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

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).
