7 is a diagram illustrating a method of automatically switching the right / left user mode of the tablet 100 according to the present invention. In the automatic switching method shown in Fig. 7, the approach of the user's body is detected through the proximity sensors 112a and 112b, and the mutual switching between the right-handed user mode and the left-handed user's mode is automatically performed according to the detection result. When the user generates an external input for selecting activation of the proximity sensors 112a and 112b via the configuration menu, the controller 402 of the tablet 100 responds to the external input (i.e., selection) ) 112b (702). The two activated proximity sensors 102a and 102b detect 704 whether the user's body (e.g., the left or right hand) is approaching. The control unit 402 sets the right-handed user mode or left-handed user mode according to the detection results of the proximity sensors 102a and 102b. If the tablet 100 of FIG. 1 detects the approach of the user's body (e.g., the left hand) to the left proximity sensor 102a, the controller 402 determines that the user's left hand approaches the left side of the tablet 100, (See FIG. 5), and the user interface 104 is displayed on the left side of the display area of the display 102 by switching the tablet 100 to the right-handed user mode. Conversely, when the user's body (for example, right hand) is detected by the right proximity sensor 102b of the tablet 100 of FIG. 1, the control unit 402 determines whether the user's right hand approaches the right side of the tablet 100, Based input to the tablet 100 is performed and the operation mode of the tablet 100 is switched to the left-handed user mode so that the user interface 104 is displayed on the right of the display area of the display 102 (708) Reference). Such mutual switching of the operation modes is automatically performed according to which of the two proximity sensors 102a and 102b the human body approach is detected.

12 is a diagram illustrating a color setting process using the color setting menu button 1104e. A sample color display method for color setting includes a color wheel display method (FIG. 12A) and a honeycomb display method (FIG. 1B). In the color wheel display method, as shown in Fig. 12 (A), various colors are displayed in a continuous band shape to enable precise color selection. In the honeycomb display system, as shown in Fig. 12B, a desired color can be conveniently selected by displaying predetermined standard hues in a honeycomb structure composed of cells of a certain size. In addition to the honeycomb method, a cell may be formed of a different shape (for example, a square or a circle) to display a color. 12 (A), the color setting menu button 1104e is switched to a honeycomb shape. When the user touches the honeycomb-shaped color setting menu button 1104e, The same honeycomb display mode is switched. 12B, the color setting menu button 1104e is changed to a color wheel shape. When the color setting menu button 1104e is touched, the color setting menu button 1104e is displayed. As shown in FIG. A color wheel display system as shown in FIG. 12 (A) allows precise color selection, but is somewhat inconvenient for repeatedly selecting the same color. This is because the color selected by the fine positional change in the color wheel may also vary slightly. Instead of the honeycomb display system shown in Fig. 12B, only a predetermined color can be selected, and the degree of freedom of color selection is relatively reduced.
