Description

Method of preventing accidental touch

The present invention relates to a method for preventing accidental touch, and more particularly to a method for preventing a touch screen function key of a touch-enabled portable device.

In recent years, the rise of portable communication devices, such as mobile phones and personal digital assistant devices (PDAs), has made people have more and more opportunities to make calls using portable communication devices. Taking mobile phones as an example, many mobile phones have replaced traditional buttons with touch modules for operation. The feature of the touch operation is that the touch module can sense the operation of the user only by approaching or touching the touch module, and the purpose of selecting the function is achieved.

Many times, you may be mistakenly dialed by accident. For example, accidentally press the phone button on the hardware or screen. The hardware call button can be prevented with the button lock, and the screen call button can be prevented with the screen saver. However, when the phone is put into a pocket or a backpack, there is a possibility that the call button on the screen is accidentally triggered and the call is mistakenly dialed without a screen saver.

In summary, the touch module is used in a portable communication device, and there is still a risk of accidental touch. Therefore, how to prevent the risk of accidental touch caused by accidents and to generate a control method of the portable communication device is the object that the present invention attempts to solve.

In view of this, the present invention provides a method for preventing accidental touch, which is suitable for a touch user interface. The method includes the steps of displaying a user interface menu screen on the screen, and the user interface menu screen includes a menu item area and a non-menu item area; when the object clicks on the non-menu item area, a total risk value is accumulated; when the object is selected An application is executed when a program menu item and the total risk value is less than the established total risk value; a warning window is displayed when the object selects a program menu item and the total risk value is greater than the predetermined total risk value.

The above described objects, features, and advantages of the invention will be apparent from the description and appended claims appended claims

1 is a flow chart showing a method of preventing false touches according to an embodiment of the present invention. In this embodiment, the method of preventing false touch is applied to the touch user interface. 2a-2b is a schematic diagram showing a user interface menu screen of a touch device according to an embodiment of the invention.

In step 102, a user interface menu screen 200 is displayed on a screen. Referring to Figure 2a, the user interface menu screen 200 includes a menu item area 210 and a non-menu item area 220 (areas outside the menu item area). The menu item area 210 further includes a catalog menu item 212 and a program menu item 214. The directory menu item 212 is defined to enter the next level user interface menu screen 200 or return to the previous layer user interface menu screen 200 when an item clicks on the menu menu item 212. It is also possible to include other menu item areas and non-menu item areas in the user interface menu screen of the next layer or the previous layer. The program menu item 214 is defined to execute an application, such as a computer or dialing a phone, when the item clicks on the menu item 214.

Referring to FIG. 2a, in the present embodiment, the non-menu item area 220 is divided into a plurality of risk areas, for example, 220a-220g. A plurality of risk areas 220a-220g are set to have a risk value. The risk value is set based on the distance between the plurality of risk regions 220a-220g and the menu item area 210. The risk value of the plurality of risk areas 220a-220g is inversely proportional to the distance of the menu item area 210. In particular, the most recent area from the program menu item 212 (but not the area where the application is executed) has the highest risk value. The farther away from the menu item area, the lower the risk value setting. For example, the risk value of the risk area 220a is set to 9, and the risk value of the risk area 220f is set to 4, but is not limited thereto. In addition, the risk value of the menu item area 210 (including the catalog menu item 212 and the program menu item 214) is set to zero.

Next, at step 104, it is determined whether or not the menu item area 210 is clicked. If not, that is, when the non-menu item area 220 is clicked, the process proceeds to step 106. At step 106, the total risk value is accumulated. Whenever the object clicks on the non-menu item area 220, the risk value of the selected risk area is accumulated. Then return to step 102.

If it is selected in the menu item area 210, it proceeds to step 108. At step 108, a determination is made as to whether or not to select a program menu item 214. If not, indicating that the menu item 212 is selected, the process proceeds to step 110 where the total risk value is zeroed. Then return to step 102. Whether the user intentionally clicks on the directory menu item 212, or selects the directory menu item 212 by non-human factors, because it can enter another layer of the user interface menu screen, there is no error in triggering a specific screen function key. The situation happened. If the program menu item 214 is clicked, for example, in this embodiment, if the screen call button is clicked, the process proceeds to step 112.

At step 112, it is determined whether the total risk value is greater than a predetermined risk value. Manufacturers can set their own established risk values. When the total risk value is greater than the predetermined risk value, it indicates that the wrong touch is judged. For example, the mobile phone screen may be continuously collided by an external force, and the process proceeds to step 114. Referring to Figure 2b, at step 114, a warning window 230 is displayed. Next, at step 116, it is judged whether or not the warning window 230 is canceled. If the warning window 230 is not cancelled, the warning window 230 is continuously displayed to remind the user that the user is currently in a state of false touch. If there is a cancel warning window 230, for example, pressing the cancel button (OK bottom) 232 in Fig. 2b, the warning window 230 is removed from the screen. Then to step 118, the total risk value is returned to zero, and then returns to step 102.

If the total risk value is not greater than the established risk value (ie, less than the established risk value), then the non-external factor is selected as the menu item 214, and the user actually clicks on the program menu item 214 to proceed to step 120. The application is executed at step 120, for example, in this embodiment, the call is made and the risk value is zeroed. For example, when a user wants to make a call, the call button is accurately pressed and it is less likely to touch other areas, so there is no cumulative risk value. According to the above user habits, it can be known that when an object clicks the screen dialing key/program menu item and the total risk value is less than the predetermined risk value, it can be determined that the user really wants to make a call. So the application that performs the call function.
