Stereoscopic Visuospatial Training and the Design of Exercise Intensity for the Ciliary Muscle Group

抄録

This study evaluated stereopsis during stereoscopic video viewing and examined the effects of repeated visuospatial training on visual and neural functions. In Experiment 1, latency to stereopsis ranged from instantaneous to 3 min: about half of the participants achieved stereopsis within 15 s, while the remaining participants required longer, with 44.8% unable to achieve stereopsis within the 3-min window (defined as non-visible). In Experiment 2, short-term improvements in visual acuity and peripheral recognition were observed following daily 3-min training sessions, whereas sustained improvements required 6-min sessions. Training also increased β–γ band activity in the brain wave during arithmetic tasks, suggesting enhanced attentional resources. These findings underscore the importance of optimizing exercise intensity for the ciliary muscle group and support the potential applications of such training in educational and geriatric care contexts.
