VibraVest / ThinkTank

VibraVest / ThinkTank is a computational tank top that is worn, in close contact to the body, under ordinary clothing, to afford a synthetic synesthesia of a new sensory modality, namely radar, which gets translated to "feel". The chirplet transform, and other DSP methodology may detect targets accelerating toward the wearer, helping him or her avoid bumping into things, and similarly make the wearer blind to targets that are moving away, solving the "information overload" problem.
