Introducing touchscreen that works inside your pockets

- Tuesday, 14 February 2012 No Comments

Researchers have developed a prototype for a touchscreen that can allow its users to send text messages even when it is kept inside a jacket or pants pocket.The stealthy screen works when it is touched through the fabric, whether it is silk, cotton or even thick fleece, the Sydney Morning Herald reported. In classes or meetings of the future, with your hands tucked underneath the conference table or desk, the user may rest a fingertip tactfully on the pocket that holds the touch screen and handle a call by tracing a message like “Running late. In a mtg.” on the fabric above the hidden screen.

The touch screen will comprehend the message - it has a program to decode handwriting, even of the scrawling sort. So even while a person is writing on his pocket, he can maintain polite eye contact with the group, no longer betrayed by those telltale downward gazes necessary to text with a standard screen.
The technology, called PocketTouch, is the brainchild of Microsoft researchers Scott Saponas and Hrvoje Benko with Chris Harrison, a PhD student at Carnegie Mellon University in Pittsburgh, Pennsylvania. The prototype uses sensors similar to those used in most touch screens, and is mounted on the back of a smartphone case.
“There are a lot of situations where this technology could be useful,” said Jeffrey Bigham, an assistant professor in the computer science department at the University of Rochester, who chaired a conference panel on computer user interfaces where PocketTouch was demonstrated. “It’s a way to send short messages when it is not socially appropriate to fish out your device,” he said, or in many other instances when people simply don''t want to go to the trouble of removing a device from a pocket.
“Most touch screens are calibrated in a static way, only responding to direct touch with a finger, and rejecting a slightly different signal,” Benko added. On the contrary, PocketTouch calibrates continuously, adapting to different kinds of fabrics.

The Multi-touch surface computing

These coffee table-sized devices have been appearing in business venues for a couple of years already. They are now becoming cheap enough for the consumer market.
This computing platform responds to natural hand gestures and real world physical objects. It has a 360-degree user interface and a large reflective surface, with projectors underneath which project images onto its underside. Cameras in the machine's housing record reflections of infrared light from objects and fingertip movements.



The surface is capable of object recognition, object/finger orientation recognition and tracking, and is multi-touch and is multi-user. Users can interact with the machine by touching or dragging their fingertips and objects such as paintbrushes across the screen, or by placing and moving placed objects. The platform can respond to over 50 touches at a time.
The use of multi-touch technology is increasing exponentially during this time. For example, sales of touchscreen phones will rise from 200,000 in 2006 to over 21 million by 2012, while iPads and other tablet devices are seeing similar growth.
