A touch device includes a substrate, multiple first electrodes, multiple second electrodes, multiple third electrodes, and a control circuit. The control circuit senses a touch position based on a first signal from the first electrodes. The control circuit transmits a second signal to the second electrodes based on the touch position, such that the second electrodes provide a first haptic feedback which is parallel to a top surface of the substrate. The control circuit also transmits a third signal to the third electrodes based on the touch position, such that the third electrodes provide a second haptic feedback along with a normal vector of the top surface of the substrate.
