A Design Method of Vibration Tactile Feedback Device Based on Cyber-Physical Interaction

Abstract

The invention discloses a design method of a vibratory tactile feedback device based on information-physical interaction. Some information of a virtual-real interaction system is fed back in a non-visual manner, that is, through a vibratory tactile feedback device, and coordinated with a visual feedback system. The vibration tactile feedback device can superimpose the collision feedback of the real object on the virtual object through vibration on the basis of the real tactile feedback of the hand, and simulate the collision interaction between the virtual object and the physical object, so that people can also perceive The contact and collision between physical objects and virtual objects produces a more realistic interactive experience and improves the multi-modal interaction between people and the AR environment and virtual objects. The multi-modal interaction combining vision and touch helps to expand the information feedback channel, enhance the coordination between people and the system, and enhance the seamless integration between participants, real environment and virtual environment under the cyber-physical fusion system. Realize natural and harmonious human-computer interaction.

Description

technical field [0001] The invention relates to the fields of intelligent manufacturing and ergonomics, in particular to a design method of a vibratory tactile feedback device based on information-physical interaction. Background technique [0002] The core of the cyber-physical fusion system is the real-time seamless connection and interaction between the virtual world and the physical world, in which augmented reality technology is the basis for virtual-real fusion display and interaction. Augmented reality (Augmented Reality, referred to as AR), is a technology that "seamlessly" integrates real world information and virtual world information. Sound, taste, touch, etc., are simulated and then superimposed on the real world, and are perceived by human senses, so as to achieve a sensory experience beyond reality. [0003] The current cyber-physical interaction technology mostly starts with the superposition and display of AR virtual visual information, and some researches h...

Problems solved by technology

[0007] Although this kind of fixed force feedback device can superimpose the tactile feedback of virtual and real collisions on the human hand, this kind of device usually has limited portability and inflexible operation

Moreover, this kind of tactile feedback cannot intuitively obtain the tactile perception when operating virtual objects, and lacks a realistic interactive experience.
