Abstract
The present invention provides a localization and haptic feedback system based on time-reversal signal processing for touch panel. Firstly, the panel model and impulse responses of an elastic panel are established according to the plate theory, and then a mathematical model is established according to the impulse responses and the time-reversal signal processing (TR). When an impact force hits the elastic panel, the touch point on the elastic panel generates a touch signal, and then received by at least a sensor at the corner of the elastic panel. The touch signal is converted into a time-reversal signal according to the mathematical model by a simulator. The time-reversal signal is reversed to the touch point for simulating reversal vibration waves of the time-reversal signal on the elastic panel, and located the location of the touch point.
