DisplAir is a projector that projects your screen in Air and the best part is the screen is also interactive, which means we can play with the screen in Air. That’s cool right.
Displair is able to capture hand movements allowing for virtual object manipulation in free space. The “basis” of the image is created inside of aerodynamic layer of dry fog which is composed of ultra-fine water droplets. 3-dimensional interactivity is made possible by aid of IR sensors and camera registration.
