Writing underlay that generates awakening effect

摘要

Power of concentration of a person at a study time usually declines with the passage of time. However, a practical and concrete method of actively providing a stimulus that makes the person less drowsy, that is, a device that realizes provision of a local exercise stimulus that vibrates a part of a human body, has not been developed. The invention provides an underlay that is used as a stationery product and that generates an awakening effect, the underlay having plural shapes of protrusions and indentations at an upper surface side of the underlay.
