Touch device and gesture unlocking method thereof

The present invention relates to a touch device and a gesture unlocking method thereof, and more particularly to a touch device having a touch panel and a gesture unlocking method thereof.

Early Personal Digital Assistant (PDA) used a touch panel for users to input commands. In recent years, with the vigorous development of the touch industry, the traditional push-button mobile phone with only the call function has been unable to meet the needs of users. Therefore, in recent years, smart phones have gradually adopted touch panels as human-machine input interfaces to provide users with a new way of communication.

For example, the smart phone is used as a touch device. Please refer to FIG. 1A and FIG. 1B , which are schematic diagrams of unlocking and decrypting a touch device according to the prior art. In order to avoid object collision or other users can easily unlock the touch device, the touch device is provided with a program for unlocking and decrypting. Please refer to FIG. 2 at the same time, which is a partial circuit diagram of the touch device 1 of the prior art. After the user moves the slider to the unlocking position, the touch device 1 calculates the coordinates of the slider after the slider is moved by the touch panel 11 of the touch panel, and transmits the bus bar to the system board of the touch device 1 through the bus bar. The central processing unit 12 confirms whether the coordinates of the moving slider are correct to activate the decryption screen corresponding to the application. As shown in FIG. 1B, if the unlocking gesture of the input moving slider is correct, the touch device 1 displays a screen for inputting a password by the software application 13 to allow the user to further input the unlocking password by using the touch button. After the user inputs the correct password, the operation of the central processing unit 12 is confirmed to be correct, and the unlocking and decrypting operations can be completed.

The above-mentioned unlocking and decrypting process not only confirms the touch coordinates by the touch panel 11 of the touch panel, but also sends the determined touch coordinates to the central processing unit 12 of the touch device 1 for confirmation and starts subsequent operations. application. This process not only increases the transmission time and processing time, but also may cause data transmission errors due to electrostatic discharge or noise interference in the environment.

Please refer to FIG. 3 , which is a flow chart of steps of a gesture unlocking method of a touch device according to a preferred embodiment of the present invention. The gesture unlocking method disclosed in the present invention can be applied to a touch device with a touch panel, such as a mobile phone, a notebook computer, a tablet computer, a personal digital assistant (PDA), a global satellite positioning system (GPS), an e-book, an MP3. Player, touch TV or any electronic product with a touch panel. The gesture unlocking method of this embodiment includes steps S01 to S04.

Please refer to FIG. 3 and FIG. 4 simultaneously, which are schematic diagrams of the touch device of the present invention. First, in step S01, an unlocking gesture data is stored in one of the drivers 211 of the touch panel 21. The unlock gesture data is stored in a memory of the driver 211. The memory of this embodiment may be a flash memory or a read-only memory. The unlock gesture data may be an unlock gesture data built in the electronic product, or may be set by the user to input the unlock gesture data. In addition, the graphics or size of the unlock gesture data may be determined by the user. The graphics of the unlock gesture data may be, for example, dots, lines, circles, squares, triangles, stars, or other graphics, which are not limited to the present invention. Among them, the state of unlocking gesture data is detailed later.

Next, a storage method of storing the unlock gesture data on the drive 211 will be briefly described. Please refer to FIG. 4 and FIG. 5 simultaneously. FIG. 5 is a flow chart showing the steps of the method for storing the unlock gesture data by the touch device 2 of the present invention. The storage method of this embodiment includes steps S11 to S13.

In step S11, the unlocking gesture data setting function is enabled, and the user can open the unlocking gesture data setting function through an application software 221 of the module 22 of the touch device 2, but is not limited to the present invention. The application software may be a built-in software or an amplification software.

In step S12, the unlock gesture data is input. The user inputs a gesture to be set to unlock on the touch panel 21, and the user can arbitrarily determine and input the number of tracks, the track direction, the track path, and the track pattern of the unlock gesture data. Of course, the user can also directly select the gesture that has been built into the application software as the unlock gesture data without re-entering the gesture.

In step S13, the unlock gesture data is determined and stored in the driver 211. At this time, the screen of the touch panel 21 can display the trajectory of the unlock gesture data set by the user, and then the user can confirm, and after being confirmed, it is stored in the memory of the driver 211 of the touch panel 21. Then, as long as the touch device 2 enters the lock mode, the touch device 2 can be unlocked due to unnecessary collision or touch, thereby causing the touch device 2 to perform unnecessary functions, such as touch. Features, call features, page turning, viewing or playback features, and more.

