Touch method for rotating display direction of display screen by touch gesture

The present invention is a method for rotating a display direction of a display screen, and more particularly to a touch method for rotating a display direction of a display screen by a touch gesture.

According to the recent popularization of smart handheld devices such as tablets and smart phones, they have not only been used for general users to access data and read files, but many service industry clerkes have begun to display smart handheld devices such as tablets. Product or service information.

In addition to the touch panel, the smart handheld device also has the function of automatically setting the display screen. For example, the Republic of China Patent Publication No. 460759 discloses an electronic device capable of automatically rotating a display screen, mainly by sensing. The device detects the swing of the electronic device, the sensor has a U-shaped slide, and a U-shaped slide is provided with a steel ball. When the sensor swings, for example, when changing from erect to lateral or inverted, the steel ball will Moving by gravity in the U-shaped slideway, the electronic device detects the pendulum of the electronic device, and automatically rotates the display direction of the soft object in the electronic device display screen. When the user flips the pendulum of the electronic device, the display screen The soft object will rotate together, and the general display direction has been set in the display, which is usually 0°, 90°, 180°, 270°, so that the display can display the soft object in the above multiple display directions; Nowadays, the detection method of the steel ball being subjected to the gravity in the U-shaped slide is no longer used, and the gyroscope or the gravity sensor is used to detect the swing of the electronic device. Accuracy and reduced both by improving volume.

However, no matter which sensor is used, it is based on the direction of gravity. When the user flips the handheld device, it automatically rotates the display direction of the soft object in the display screen. However, if the user is unable to perform certain conditions, According to gravity or when the user does not want to rotate the display screen according to gravity, the display screen cannot be rotated according to the use requirement; for example, when the user wants to look at the picture horizontally or backwards, if the electronic device is traversed, the display is displayed. The screen is also rotated with it, so the user can't look at the picture horizontally. The automatic rotation setting method is inconvenient. When the service provider uses a smart handheld device such as a tablet computer to provide goods or provide service information, it will usually be hand-held. The screen of the device is placed upwards and flat. At this time, the soft object in the picture can be rotated in the direction of gravity, so the salesman must change the rotary device to operate and display the handheld device to the customer. The display screen is facing the customer or himself. This kind of use is not convenient, especially when the service provider negotiates face-to-face with the customer, it must be 180 degrees. Turn handheld device, very inconvenient, so the direction of gravity based method for automatically rotating the display screen of the inconvenience is still used, the need of improvement.

In view of the above method for automatically rotating the display direction of the soft object in the display screen according to the gravity direction, the technical defect of the soft object in the display screen cannot be rotated according to the user's use requirement, and the main object of the present invention is to provide a touch gesture. A touch method that rotates the display direction of the display screen.

The main technical means used to achieve the above purpose is to enable the touch method of rotating the display direction of the display screen by the touch gesture to be attached to a soft object. After the first direction is displayed, the following steps are performed: identifying a touch gesture including five touch points and their position coordinates; connecting the five touch points according to their position coordinates to form an arc curve Determining the direction of the arc of the curved curve; displaying the soft object after rotating from the first direction to the arc.

The soft object in the above rotating display screen is determined according to the direction of the arc of the curved curve formed by the five touch points, and when the user places the five fingers on the touch panel, the touch gesture forms five The line connecting the touch points will have an arc curve which is approximately curved. The direction of the arc of the curved curve will cause the soft object to rotate and display. Thus, the purpose of rotating the display screen by the touch gesture can be achieved. The user can rotate the display screen according to the direction in which he wants to watch, without limitation, and can rotate the display screen according to the use requirement, and the operation is convenient.

Since the following description must be clearly explained by the vector of the plane coordinate system, the first axial and second axial systems mentioned in the following description are respectively stated as the X-axis and the Y-axis of the plane coordinate system, respectively, and The display direction corresponding to the first axial direction is defined as 0°, the display direction corresponding to the second axial direction is defined as 90°, the display direction of the reverse first axial direction is 180°, and the display direction of the reverse second axial direction is 270°. It is also indicated in FIG. 3 and FIG. 5, but this definition is only used to assist in clearly explaining the technical content of the present invention, and is not limited thereto.

The touch method for rotating the display direction of the display screen by using the touch gesture can be built in various electronic devices with the touch panel to touch The control gesture rotates the display screen to provide the user with the effect of rotating the display screen according to the use requirement, and is used in the existing smart handheld device to solve the defect caused by the automatic rotation of the display screen according to the gravity direction. The touch method for rotating the display direction of the display screen by the touch gesture is as shown in FIG. 1 . After the soft object is displayed in the first direction and then S10, the following steps are performed: identifying five touch points and their positions are identified. a touch gesture S20; the five touch points are respectively connected according to their position coordinates to form an arc curve S30; the arcuate direction S40 of the arc curve is determined; the soft object is from the first When the direction is rotated in the direction of the arc, S50 is displayed.

