Various embodiments provide systems and methods for identifying impairment using measurement devices.

Biometric feedback systems and methods for measuring user reaction to the indoor or outdoor environment are described. In some embodiments, one or more user(s) wears a body-worn sensor and the user's heart rate variability or other indication of stress is monitored as the user travels along a pre-determined route.

A movable carrier auxiliary system includes a driver state detecting device and a warning device. The driver state detecting device includes a physiological state detecting module, a storage module, and an operation module. The physiological state detecting module is adapted to detect a physiological state of a driver. The storage module is disposed in a movable carrier and stores an allowable parameter corresponding to the at least one physiological state. The operation module is disposed in the movable carrier and is electrically connected to the physiological state detecting module and the storage module to detect whether the at least one physiological state of the driver exceeds the allowable parameter or not, and to correspondingly generate a detection signal. The warning device generate a warning message when the detection signal that the at least one physiological state of the driver exceeds the allowable parameter is received.

Systems, devices, and methods are disclosed for characterizing joint attention. A method includes dynamically obtaining video streams of participants; dynamically obtaining gaze streams; dynamically providing a cue to the participants to view the object; dynamically detecting a joint gaze based on the gaze streams focusing on the object over a time interval; and dynamically providing feedback based on detecting the joint gaze.

A virtual reality game- and biosignal sensor-based VOR assessment and rehabilitation apparatus includes: a biosignal sensing unit which senses and notifies of head movement and eye movement of a patient using an eye tracker and an inertial measurement unit (IMU) sensor attached or installed to a head-mounted display device; a VOR function assessment unit which configures and provides a game for VOR function assessment; a patient-personalization control unit which determines, on the basis of the VOR gain of the patient, the types and order of rehabilitation games, and a rehabilitation level; and a rehabilitation game providing unit which configures and provides games for at least one among smooth pursuit, saccades, VOR rehabilitation exercise, amplified VOR rehabilitation exercise, and suppressive VOR rehabilitation exercise, and determines the difficulty levels of the games on the basis of the rehabilitation level.

An imaging device that includes a housing mounted on the head of a subject, a camera that is held by the housing and captures an image of an eyeball of the subject, communication circuitry that communicates information with an external device, and controller circuitry that synchronizes together the image captured by the camera and an external signal output from the external device and received.

A distributed discernment system that includes discernment server including a processer running a diagnostic program and server interface permitting communications to and from the discernment server where the discernment system communicates with two or more human interface devices, where each human interface device includes display capable of presenting a video segment of a virtual human interviewer asking a question to an interviewee and sensors capable of detecting various responses of a human interviewee to each presented question where the discernment server includes a diagnostic that generates interview instructions to be provided to a plurality of human interface devices over the communications network, wherein the instructions provided to a given human interface device are intended to cause the human interface device to present certain questions to a human interviewee interacting with the device and wherein the discernment server is adapted to receive data from each of a plurality of the human interface devices and analyze such data to provide an assessment of the state of the human interviewee interacting with the human interface device.

The present disclosure provides a method for determining preference implemented by a processor, comprising: providing image content to a user; receiving electroencephalogram (EEG) data and gaze data including a series of gaze position data or gaze speed data which is measured while the content is provided; determining the user's region of interest with respect to the content based on the gaze data; determining a saccade onset time based on the gaze data; extracting EEG data during a time period including the saccade onset time, based on the EEG data; and determining whether the user prefers the region of interest based on the EEG data during the time period, and a device for determining preference using the same.

A system for transportation includes a vehicle interface for gathering physiological sensed data of a rider in the vehicle. The system includes an artificial intelligence-based circuit that is trained on a set of outcomes related to rider in-vehicle experience and that induces, responsive to the sensed rider physiological data, variation in one or more of the user experience parameters to achieve at least one desired outcome in the set of outcomes. The inducing variation includes control of timing and extent of the variation.

A fragrance suitable for a user can be provided. A mobile terminal includes: an acquisition unit that acquires a psychosomatic state from a physiological index of a user; an input unit that inputs future information of the user; a determination unit that determines a recipe including one or more types and a mixing ratio of one or more perfumes based on the psychosomatic state and the future information; and a communication unit that transmits the recipe to a fragrance generation device.
