Usability evaluation of different interaction modes based on washing machine controlled area

Abstract

Background With the increasing number of information on the man-machine interface of washing machines in a limited area, constructing the usability evaluation index system based on different interaction modes will improve the product development. Methods The documentary survey and user research methods were used to construct the usability evaluation model of washing machine products. Through the scenario simulation experiment, the usability under the three interactive modes of buttons, buttons plus knob and touch screens is evaluated and analyzed. Conclusion In the limited operation area, when the information number is lower than 14, the user experience of three interactive modes is similar. As the number of information increases, the task success rate of the button plus knob interaction mode is better than the other two, and the interactive mode of the touch screen is superior to the buttons and buttons plus knobs in terms of efficiency, usefulness and satisfaction.
