IO2 'M2i touch-sensitive heliodisplay'

IO2 Technology is set to redefine the way we see things on screens with its latest 'M2i' holographic display technology. The M2i heliodisplay projector delivers 'free-space' image with a maximum 30" diagonal and 4:3 aspect ratio. Moreover, the floating image is touch-sensitive giving an enigmatic and enticing experience to the viewers.

According to IO2, the M2i, just like M2, is not holographic display; rather they're pitching it as:

Heliodisplay images are not holographic although they are free-space, employing a rear projection system in which images are captured onto a nearly invisible plane of transformed air.
