Abstract

The invention discloses a mobile terminal orientated frictional force tactile sense reappearing system and reappearing method. The system comprises a mobile terminal, a frictional force tactile sense driving module and a tactile sense panel, wherein the frictional force tactile sense driving module comprises an MCU, a piezoelectric ceramic sheet drive signal generation module and a power supply module. By virtue of the system, when a finger tip of an operator moves on the tactile sense panel, the mobile terminal can detect the position of the finger tip on the tactile sense panel in real time and transmit a gray value of a point corresponding to the position to the MCU through a USB; the MCU controls the signal amplitude generated by a function signal generator according to the gray value, and then through amplification by an audio power amplifier, a sine wave signal with adjustable amplitude can be obtained; and the signal can change the frictional force coefficient on the tactile sense panel, and when the finger of the operator slides, the finger tip can feel the frictional force change on the tactile sense panel. The mobile terminal orientated frictional force tactile sense reappearing system can be applied to a man-machine interaction system used for tactile sense reappearing, and is convenient to operate and strong in experience.

Description

technical field [0001] The invention relates to the field of tactile reproduction human-computer interaction, in particular to a mobile terminal-oriented friction tactile reproduction system and reproduction method. Background technique [0002] In the next few decades, two technologies, virtual reality and artificial intelligence, will open a "gateway to hyper-reality" for the scientific community and lead the next wave of technological change. As an important technology in the field of human-computer interaction, tactile reproduction technology can be predicted to occupy an important position in the realization of virtual reality and artificial intelligence, and will have a profound impact on people's information exchange and communication methods. At present, the more common tactile reproduction technologies can be divided into: vibration-based tactile reproduction, force feedback-based tactile reproduction, array-based tactile reproduction, gas pressure-based tactile rep...
