A texture tactile reproduction device, a display device and a radian reproduction device

Abstract

The invention relates to a texture haptic reproducing device. The display device and the radian reproducing device are respectively provided with two rows of piezoelectric ceramics at two ends of a conductive surface of a touch panel. Based on the squeeze film effect, the finger can touch the interface surface dynamically by changing the friction force between the finger and the contact surface and reproducing the surface texture information of the virtual object in the form of variable friction force, which is the closest natural detection method. The invention improves the piezoelectric ceramic matrix of the prior art, realizes texture reproduction by using two rows of piezoelectric ceramics, makes the device lighter and thinner, increases effective touch area greatly, can be integratedwith common electronic products on the market, and has strong practicability. The texture tactile reproducing device can be integrated on the display screen of the electronic product, and the tactilefeedback function of the electronic product is added. The operator can perceive the surface texture information of the virtual object in the form of variable friction force, thereby enhancing the sense of reality and immersion of the virtual environment.

Description

technical field [0001] The present invention relates to texture reproduction technology, more specifically, to a texture tactile reproduction device, a texture tactile reproduction display device, and a texture tactile reproduction radian reproduction device. Background technique [0002] Traditionally, people often use vision and hearing for human-computer interaction, while often ignoring the role of touch. Although less than 2% of the information obtained by humans comes from touch, its role is indispensable, especially in distinguishing substances. material properties. Therefore, in order to enhance the immersion during human-computer interaction, multi-sensory mode fusion can be adopted, and the latest technology is tactile interaction. The tactile interaction technology mainly enables the operator to perceive rich environmental information such as the shape, hardness, and texture of virtual objects in the form of motion or force, thereby enhancing the sense of reality...

AI Technical Summary

Problems solved by technology

The advantage of this method is that it is simple and easy to control, but there are two problems at the same time: one is that it is difficult to reproduce the micron-scale texture, which is related to the thickness and distribution density of the needles; is because the amplitude range of the needle is usually small

The disadvantage of this method is that there is a thin film between the finger and the surface of the device interface, which is an indirect contact, which reduces the operator's sense of immersion
