Menu optimization of digital twin system based on user experience: A case study of lyophilized injection workshop

Abstract: Menus are not only a basic user interface element in digital twin systems, but also a key component to improve system usability, user experience, and operational security. Pie menus have been used in SunView, NEWS, and many other systems since Hopkins pioneered them, but they are not widely used in digital twin systems. Previous studies have shown that its usage efficiency is better than that of linear menus, so this paper takes the lyophilized injection workshop digital twin system as an example to verify the user experience differences between pie menus and linear menus within the digital twin system. According to the function of the production line in the lyophilized powder production workshop, the pie menu and linear menu are designed for the interface of the cartoning robotic arm equipment in the intelligent packaging line, and the usability test is used to quantify the user experience data, and through the reliability and validity test and data analysis, it is concluded that the pie menu is higher than the linear menu in terms of ease of learning, use efficiency, usability, and satisfaction, etc., and that the adoption of the pie menu can help to improve user experience.
