Often times when you hear about some future tech, the tech in question is actually nothing more than an over active imagination and a lot of 3d renderings and only vaguely backed up by a working example. That is what makes this video so exciting, it is an actual working example of a future input device.
We are all faced with the problem of how as things get smaller the surface area for interacting with a device gets smaller as well. This video shows research into and actual examples of using our body as the input device for any device.
Using the principles of bone conduction, and signature resonances, you too could one day play tetris using Skinput!
