Description

Touch device and gesture judgment method thereof

technical field

The invention relates to a touch device, in particular to a control device capable of correctly judging touch gestures.

Background technique

In order to facilitate users to replace the mouse function, the touch device or external touch device of a notebook computer basically has a cursor control function, a left button function and a right button function. Added "edge swipe gesture control function". For example, when the computer system enables the window function bar hiding function, when the user uses the touch device to perform cursor control functions, left-click functions, and right-click functions, the window function bar is hidden. Once the touch device determines that the current When the user control gesture is "edge swipe", the computer system will automatically display the hidden function bar function on the window screen for the user to click; in addition, the page switching function is also applicable.

At present, the computer system provider Microsoft has formulated the judgment principle of "edge swipe gesture", but the judgment rate is too low after the actual use with the touch device, which causes inconvenience in use, which will be described in detail below.

First of all, please refer to FIG. 6, the touch control device 10 of a notebook computer is designed as a left button function and a right button function according to the habit of use on the front left and right sides, and the computer system can be controlled by clicking the left and right sides. Execute the left button function and the right button function; as for the "edge swipe gesture control function", it is regulated in the first area near the left side, near right side and near rear side of the touch device. As shown in FIG. 7 , the touch device 10 with edge swipe gesture judgment function is preset with “first region width W”, “object movement distance R”, “object movement angle upper limit α _T ” and “object movement angle lower limit α _B ”, and the judgment method includes the following steps:

Reading several pieces of location information according to a scanning time period within a certain period of time, wherein the first piece of location information falls within the first area;

Calculate the moving direction and moving distance of a single object based on the first position information and other position information;

When it is determined that the moving direction of the object falls within the angle range between the upper limit α _T and the lower limit α _B of the preset moving angle, and the moving distance exceeds the moving distance R of the object, it is determined as an edge swipe gesture.

When a finger slides into an edge of the touch device from the casing, the first position information of the touch device 10 must fall into the first area, and the judgment step of the edge swipe gesture is performed; that is, when the moving direction of the object is satisfied The preset movement angle, as long as the movement distance of the object exceeds the movement distance within a certain period of time, it is judged as an edge swipe gesture.

However, the above judgment method still has a certain misjudgment rate in actual use, one of which is caused by assembly defects in the mechanism; please refer to FIG. Its top surface cannot be flush with the top surface of the notebook computer casing 20 and there is a height difference, so that when the user's finger touches and slides from the casing 20 to the touch device 10, the first position information cannot meet the condition of falling into the first area , instead of correctly judging this gesture as an edge swipe gesture. Another reason for the misjudgment of the edge swipe gesture is: the width of the first area is generally set so as not to interfere with the normal cursor control, so its width will not be too wide, so when the finger slides directly from the notebook computer casing 20 into the touch device quickly At 10 o'clock, the first position information read by the touch device according to the built-in scanning time may not fall into the first area because the finger swipe is too fast, so the edge swipe gesture cannot be correctly judged.

In addition to the technical problem that the above judgment method cannot correctly judge the edge swipe gesture, since the conditions for judging the edge swipe gesture still include the moving direction and moving distance, if the moving distance is not set properly, it is easy to misjudge that the user is slightly tilted The point-press gesture is misjudged as an edge swipe gesture, because the judgment conditions adopted by the current edge swipe gesture judgment method cannot effectively improve the judgment accuracy of the edge swipe gesture.

Therefore, the misjudgment rate of the edge swipe gesture is still high in the current touch device with the edge swipe gesture control function, so further improvement is necessary.

Preferably, among the preset values of several sub-regions preset by the control circuit, the preset value corresponding to the sub-region far away from the side edge of the sensing substrate is greater than that corresponding to the sub-region close to the side edge of the touch device. default value.

Preferably, the gesture judging program of the control circuit also includes a step of judging the sliding direction of the object, that is, comparing each piece of position information with the next piece of position information to determine the displacement direction of an object. When one side edge of the sensing substrate faces away from the side edge and the displacement difference is greater than the preset value, it is determined that the action is an edge swipe gesture.

Another object of the present invention is to provide a gesture judgment method for a touch device, including:

Please refer to FIG. 1A , the touch device 10 of the present invention mainly includes a sensing substrate 11 in this embodiment, a sensing circuit is formed on the upper surface of the sensing substrate 11, and a protective layer 12 can be provided on the upper surface of the sensing circuit. , and the lower surface of the sensing substrate 11 is provided with a physical switch 111 and a control circuit 112, wherein the control circuit 112 is electrically connected with the sensing circuit and the physical switch 111 on the upper surface, and a support plate 13 is provided on the lower surface to Fastened to the casing of electronic devices such as laptop computers. The control circuit 112 mainly judges various touch gestures of the touch substrate 11. Basically, the gestures that can be judged include cursor control gestures, left button press gestures, and right button press gestures; and the edge swipe gesture judgment method of the present invention is the The control circuit 112 further adds an edge swipe gesture determination program.

