66-3: Aftereffect of Viewing Concave Curved Displays in Large and Wide-angle Environment: Assessment of Individual Differences

Abstract

Relationship between stabilometry performance and the individual differences in curved-surface-aftereffect (CS-AE) is investigated. Subjects with a rigid perception of CS-AE, approximately half of all, are able to well integrate visual and gravity sensory systems, suggesting that the CS-AE mechanism has some essential role in acquiring multimodal information.

P‐32: Aftereffect of Viewing Concave Curved Displays: Assessment of Individual Differences in Equilibrioception Performance and Effects of Viewing Angle

“…Generally speaking, results were broadly similar to those of our previous report [5]. Therefore, we summarize the key points below.…”

“…In 2015, we found the curved-surface-aftereffect (CS-AE), and demonstrated clear individual differences when observing a large-size simulated curved display as shown in Figure 1 [4]. We also investigated the relationship between CS-AE and stabilometry (i.e., sway of center of pressure/gravity) and clarified why clear individual differences exist [5].…”

“…The two experiments shown in Figure 2 were conducted without a break in order to obtain more significant data than was gained in [5]. Changes in CS-AE duration were investigated in Experiments 1 and 2.…”

“…Changes in CS-AE duration were investigated in Experiments 1 and 2. Measurement method was the same as that in the previous study [4] [5]. Also, changes of stabilometry over short periods (Experiment 1) and long periods (Experiment 2) are investigated.…”

“…Fifty observers, who were undergraduate or graduate students, aged from 19 to 24, participated in Experiments 1 and 2; the number of newly added observers from the previous report [5] was twenty-seven. All reported normal or corrected-to-normal vision.…”
