Description

An information processing method and electronic device

technical field

The present application relates to the field of electronic equipment, in particular to an information processing method and electronic equipment.

Background technique

Multi-touch is a technology implemented jointly by human-computer interaction technology and hardware devices. It can accept touch from multiple points on the screen at the same time for human-computer interaction without traditional input devices (mouse, keyboard, etc.). operate. To support multi-touch operations, tablets and monitors typically use projected capacitive technology (PCT), which utilizes a mutual capacitance screen as a touch panel. The mutual capacitance screen uses ITO to make horizontal electrodes and vertical electrodes on the glass surface. When a finger touches the capacitive screen, it affects the coupling between the two electrodes near the touch point, thereby changing the capacitance between the two electrodes. When detecting the mutual capacitance, the longitudinal electrodes send excitation signals sequentially, and all the horizontal electrodes receive the signals simultaneously, so that the capacitance values at the intersection points of all horizontal and vertical electrodes can be obtained. According to the data of the two-dimensional capacitance variation of the touch screen, the coordinates of each touch point can be calculated. Therefore, even if there are multiple touch points on the touch screen, the real coordinates of each touch point can be calculated.

At present, the Win 8 system can support more than 5 points of touch operation. In order to meet the operating conditions of the Win 8 system, the product needs to pass the "distance between several points" in the Win8Touch WHQL pe-test (win8 touch bottom test) Test, and passing this test requires that the capacitive screen can distinguish different touch points that are closely spaced without being confused as an object with a specific shape.

Furthermore, there is a technical problem that the touch point cannot be correctly identified, so the wrong response to the operation will be made, and the function expected by the user cannot be realized.

In addition, in the prior art, when detecting touch points, full-screen scanning is required, that is, each point on the touch display unit needs to detect the induced voltage, so there is a technical problem of heavy workload and time-consuming.

Embodiments of the present invention provide an information processing method and an electronic device, which are used to solve the problem of misjudgment often occurring in electronic devices in the prior art, where different touch points cannot be distinguished, and they are mixed into one with a specific shape. The technical problem of the object achieves the technical effect of distinguishing multiple different touch points in succession.

The technical solution in the embodiment of the present application is to solve the above problems, and the general idea is as follows:

By obtaining the first induced voltage value of the i-th first point on the first track corresponding to the first sliding operation performed by the first operating body, and the i-th first point on the second track corresponding to the second sliding operation performed by the second operating body The second induced voltage value of the i second point and the third induced voltage value of the ith third point on the connecting line between the ith first point and the ith second point, determine the Whether the third induced voltage value is greater than the first induced voltage value and the second induced voltage value, the first judgment result is obtained, when taking i from 1 to M, if it is judged that there are M first judgment results If the first determination result of the preset percentage satisfies that the third induced voltage value is greater than the first induced voltage value and the second induced voltage value, then the M touch points are invalid touch points.

In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

An embodiment of the present invention provides an information processing method, which is applied to an electronic device including a touch display unit, and the specific implementation process is shown in FIG. 1 . Wherein, the electronic device may be a mobile phone or a tablet computer, etc., and the touch display unit may be a capacitive touch screen or a resistive touch screen. In the embodiment of the present invention, only two operating bodies perform touch operations on the touch display unit at the same time as an example. In addition, the touch display unit can accept simultaneous touch operations by more than two operating bodies. The method comprises the steps of:

Step 101: Detect whether there is a first sliding operation performed by a first operating body and a second sliding operation performed by a second operating body on the touch display unit.

In a specific embodiment, the operating body may be a finger or a stylus, and the touch display unit may determine whether there is a sliding operation by detecting the induced voltage value on the screen.

After step 101 is completed, enter step 102: sometimes, in response to the first sliding operation, obtain a first trajectory; in response to the second sliding operation, obtain a second trajectory, wherein the first trajectory is consistent with the second The trajectories are two trajectories with no overlap.

In a specific embodiment, when there is a sliding operation as described in step 101, the first trajectory corresponding to the first sliding operation and the second trajectory corresponding to the second sliding operation are obtained in response to the sliding operation respectively, in order to avoid inaccurate Distinguishing the first track and the second track, wherein the first track and the second track are two tracks that do not overlap, such as: it can be two tracks that are parallel to each other, specifically, they can be parallel to each other Two straight-line trajectories can also be two mutually parallel curved trajectories.

Wherein, the response to the first slide operation in step 102 is to obtain the first track, and the specific implementation process is shown in Figure 2, including:

Step 201: Responding to the first sliding operation, taking j from 1 to N in sequence to obtain the jth position information of the jth touch point on the touch display unit of the first sliding operation, wherein, N is an integer greater than or equal to 2.

In a specific embodiment, if j is 1, the coordinates (X ₁ , Y ₁ ) of the first touch point on the touch display unit of the first sliding operation are obtained, which is the first touch point The position information of the control point, and so on, if j is N, then the coordinates (X _n , Y _n ) of the Nth touch point are the position information of the Nth touch point.

Step 202: Determine a j-th preset range based on the j-th position information, wherein an area of the j-th preset range is smaller than an area of the touch display unit.

In a specific embodiment, according to the jth location information, for example, the jth location information is a point whose coordinates are (X _j , Y _j ), and the jth preset range is determined. Wherein, the preset range can be set by itself, and can be a range surrounded by a square with a side length of 3 cm centered on the coordinate point (X _j , Y _j ), or can be surrounded by the coordinate point (X j , Y j ). _j , Y _j ) is the center of the circle and the range surrounded by a circle with a radius of 3cm. Since the determined area of the jth preset range is smaller than the area of the touch display unit, it solves the problem of large workload and time-consuming when scanning the touch display unit in full screen to identify touch points in the prior art. After a long time of technical problems, the technical effect of quickly detecting touch points has been realized.

