Detailed ways

FIG. 1 is a schematic flowchart illustrating a touch signal processing method according to an embodiment of the present invention. The touch signal processing method described in this embodiment is applicable to an electronic device, wherein the electronic device includes a touch panel. For example, FIG. 2 is a schematic diagram illustrating how the touch panel 210 of the electronic device 200 reads touch signals according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 at the same time. The electronic device 200 is, for example, a notebook computer, a tablet computer, a personal digital assistant (PDA), a mobile phone, a digital camera, an e-book, a game console, or other electronic devices with a touch panel. . The touch panel 210 can read and/or display a touch signal input by a user. In addition, the electronic device 200 has at least one sensing device for detecting the movement of the electronic device 200 . For example, after summing up the detection results of each sensing device, the movement vector of the electronic device 200 at each time can be calculated. The sensing device may include a gravity sensor (G-sensor), a gyro sensor (gyro sensor), a compass sensor (compass sensor) or other sensors for detecting the movement of the electronic device 200 .

In step S101 , when the electronic device 200 receives the touch signal read by the touch panel 210 , the electronic device 200 will determine whether the motion vector of the touch panel 210 is abnormal. When the touch panel 210 in the electronic device 200 reads the touch signal input by the user, as shown in FIG. As shown), the motion vector u of the electronic device 200 can be calculated, and the electronic device 200 can further determine whether the motion vector u of the touch panel 210 is abnormal. For example, if the user touches the touch panel 210 with too much force and causes the touch panel 210 to move or shake abnormally, the abnormally moving touch panel 210 may cause the user to touch the touch panel 210 by mistake. unexpected location. The electronic device 200 can determine whether to execute the signal compensation operation of the touch signal by judging whether the motion vector u of the touch panel 210 is abnormal. That is to say, according to the movement vector u, the electronic device 200 can determine whether the touch signal of the touch panel 210 is abnormal.

For example, if the motion vector u is greater than a certain preset first critical value, the electronic device 200 may determine that the touch panel 210 moves or shakes abnormally. If the motion vector u is smaller than a predetermined second critical value, the electronic device 200 may determine that the touch panel 210 is in a static state. The above-mentioned second critical value is smaller than the first critical value.

In step S105, when the motion vector u in FIG. 2 is abnormal, the electronic device 200 will record it as the first time point. In step S111 , the electronic device 200 determines whether the motion vector u returns to normal from abnormal. When the motion vector u returns to normal, the electronic device 200 will proceed to step S115 to record the second time point. In other words, the electronic device 200 can detect the period when the motion vector u of the touch panel 210 is abnormal (ie, from the first time point to the second time point).

In step S121 , the electronic device 200 will perform a signal compensation operation of the touch signal during the period from the first time point to the second time point. In this embodiment, the signal compensation action performed by the electronic device 200 can be different according to the input form of the touch signal, wherein the touch signal includes linear input (linear input) signal, key input (push-button input) signal and gesture input. (gestureinput) signal. The key input signal may also be a choose signal. The signal compensation operations performed by the electronic device 200 under different touch signals are described in detail below.

FIG. 3A is a schematic diagram illustrating a signal compensation operation when the touch signal is a linear input signal according to an embodiment of the present invention. Referring to FIG. 3A , it is assumed that the user's hand 20 moves on the touch panel 210 , and a straight line, curve or other linear input is drawn on the touch panel 210 . When the touch panel 210 is in a static state, the electronic device 200 can read normal touch signals through the touch panel 210 , that is, the linear input signal 30 shown in FIG. 3A . When the electronic device 200 determines that the movement vector of the touch panel 210 is abnormal, the electronic device 200 will record the first time point, such as the time point indicated by the arrow 301 . When the touch panel 210 recovers from the abnormal movement state to the static state, that is, when the movement vector of the touch panel 210 returns to normal from the abnormality, the electronic device 200 will record the second time point, such as the time point indicated by the arrow 302 . That is to say, by judging whether the motion vector of the touch panel 210 is abnormal, the electronic device 200 can detect the abnormal linear input signal 31 between the first time point and the second time point of the linear input signal 30 . Next, the electronic device 200 will perform a signal compensation operation on the abnormal linear input signal 31 between the first time point and the second time point.

In detail, the electronic device 200 may provide/display the abnormal touch information 35 on the touch panel 210 to remind the user that the input between the first time point and the second time point is an abnormal linear input signal 31, and Execute signal compensation action. The content of the touch abnormality information 35 is, for example, "abnormal shaking occurs" or other prompt information.

