3D projection rendering method based on fused electrostatic force and vibro-tactile reproduction device

Abstract

The invention relates to a 3D projection rendering method based on fused electrostatic force and vibro-tactile reproduction device, and belongs to the field of virtual reality and human-computer interaction. The method comprises: acquiring depth information according to the depth image, and rendering a normal contour feeling by using vibration through an established psychological and physical model; and calculating gradient information according to the depth value, according to the established psychological and physical model and an IP0.625 conversion method, rendering the outline change of the tangential bulge through electrostatic force, and presenting the outline information through the 3D bulge rendering method based on the depth image. The mapping relation is established according tothe depth information of the depth image, finger tangential force and normal force can be rendered at the same time, and a more real three-dimensional tactile reproduction effect is achieved.

Description

technical field [0001] The invention belongs to the field of virtual reality and human-computer interaction, and in particular relates to a 3D projection rendering method based on a fusion electrostatic force and vibratory tactile reproduction device. Background technique [0002] Touch screens have been widely used in various commercial intelligent terminals such as mobile phones, tablet computers, TVs, and readers, and have become an indispensable part of our lives. However, people's interaction process with touch screens mainly relies on visual and auditory perception channels but lacks tactile perception channels, which leads to overload of visual and auditory channels and touch as an important human sense is not activated. Haptic feedback can improve the user's gesture interaction performance on the touch screen, and enhance the realism and richness of the user's interaction in Internet shopping, video games, and education and teaching. Touching the multimedia terminal...

Problems solved by technology

[0012] The present invention proposes a 3D projection rendering method based on the fusion of electrostatic force and vibration tactile reproduction device. Through the conversion method IP0.625 between the actual force curve and the tangential tactile feedback force, it solves the problem that the electrostatic force tactile feedback cannot provide lateral The problem of thrust, and the depth information is rendered normally through vibration haptic feedback, which improves the realism of 3D convex contour rendering
