Table 4: The results of the differences in the mechanics of three conditions among the three ADHD subtypes of participants. Combined subtype (N = 17); hyperactive–impulsive subtype (N = 2); inattentive subtype (N = 6). Figure 3: Results of specific questions about the mechanics of each condition (N = 25). Table 5 shows the percentages of participants' experiences with Social VR. All participants were satisfied with the use of Social VR, including a high level of enjoyment, willingness to repeat, feeling real, and good visual and auditory effects. Regarding motion sickness, no participants reported dizziness and discomfort during and after playing Social VR. \begin{table}
