Testing the time to complete the collection sample task or tires repairing task

We will have 5-30 people based on the available sample to complete the task using paired (or two) sample t-test with random order on the same task

• With App's instruction help time (wearing or by looking at the simulation video) and task % of completion

• Without App's instruction time and task % of completion

• A Survey on the feedback on UI comfortable, visible, error, blocking and smooth of the App's flow

Provide a platform for vital equipment analysis

• The graph analysis
