Ultra-Sound Device, feel shapes in Mid Air

This is cool, researchers at the University of Tokyo have demonstrated a device that can create touchable, creepily invisible floating "objects" using focused ultrasound waves.

Imagine feeling your baby while still inside your womb, well this is the first step in creating such technollogy.

For now, the team has only been able to simulate resistance in one direction, but say that forming complex shapes and textures is plausible.

Sadly at this point there's a major catch, though: the virtual objects won't provide much resistance or seem very "hard," because at high enough levels the aurally imperceptible ultrasound will destroy your eardrums.
