The
OmniTouch, a wearable device created by researchers at Microsoft and
Carnegie Mellon University, can transform a hand, sheet of paper or
table into a multi-touch, iPad-style interface.
Mounted on a shoulder, the OmniTouch
can project such images as a typewriter keyboard, a blank notepad or a
map, each tailored to the chosen surface. A depth-sensing camera looks
for cylindrical objects (that is, fingers) and reports to a desktop
computer whether they're hovering, tapping, drawing or "pinching" the
virtual screen. Somewhat cumbersome now, the system is designed for a
future in which we look back on 4-inch smart-phone screens as hopelessly
confining.
