Abstract: A computer-implemented method comprising receiving, at a tablet display unit of a first tablet that is coupled to a host computer, image data representing a selected portion of a common display file that is stored on an administrator computer; displaying the image data on a stroke-sensitive display of the tablet display unit; receiving user input from the stroke-sensitive display of the tablet display unit and representing handwritten strokes; transmitting the user input to the administrator computer; receiving, from the administrator computer, second image data representing strokes that other users have applied to the same image data using other tablets that are coupled to the administrator computer over a network; displaying, on the stroke-sensitive display, the second image data; storing, in a memory of the tablet display unit, a data file based at least upon the user input and the image data.

Abstract: In an embodiment, a computer-implemented method comprises receiving, at a tablet computer that is coupled to a host computer, image data representing a selected portion of an electronic document; the tablet computer displaying the same image data on a stroke-sensitive display of the tablet computer; the tablet computer receiving user input from the stroke-sensitive display and representing handwritten strokes; the tablet computer storing, in a memory of the tablet computer, a data file based at least upon the user input and the image data; transmitting the stroke data from the tablet display unit to the coupled host computer where the stroke data appears on the original image data.

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.
