VRによる視聴覚実験―VR HMDにおける刺激呈示の正確性・精度と留意点―

抄録

Virtual reality (VR) is a new methodology for psychological studies. Especially in modern VR head-mounted displays (HMDs), researchers can control more complex and dynamic stimulus presentation than in standard laboratory experiments, enhancing the ecological validity of research. While the studies by VR HMDs have increased, little is known about what are technical points to establish more stable VR environments and whether current VR HMDs have millisecond accuracy and precision for stimulus presentation compared to traditional laboratory environments, since most standard methods in psychological studies are not optimized for VR environments. Thus, the present article provides key features for setup of more reliable VR studies, introducing recent works that have revealed the time/timing accuracy and precision of visual and auditory stimulus presentation in modern VR HMDs.
