Despite recent advances in technology for upper-limb prostheses, artificial arms and hands are still unable to provide users with sensory feedback. DARPA has awarded prime contracts for Phase 1 of its Hand Proprioception and Touch Interfaces (HAPTIX) program.

HAPTIX seeks to create a prosthetic hand system that moves and provides sensation like a natural hand. Sensory feedback, especially from the hand, is vitally important for many functions, and HAPTIX seeks to create a sensory experience so rich and vibrant that users would want to wear their prostheses full time.
