by a medical professional within five seconds.
