Abstract: A temperature stimulus presentation device 1 includes a presentation unit 11 that generates heat at a predetermined temperature, and a control unit 12 that changes an area of the presentation unit 11 depending on whether or not a temperature stimulus is presented.

Abstract: A presentation device includes a stimulation presentation unit that presents temperature stimulation at a predetermined temperature and a temperature control unit that sets the temperature of the stimulation presentation unit. The stimulation presentation unit has a size that causes a person to feel temperature stimulation when the stimulation presentation unit touches a first portion and the person not to feel the temperature stimulation when the stimulation presentation unit touches a second portion that is less perceptible than the first portion. The temperature control unit sets the temperature of the stimulation presentation unit so that the stimulation presentation unit presents pain due to temperature stimulation when the stimulation presentation unit touches the first portion and does not present the pain due to temperature stimulation even when the stimulation presentation unit touches the second portion.

Abstract: A stimulus presentation device 13 that stimulates a user with air from a plurality of air guns 14 arranged so as to surround the user includes a control unit 132 that determines respective ejection times at which a plurality of air streams are to be ejected at given time intervals which allow the user to perceive an apparent motion as well as respective ejection azimuth directions in which the plurality of air streams are to be ejected and causes the air streams to be sequentially ejected from the respective air guns 14 disposed in the individual ejection azimuth directions at the individual ejection times and an adjustment unit that determines a plurality of different body sites on a body of the user to which the plurality of air streams are to be applied and adjusts respective ejection angles of the individual air guns 14 such that respective muzzles of the air guns 14 are pointed at the plurality of body sites.

Abstract: A thermal stimulus presentation device 1 for presenting a thermal stimulus in the mouth includes a presentation unit 13 that presents the thermal stimulus in the mouth, a receiving unit 11 that receives notification information for notifying a user, and a control unit 12 that controls the thermal stimulus of the presentation unit 13, upon the notification information being received, the presentation unit 13 presenting the thermal stimulus in the mouth in accordance with the control of the control unit 11.

Abstract: A reliable technology for determining the masticatory side of the user based on the surface myoelectric potential of masticatory muscles is provided.

Abstract: A pseudo-food texture presentation device includes: an enclosure body in which a granular material is enclosed; a measurer configured to measure at least one index among a temperature of an ambient environment of the enclosure body, a humidity of the ambient environment of the enclosure body, a temperature of the enclosure body, and a moisture amount on a surface of the enclosure body; and an enclosure body controller configured to control density of the granular material inside the enclosure body in accordance with the measured index.

Abstract: The number n of times of chewing is counted by chewing number of times calculation means (13b2) based on a change in the distance l from a photorefiector (50), which is received together with time t by measurement value receiving means (13b1). To vary hardness h of a bag (30) to a stage that can be sensed, according to the number n of times of chewing, a required air pressure is set according to the current number n of times, based on a hardness/air pressure correspondence recording unit (13g) in which stages that have a significant difference therebetween and are stored in association with the number n of times of chewing are recorded. To realize the set air pressure inside the bag (30), the amount of sucking performed using a vacuum pump 20 is controlled by air pressure control means (13b4).

Abstract: An aerial image display device is capable of changing a depth of a virtual image viewed by an observer without changing a distance between at least one display device and an optical element forming the virtual image. The aerial image display device includes a display device, optical elements, and a reflecting member. The optical elements are installed corresponding to different display regions of a display surface of the display device and sequentially arranged along the display surface in an observation direction of an observer. The optical element is installed obliquely with an angle of about 45° in a ?X direction when viewed from the display surface of the display device. The optical element is installed obliquely with an angle of about 45° in an X direction when viewed from the display surface of the display device.
