While some touchscreens seem to react when you hover your finger near it, Mitsubishi has turned this concept into something tangible with their latest tech – 3D motion tracking.

This 3D motion tracking is done with no extra cameras or sensors, and with an extremely high level of precision. So high, that it can measure your finger distance in increments of .08mm, up to a distance of 20mm, and does this action quickly enough that it can correctly guess the approach speed. It’s reported that this will most likely find its home in mobile devices, adding an extra level of interaction.

No word yet on when this will become available on a consumer level, but it has been mentioned that they’ll first use it in their own products (duh).
