ELECTRICAL STIMULATION HAPTIC FEEDBACK INTERFACE

摘要

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.

主权项

1. A drive circuit for an electrode, the drive circuit comprising:
an input for receiving a first haptic signal, wherein the first haptic signal is based on a first haptic effect determined by a processor; logic for generating a first current based on the haptic signal; and a first electrode for receiving and relaying the first current, wherein the first electrode is in contact with a user's skin, and wherein the first current is transmitted to the first electrode, the first current causing a haptic effect to be generated by contraction and relaxation of muscles near the first electrode.
