Abstract

A portable electronic apparatus functioning as a pen-table, includes a touch-screen module for detecting contact with an external object and creating position data of a detected region. The portable electronic apparatus, by functioning as a pen-table, eliminates the need to install or carry a mouse, a pen-table, etc. for controlling a personal computer, a laptop computer or the like. A local area communication module transmits and receives data based on a local area communication protocol, and a display module displays the detected region and information on a user interface (UI) and functions of the apparatus. A controller controls the operations of the modules in response to the user'"'"'s input so as to transmit position data created by the touch-screen module to an electronic device that includes the functions of a pen-table and local area communication.

Claims

1. A portable electronic apparatus including a pen-table, function, said apparatus comprising:

a touch-screen module for detecting contact of an external object and creating position data of a detected region;

a local area communication module for transmitting and receiving data based on a local area communication protocol;

a display module for displaying the detected region and information on a user interface (UI) and for displaying functions supported by the apparatus; and

a controller for controlling the operations of the touch-screen module, the local area communication module, and the display module in response to the user'"'"'s input and for transmitting position data created by the touch-screen module to an electronic device that includes functions of a pen-table and local area communication.

2. The portable electronic apparatus according to claim 1, further comprising a mobile communication module for implementing a voice call based on a mobile communication protocol.

3. The portable electronic apparatus according to claim 1, further comprising a mobile communication module for implementing a video call based on a mobile communication protocol.

4. The portable electronic apparatus according to claim 2, wherein in response to a pen-table function selection, the controller controls the operation of the touch-screen module and the local area communication module to transmit the position data detected by a touch screen of the touch screen module to an electronic device that includes functions of a pen-table and local area communication.

5. A computer system using a pen-table comprising:
