The keyboard on the palm, or a new way of controlling gadgets Bashny.Net

Scientists from the University of Tokyo presented the latest system that allows you to project controls computer devices on a moving surface.
Devices which project a keyboard image on the surface, like a table, not a novelty. In these units a sensor monitors the movement of the fingers, which allows you to enter characters by touching virtual buttons. Experts at the University of Tokyo (Japan) went on, they created a system that is able to project controls on moving objects.
The system consists of two main blocks. The first contains a projector and a special camera to track the position of an object in space at a frequency of 500 times per second. Electronics controls the operation of these modules in such a way that they always focus on the surface on which the projected picture.



The second unit, called the Airborne Ultrasound Tactile Display provides a kind of feedback (in that case, if the keyboard is projected onto the human hand). Its design includes approximately 2,000 emitters of ultrasonic waves that cause the ground to display virtual buttons on the palm tingling. It is noted that due to precise synchronization and orientation of the emitters you can create a feedback effect at any point in the volume of cubic meters.
The developers claim that their invention has already inspired a number of companies from the gaming industry, and the automotive and medical industries.
