determining the change of a first electric signal generated by a force sensing assembly in the touch pad assembly when the pressing operation acts on the touch pad assembly within a preset time;

determining the amount of change in the acting force generated by the pressing operation based on the change in the first electrical signal.

In an embodiment of the disclosure, the first electrical signal is used to represent a magnitude of an acting force acting on the touch pad, and includes: the magnitude of the applied force is determined by the magnitude of the first electrical signal. For example a first electrical signal a, for characterizing a first force of the acting force; the first electric signal B is used for representing a second force of the acting force; when the first electrical signal A is greater than the first electrical signal B, a first force representing the acting force is greater than a second force representing the acting force. Therefore, the amount of change in the acting force generated by the pressing operation can be determined by the change in the first electric signal.

In some embodiments, the vibration feedback assembly comprises at least one of:

linear motors, rotor motors, piezoelectric motors.

In the embodiment of the disclosure, for the detection of the pressing force degree, in order to improve the accuracy and the sensitivity of the detection of the pressure sensor and avoid the error touch and misoperation, the variation of the adopted force is compared when the acting force strength is judged. For example, when the force sensor detects the intensity data of the force, there is a high-speed sampling process, the sampling frequency range is 5Hz-100Hz (not limited to this range), the frequency of data collected by the force sensor will change according to the use situation, that is, when the user operates, the sampling frequency will be higher, and when the user does not operate the operation panel for a long time, the sampling frequency will be lower. When the user is operating, the force sensor will input real-time force data Ft, which varies over time, to the control unit IC. The control unit calculates a shorter fixed time period Δ t-t 2-t 1; the force variation Δ Ft is Ft2-Ft1, and the Δ Ft is compared with a force threshold to determine whether the pressing operation is performed. When a user presses, pressing habits of different users are different, and even factors such as external environment, long-term use of the operation panel and the like can bring errors. For example, when a user is using an object (for example, a pencil) that is just placed on the operation panel, the force applied to the operation panel by the object is Fw, and since the object does not cause a change in the touch sensor parameter, the IC determines the force as a non-user force. However, in this case, the real-time force data Ft sampled by the force sensor during the operation by the user may include the force Fw applied to the operation panel by the object, and if the force Ft sampled by the force sensor is used to directly determine whether the pressing may introduce an error, which may cause an error operation, the error force Fw may be exactly eliminated by changing the amount of the force Δ Ft to Ft2-Ft 1. Additionally, the user can make settings within the computer system whether multiple levels of pressing are required.

In the embodiment of the present disclosure, when it is determined that the pressing operation is the user operation, the control unit may feed back a touch signal or an electrical signal to the control system.

When it is determined that the pressing operation includes user operation and non-user operation, the strength of the acting force generated by the user operation can be obtained by subtracting the strength of the acting force generated by the non-user operation from the total strength of the detected acting force. For example, in the first duration, it is determined that the pressing operation is a non-user operation, the force detected as the acting force is the first detection force, in the second duration, it is determined that the pressing operation is a user operation, the force detected as the acting force is the second detection force, and at this time, it is determined that the force of the acting force corresponding to the user operation is the force value obtained by subtracting the first detection force from the second detection force.
