High-level user experience has become the key factor that one game can be successful in the\ngame market. The home page of mobile games, especially the design of the navigation interface, has a\nsignificant impact on usersâ?? initial experience, which is an important determent to usersâ?? preferences\nand purchase decision. Hence, measuring usersâ?? perceptual experiences of the navigation interface\ncan help designers understand real demands from users. Previous studies primarily used self-report\nscales or interviews to measure gamersâ?? perceptual experiences. However, it may not reflect gamersâ??\nreal perceptions that they are feeling as most of time the feeling is short-lived and implicit. To fill\nthis gap, the current study attempted to combine subjective evaluation with event-related potentials\n(ERP) to objectively measure gamersâ?? perceptual experience evoked by the navigation interface of the\nmobile game. The navigation interfaces of mobile games with low, medium, and high perceptual\nexperience were developed and the ERP experiment was conducted to detect the differences in usersâ??\nelectroencephalograph (EEG) components when subjects were exposed to the different design levels\nof navigation interface. The results showed that N1 reaction showed asymmetry in brain regions,\nand P2 and N2 showed symmetry, and relative to the navigation interface with low and medium\nperceptual experiences, the high level of navigation interface induced a larger amplitude of N2 in\nthe anterior scalp and P2 in the frontal scalp. These EEG components can, therefore, be regarded as\nsignificant indicators reflecting gamersâ?? perceptions of the navigation interface. The findings benefit\ngame companies of navigation interface designs.