After the jth preset range is determined, proceed to step 203: within the jth preset range, detect whether there is a j+1th position of the first sliding operation on the touch display unit touch points.

As shown in Figure 3, in a specific embodiment, step 203 includes:

Step 301: within the j th preset range, obtain P coordinate points in the coordinate system based on the X axis and the Y axis in the touch display unit, where P is an integer greater than or equal to 2.

In a specific embodiment, there are P points within the jth preset range of the touch display unit, and the P points are coordinate points in a coordinate system based on the X-axis and the Y-axis, wherein the Include at least two coordinate points within the preset range, for example, coordinate point (X _j , Y _j ) and coordinate point (X _j , Y _j+1 ), or coordinate point (X _j , Y _j ) and coordinate point ( X _j+1 , Y _j ).

After obtaining the P points, enter step 302: apply a driving voltage to the Y coordinate of each point in the P points, and then detect the induced voltage value received by the X coordinate corresponding to the Y coordinate of each point . Wherein, the driving voltage may be 4V or 4.3V.

After completing step 302, enter step 303: when the induced voltage value received by the X coordinate is smaller than the driving voltage, determine the point corresponding to the X coordinate as the j+1th touch point.

In a specific embodiment, if the received induced voltage value is 3.5V, which is less than the driving voltage 4V, then it is determined that the point corresponding to the X coordinate is the j+1th touch point.

After determining that the point corresponding to the X coordinate is the j+1th touch point, proceed to step 204: when the j+1th touch point exists and the j is N, sequentially connect the N+1 touch points to obtain the first track.

Through the implementation of steps 201-204, first, obtain the first touch point, and then use the first touch point as a reference point, within a preset range, by detecting the induced voltage value and comparing it with the driving voltage to obtain The second touch point, and so on to obtain the N+1th touch point, and finally connect the N+1 touch points to obtain the first track. Similarly, the second trajectory can be obtained.

After obtaining the first trajectory, enter step 103: take i from 1 to M in sequence, and judge the first induced voltage value of the i-th first point on the first trajectory and the value of the first induced voltage on the second trajectory Whether the size relationship between the second induced voltage value at the i-th second point and the third induced voltage value at the i-th third point satisfies the first preset condition, and M first judgment results are obtained, wherein the first The i third point is a point on the line between the ith first point and the ith second point, and M is an integer greater than or equal to 2.

In a specific embodiment, taking i from 1 to M in turn, first, obtain the i-th first point on the first track, and determine its induced voltage value as the first induced voltage value, and obtain the i-th point on the second track second point, and determine its induced voltage value as the second induced voltage value, obtain the i-th third point on the connection between the i-th first point and the i-th second point, and determine The induced voltage value is the third induced voltage value, and then, it is judged whether the third induced voltage value is greater than the first induced voltage value and the second induced voltage value, a judgment result is obtained, and it is determined to be the first induced voltage value. critical result. Since i ranges from 1 to M, after step 103 is completed, M first judgment results are obtained.

After step 103 is completed, go to step 104: judge whether the M first judgment results satisfy the second preset condition, and obtain the second judgment result.

In a specific embodiment, it is judged whether a preset percentage of the first judgment results of the M first judgment results satisfy that the third induced voltage value is greater than the first induced voltage value and the second induced voltage value, Wherein, the second preset condition is to limit that most of the third induced voltage values in the M first judgment results are greater than the first induced voltage value and the second induced voltage value, and the preset percentage can be hundreds 95 percent, or 90 percent.

After completing step 104, enter step 105: when the second judgment result shows that the M first judgment results satisfy the second preset condition, determine the M third points as invalid touch points. In a specific embodiment, if a preset percentage of the first judgment results among the M first judgment results satisfies that the third induced voltage value is greater than the first induced voltage value and the second induced voltage value , it is determined that the M third points are invalid touch points, and if not satisfied, it is determined that they are valid touch points. After determining that the M third points are invalid touch points, it may be determined that the i-th first point and the i-th second point are two independent touch points, and then on the touch display The first track corresponding to the first sliding operation and the second track corresponding to the second sliding operation are displayed on the unit. When the first trajectory and the second trajectory correspond to an output effect, the output effect is executed. For example, when using a tablet computer to play a piano game, when the first track corresponds to the do key and the second track corresponds to the mi key, since it is judged that the first track is different from the second track, the tablet is controlled The computer emits the sound of do and the sound of mi at the same time.

User A holds a tablet computer in his hand. When user A puts the index finger and middle finger of his right hand together, and slides from top to bottom on the touch screen of the tablet computer, the tablet computer gets the corresponding index finger and middle finger. The first trajectory and the second trajectory of the sliding operation, and obtain N points on the first trajectory and the second trajectory respectively, and the i-th first point on the first trajectory and the i-th point on the second trajectory The i-th third point on the connection line between the i second points, where i ranges from 1 to N in sequence.

Furthermore, by obtaining the first induced voltage value of the i-th first point on the first track, the second induced voltage value of the i-th second point on the second track, and the third induced voltage value of the i-th third point Voltage value, judging whether the third induced voltage value is greater than the first induced voltage value and the second induced voltage value, and obtaining the first judgment result, when taking i from 1 to M, if it is judged that M said Among the first judgment results, a preset percentage of the first judgment results satisfies the condition that the third induced voltage value is greater than the first induced voltage value and the second induced voltage value, then the M touch points are An invalid touch point means that it is determined that two different fingers of the user are operating on the touch display screen.
