Tactile feedback device based on touch screen multi-point vibration mode, and control method thereof

Abstract

The invention discloses a tactile feedback device based on a touch screen multi-point vibration mode, and a control method thereof. The device comprises a power supply circuit, a control circuit, n pieces of motor driving circuits, a touch screen and n pieces of vibration motors, wherein n is a natural number which is greater than 1; the power supply circuit independently supplies power to the control circuit, the motor driving circuits and the touch screen; the control circuit is independently connected with the motor driving circuits and the touch screen; and the vibration motor is placed onthe back surface of the touch screen and is correspondingly connected with the motor driving circuits. The device has the advantages of simple structure and convenience in operation, the vibration ofa plurality of vibration motors on the back of the touch screen is overlapped to control the touch screen to vibrate, various vibration ways can be obtained, and a true sense of touch is obtained according to different finger tip motion ways.

Description

technical field [0001] The invention relates to tactile feedback technology, in particular to a tactile feedback device based on a multi-point vibration mode of a touch screen and a control method thereof. Background technique [0002] At present, the scene reconstruction of virtual reality and augmented reality mainly revolves around people's visual and auditory senses, lacking information feedback and interaction in higher dimensions. With the development of technologies such as multi-person interaction and human-computer interaction, the demand for tactile perception is increasing day by day. Haptic feedback technology builds a bridge for the mechanical interaction between virtual objects and people, which can make the interaction between people and virtual environment more natural. [0003] In our daily life, tactile feedback is widely used in touch screens such as mobile phones, tablets, and cameras, bringing us a new user experience and fun. Haptic feedback is import...
