Touch pressure vibration feedback device and driving method

Abstract

The invention relates to a touch pressure vibration feedback device. The device comprises a micro-controller, a pressure sensor module and a vibration feedback module connected with the micro-controller, the micro-controller comprises a detection module, a calculation module and an AD conversion module, the vibration feedback module is used for receiving the vibration intensity corresponding to the command feedback of the detection module. The touch pressure vibration feedback driving method comprises the steps that the touch pressure operations on a terminal by the users are received, the values of the pressure signals are computed according to the tiny deformation quantity of the touch pressure device, the intensity of the corresponding vibration feedback is determined based on the values of the pressure signal. Thus the users through the touch pressure operations acted on the terminal provide feedbacks on the vibration effects of different intensities, so that the users have an intuitive quantitative cognition of the magnitude of their touch pressures, on the one hand the users can understand and improve their own touch operations, on the other hand the users can also build a touch pressure quantification system based on the user behaviors, and the device has a good interactive effect.

Description

technical field [0001] The invention belongs to the technical field of terminals, and in particular relates to a pressure touch vibration feedback device and a driving method thereof. Background technique [0002] Pressure touch technology refers to the addition of a third dimension on the basis of the plane operation of existing touch products, that is, to sense the pressure of pressing, and to perform three-dimensional action feedback of light tap, light press, and heavy press. In this way, touch interaction can be extended from the "time" dimension of long press to the "strength" dimension of heavy pressure, opening up a new space for human-computer interaction and realizing different applications. The biggest change brought about by pressure touch is to make the operation of touch products easier. Through the multiple tiny electrodes around the touch product, it can sense the user's light touch, heavy touch and other operations, and different operation reactions can be r...

AI Technical Summary

Problems solved by technology

Usually users do not understand the pressing force and touch feedback, and it is easy to cause misoperation due to inappropriate pressing force

In addition, in actual operation, the user operates with his usual pressure. If there is no need to issue a pressure touch at this time, since the user does not understand the feedback results of the pressure touch, it will also cause misoperation.