Please refer to FIG. 2A and FIG. 4A . Taking a tablet computer 10 as an example, when the user naturally places the finger on the touch panel 11 of the tablet 10 with five fingers, it can be formed on the touch panel 11 respectively. The five touch points P ₁ ~ P ₅ , in order to cooperate with the following description, refer to the touch points corresponding to the mother finger, the index finger, the middle finger, the ring finger and the little finger, respectively, from P ₁ to P ₅ . After the touch panel 11 scans and senses the first axial direction and the second axial direction, the five touch points P ₁ P P ₅ on the current touch panel 11 can be identified as shown in FIG. 2B and FIG. 4C respectively. a position coordinate (X ₁ , Y ₁ )~(X ₅ , Y ₅ ) formed by the first axial direction and the second axial direction, and then the position coordinates of the five touch points P ₁ to P ₅ (X ₁ , Y ₁ )~(X ₅ ,Y ₅ ) are sequentially connected into a line, and the user can obtain an approximate curved arc curve 20, 20' due to the natural placement of the five fingers of the user. The curved curve 20, 20' will form an arc mouth. After judging the direction of the arc mouth, the soft object can be rotated from the first direction to the arc mouth, as shown in FIG. 2A and B. When the control gesture forms the arc-shaped direction of the curved curve 20 corresponding to the direction of 270° (ie, the axial direction of the reverse Y-axis), as shown in FIG. 3, the display direction of the soft object 30 (in the case of an image) in the display screen is displayed. That is, the rotation is 270°; and the arcuate direction of the curved curve 20' formed by the touch gesture of FIG. 4A and C corresponds to the direction of 0°, so the rotating soft object will display the direction of the soft object 30 ′ as shown in FIG. 5 . Rotate to 0° To achieve the purpose of rotating the various soft objects (such as the operation interface of the working software, pictures, e-books, etc.) by the touch gesture, and the operation is quite convenient, even if the above-mentioned tablet 10 is placed on the desktop, The soft objects 30, 30' in the display screen can be rotated by the user according to the use requirements according to the use of the touch to correspond to the respective display directions.

Please refer to FIG. 6 for further description of step S30 of forming a curved curve according to the coordinate line of the position of the five touch points. The step includes: setting the coordinates of the five touch points according to the first axis. Sorting, and in this order, the touch points are connected to the closest touch point that is not yet connected to the line S31. Taking FIG. 2B as an example, the position coordinates of the five touch points P ₁ to P ₅ are in the first axial direction. (that is, the size of X ₁ ~ X ₅ ) is sorted, and the order of discharge is: P ₁ , P ₂ , P ₃ , P ₄ , P ₅ , and in this order, the touch point P ₁ is connected to the touch point. P ₂ (the two are closest), the touch point P _{2 is} connected to the touch point P ₃ , the touch point P _{3 is} connected to the touch point P ₄ , and the touch point P _{4 is} connected to the touch point P ₅ . The desired curved curve 20 is connected; the last touch point P _{5 in} this sequence is connected with the first touch point P ₁ , and it is determined whether the closed figure is a pentagon S32, and if so, Complete the line S33 of the curved curve, if otherwise, proceed to the next step; as in the case of FIG. 2B, if the previous step has connected the curved curve 20, the first touch point P ₁ in the above sequence is used. with the last touch point P ₅ Closed line pattern is formed to be a pentagonal shape, this step may correspond to the angle of five five touch points P ₁ ~ P ₅ even out according to a closed pattern whether the sum of 540 °, it is determined whether five The edge shape, for example, when the user operates with the touch gesture shown in FIG. 4A, the corresponding five touch points are also shown in FIG. 4B, and the order of discharging according to the previous steps should be: P ₃ , P ₄ , P ₂ , P ₅ , P ₁ , after connecting in this order, the curved curve will not be obtained, and after the connection forms a closed figure, the five angles corresponding to the five touch points P ₁ ~ P ₅ The total is not 540°, and the connection must be re-established in the following step; the coordinates of the five touch points P ₁ ~ P ₅ are sorted according to the second axis, and the touch points are closest to each other in this order. The touch point that is not yet connected is connected to S34. Taking FIG. 4B as an example, when the same five touch points are sorted according to the second axial direction (ie, the size of Y ₁ ~Y ₅ ), the order is changed to : P ₁ , P ₂ , P ₃ , P ₄ , P ₅ , and in this order, the wiring is further obtained, and the curved curve 20' as shown in Fig. 4C can be obtained.

