Abstract
Disclosed are a method and corresponding touch sensitive device that detects touch and provides tactile feedback. In an embodiment, the device includes a touch interface having row conductors and column conductors. A first row signal generator transmits a first row signal on a first row conductor. A second row signal generator transmits a second row signal on a second row conductor, the second row signal being orthogonal to the first row signal. A third row signal generator generates an electrotactile discharge signal on at least one of the row conductors. In an embodiment, the electrotactile discharge signal is time multiplexed with at least one of said first row signal or said second row signal. A touch processor identifies a touch event on the touch interface by processing signals present on at least one of the column conductors.
