Closed loop application of electroadhesion for increased precision in texture rendering
Roman V. Grigorii, J. Edward Colgate
Tactile displays based on friction modulation offer wide-bandwidth forces rendered directly on the fingertip. However, due to a number of touch conditions (e.g., normal force, skin…