In the step S02 of the gesture unlocking method, the driver 211 receives an operation gesture data from the touch panel 21. If the user wants to unlock the touch device 2 that has entered the lock mode, the operation gesture data is first input to the touch panel 21, so that the driver 211 receives the operation gesture data from the touch panel 21. The time required to input the operation gesture data may be limited to a preset time, for example, 5 seconds or 3 seconds, and the preset time should be avoided too long to avoid spending too much time. Detect operation gesture data.

In step S03, the driver 211 compares the operation gesture data with the unlock gesture data, and transmits a comparison result C to the module 22 of the touch device 2. The driver 211 of the touch panel 21 compares the number of input trajectories of the unlocking gesture data with the operation gesture data, the trajectory direction, the trajectory path, the trajectory pattern or the trajectory input order, etc., to determine the similarity between the unlocking gesture data and the operation gesture data. Degree, and then output a similar or a dissimilar comparison result C to the module 22.

Please refer to FIG. 3 and FIG. 6A to FIG. 6C simultaneously, wherein FIG. 6A to FIG. 6C are schematic diagrams showing changes in the number of unlocking gesture data tracks according to the present invention. In this case, it is determined whether the unlocking gesture data is similar to the operation gesture data, and the number of tracks of the unlocking gesture data and the operation gesture data may be the number of tracks in a single time or the number of tracks in a certain time range. Taking the simplest trajectory as a "point" as an example, if the unlock gesture data is three points (as shown in FIG. 6A), the operation gesture data also needs to be three points; and the unlock gesture data can also be preset. Three points (Fig. 6A), two points (Fig. 6B) and one point (Fig. 6C) are sequentially input in time, and the driver 211 can output one as long as the order of the number of tracks of the gesture data is correctly aligned. Similar alignment results C.

In addition, the number of tracks of the unlock gesture data can also be used as a preset value in conjunction with the coordinate position. As shown in FIG. 7 , the unlock gesture data is, for example, three points, and is located on a diagonal line in the nine-square grid (background), and the number and coordinates of the trajectories (points) input by detecting the unlock gesture data and the operation gesture data are detected. To determine whether they are similar. Wherein, the number of points needs to be consistent, and the coordinate of the point is, for example, within an error range. For example, the three points of the unlocking gesture data are respectively located in the upper left corner, the middle and the lower right corner of the nine-square grid, and the gesture data is operated. Also enter three points in the upper left corner, middle and bottom right corners to unlock. Of course, in other embodiments, the touch panel may not display the nine-square grid background, but may display other patterns or portraits as the background, for example, by touching the two ears or facial features of the portrait, or by touching the partial pattern. Unlock gesture data. When the unlock gesture data is to be set as a line, for example, the eyebrows or lips of the portrait may be depicted, or the outline of the pattern or the like may be drawn as the unlock gesture material.

In addition, the trajectory direction and the trajectory path of the unlock gesture data and the operation gesture data can be utilized as the judgment of whether the degree of similarity is used. In order to know the direction of the trajectory, the input unlock gesture data and the operation gesture data may be numbered. As shown in FIG. 8, the unlock gesture data is defined to input four oblique lines on the touch panel 21a. When judging the touch position, the X value of each touch coordinate can be used as the number of different fingers in a certain time. For example, if four fingers touch the touch panel 21a at the same time, according to the coordinates of the coordinates The X value defines four numbers 1, 2, 3, and 4 (which can represent four fingers, respectively) from left to right. At the next time (for example, the next frame time), the determined coordinate position can know the direction and position of the gesture movement of the number, thereby forming a trajectory path of each finger number. Of course, when the X coordinate values are too close, the Y coordinate can be judged to define the finger number. After the trajectory path input of the unlocking gesture data and the operation gesture data is completed, the overall trajectory pattern of the input unlocking gesture data or the operation gesture data may be determined, and the similarity of the trajectory patterns of the two is compared to determine the unlocking gesture data and Whether the operation gesture data is similar, for example, as long as they are all the same graphics, such as triangles, circles or squares.

Moreover, as shown in FIG. 9, when three circles are respectively input as the unlock gesture data on the touch panel 21b, and when the three circles are not simultaneously input, the system is within a preset time, from left to right. Enter three circles as the unlock gesture data. According to the input trajectory path, for example, the X value or the Y value of the coordinate, and the coordinate position determined at the next time, the overall trajectory pattern, the trajectory direction and the trajectory input order can be known, for example, the unlock gesture data of FIG. The graphics are from the bottom left to the top three circles, so when you enter the gesture data, you must also enter the three circles in order from the bottom left to the right to be similar to the unlock gesture data.

