Portable communication device and method for adjusting multiple touch signals

The present invention relates to a portable communication device and a method for adjusting a plurality of touch signals, and more particularly to a portable type that is adjacent to a plurality of touch points and generates a relative position signal different from one of the touch points. Communication device and method for adjusting multiple touch signals.

With the development of electronic communication technology, portable devices such as mobile phones, smart phones or personal digital assistants (PDAs) have become indispensable items in modern human life. In order to attract the attention of consumers, the manufacturers of the various factories have a place in the market for the products they produce, and they have developed new portable devices with special functions and convenient operation.

Today, whether it is mobile phones, personal digital assistants or smart phones, many of them have touch keyboards. Unlike hardware keyboards, some touch keyboards use a software-based method to display a keyboard directly on the display module of the communication device for the user to type or perform other functions. You can select the touch point on the keyboard.

However, portable communication devices such as mobile phones, personal digital assistants, or smart phones generally have a common feature, that is, the size of the display panel of the display module is usually small, so when the function option graphic on the touch screen is relatively small, Hours, when the user wants to tap the function option with the finger, the finger often obscures the option graphic that the user wants to touch, so that the user cannot confirm whether to select the function option. Moreover, because the function option graphic is too small, it is often impossible to visually confirm which part of the finger is being touched. Touch the display module. Therefore, when the user uses the conventional portable communication device, the user often accidentally touches the function option that is not selected.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a user performing a touch operation on a conventional portable communication device. FIG. 1 illustrates a portable communication device 1 and an object 13 to be tested, that is, a user's finger. The portable communication device 1 includes a display module 11 including a message display area 121 and a plurality of function options 123. In this example, the plural function option 123 is a touch keyboard. When the user wants to use the touch keyboard for typing or function selection, just touch the touch keyboard. As can be seen from Fig. 1, the keys of the touch keyboard are small and closely arranged, and the area of the user's fingers is relatively large. As far as the average user is concerned, whether the finger is used or the other finger is used for the touch operation, it is easy to cause a false touch. For example, in the first figure, when the user wants to select the letter "m" in the touch keyboard, since the area of the finger is much larger than the area of the letter "m", the touch is often pressed together. The other buttons around the letter "m" may be the letter "j", the letter "k" or the letter "n", resulting in a false touch.

Therefore, a portable communication device can effectively determine the function options that the user really wants to touch when using a finger or other object to be tested to perform a touch of a small size option, and effectively reduce the false touch. Occurrence is one of the most important topics at present.

In other embodiments, the object to be tested may also be a touch tool attached to the portable communication device, such as a stylus.

When the user wants to press the letter of the touch keyboard, for example, if the user wants to press the letter "h", the user first presses the area under the letter "h", and then the touch module of the portable communication device 3 ( The figure is not shown, because it is located below the display module 31) to sense the pressing of the user's finger, and generates a plurality of touch signals representing the positions of the touch points touched. At this time, the processing module of the portable communication device 3 (not shown, because it is located below the display module 31) generates a relative position signal of the user's finger to the display module 31 according to the plurality of touch signals. The relative position signal is used to cause the display module 31 to display a pointing graphic, such as the indicator 324 in FIG. 3a. As can be seen from the figure, the indicator 324 is referred to as the letter "h", partially overlapping the letter "h", and the indicator 324 is slightly offset from the user's pressing area. Thereby, the user can clearly confirm the function to be selected. That is, the display module 31 is adapted to display the indicator in addition to the position of the touched point of the touch due to the relative position signal.

Please refer to FIG. 3b, which is a schematic diagram of a touch operation of a third embodiment of the portable communication device of the present invention. FIG. 3b illustrates a portable communication device 4 including a display module 41 for displaying a plurality of function options. For example, in FIG. 3b, the display module 41 also displays a plurality of function options 423, which is a touch keyboard. In this embodiment, The object to be tested 43 is a finger of the user. In other embodiments, the object to be tested may also be a touch tool attached to the portable communication device, such as a stylus. The third embodiment is mainly different from the second embodiment in that the indicators displayed by the display module 41 are different, as described below.

When the user wants to press the letter of the touch keyboard, for example, the user wants to press the letter "j", the user first roughly presses the area below the letter "j". At this time, the processing module of the portable communication device 4 (not shown, because it is located below the display module 41) generates a relative position signal of the user's finger to the display module 41 according to the plurality of touch signals. The relative position signal is used to cause the display module 41 to display an indicator, such as the indicator 424 in FIG. 3b, which is to highlight the letter “j” covered by the user's fingertip (indicated by a thick black frame). As can be seen from the figure, the indicator 424 is a reversed white figure of the letter "j", which is suitable for indicating the letter "j", and the indicator 424 is slightly deviated from the user pressing area. In this way, the user can also clearly confirm the function that he or she will select. That is, the display module 41 is adapted to display the indicator within the position of the touched points that are touched by the relative position signal. Similarly, in other embodiments, the processing module can directly trigger the letter "j" according to the pressing of the user's finger.

For explanation. The computing module 521 can estimate an average distance according to the distance between the touched touch points 70, and the average distance can represent the area of the current touch object and the pressing position. The computing module 521 also generates an average distance signal 5212 accordingly. The computing module 521 can estimate an average pointing according to the position of the touched touch points 70. The average pointing can represent the direction of the current object to be measured. The computing module 521 simultaneously generates an average pointing signal 5213.

As described above, in the present embodiment, based on the average distance and the average pointing, the pressed position of the object to be tested is known, which is approximately the letters "h", "j", "n", and "m" of the touch keyboard. In the vicinity, the touch direction is about right to the upper left. The processing module 54 can generate a relative position signal 5411 according to the average distance signal 5212 and the average pointing signal 5213.
