The Characteristics of Attention and Visual Fixation According to the Adaptation Duration ofParticipants in VR HMD

The first important sense that humans take is vision, and VR is a technology that uses such characteristics of humans to realize virtual reality that is similar to reality. This research is intended to be a study that can identify the characteristics of observation according to the immersive VR and the user's adaptive time. Results of HMD-based immersion VR line tracking experiments are as follows. First, there are five types of eye for subjects. Most subjects can see that the location of the start and end points is different from the location of the most viewed sites. After observing the 360° image for two minutes, we looked at the sum of the top two sections of the collected surveillance data with the highest values of fixing per subjects, and the subjects used HMD-based immersive VR. When observing a 360° image, focus most on the desired information, usually at a time of not less than 61 seconds and not more than 70 seconds after starting the experiment. The highest concentration of attention of the subjects from segment 7 and then lower from segment 8 and then higher from segment 12 again, were analyzed by viewing the characteristics of the watch type according to the time to be identified by the subjects. Based on this research, it is necessary to develop contents for virtual reality and to understand user characteristics according to immersive virtual reality.
