Especially in the case where the object is turned (such as a racing game), it is possible to control the object to make a fixed angle of turning, which reduces the error of the turning angle. The first predetermined offset angle may be a preset maximum offset angle, | the pressure difference of the pressures on the two other contacts, ie the absolute value of the pressure difference of the pressures on the two other contacts, for example, a car The maximum offset angle of the steering may be 45 degrees, and the pressure values on the two other contacts are X1 and X2, respectively, and the first predetermined offset angle = 45×(|X1-X2|÷Max[X1, X2] ).

The pressure difference between the left and right contacts can determine whether the aircraft body is tilted to the left or to the right. . The four contacts may be paired in the form of a rectangular diagonal, and the two contacts on the diagonal form a pair, or may be paired by other means.

Optionally, when the number of the two or more contacts is four, determining the motion parameter of the object according to at least one of the position information of the two or more contacts and the pressure value of the pressing force comprises: following The positional relationship of the four contacts performs two sets of two pairs of contacts, and determines a pair of main contacts from the two pairs of contacts; determining the pressure according to the pressure value and position information of the pressure on the main contact The direction of movement of the object.

In this embodiment, a pair of main touch points are determined by comparing the sum of the pressure values of the two pairs of contacts, and the rotation direction of the object is determined according to the pressure values of the two touch points in the main touch point. For example, when the sum of the pressure values of the last two contacts is greater than the sum of the pressure values of the left and right contacts, the two touch points are determined as a pair of main touch points, if the pressure value of the front contact is greater than the rear contact The pressure value of the object is forward tilting. If the control head is lifted and the pressure value of the current contact is less than the pressure value of the rear contact, the rotation direction of the object is backward, such as the control head. reduce. Determine the rotation of the object based on the left and right contacts The direction is similar to the contact according to the direction of the two front and rear contacts.

In this embodiment, when determining the direction of motion, the sum of the pressure values of the current two contacts may be greater than the sum of the pressure values of the two contacts, and the pressure value of the front contact is greater than the pressure of the rear contact. The ray is made by the rear contact to the front contact, and the direction of the ray is taken as the moving direction of the object, that is, the main direction of motion of the object.

Optionally, after determining the moving direction of the object according to the pressure value and the position information of the pressure of the main contact, the method further includes:

For example, in the process of controlling the movement of the aircraft, the contact of the nose is the front contact, the contact at the tail is the rear contact, and the front and rear contacts are a pair of main contacts, and the pressure of the current contact is greater than the rear contact. When the pressure is applied, the front contact is the first contact, which is located at the head, and the control head is lowered. When the pressure of the current contact is less than the pressure of the rear contact, the rear contact is the first contact and is located at the tail. At the same time, the control head is raised, that is, the tail is lowered, and the direction of rotation can be referred to FIG.

In this embodiment, when the pressure difference between the pressure on the first contact and the second contact is not greater than a predetermined threshold, the calculation of the rotation angle is not performed to avoid erroneous operation. For example, the predetermined rotation angle of the aircraft in one direction is 90 degrees, the pressure value of the pressure on the first contact and the pressure value of the pressure on the second contact are Y1 and Y2, respectively, and the calculation formula of the rotation angle = 90 ×(|Y1-Y2|÷Max[Y1, Y2]), increases the accuracy of the rotation direction of the object.

Optionally, after determining the moving direction of the object according to the pressure value and the position information of the pressure of the main contact, the method may further include: pressing the pressure according to the pressure on the two other contacts and the two other touches The pressure difference of the pressure at the point adjusts the moving direction of the object, wherein the other contact is a contact other than the main contact among the four contacts.

Alternatively, adjusting the moving direction of the object according to the pressure value of the pressure on the two other contacts and the pressure difference between the pressures on the two other contacts may include: determining the moving direction of the object by the following formula Second offset angle: second offset angle=second predetermined offset angle×(|pressure difference of pressure on two other above-mentioned other contacts|÷pressure value of maximum pressure on two other above-mentioned contacts); The moving direction of the object is adjusted according to the second offset angle described above.

In this embodiment, after determining the main direction of motion of the object, in order to more accurately determine the pair The direction of motion of the image can be fine-tuned to the main direction of motion of the object. For example, the rotation of the fixed angle of the aircraft can be achieved, and the accuracy of the motion direction of the three-dimensional object is improved.

Alternatively, adjusting the direction of motion of the object based on the pressure value of the pressure on the two other contacts and the pressure difference between the pressures on the two other contacts may include determining the pressure on the two other contacts In the case where the pressure difference exceeds the second predetermined threshold, the direction of motion of the object is adjusted based on the pressure value of the pressure on the two other contacts and the pressure difference between the pressures on the two other contacts.

Determining whether the pressure difference of the pair of contacts (ie, two other contacts except the above main contacts) exceeds a second predetermined threshold (the second predetermined threshold may be a set fixed value, or may be based on the control The object type or different application scenarios are set in real time), when the pressure difference between the two other contacts exceeds the second predetermined threshold, the movement direction of the object is adjusted, when the pressure difference between the two other contacts is not When the second predetermined threshold is exceeded, the direction of motion of the object is not adjusted. It can avoid unnecessary misoperation and improve the accuracy of the object's moving direction.

Optionally, after determining the motion parameter of the object according to at least one of the position information of the two or more contacts and the pressure value of the pressing force, the method further includes: controlling the object to perform according to the determined motion parameter. motion.
