An activity tracking system includes a sensor device and a display device. The sensor device is configured to be carried by the user and includes at least one sensor configured to obtain the activity data for the user. The display device includes a display screen. The display device is configured to receive the activity data obtained by the sensor device and display the activity data about a circular axis on the display screen. The activity data includes sleep data on one side of the circular axis and awake data on an opposite side of the circular axis. The sleep data includes a start time and an end time for a daily retired sleep period, the end time occurring in a selected day and the start time occurring in a previous day.

Optimizing and/or personalizing activities to a user through artificial intelligence and/or virtual reality.

An information processing apparatus includes a processor configured to associate information indicating a recognition result of a voice of a user uttered at a time at which the user manually operates a device, biological information other than the voice of the user, and manual operation information indicating a manual operation for the device with each other, and operate the device based on the biological information in a subsequent operation.

A sleep-monitoring cap includes interconnected electrodes embedded within a body of the sleep-monitoring cap. The interconnected electrodes are located at positions across a central transverse region, below and along a side of each eye, and on a rear mid-region of a person's head when wearing the sleep-monitoring cap. The sleep-monitoring cap includes a vibratory device embedded within the sleep-monitoring cap, wherein the vibratory device is connected to the interconnected electrodes. The sleep-monitoring cap includes processing circuitry embedded within the sleep-monitoring cap. The processing circuitry is configured to monitor, convert, process, and store brain wave activity retrieved by the interconnected electrodes from the person wearing the sleep-monitoring cap; determine whether the monitored brain wave activity includes low amplitude mixed-frequency waves and if so, activate the vibratory device; determine whether the monitored brain wave activity includes theta waves followed by vertex sharp waves and if so, activate the vibratory device.

A method includes receiving physiological data associated with a user during a sleep session. The method also includes determining a sleep-wake signal for the user during the sleep session based at least in part on the received physiological data. The method also includes determining one or more sleep-related parameters for the user during the sleep session based at least in part on the sleep-wake signal. The method also includes determining that the user experienced insomnia during the sleep session based at least in part on at least one of the one or more sleep-related parameters. The method also includes identifying a type for the insomnia experienced by the user based at least in part on the one or more sleep-related parameters.

A measurement device includes a light emitting element configured to irradiate a blood vessel of a subject with light, a light receiving element configured to output an optical signal from the subject as an electric signal, and a controller electrically connected to the light receiving element. The controller estimates a heart rate of the subject on the basis of a part of a plurality of frequency components included in output of the light receiving element.

A system for displaying information indicative of driving conditions, to a driver, using a smart ring are disclosed. An exemplary system includes a smart ring with a ring band having a plurality of surfaces including an inner surface, an outer surface, a first side surface, and a second side surface. The system further includes a processor, configured to obtain data from a communication module within the ring band, or from one or more sensors disposed within the ring band. The obtained data are representative of information indicative of one or more driving conditions to be displayed to the driver. The smart ring also includes a light emitting diode (LED) display disposed on at least one of the plurality of surfaces, and configured to present information indicative of the one or more driving conditions.

Devices and systems provide methods of controlling breathable gas generation such as for a respiratory treatment and/or for controlling ionization of the gas. In an example, a controller of a respiratory treatment apparatus controls generation of a supply of ionized air. The apparatus may include a flow generator to generate a flow of pressurized breathable gas. The flow generator may be adapted for connection with a respiratory interface. The apparatus may also include an ionizer to ionize the flow of gas. The controller may be coupled with the ionizer and the flow generator and be configured to control the ionizer to programmatically change levels of ionization of the gas. Such ionized gas treatments may be suitable for helping users to sleep or improving respiratory oxygen absorption, and may be for patients with, for example, sleep disordered breathing or chronic obstructive pulmonary disease.

Approaches to determining a sleep fitness score for a user are provided, such as may be based upon monitored breathing disturbances of a user. The system receives user state data generated over a time period by a combination of sensors provided via a wearable tracker associated with the user. A system can use this information to calculate a sleep fitness score, breathing disturbance score, or other such value. The system can classify every minute within the time period as either normal or atypical, for example, and may provide such information for presentation to the user.

Methods and systems for improving headache pain by using feedback mechanisms are provided.
