From: A learning-based approach to artificial sensory feedback leads to optimal integration
Animals sit in a virtual reality environment without direct view of the arm. A mirror reflects images on rear–project screen and is adjusted so that visual cues appear in the horizontal plane of the reaching hand. Hand position was tracked electromagnetically (Polhemus Liberty, Colchester, VT), and feedback about the position of the hand, relative to the target, was delivered via a random–dot visual flow field (inset) or via patterned ICMS.
