Abstract

A detachable wireless presentation device is provided, which not only functioned as a touchpad of a presentation playing apparatus but also allows user to operate the presentation playing apparatus in a wireless remote manner. The presentation device comprises left and right buttons replacing the original function of a mouse, last/next page control buttons, a laser pointer button and a touch-control interface. When the user wishes to deliver a presentation by projecting output image from the presentation playing apparatus to a display screen via a projector, presentation progress involving such as changing a presented page or indicating the position of the currently presented content, can be directly carried out in a wireless manner by operating the presentation playing apparatus via the presentation device. Thereby the projecting image of the presentation playing apparatus can be changed immediately in accordance with the presentation flow and thus enhances efficiency and effectiveness for delivering the presentation.
