Embodiment Construction

[0027] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0028] An objective evaluation method for the realism of force-tactile reproduction based on the characteristics of human tactile perception proposed by the present invention is a simulation of the task process of human subjective perception and evaluation of force-tactile reproduction, as shown in the attached figure 1 As shown, both subjective and objective force tactile reproduction realistic evaluations include four basic steps of perception, conduction, classification, and evaluation, in which tactile receptors and physical sensors belong to the perception process, nerve conduction and data preprocessing belong to the conduction process, and the nerve center (brain ) and tactile perception model processing belong to the classification process, and the final result belongs to the evaluation process. Specific to the objective evaluation method fo...

Abstract

The invention discloses an objective evaluation method for the realistic sense of force tactile reproduction based on the characteristics of human tactile perception. The method simulates the process of human subjective evaluation of the sense of reality. The data is collected and analyzed to generate a multi-dimensional matrix, that is, "force tactile image". Through the modeling based on the characteristics of human tactile perception, the force tactile image is perceptually filtered to map the data to the perceptual space, and the data in the real and virtual environments are analyzed in the perceptual space. The similarity analysis is carried out to complete the objective evaluation of force-haptic realistic reproduction. The invention effectively avoids the influence of human subjective factors in the evaluation process, and has stability and repeatability; compared with the subjective evaluation experiments requiring multiple times and long periods of time, the invention has high efficiency and saves time. It fully considers the characteristics of human haptic perception, and is closer to the real evaluation process; it is suitable for different haptic reproduction devices and tasks.

Description

technical field [0001] The invention belongs to the field of force-tactile interaction, and in particular relates to an objective evaluation method for realistic sense of force-tactile reproduction based on the characteristics of human tactile perception. Background technique [0002] Virtual haptic reproduction is to use certain devices to simulate various mechanical stimuli in the interaction between people and the environment in the real environment and act on people, thereby generating a haptic experience process similar to the real environment. Force-tactile reproduction not only reflects the objective physical properties of objects in the environment, but also has a close relationship with human tactile perception characteristics. It is a vivid imitation and description of the similarity of objectively existing objects. [0003] Realistic haptic reproduction can improve the effectiveness of human-computer interaction and expand the practicality of virtual reality techn...
