[Abstract]:Tactile reproduction technology is a hot topic in the field of human-computer interaction. It can be widely used in the fields of Internet, telemedicine, mobile shopping, education and teaching. The interaction of tactile reproduction technology can improve the quality and efficiency of human-computer interaction, give people more real immersion and open a new channel for communication between people and the virtual world. The tactile reproduction technology of force is one of the main ways to realize the nude finger tactile reproduction. The user can make use of the interactive interface of the smart phone with the tactile reproduction function of the bare finger touch, the tablet computer and other terminal interface, and can realistically and naturally perceive the physical properties of the shape, contour and texture of the virtual object, and realize the rich and realistic haptic reproduction. The key factor of the application of tactile reproduction technology is human tactile perception, and the formation mechanism of human touch is very complex. At present, the evaluation method of tactile effect mainly depends on the evaluation of the subjective feeling of the human body, lack of objective evaluation method and the evaluation data that can represent the effect of tactile reproduction. It has not yet formed quantified and standardized. In this paper, aiming at the evaluation of the effect of the tactile reproduction of static electric power, the evaluation method and evaluation are put forward from two aspects of quantitative and qualitative. It provides reference for improving the universality of tactile reproduction technology, making industry standards and expanding tactile interactive application. The main contents of this paper are as follows: (1) from the charge between the finger and the touch panel The mechanism of the tactile reproduction of static electric power is deeply analyzed, and the system equivalent circuit model of finger tactile panel is established by combining the electrical characteristics of the finger skin, and the static electric expression method of the tactile reproduction effect of static electric power is studied. (2) aiming at the objective evaluation of the effect of the static electric touch reproduction, the fingertip static electric power is formulated. The static electric power measurement device is designed and set up to measure the static electric power of the fingertip, and the simulation of the equivalent circuit model of the system is used to obtain the evaluation data that can accurately describe the realistic sense of the tactile power of static electric power, and the mapping model between the waveform of the fingertip static electric power, the frequency, the amplitude of the driving signal, the frequency and the amplitude. 3) make a subjective evaluation method based on the tactile reappearance effect of static electricity based on psychophysics, and take the subjective perception of human as the core, and test the threshold of amplitude perception, frequency resolution threshold and amplitude resolution threshold of human finger under the four waveforms of sine wave, square wave, sawtooth wave and triangle wave, and analyze the threshold of sex to each threshold by ANOVA analysis. The influence of the value, the hardness, viscosity, roughness and comfort of the static electric touch is evaluated, and the mapping mechanism model between the static electric power and the tactile is established in combination with the objective static electricity measurement data. (4) the subjective evaluation method of the tactile reappearance effect of static electric power based on the task performance is set up, and the ergonomics rule of the static electricity is introduced to -Steering Law, the experimenter explores the influence of the interactive mode of the tactile reappearance technology of the fusion of static electricity on the efficiency and accuracy of the touch screen interaction. The main innovative work of this paper is as follows: (1) the equivalent circuit model of the static electric tactile reproduction system is improved, and the indirect measurement of the fingertip static electric power is proposed. Method, a static electric measurement platform is set up to solve the problem of static electricity measurement. (2) in view of the objective evaluation of the effect of the tactile reproduction of static electric power, a mapping model between the driving signal waveform, frequency and amplitude parameters and static electricity is established. (3) based on the subjective evaluation of the effect of the tactile reproduction of static electric power, a psychophysics based on the psychophysics is formulated respectively. Based on the evaluation method of task performance, using the method of psychophysics, the tactile perception threshold of the human body is obtained. Using the task performance method, it is proved that the interactive mode of the tactile reproduction technology of the fusion static electric power can improve the interaction efficiency and the interaction accuracy of the touch screen interaction.
