Abstract

The invention relates to an optimal driving voltage selection method taking translation interaction efficiency as an index, and belongs to the field of human-computer interaction. An electrostatic force tactile feedback device is used; translation gesture interaction efficiency experimental data under two conditions of electrostatic force tactile feedback and electrostatic force tactile feedback are obtained, and a matrix is constructed; A kernel principal component analysis method is used for calculating a kernel matrix and obtaining corresponding kernel feature spaces, quantitative evaluation of the influence of electrostatic force tactile feedback on translation interaction efficiency is achieved by calculating the distance between the two kernel feature spaces, and the method is used for selecting the optimal driving voltage of the electrostatic force feedback device with the translation interaction efficiency as an index. The influence degree of electrostatic force tactile feedback on translation interaction efficiency can be quantitatively evaluated, the data theory is fully analyzed, and the obtained conclusion is high in universality; The method can also be expanded to quantitative evaluation of the influence of different electrostatic force touch driving modes on the gesture interaction performance, and is easy to popularize and apply.

Description

technical field

[0001] The invention belongs to the field of human-computer interaction, and in particular relates to an optimal driving voltage selection method with translational interaction efficiency as an index. Background technique

[0002] Smartphones and tablet computers with tactile reproduction functions have broad application prospects in medical and health care, e-commerce, education and entertainment, and visually impaired people. Through the tactile reproduction technology, on the one hand, the shape, texture and flexibility of the displayed object can be perceived by touching the screen of the multimedia terminal with bare fingers; It greatly improves the realism of the interactive process and the richness of the interactive experience. According to the different implementation principles, the existing tactile reproduction methods of multimedia terminals mainly include vibration, electrostatic force and air pressure film. Among them, the electrostatic force h...
