Quantitative evaluation method for realism of tactile reproduction contour rendering based on feature similarity

Abstract

The invention relates to a method for quantitatively evaluating realism of tactile reproduction outline rendering based on feature similarity, and belongs to the field of human-computer interaction. Perceive and record the real object perception experiment data and construct matrix by using the real contour, use the tactile feedback device to render the real contour, perceive and record the perception experiment data of the virtual object and construct the matrix, and then use the principal component analysis method to obtain its main features Vector, by calculating the similarity of the main eigenvectors to realize the quantitative evaluation of the realism of the tactile reproduction outline rendering, which can be used for the quantitative evaluation of the realism of the 3D sinusoidal convex rendering based on the electrostatic force haptic feedback device. The invention can realize the quantitative evaluation of virtual object rendering realism based on the tactile reproduction device, and objectively evaluates the rendering realism starting from the physical properties and force changes of the object, and is not easily affected by factors such as environment and user psychology.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a method for quantitatively evaluating realism of tactile reproduction outline rendering based on feature similarity. Background technique [0002] The way of human-computer interaction mainly relies on the visual and auditory channels. The tactile reproduction technology opens up a new channel for human-computer interaction. The fusion of tactile reproduction and the other two modes can enable users to obtain a stronger sense of rendering realism and Immersion improves the quality and efficiency of human-computer interaction. Tactile reproduction technology has become one of the hotspots of human-computer interaction and can be widely used in education, teaching, medical care, game entertainment, online shopping and other industries. [0003] At present, according to the research progress of tactile reproduction devices at home and abroad, tactile reproduct...
