The present invention includes an inclination sensor detection device for detecting the inclination of the terminal, the movement of the sensor to detect the inclination according to the inclination of the terminal up / down / right to control the operation of the pointer, such as an input device of the display panel It relates to a communication terminal.

The user interface provided by the general mobile communication terminal is designed to be more convenient and easier to use. In the early mobile communication terminal, the basic keypad was centered, and voice service was the most important role. Therefore, the various function keys were not needed.

For this reason, the user interface of the early mobile communication terminal was proportional to the size of the mobile terminal and there was only a simple number and a few letters on the visible keypad. It was no different from the interface.

Users would not feel at all unfamiliar with the transition to the same structure as the interface on the landline phone they were using, and these interfaces were well designed and arranged to conveniently perform the basic functions of early voice calls.

In the beginning of the voice service, the user interface of the terminal changed due to the desire and demand for miniaturization of the mobile communication terminal with the increase of additional services. Characters were used in common, and the diversification of personal information management required a function key of various functions.

However, due to the space constraints caused by the miniaturization of the conventional mobile communication terminal, it is difficult to add buttons, and as a result, existing keypads have been used in various combinations, and these combinations have become increasingly burdensome to the user. As a result, it was inconvenient to read the manual for a long time when purchasing a new model terminal.

An operation operation related to a user interface of a conventional mobile communication terminal will be briefly described as follows.

First, when the user presses the power switch to turn on the power of the terminal, the power supply unit supplies the necessary power to each component, and when the normal power is formed, the date and time are displayed on the screen. And make it appear in a callable form.

When the user presses the number desired for the call for the voice call and finally presses the call button, the user calls the base station so that the call is connected to the terminal corresponding to the number to enable the voice call.

The user presses a menu button to manage personal information. At this time, a user uses a combination of direction keys and numeric keys to move to a corresponding menu, and when pressing or changing personal information, another key must be selected at this time.

To use the current Internet service, select the direction key several times to move to the corresponding position when selecting the corresponding sub menu, or press the desired number, or press the soft key to move forward or backward. Another way is to move through the menu.

As described above, the user interface operation of the conventional mobile communication terminal inevitably requires the selection of an image and a link appearing in a web document and the use of multiple keypads when the page is moved when using the Internet service provided by the current terminal. There is a problem that inconveniences the user in using the user interface.                         

In addition to the above, thanks to the rapid development of the mobile communication field and the development of mobile communication terminals, it is possible to search data and perform work using the Internet through the terminal.

Since the menu navigation using the keypad is not suitable for the window system in the arrangement of the icons or the menu selection, an input device that functions as a mouse of a computer is required for the portable terminal to perform the above functions. The touch screen that sends an input signal by applying pressure to the track and the track ball that moves the cursor on the screen by moving the round ball and the distance are used.

However, the touch screen has a problem in that it is difficult to input fine pointing and it is difficult to apply the trackball mouse to a terminal which is gradually miniaturized.

Therefore, the present invention has been proposed to solve the above-mentioned conventional problems,
