Designed for the Paralympics, Ghost fits on your arm. It consists of several pieces, including two which provide haptic feedback based on computer output.
Here's the rationale:
[V]isually impared or indeed blind athletes having trouble with their kinesthetic movements, basically locating their limbs in space. Currently the only real way to ovecome this is to practice sporting technique, whether it be a swimming stroke, tennis stroke or archery with a personal trainer learning the movement through rote memorisation until becomes part of their muscle memory...
Through continuous ideation and fast prototypes we identified that it was possible to guide the body with extreme accuracy using haptic (vibration) based feedback, bypassing the need for full vision.
Imagine the uses beyond this group. And imagine the possible fearsome implications.
