Idea: Vibration dependant on distance measuring

[Ole Tange]

Blind people need navigational aid. Today devices exist that vibrate
according to the distance from the device: If the distance is long it
hardly vibrates. If the distance is short it vibrates violently.

If Neo can measure distances using ultrasound and has a controllable
vibrating feature it should be possible to emulate this device with
the Neo.
