The Omnittouch system makes paper sheets an interactive surface

A portable projector system allows users to make paper, wall or even human hands into a graphical interface that can interact.

The technology, called "Omnitouch" , was developed by researchers at Microsoft Research and Carnegie Mellon University, USA. It is based on a touch screen camcorder (similar to the Microsoft Kinect system) to track the movement of the user's fingers on interactive surfaces.

This technology allows users to control interactive applications by typing or dragging the fingers, which are touch screen operations found on smartphones or tablets.

Omnitouch projectors have the ability to integrate: keyboards, small keyboards and other controls into any surface, automatically adjusting to the shape of the surface and orientation to minimize distortion. the images are projected.

You can imagine that anything that you can manipulate on today's mobile devices, you can also manipulate the same on your own hands using the Omnitouch projector system, According to Chris Harrison, PhD student at the Institute of Human-Computer Interaction, Carnegie Mellon University, USA.

Developers claim that the palm of a hand can be used as a telephone keypad, or as a small graphic tablet to write short notes. In addition, the map on a wall can be zoomed or zoomed in finger movements (just like you are working with a conventional multi-touch screen).

The Omnitouch projector system includes: a short-range camcorder, pico projector using a laser, and placed on the user's shoulder. However, Harrison says the final device may be the size of a deck of cards, or even a matchbox, so it can easily slip into the pocket (jacket, pants), or be integrated into it. the future handset.

With the Omnitouch projector system, we want to take advantage of the enormous surface area provided by the real world, says Hrvoje Benko, a research fellow in the Microsoft Research Interactive and Adaptation team.
