Claim Text:
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, wherein the first haptic effect is in response to a virtual contact with a user interface, and the virtual contact is without physical contact with the user interface; 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 adapted to contact with a user's skin, and wherein the first current is transmitted to the first electrode, the first current causing the first haptic effect to be generated by contraction and relaxation of muscles near the first electrode; wherein the contraction and relaxation of muscles simulates physical contact with the user interface.
