Description of Invention

The presentation device of the invention comprises a body (1) having a multi-touch screen (2) arranged at front side thereof. The screen (2) may have its "multi-touch screen" functionality by a frame (3) having an LCD screen to be adaptable to a computer (11) of the device externally, or the screen (2) can be directly adapted to the presentation device. The multi-touch screen (2) has a number of light emitting diodes (LED) arranged vertically and horizontally through the edge portions of the screen (2) and the precise coordinates of the contact by a touch on the screen can be identified via interrupting lights of the LEDs where the contact takes places. Any presentation material, including images, editable or non-editable text materials, portable documentation files, sound or video files may be modified, intervened, copied, pasted deleted etc. by touching the respective points/locations on the screen (2). A scanner (4) and a printer (18) are directly connected to the device, in particular to the front side of the multi-touch screen (2) so that the printed material can be instantly converted into a digital medium, and which may be further modified via the multi-touch screen (2).

A finger print reader (5) communicating with the computer (11) and run by a software to identify pre-defined finger prints is arranged on the device so that the device can be switched on by only authorized individuals.
