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

Temperature stimulus presentation apparatus and method

A thermal stimulus presentation devicefor presenting a thermal stimulus in the mouth includes a presentation unitthat presents the thermal stimulus in the mouth, a receiving unitthat receives notification information for notifying a user, and a control unitthat controls the thermal stimulus of the presentation unit, upon the notification information being received, the presentation unitpresenting the thermal stimulus in the mouth in accordance with the control of the control unit

Temperature stimulus presentation device and temperature stimulus presentation method

A stimulus presentation devicethat stimulates a user with air from a plurality of air gunsarranged so as to surround the user includes a control unitthat 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 gunsdisposed 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 gunssuch that respective muzzles of the air gunsare pointed at the plurality of body sites.

The number n of times of chewing is counted by chewing number of times calculation means () based on a change in the distance l from a photoreflector (), which is received together with time t by measurement value receiving means (). To vary hardness h of a bag () 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 () 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 (), the amount of sucking performed using a vacuum pumpis controlled by air pressure control means ().

Pseudo food texture presentation device, pseudo food texture presentation method, and program

A reliable technology for determining the masticatory side of the user is provided. First and second electromyographic waveforms respectively originating from left and right muscles related to masticatory actions of a user are acquired; a coefficient of correlation between pieces of information respectively extracted from the first and the second electromyographic waveforms is calculated as a first feature value; a second feature value is calculated from a power spectrum obtained by performing frequency analysis on the first electromyographic waveform; a third feature value is calculated from a power spectrum obtained by performing frequency analysis on the second electromyographic waveform; a learning model is generated by associating the first, second, and third feature values with a plurality of labels; and the masticatory side of the user is determined based on first, second, and third feature values calculated from a newly acquired electromyographic waveform and the learning model.

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&#xb0; in a &#x2212;X direction when viewed from the display surface of the display device.
