Haptic Radar Cap

The University of Tokyo's Ishikawa Komuro Laboratory is developing a wearable
and modular device allowing users to perceive and respond to spatial
information using haptic cues in an intuitive and unobstrusive way. The
system is composed of an array of "optical-hair modules", each of which

cue on the skin directly beneath it. Among the targeted applications of this
interface are visual prosthetics for the blind.
