It has two usage modes: teaching mode and online assessment mode. The teaching mode is used for training, while the online assessment mode enables exams in a computer environment via the internet. The assessment content covers six major modules, including the parts library, structural principles, disassembly and assembly training, maintenance training, fault handling, and electrical appliance assembly.

The teaching mode is for instructors to use during teaching and explanations. The content of the explanations can be projected onto a large screen via a projector for all students to view. Each detailed step can be executed one - by - one. Instructors can drag, drop, rotate the 3D models of various components before and after disassembly using the mouse.

In a three - dimensional virtual environment, assessment training is carried out. Questions in the assessment process are randomly selected to evaluate students' understanding and familiarity with the actual process operations. Practical assessments can be conducted on students regarding structural recognition, disassembly, assembly, maintenance, and process flows. The assessment process can record in real - time, provide error prompts, automatically collect answer sheets, and automatically grade, thus achieving standardized exams.