This embodiment does not limit the signal compensation action performed on the abnormal linear input signal 31 between the first time point and the second time point. The above signal compensation actions can be determined according to actual product design requirements. For example, FIG. 3B is a schematic diagram illustrating a signal compensation operation when the touch signal is a linear input signal according to an embodiment of the present invention. As shown in FIG. 3B , the above signal compensation action can stop displaying the linear input signal 30 at the first time point (as indicated by the arrow 301 ), and resume displaying the linear input signal 30 at the second time point (as indicated by the arrow 302 ). . In another embodiment, the signal compensation action includes deleting the touch signal read during the period from the first time point to the second time point. In other embodiments, the signal compensation action also allows the user to selectively delete or retain the abnormal linear input signal 31 between the first time point and the second time point.

In another embodiment, the electronic device 200 may calculate/compensate the touch signal between the first time point and the second time point. For example, FIG. 3C is a schematic diagram illustrating a signal compensation operation when the touch signal is a linear input signal according to another embodiment of the present invention. As shown in FIG. 3C , the signal compensation action can be based on the touch signal before the first time point (ie, the linear input signal 30 ), and/or based on the touch signal after the second time point, to compensate the signal at the first time point. Touch signals during the period from the point to the second time point. At this time, the electronic device 200 can simulate the linear input signal 30 from the first time point to the second time point (as indicated by the arrow 302) through calculation according to the linear input signal 30 before the first time point (as indicated by the arrow 301). mark), that is, the linear input signal 32 . The aforementioned method for calculating the linear input signal 32 may be extrapolation, interpolation, inertial law or other projection algorithms. In another embodiment, the signal compensation action allows the user to re-input the touch signal between the first time point and the second time point to replace the abnormal linear input signal 31 . In this way, the electronic device 200 can compensate the touch signal received during the period when the motion vector of the touch panel 210 is abnormal, thereby avoiding wrong input results.

FIG. 4 is a schematic diagram illustrating a signal compensation operation when the touch signal is a key input signal according to another embodiment of the present invention. Referring to FIG. 4 , the user can input key input signals by touching the options (or virtual keys, such as options 42 , 44 and 46 ) displayed on the touch panel 210 . Here, it is assumed that the user's hand 20 wants to press the option 42 on the touch panel 210 . Under normal conditions, the touch signal of the touch panel 210 read by the electronic device 200 should be within the area occupied by the option 42 , so the electronic device 200 can undoubtedly execute the function corresponding to the option 42 . When the touch panel 210 moves or shakes abnormally, if the user's hand 20 wants to click option 42 on the touch panel 210, the touch signal of the touch panel 210 may exceed the area occupied by option 42. , and may even accidentally trigger unintended options (such as options 44 or 46). At this time, the electronic device 200 cannot confirm whether the function corresponding to the option 42 should be executed, or even malfunction (such as triggering an unexpected option) may even occur.

Therefore, when the electronic device 200 determines that the motion vector of the touch panel 210 is abnormal, the electronic device 200 will record the first time point. When the electronic device 200 determines that the motion vector of the touch panel 210 returns to normal from abnormal, the electronic device 200 will record the second time point. When the touch signal of the touch panel 210 is a key input signal, the signal compensation action performed by the electronic device 200 includes ignoring the touch signal between the first time point and the second time point, and requiring the user to re-input the touch signal. control signal (for example, re-click option 42, 44 or 46). In detail, the signal compensation action can ignore the key input signal during the period from the first time point to the second time point, and provide touch abnormality information 45 to request re-input of the key input signal. In this way, the user can choose whether to re-input the touch signal according to the prompt of the touch abnormality information 45 to avoid getting a wrong input result.

FIG. 5 is a schematic diagram illustrating a signal compensation operation when the touch signal is a gesture input signal according to another embodiment of the present invention. Referring to FIG. 5 , the touch panel 210 can read the gesture input signal 50 input by the user, for example, the user's hand 20 makes a gesture of sliding, pulling, pressing or pinching on the touch panel 210 . When the touch panel 210 reads the gesture input signal 50 , if the electronic device 200 determines that the movement vector of the touch panel 210 is abnormal, the electronic device 200 will record the first time point. When the electronic device 200 determines that the motion vector of the touch panel 210 returns to normal from abnormal, the electronic device 200 will record the second time point. That is to say, the gesture input signal 50 is an abnormal gesture input signal between the first time point and the second time point, and the electronic device 200 will execute the signal compensation operation between the first time point and the second time point. In detail, the signal compensation action can ignore the gesture input signal 50 before the second time point, and provide touch abnormality information 55 to remind the user to perform a gesture action again, so that the touch panel 210 reads the gesture input signal again and Avoid getting wrong input results.
