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 configured for selection of a pen-table function to be performed by another electronic device in communication therewith, said portable electronic apparatus comprising:

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

a mobile communication module for implementing a voice call based on a mobile communication protocol;

a controller for controlling the operations of the touch-screen module, the local area communication module, the mobile communication module and the display module and for transmitting position data created by the touch-screen module to said another electronic device that includes functions of a pen-table and local area communication in response to a user'"'"'s selection of the pen-table function via the touch screen module; and

wherein said portable electronic apparatus provides input of pen-table data and operational control of the pen-table function performed by said another electronic device through the touch screen module, local area communication module, and controller.

2. The portable electronic apparatus according to claim 1, wherein the mobile communication module implements a video call based on the mobile communication protocol.

3. The portable electronic apparatus according to claim 1, wherein in response to the 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 the touch screen to the electronic device.

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

a first electronic apparatus and a second electronic apparatus,

the first electronic apparatus including a touch-screen module for detecting contact with an external object upon a region of a touch screen and creating position data of the detected region, a first local area communication module transmitting and receiving data based on a local area communication protocol, a first display module for displaying the detected region and information on a user interface (UI) and functions supported by the apparatus, a mobile communication module for implementing a voice call based on a mobile communication protocol, a first memory for storing an operating system (OS) and data for driving the UI, and a first controller for controlling the operations of the touch-screen module, the local area communication module, the mobile communication module and the display module and transmitting position data created by the touch-screen module to an electronic device that includes functions of a pen-table and local area communication in response to the user'"'"'s selection of the pen-table function,

the second electronic apparatus including a second local area communication module for transmitting and receiving data based on the local area communication protocol and for receiving the position data created by the touch-screen module, a second memory for storing an OS and data for driving a UI, a second display module for displaying a requested OS and information, and a second controller for controlling the operations of the functioning units in response to user'"'"'s input and for displaying the position data via the second display module;

wherein said first electronic apparatus provides input of pen-table data and operational control of the pen-table function performed by said second electronic device through the touch screen module, local area communication module, and controller.

5. The computer system according to claim 4, wherein the mobile communication apparatus in the first electronic apparatus implements a video call based on the mobile communication protocol.

6. The computer system according to claim 4, wherein in response to a pen-table function selection within the first apparatus, the first controller controls the operations of the touch-screen module and the local area communication module so as to transmit the position data detected by the touch screen to the electronic device that includes the functions of the pen-table and local area communication.

7. The computer system according to claim 4, wherein the first electronic apparatus comprises one of a mobile communication terminal, a portable multimedia player (PMP), a MP3 player, and a portable navigation terminal.

8. The computer system according to claim 7, wherein the second electronic apparatus comprises a desktop computer or a laptop computer.

9. The computer system according to claim 7, further comprising a digital baseband and application processor (DBAP) for processing input, preparing display data, and executing a software program providing modes based on functions of the mobile communication terminal.

10. The computer system according to claim 9, further comprising an analog baseband controller (ABC) coupled to the DBAP, for processing data from cellular phone signals or data for cellular phone signals in order to implement a function of a portable phone.

11. The computer system according to claim 4, wherein the second controller creates, on a region corresponding to the position data of the detected region of the touch screen of the first electronic apparatus, data for indicating a mouse pointer, and then provides it to a video output.