Generally speaking, computer operating systems (such as Windows ^™ ) provide hot key (Hot Key) settings, allowing users to cooperate with standard keyboard function keys or key combinations to quickly generate or activate the function bar corresponding to the hot key, such as using The operator simultaneously presses the WindowsKey button and the letter Z button on the standard computer keyboard to generate a corresponding hotkey signal, and after being received by the computer operating system, an application program function list is generated.

Since the computer operating system accepts hotkey settings, please refer to FIG. 1B. The touch device of this embodiment can cooperate with the computer operating system to judge gestures and execute or generate corresponding functions, that is, when the user makes a swipe on the touch device After the gesture, the driver unit of the system kernel layer (Kernel Layer) will judge the swipe gesture, and notify the application program of the upper user interface layer (User Layer), and then the application program (Application) will make the swipe gesture The corresponding hotkey signal is transmitted to the computer operating system (Operation System), which is also the user interface layer. After receiving the hotkey signal, the computer operating system executes the corresponding hotkey function. Swipe the edge from left to right, once it is successfully recognized, the swipe gesture judged by the present invention will cause the computer operating system to activate the application switching function.

Please refer to FIG. 3A , a preferred embodiment of the edge swipe gesture determination method of the present invention includes the following steps:

A first area D_right is preset, wherein the first area D_right maintains a distance d1 from a side edge of the touch device 10; that is, the upper surface of the sensing substrate of the touch device 10 defines the first area, the first area keep a distance from one side edge thereof;

Reading several pieces of position information of the object on the touch device 10 within a preset time;

judging whether the first piece of location information among the pieces of information falls within the first area;

If so, then determine whether there is a displacement difference d11 between the first pen position information and other pen position information; and

If yes, and the displacement difference is greater than a preset value, it is determined that the action is an edge swipe gesture; wherein, the preset value is based on the swipe speed of a general swipe gesture passing through the first area and the preset value of the touch device The scan time is set.

Please refer to FIG. 2 and FIG. 3A to FIG. 3C . The touch device can plan up to three right, left, and upper first regions D_right, D_left, and D_up for swiping in different directions. Therefore, after reading the first piece of position information on the touch device, first judge the area that falls into the three right, left, and upper first areas D_right, D_left, and D_up, and then determine whether it is an edge scan. Swipe gesture.

First, as shown in Figure 3A, if the first position information S10 is read in at time t1, and the object is determined to be located on the first right area D_right S11, then the next position information S111 is read at time t2, and then the two are calculated. The displacement difference between the pen position information, and judge whether the displacement difference exceeds the preset value S112; if so, judge it as an edge swipe gesture S113; For the displacement difference, until the displacement difference between any piece of position information and the first piece of position information is greater than the preset value within a preset time S114, then output the last position information S115.

Since the right edge area D_right is close to the right edge of the touch device 10, it is standardized for judging the gesture of swiping from right to left. Therefore, the present invention can further add a step of swiping direction, that is, the position information of each stroke and the following A piece of position information is compared to determine the displacement direction of an object. When all the displacement directions satisfy the direction from one edge of the touch device 10 to the middle direction of the touch device 10 (swiping direction), and the displacement difference is greater than the Only when the default value is used, the action is judged to be an edge swipe gesture; for the first right area D_right, the X-axis coordinates Xa and Xa+1 of each piece of location information and the next piece of location information can determine whether the displacement direction satisfies the Swipe direction; that is to say, assuming that the X-axis coordinates of the touch device increase from left to right, and the Y-axis coordinates increase from top to bottom, after the above two object positions are calculated, further judgment can be made Whether the X-axis coordinate Xa+1 of the first location information is greater than the X-coordinate Xa of the next location information, and if these conditions are met, it is determined as an edge swipe gesture to avoid misjudging the wrong touch of the opposite direction gesture .

Similarly, as shown in Figure 3B, if the first piece of position information S10 is read at time t1, and it is judged that it falls into the first near-left area D_left after S11 and S12, the next piece of position information is read at time t2 S121, then determine the displacement difference between the two position information, and determine whether the displacement difference exceeds the preset displacement S122; if so, judge it as an edge swipe gesture S123; The position information is compared with the displacement difference until the displacement difference between any piece of position information and the first piece of position information is greater than the preset value within a preset time S124, and then the last position information is output S125. Similarly, the specification of the first left area D_left is to judge the gesture of swiping from left to right, so it can be judged whether the X-axis coordinate Xb of the first position information is smaller than the X coordinate Xb+1 of the next position information, If all these conditions are met, it is determined as an edge swipe gesture, so as to avoid misjudgment of a false touch of a gesture in the opposite direction.

Furthermore, as shown in Figure 3C, if the first position information S10 is read at time t1, and it is determined to fall into the first area D_up after S11, S12, S13, the next position information is read at time t2 S131, then calculate the displacement difference between the two pieces of position information, and judge whether the displacement difference exceeds the preset value S132; if so, judge it as an edge swipe gesture S133; The position information is compared with the displacement difference until the displacement difference between any piece of position information and the first piece of position information is greater than the preset value within a preset time S134, and then the last position information is output S135. Since FIG. 3C shows that the touch device 10 provides an upper first area D_up to standardize the gesture of swiping from up to down, it can be judged whether the Y-axis coordinate Yc of the first position information is higher than that of the second position information. The Y coordinate Yc+1 is small, and if these conditions are met, it is determined as an edge swipe gesture, so as to avoid misjudgment of a gesture in the opposite direction.