It should be noted that in the trajectory path of unlocking gesture data and operating gesture data, each trajectory path has a starting point, an intermediate point, and an ending point. In order to enhance the difficulty of unlocking, in the manner of comparing the unlocking gesture data with the operation gesture data, for example, comparing the number of tracks, the track direction, the track pattern or the track input order, the comparison unlocking gesture data and the operation gesture may be added. Whether the track coordinates of the data are similar. As long as the coordinate data group of the unlock gesture data track is compared with the coordinate data group of the operation gesture data to determine whether it is within an allowable error range, it can be known whether the unlock gesture data and the operation gesture data are similar. The trajectory of the unlocking gesture data and the operation gesture data can be equally divided into coordinates by interpolation to determine whether it is within the error range, but is not limited to the present invention.

For example, taking the lower left corner of the touch panel as the origin, the X value of the coordinates of the touch panel is divided into 50 grids, and the Y value of the coordinates is divided into 100 grids, so the overall coordinates of the touch panel are (0, 0). ) to (50,100), if the unlocking gesture data one of the lines is (10,70) to (10,40), where the starting point is (10,70) and the ending point is (10,40), if the operation gesture The starting point and the ending point of the data are in the coordinates of the starting point and the ending point of the unlocking gesture data, for example, plus or minus 5, and the starting point of the operation gesture data is required to be (5, 65), (5, 75), Within the range of (15, 75) and (15, 65), and the end point of the operation gesture data shall be within the range of (5, 35), (5, 45), (15, 45) and (15, 65) And the operation gesture data is substantially a straight line, then it can be determined that the unlock gesture data is similar to the operation gesture data. The above error range is only used for illustration, and is not intended to limit the present invention. It is compared with whether the unlocking gesture data and the starting touch coordinates of the operation gesture data are similar, which refers to the initial touch of the unlocking gesture data and the operation gesture data. Whether the distance between the touch marks and the coordinates is, for example, less than 1/4 of the width of the touch panel.

It should be noted that, when step S03 is performed, whether the unlocking gesture data and the operation gesture data are similar, for example, comparing the number of tracks of the unlocking gesture data and the operation gesture data, the track direction, the track pattern, the track input order, and the track coordinates Etc., to confirm that the unlock gesture data is similar or dissimilar to the operation gesture data, and causes the driver 211 to transmit the comparison result C to the module 22 of the touch device 22.

Please refer to FIG. 3 and FIG. 4 again. Finally, in step S04, the module unlocks/locks the touch device 2 according to the comparison result. When the operation gesture data is similar to the unlock gesture data, the driver 211 transmits a similar comparison result C to the microprocessor 222 of the module 22, so that the microprocessor 222 controls the touch device 2 and unlocks the touch device 2, The touch device 2 is brought into an operable mode, for example, a touch function, a call function, a page turning function, a browsing function or a playing function, etc., so that the user operates the touch device 2. However, if the unlock gesture data is not similar to the operation gesture data, the driver 211 transmits a dissimilar comparison result C to the microprocessor 222 of the module 22, and the microprocessor 222 locks the touch device 2, and the touch panel is at this time. The screen of 21 presents a lock screen again, and the user is asked to input the operation gesture data again to unlock the touch panel 21.

In addition, please refer to FIG. 4 , which is a schematic diagram of a touch device according to a preferred embodiment of the present invention. The touch device 2 includes a touch panel 21 and a module 22 . The touch panel 21 has a driver 211. The driver 211 stores an unlock gesture data and receives an operation gesture data, and the driver 211 compares the operation gesture data and the unlock gesture data. The module 22 is electrically connected to the touch panel 21 and unlocks or locks the touch device 2 according to a comparison result C. The unlocking gesture data is stored in one of the memories of the driver 221 . In addition, the module 2 includes an application software 211 and a microprocessor 222. The driver 211 compares the operation gesture data and the unlock gesture data, and transmits the comparison result C to the module 22. When the operation gesture data is similar to the unlock gesture data, the microprocessor 222 of the module 22 controls and unlocks the touch device 2, and when the operation gesture data is not similar to the unlock gesture data, the microprocessor 222 locks the touch device 2 .

The touch panel 21 and the module 22 of the present embodiment have the same technical features as the touch panel 21 and the module 22 in the above embodiments, and thus will not be described again.
