Abstract
A haptic drive circuit for an electrical muscle stimulation electrode has an input for receiving a haptic signal based on a haptic effect from a haptic effects processor. The drive circuit contains logic for generating a electrical muscle stimulation current based on the haptic signal. An electrode in contact with a user's skin receives the electrical muscle stimulation current, causing a haptic effect by contraction and relaxation of muscles near the electrode.
