An information processing apparatus includes a selection unit. The selection unit selects whether to calibrate biological information of a user in accordance with designation by the user. When the selection unit selects no calibration in accordance with designation by the user, the biological information is associated with a specific state of the user under a predetermined condition.

A technology for a wearable medical device for monitoring medical parameters. Medical measurement data can be received at the wearable medical device from a medical measurement sensor attached to the wearable medical device or a medical measurement sensor in communication with the wearable medical device. A calibration coefficient can be determined for calibrating the wearable medical device based on the medical measurement data. The wearable medical device can be calibrated based on the calibration coefficient.

A method comprising: acquiring via a network biogas information representing a concentration of furfural of the user acquired by a sensor that detects the furfural discharged from a skin surface of the user; obtaining the reference information representing a lower limit of a normal range of the concentration of furfural per unit period of time, using a memory storing the reference information; and outputting information related to stress of the user an information terminal of the user, after it is determined that a frequency that concentration of the furfural of the user per the unit period of time is less than the lower limit of the normal range tends to increase, based on the biogas information acquired in a pregnancy period of the user.

A method includes: acquiring, via a network, biogas information at multiple timings and time information corresponding to time at each of the multiple timings, wherein the biogas represents a concentration of 2-ethylhexanoic acid of a user acquired by a sensor that detects the 2-ethylhexanoic acid discharged from a skin surface of the user; obtaining reference information representing a lower limit of a normal range of 2-ethylhexanoic acid per unit period of time, using a memory storing the reference information representing the lower limit of the normal range; determining a stress time period during which a concentration of the 2-ethylhexanoic acid of the user is less than the lower limit of the normal range, based on the acquired biogas information; and outputting time period information indicating the determined stress time period to an information terminal of the user.

In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of 2-ethyl-1-hexanol of the user and is obtained by a sensor that detects 2-ethyl-1-hexanol released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of 2-ethyl-1-hexanol per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of 2-ethyl-1-hexanol of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

An apparatus (100) for determining a stress and/or pain level of a subject comprises a processor (102). The processor (102) is configured to acquire, from a photoplethysmography sensor (104), a photoplethysmography signal obtained from a central part of the body of the subject. The processor (102) is also configured to identify a characteristic of the acquired photoplethysmography signal. The characteristic is normalized for blood pressure. The processor (102) is further configured to determine the stress and/or pain level of the subject from the acquired photoplethysmography signal based on the normalized characteristic.

An information processing apparatus includes a processor. The processor is configured to determine a level of load on a user in accordance with communication-related information of the user and biologically-related information of the user, identify a factor that applies the load on the user in accordance with the level, and output the identified factor.

An information processing apparatus includes an acquisition unit, an association unit, and a guide unit. The acquisition unit acquires biological information of a user. The association unit associates the acquired biological information with a specific state of the user. The guide unit guides the user to the specific state. A reference to be used for association with the specific state by the association unit is calibrated by using the biological information, the biological information being acquired from the user who is guided to the specific state by the guide unit.

Embodiments are disclosed herein for providing an immersive reality experience to a patient during a medical procedure. In one example, a method includes determining a location of a stressful object in a medical environment that includes a patient undergoing a medical procedure. The method further includes, upon determining that the stressful object is in a field of view (FOV) of the patient, adjusting display content based on the location of the stressful object within the FOV and outputting the display content for display on an immersive device.

The present invention conducts an analysis on a user who has actually seen a commercial product or the like. An assessment system is provided with a biological information measurement device, a response state assessment unit, and a notification unit. The biological information measurement device measures biological information of a customer who has been presented with a provided commercial product and/or a provided service. The response state assessment unit identifies a response state of the customer who has been provided with the presentation, by making an assessment based on the biological information measured by the biological information measurement device. The notification unit gives notice based on the customer's response state identified by the response state assessment unit.
