Abstract
A wakefulness-maintenance apparatus applies a stimulus, which is not perceived to be unpleasant to most seated persons, to a seated person, and effectively maintaining the wakefulness of the seated person. After a control device provided to the wakefulness-maintenance apparatus stimulates the seated person using a first stimulus at a timing close to a human heartbeat, if an index showing the wakefulness of the seated person departs within a predetermined time from a standard indicating that the wakefulness has been maintained, the control device drives a stimulus device to stimulate the seated person using a second stimulus having a timing that differs from the first stimulus.
