A vibration tactile feedback device design method based on information physical interaction

Abstract

The invention discloses a vibration tactile feedback device design method based on information physical interaction, which is characterized in that some information of a virtual-real interaction system is fed back in a non-visual mode, namely a vibration tactile feedback device, and the vibration tactile feedback device is coordinated with a visual feedback system. According to the vibration tactile feedback device, on the basis of real tactile feedback of the hand and through vibration superposition of collision feedback of a real object to a virtual object, collision interaction between thevirtual object and a physical object is simulated, so that a person can sense contact collision between the real object and the virtual object in a virtual-real fusion environment, more real interaction experience is generated, and multi-mode interaction between the person and an AR environment and between the person and the virtual object is improved. The visual and tactile combined multi-mode interaction is helpful for expanding an information feedback channel, improving the coordination of people and a system, enhancing the seamless fusion among participants, a real environment and a virtual environment in an information physical fusion system, and realizing natural harmonious man-machine 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.
