Head-mounted displays (HMD) have a variety of features that differ from those of conventional devices, and these features enable a more realistic experience. However, the effects of the unique features of HMD on human perception are still unknown. In this study, we examined the effects of synchronizing Fielf of view and head movement with auditory stimulus Localization on discrimination in VR. In the experiment, participants were asked to discriminate spherical motion (stream/bounce) in VR. The results showed that synchronization of visual field and head movement enhanced discrimination sensitivity and that the presentation of auditory stimulus altered the perception of spherical motion, but its positional information does not affect the perception of spherical motion. Synchronization between visual field and head movement was found to compensate for motion-induced blurring during discrimination and to improve discrimination sensitivity but did not affect the level of judgment.

With the aim of protecting the global environment and diversifying energy sources, the adoption of wind energy has surged worldwide, leading to an increased visibility of large-scale wind turbine generators. To garner positive public acceptance of wind turbines, careful consideration of social acceptability is crucial. This study focuses on the nacelle, the only component whose aesthetic shape design can be refined during the turbine’s design phase, among various factors influencing wind turbine shape. Utilizing the Semantic Differential （SD） method, we conducted a survey to investigate how observers perceive the shape of the nacelle. The results indicate a preference for nacelle shapes that blend with nature, such as an egg-shaped or gently curved design.

Obstructed paths often provoke anger among drivers, leading to aggressive behaviors and accidents. Effectively managing this anger is crucial for ensuring road safety. Despite the necessity of developing methods to induce driving-related anger, there is currently no established approach. This study examined whether encountering a roadblock set by another driver leads to increased anger and aggression during a driving game. The results indicate that scores on the state anger scale, indicative of heightened aggression, increased following the encounter with the roadblock. Additionally, we examined whether heightened aggression, reflected by left-dominant frontal activity, is observed during the driving. However, the observed brain activity suggests an avoidance motivation regarding driving challenges, regardless of the presence of the roadblock. This study underscores the ability of the driving game to evoke subjective anger during simulated driving experiences.
