Referring to FIG. 5, the method for displaying a touch screen keyboard in the device according to the present embodiment includes the following steps.

In operation 501, the input detector detects a predetermined input as described with reference to the embodiments of FIGS. 2 and 3. Assuming that the user looks at the screen of the device while holding the device with both hands, if the input is detected, the screen controller of the device determines whether the horizontal length of the screen of the current device is longer than the vertical length in step 502. Will be judged.

If the current length in the horizontal direction is longer than the length in the vertical direction, that is, in a state such as 201 of FIG. 2 or 301 of FIG. 3, step 503 of FIG. 5 is entered. On the contrary, if the current length in the horizontal direction is shorter than the length in the vertical direction, that is, in a state such as 202 of FIG. 2 or 302 of FIG. 3, step 504 of FIG. 5 is entered.

In operation 503, the screen controller of the device rotates the screen of the device from the long side to the short side and displays a touch screen keyboard on the screen of the device in parallel with the rotated screen. Since this process is the same as the steps 402 to 404 described in the process described with reference to FIG. 4, a detailed description thereof will be omitted.

In operation 504, the screen controller of the device independently terminates the display of the touch screen keyboard, or rotates the displayed screen in the original direction in operation 503 and terminates the display of the touch screen keyboard. In more detail, the length of the horizontal direction being shorter than the length of the vertical direction means that the screen rotation and the touch screen keyboard are currently displayed on the device. When the input sensing unit of the device detects a predetermined input in step 501, The screen controller performs a series of end operations of step 504. Herein, the termination of the touch screen keyboard means that the screen keyboard, which has been displayed on the screen of the device, is not displayed in step 503.

For example, suppose that the user looks at the screen of the device while holding the device with both hands. If the horizontal length of the screen of the current device is shorter than the vertical length, the user clicks the button once. Only the touch screen keyboard display is terminated and the full screen is displayed, and once more clicks may return the device's screen to its original screen display state in which the horizontal length is longer than the vertical length. . In addition, the user ends the display of the touch screen keyboard by an operation of rotating the device by a predetermined angle from the short side to the long side of the screen of the device, and the length of the screen in the horizontal direction is the length of the vertical direction. It may be possible to return to the original display state longer than that.

The button 601 inputs a click by a user to the device, including a hardware button and a software icon through a touch screen. The output unit 602 refers to a typical screen display unit provided in the device.

The input detector 603 detects at least one input of clicking the button 601 or rotating the device by a predetermined angle. The sensed input may be a click on a hardware button or may be a software input via a touch screen. When an input by the user is detected, the input detector 603 notifies the screen controller 604 of this.

The screen controller 604 receives a result detected by the input detector 603 and processes a predetermined command. The input detector 603 stores a screen state immediately before the input is detected and determines a command to be executed according to the input result. Assuming that the user looks at the screen of the device while holding the device with both hands, if the horizontal length of the screen displayed immediately before the input detection is longer, the screen controller 604 is the same as described in step 503 of FIG. 5. Likewise, it will rotate the screen and display the touch screen keyboard on the screen of the device side by side with the rotated screen. On the contrary, if the horizontal length of the screen immediately before the input detection is shorter, the screen controller 604 independently terminates the display of the touch screen keyboard or rotates the screen in the original direction as described in step 504 of FIG. And the display of the touch screen keyboard will be terminated.

The present invention has been described above with reference to the preferred embodiments. Those skilled in the art will understand that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
