A wearable sensor device includes a temperature and humidity sensor that measures ambient environmental information around a living body, a snap button connected to a bioelectrode, a biological information measurement unit that measures biological information, an inertial sensor that measures inertial information, a calculation unit that calculates a biological feature amount based on the biological information and calculates an inertial feature amount based on the inertial information, and a wireless communication unit that transmits the biological information, the inertial information, the biological feature amount, the inertial feature amount, and the environmental information to the outside.

Wearable sensor device

A wearable environmental sensor device includes a temperature/humidity sensor disposed on a wall surface of a housing that is exposed to an environment and configured to measure ambient environmental information around a living body, and a protective structure formed around the temperature/humidity sensor. The temperature/humidity sensor is disposed, directly or via a support structure, on or over the wall surface of the housing, wherein the wall surface faces substantially downward from the living body when the wearable environmental sensor device is attached to the living body and the living body is in a standing posture. The protective structure has respective ventilation holes provided in two or more pairs of opposed surfaces thereof each facing in a direction other than a vertical direction of the living body when the wearable environmental sensor device is attached to the living body and the living body is in the standing posture.

Wearable environmental sensor device and monitoring system

A tactile device includes a wearing portion to be worn on a subject, a tactile stimulus generation portion that provides a tactile stimulus to a body surface of the subject, and a positioning portion that makes a place where the wearing portion is worn constant. The tactile stimulus generation portion is fixed to the wearing portion. The wearing portion is worn on an arm of the subject. A tactile stimulus is provided to a body surface of the arm of the tactile stimulus generation portion. The positioning portion is, for example, a glove integrally formed with the wearing portion.

Tactile device

A wearable sensor device includes a temperature and humidity sensor that measures ambient environmental information around a living body. The temperature and humidity sensor is provided on an outer wall surface of a housing or provided to be separated from the outer wall surface. The outer wall surface of the housing faces a left or right side or diagonally downward when the wearable sensor device is attached to the living body and the living body is in a standing posture.

Wearable sensor device and monitoring system

An embodiment tactile presentation method includes: generating a first stimulus signal in a first frequency band; generating a second stimulus signal in a second frequency band, the second frequency band different from the first frequency band; applying the first stimulus signal from a first application member to a skin surface of a living body; and applying the second stimulus signal from a second application member to the skin surface.

Tactile presentation device and tactile presentation method

An electronic device includes: a housing; an actuator installed inside the housing and configured to generate vibration in response to an application of a driving voltage; a temperature sensor configured to detect an operating temperature caused by the actuator; and a control circuit configured to apply the driving voltage to the actuator to drive the actuator, thereby generating a traction illusion, where the control circuit restricts an operation of the actuator, based on the operating temperature detected by the temperature sensor.

Electronic apparatus and control method

Inside a housing of electronic equipment, a first actuator for generating vibration along a first axis is mounted. The first actuator is mounted in a direction in which the first axis is non-parallel and non-perpendicular to at least one of the six surfaces.

Electronic apparatus that generates illusion of diagonal traction

A haptic system includes a haptic device and a control device. A sensor of the haptic device detects contact of a finger of a user who grips a casing, a determination unit of the control device determines whether sensor information on a contact position of the finger detected by the sensor of the haptic device matches preset reference position information, and an instruction unit sends a notification unit a notification instruction in at least one of cases where the sensor information does not match the reference position information and where the sensor information matches the reference position information. On accepting the notification instruction, the notification unit of the haptic device notifies the user of an indication indicating that the contact position of the finger is shifted or an indication indicating that the contact position of the finger matches the reference position.

Tactile system

A sensor detects contact of a finger of a user who grips a casing. A determination unit determines whether sensor information on a contact position of the finger detected by the sensor matches preset reference position information. A notification unit notifies the user of at least one of an indication indicating that the contact position of the finger is shifted from a reference position and an indication indicating that the contact position of the finger matches the reference position when the sensor information matches the reference position information. A tactile stimulus generation unitprovides a tactile stimulus for the user gripping the casing.
