The field of view (FoV) is one of the main properties of virtual reality (VR) systems with head-mounted displays (HMDs). While preceding VR studies have suggested novel methodologies to extend the FoV of HMDs, there were limitations in those methods, including: heavy weight, high cost, and screen distortion. The observation through the human retina indicated that the density of human photoreceptors are distributed variedly between the central and peripheral visual fields. The sparse peripheral display (SPD) was proposed based on these observations. In this study, we suggest and compare the combination of SPD technologies using different number (2-80) of light-emitting diodes (LEDs) and different tasks (visual search and emotion tasks). The results showed that the visual-search task with use of six LEDs and there were no significant differences in the emotion task. Discussion of the potential applications of SPD-HMD systems, including therapeutic techniques to assist handicapped people was done.
