Problems solved by technology

After the introduction of tactile feedback, especially electrostatic tactile feedback, the friction force during the interaction process between the finger and the touch screen is increased, which affects the corresponding interaction performance.

The existing research results of translational interaction efficiency under electrostatic force tactile feedback are only the results of simple statistical analysis of experimental data, and the theoretical analysis of data characteristics is not sufficient. Conclusion universality needs to be improved
