Haptic representation sense of reality objective evaluation method based on human haptic perception feature

Abstract

The invention discloses a haptic representation sense of reality objective evaluation method based on a human haptic perception feature. The method simulates a sense of reality evaluation process subjectively carried out by a person. The method is characterized in that first of all, data acquisition is performed on the same haptic representation task in a realistic environment and a virtual environment, a multidimensional matrix, i.e., a "haptic image", is generated through analysis, through modeling based on the human haptic perception feature, perception filtering is performed on the haptic image, data is mapped to a perception space, similarity analysis is performed on the data in the realistic environment and the virtual environment in the perception space, and thus objective evaluation of haptic sense of reality representation is completed. According to the invention, the method has the following advantages: influences exerted by human subjective factors in an evaluation process are effectively avoided, and the stability and the repeatability are high; compared to a conventional subjective evaluation experiment requiring many people and long time, the efficiency is high, and time is saved; the human haptic perception feature is taken into full consideration, and the process is closer to a real evaluation process; and the method is suitable for different haptic representation 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...