As illustrated in the above figure, if the normal hand shape is sorted according to the first axial direction and the curved curve 20 cannot be obtained after the connection, the curved curve 20' should be obtained after being sorted according to the second axial direction and connected. To avoid misjudgment of other special touch gestures, after sorting and connecting according to the second axis, further connecting the last touch point in the sequence with the first touch point, and determining whether the closed figure is It is a pentagon S35, and if so, the line S36 of the curved curve is completed, and if not, the step S37 is not operated.

The above steps can be used to connect the curved curves 20, 20' according to the user's touch gesture. The detailed steps of determining the curved curve 20, 20' arc direction S40 are further described below with reference to FIGS. 2B, 4C and FIG. The method includes: taking the position coordinates of the first, third, and fifth touch points P ₁ , P ₃ , and P ₅ respectively according to the sequence of the five touch points connecting the curved curves 20 and 20 ′ (X) ₁ , Y ₁ ), (X ₃ , Y ₃ ), (X ₅ , Y ₅ ) (S41); calculating the position coordinates corresponding to the three touch points P ₁ , P ₃ , and P ₅ forming the center of gravity G of the triangle (X _g , Y _g ) (S42), and in geometric mathematics, the three touch points are calculated to form the coordinates of the center of gravity of the triangle, and only the values of the first axis corresponding to the first axis X ₁ , X ₃ , X are required. ₅ addition and division by 3, corresponding to the second axial value Y ₁ , Y ₃ , Y ₃ plus and divided by 3, respectively, can obtain the position coordinates (X _g , Y _g ) of the center of gravity, where X _g = (X ₁ + X ₃ + X ₅ ) ÷ 3; Y _g = (Y ₁ + Y ₃ + Y ₃ ) ÷ 3; connecting a third touch point P ₃ to the center of gravity G to obtain a vector And determining the arc direction S43 of the curved curves 20, 20' according to the vector.

Since the existing tablet computer 10 is mostly rectangular, and the bottom edge of the display screen of most applications only has a direction of 0°, 90°, 180°, and 270°, in this embodiment, the arc is determined according to the vector. In the mouth direction, the full angle is divided into four quadrants in advance, and each quadrant corresponds to one direction, such as the first quadrant is 315 ° ~ 45 °, which corresponds to the direction of 0 °, the second quadrant is 45 ° ~ 135 °, Corresponds to the direction of 90°, and so on, and calculates the vector Vector angle (ie, the first axis in the coordinate system is 0°, calculated Determining a quadrant corresponding to a vector angle of the vector, and determining a direction corresponding to the quadrant of the vector as an arcuate direction of the curved curve 20, 20'; , the vector in Figure 2B Although the vector angle is not 270°, after the above calculation and judgment, the direction of the arc of the curved curve 20 will be determined as 270°; the vector in Fig. 4C Although the vector angle is not 0°, after the above calculation and judgment, the direction of the arc of the curved curve 20' will be determined as 0°, so that the bottom edge of the display screen rotates smoothly relative to 0°, 90°, 180°. In the future, if the software developer increases the angle at which the display screen can be rotated, the number of the above quadrants can be increased to further increase the arc direction in which the curved curve can be determined, and increase the soft object in the display screen. 30, 30' rotatable angle.

When the user operates the soft object 30, 30' (such as the operation interface, image, etc.) in a touch mode, only five fingers are placed on the touch panel, so that the arc of the curved curve formed by the five fingers is turned to be rotated. In the direction of the screen, the operation of rotating the soft objects 30, 30' can be completed. By the above means, when the tablet is laid flat, and the two users view the display screen of the tablet 10 in different directions, only need to take turns to watch Previously, five fingers were placed on the touch panel 11 first, and the arcuate arc of the curved curve was oriented toward itself, and the soft object in the display screen was rotated corresponding to the viewing direction of the user, without rotating the tablet. The operation is convenient; and the user is not restricted by gravity. When the user has a non-positive image in the e-book, the soft object in the display screen can be rotated by the corresponding touch gesture; in addition, the above The touch gesture only needs to put five fingers on the touch screen, and does not need to move the finger or the like, but the present invention provides a static touch gesture operation, and for the user, The touch rotation mode of the present invention is relatively convenient, and the touch operation mode of the present invention is relatively convenient, and the gesture motion is not easy enough or the motion is not good compared to the general dynamic touch gesture. Correct misrepresentation.
