Continuing, a description is provided of a plurality of user interface setting methods of a mobile device having no physical button frame provided by an embodiment of the present invention. As shown in Figs. 7A-7C, for the execution of the switching power supply, the first setting method is to set the touch action to a preset touch area including the right side wall of the deep bezel structure 20 (see Fig. 7A). For example, the deep pressure can be set to turn on the power, and the deep pressure can be set to turn off the power for a period of time. The second setting method is to set the touch action to include a preset touch area of the right side wall of the deep frame structure 20, and press the frame The two touch areas on the left wall of the structure 20 (see FIG. 7B). For example, you can set one of the preset touch areas on the right wall and press the two touch areas on the left wall to turn on the power. After a period of time, the power is turned off. The third setting method is to set the touch action to simultaneously slide a large range of touch areas on the left and right sides of the frame structure 20 (see Figure 7C). For example, you can set the upper slide , Slide down are power on, power off. At the same time, you can set the touch action to turn off the power. A pop-up menu on the screen has options to turn off the power or restart the device for selection.

As shown in Figures 7D-7F, the first setting method for performing volume adjustment actions is to set the touch action to include a preset touch area on the right side wall of the deep bezel structure 20 (see Figure 7D). For example, the deep pressure can be set to turn on the volume adjustment function, and the deep pressure can be set to turn off the volume adjustment function for a period of time. The second setting method is to set the touch action to include a preset touch area on the right side wall of the deep frame structure 20, And simultaneously press a touch area on the left wall of the frame structure (see FIG. 7E). For example, you can set a preset touch area on the right wall and press a touch area on the left wall to turn on the volume adjustment function. If this action is maintained for a period of time, the volume adjustment function is turned off. The third setting method is to set the touch action by pressing a touch area on the left wall of the frame structure 20 and sliding a small section of the left and right wall of the frame structure 20 For the touch area (see Figure 7F), for example, you can set the volume up and volume down, respectively. At the same time, the touch action that can be set to turn on the volume adjustment function will have a volume adjustment bar on the screen to adjust the volume, and the touch action that can be set to turn off the volume adjustment function will hide the volume adjustment bar on the screen.

As shown in Figures 7G-7I, the first setting method for the camera mode execution action is to touch the mobile device's back panel and press a touch area on the right side wall of the bezel structure 20, and at the same time Press a touch area on the left wall of the frame structure 20 (see Figure 7G). For example, it can be set to the portrait mode of the photo or selfie function. The second setting method is to set the touch action to include a simulated photo action. Hold the mobile device horizontally and press the touch area on the left and right sides of the frame structure 20, and then press down one touch area (see Figure 7H). For example, it can be set as a landscape with a photo or selfie function. Mode; the third setting method is to set the touch action to simulate the camera action, and hold the mobile device horizontally with two hands to slide the touch area on the left and right sides of the frame structure 20 (see Figure 7I), for example , You can set slide up and slide down (slide left and right when viewed horizontally) to zoom in and zoom out respectively.

The operation mode set in the above user interface takes the user's dominant hand as the right hand as an example. When the mobile device is held upright with the right hand, it is mainly set to facilitate the user to use the right thumb to operate the touch on the right wall of the frame structure 20. Area with the touch area of the left wall operated by the rest of the fingers to assist; when the mobile device is held horizontally with both hands, it is convenient for the user to hold the right wall and the left wall of the frame structure 20 with both hands for operation . The above content is only an example to be explained in conjunction with the drawings, and is not used to limit the operation mode of the user setting interface, and the appearance in the drawings is only for illustration, and is not intended to limit the rights protected by the present invention. range.

In summary, according to the present invention, a mobile device with a frame without a physical button is configured with a high-frequency sensor configured on the frame structure on the side of the mobile device body to detect touch behavior, thereby replacing the current Mechanical physical buttons are side buttons such as power button and volume adjustment button. Because the high-frequency sensor is hidden inside the frame structure, it can avoid the problem of the surface of the fuselage being difficult to clean and easy to remain dirty. The waterproof design is not required at extra cost, and it will not destroy the overall harmony and beauty of the mobile device. The overall shape is easier to design. Furthermore, the present invention can adjust user interface settings by combining pressing pressure channels, pressing time, sliding direction, and touch actions such as user gestures to complete common functions such as power on / off, volume adjustment, camera mode selection, and focus adjustment. In this way, it can fully meet the operating needs of different usage habits, thereby improving the practicability and commercial value of the product.
