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 photoreflector (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: A message generation device according to an embodiment includes: a communicator information acquisition unit that acquires communicator information for estimating the emotion of a communicator; a receiver information acquisition unit that acquires receiver information for estimating the emotion of a receiver who is to receive a message from the communicator; and a message generation unit that generates a message indicating an activity that corresponds to the emotion of the communicator that was estimated based on the communicator information acquired by the communicator information acquisition unit. If the emotion of the communicator estimated based on the communicator information acquired by the communicator information acquisition unit is similar to the emotion of the receiver estimated based on the receiver information acquired by the receiver information acquisition unit, the message generation unit generates a message that specifically indicates the activity, as the message indicating the activity.

Abstract: A psychological oppression feeling that is given to a person by a robot is accurately calculated. There is provided a psychological oppression feeling calculating device including: a first acquisition unit (S02) that acquires a relative positional relationship between a person and a plurality of robots including the number of the plurality of robots with respect to the person, a moving speed of the robot, and a distance between the person and the robot; a second acquisition unit (S01) that acquires a density of the robots with respect to the person; and a calculation unit (S03 and S04) that calculates a psychological oppression feeling given to the person by the robots from results acquired by the first acquisition unit and the second acquisition unit.

Abstract: A message selection device according to an embodiment includes a message database that holds a plurality of messages in correspondence with each of various emotion of a communicator, a communicator information acquisition unit configured to acquire communicator information for estimating the emotion of the communicator, a receiver information acquisition unit that acquires receiver information for estimating the emotion of a receiver who is to receive a message from the communicator, and a message selection unit that estimates the emotion of the communicator based on the communicator information acquired by the communicator information acquisition unit, estimates the emotion of the receiver based on the receiver information acquired by the receiver information acquisition unit, and selects a message from among the messages held by the message database based on the estimated emotions.

Abstract: A larger number of emotions are expressed by a contact stimulus. An input unit into which a type of an emotion and a degree of a strength of the emotion are input, and a calculation unit that calculates a presentation pattern of a contact stimulus and a degree of a strength of the contact stimulus in accordance with content input into the input unit are included.

Abstract: A technology for simulating physiological activity more appropriately is provided. An optimization apparatus according to an embodiment includes an estimation unit, a first calculation unit, a second calculation unit, and an updating unit. The estimation unit estimates a physiological parameter indicating a physiological state using an estimation model. The first calculation unit calculates a first difference value based on a first estimated value of the physiological parameter in a first time interval and an actually measured value of the physiological parameter in the first time interval. The second calculation unit calculates a second difference value based on the first estimated value and a second estimated value of the physiological parameter in a second time interval previous to the first time interval. The updating unit adjusts the estimation model based on the first difference value and the second difference value.

Abstract: A living body guidance device includes: a measurement unit 1 that measures biometric information of a user; a stimulus unit 2 that is installed in contact with the user's body and presents a tactile stimulus to the user; a database unit 3 that has a relationship between the tactile stimulus presented by the stimulus unit and the biometric information according to the tactile stimulus recorded; an input unit 4 that sets target biometric information which is target biometric information that is desired of the user to realize; and a control unit 7 that, when there is a difference between current biometric information which is current biometric information of the user estimated based on the measurement result by the measurement unit and the target biometric information, controls the tactile stimulus presented by the stimulus unit so that the difference is reduced, so as to guide the user so that the current biometric information approaches the target biometric information, based on the relationship recorded in th

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.
