Abstract:
A multilayer input/output device with a low power and a high resolution display suitable for use in paper-like computing includes a first display layer, a second display layer, an input layer and control logic. The first display layer is a low power display. The second display layer is a fast, transparent display positioned on top of the first layer. The input layer is a layer for detecting input movements or gestures by the user. The control logic is coupled to the first display layer, the second display layer and the input layer for controlling their operation according the method of the present invention. The method of the present invention selectively operates the second display layer to present movement detected by the input layer. At a predetermined time, the information presented on the second display is transferred to and presented on the first display.