Since the above embodiment uses the displacement difference to judge whether it exceeds the preset value, mainly because the sliding gesture moves faster than the general gesture, another preferred embodiment of the present invention directly judges whether the moving speed of the object meets the preset value, It is used as the basis for judging whether it is a swipe gesture; that is, after reading several pieces of information, it is judged whether the first piece of location information falls within the first area, and the object is judged according to the number of pieces of location information If the first piece of position information falls on the first area and the moving speed is greater than a preset value, then the action of the object is determined to be an edge swipe gesture.

Furthermore, the above-mentioned embodiment only sets a single displacement for judgment, and the judgment accuracy is still not optimal. Therefore, in order to further improve the judgment accuracy of the edge swiping gesture, please refer to FIG. 4 , when the finger is swiping the edge, The speed of the sliding finger near the outside of the touch device 10 must be lower than the speed near the inside. Therefore, the present invention further subdivides the first area D into a plurality of parallel sub-areas D1~D3 from the outside to the inside, and corresponds to multiple sub-areas. The sub-areas D1-D3 are preset with different preset values (R1-R3); among the plurality of sub-areas, the preset values corresponding to the sub-areas away from the side edge of the touch device are larger than the sub-areas close to the side edge The corresponding preset values of the multiple sub-regions D1-D3 increase from the edge of the closest touch device according to the swiping direction (R1<R2<R3). Therefore, the distance between the position of the object falling in one of the sub-regions D1, D2, D3 and the position of the next object must exceed the displacement corresponding to the sub-region before it is judged as an edge swipe gesture.

Please refer to FIG. 5A , in the right first region D_right near the touch device 10, there are three sub-regions D1~D3 arranged side by side from the outside to the inside, corresponding to three sets of preset values (R1~R3); When the finger first lands on the sub-area D1, the control circuit of the touch device 10 reads several pieces of position information with the scanning time (t1~t2 time is about 12.5ms), and calculates the first position information and the subsequent positions After the displacement difference d11 between the information is compared with the preset value (R1) of the sub-region D1, it is judged whether the preset value (R1) has been exceeded, and if so, it is judged as an edge swipe gesture (d11>R1).

As shown in FIG. 5B , if the finger lands on the sub-region D2 first, the control circuit of the touch device 10 reads several pieces of position information continuously in the scan time, and calculates the position information of the first piece and the position information of the subsequent pieces. After the displacement difference d12 between them is compared with the preset value (R2) of the D2 sub-area, whether the displacement amount R2 exceeds the preset value, if so, it is judged as an edge swipe gesture (d12>R2).

As shown in FIG. 5C , if the finger lands on the sub-region D3 first, the control circuit of the touch device 10 reads several pieces of position information continuously in a scanning cycle, and calculates the position information of the first piece and the position information of the subsequent pieces. After the displacement difference d13, it is compared with the preset value R3 of the sub-region D3 to see if the preset value R3 has been exceeded, and if so, it is judged as an edge swipe gesture (d13>R3).

From Figure 4A to Figure 4C, it can be seen that if the user does perform an edge swipe action, the speed of the finger in the D1~D3 sub-areas is indeed different during the swipe period, that is, it can be seen that several pieces of position information are captured at the same scanning time, The displacement difference in the near outer sub-region is shorter than the displacement difference in the inner sub-region; therefore, in this embodiment, the first region is further divided into a plurality of sub-regions, and different preset values are preset respectively, so it can effectively improve Judge the correctness of edge swiping gestures and reduce misjudgments.

To sum up, since the first area of the present invention maintains a distance from the side of the touch device, most of the fingers of the swipe gesture can fall into the first area, improving the accuracy of the first position information. The condition of the first area solves the problem that the first position information read cannot fall into the first area due to the height difference between the touch device and the casing; then, the present invention only needs to judge the first position information and There is a displacement difference in other pen position information, and the displacement difference with one of the position information obtained within a preset time exceeds the preset value, or the moving speed of the object judged based on multiple position information is greater than the preset value, it can be judged is an edge swipe gesture; wherein, the preset value for judging the displacement difference is set according to the swipe speed of the general swipe gesture passing through the first area and the preset scanning time of the touch device, so when the judged displacement difference is greater than the preset value, When the value is set, it means that the initial speed of the finger falling into the first area is non-zero, and it conforms to the finger speed of the edge swipe gesture, and it is judged as an edge swipe gesture; therefore, the present invention can correctly identify the edge swipe Gestures, so it can be applied to touch devices such as touch pads or touch screens.

Although the present invention has been disclosed above with preferred embodiments, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so the protection scope of the present invention should be based on the scope defined in the claims.
