The present disclosure relates to methods, non-transitory computer readable media, and devices, for detecting virtual reality sickness causing content in virtual reality motion simulators. A visual perception measurement of a virtual reality content being displayed on a head-mounted virtual reality device of a virtual reality motion simulator is determined. A vestibular perception measurement of the virtual reality content is then determined. The visual perception measurement and the vestibular perception measurement of the virtual reality content are compared. An indication of a user experience in the virtual reality motion simulator is determined based on the comparison and the indication of the user experience is output.

A remote diagnostic system and method for collecting eye-movement data includes a mobile visual recording device which is mounted on a set of goggles. In this combination, the recording device will necessarily include both a camera and a computer. With the combined visual recording device and goggles stabilized on the head of a patient/user, a blackout vision chamber is established in front of an eye of the patient/user. An illuminator on the goggles can then be activated to illuminate the eye, and the camera in the visual recording device can record eye-movement data from the patient's eye while it is illuminated. A programmed protocol from the computer directs the patient using voice commands through a predetermined sequence of head orientations in space and collects eye-movement data that is used to generate a record of nystagmographs and gyroscopic head positions/stabilization data. The record of eye movements can then be automatically uploaded and viewed remotely by physicians via the web-based browser for diagnostic purposes.

A system for diagnosing vestibular otolith function can comprise an ultrasonic generator that is configured to direct ultrasonic waves towards vestibular organs with a patient's ear. The system can also comprise a response capture device that is configured to capture patient response to the ultrasonic waves.

A system for transdermal alcohol sensing to be worn near a skin surface of a user, including: an alcohol sensor; a microporous membrane; a housing coupled to the alcohol sensor and the membrane, defining a volume between the alcohol sensor and a first membrane side, and fluidly isolating the volume from a second membrane side opposing the first membrane side; an electronics subsystem electrically coupled to the alcohol sensor, operable to power and receive signals from the alcohol sensor; and a fastener operable to position the second membrane side proximal the skin surface.

Apparatus and methods for estimating a vestibular function of a subject include a motion platform for supporting a subject and an input device configured to receive confidence ratings from the subject. The motion platform is configured to execute one or more motions. The confidence ratings are related to the subject's perception of the one or more motions. The apparatus further includes a processer configured to fit a cumulative distribution function to the confidence ratings, determine a relationship configured to link the cumulative distribution function to an underlying noise distribution, and output parameters associated with the vestibular function based at least in part on the relationship.

Disclosed is an apparatus and method for identifying the gaze stability of a patient. The apparatus includes a head mounted device configured to a patient head, wherein the head mounted device is adapted to track the movement of the patient head. Further, the apparatus includes a display adapted to display a graphic pattern, a perception module adapted to receive perception information regarding the patient's call out of the graphic and a data processing device adapted to control and execute the function of the display, the head mounted device, the perception module based on the inputs received from the perception module.

A feedback device for measuring balance related information, and for producing a stimulation of the skin that encodes that information in a way that is useful to the wearer of the device. At least one sensor detects balance information and transmits at least one balance information signal to a signal processing subsystem. The signal processing subsystem converts the received balance information signal into at least one stimulation control signal. The signal processing subsystem then transmits the stimulation control signal to at least one stimulator, which provides stimulation to a wearer of the device reflecting the stimulation control signal received from the signal processing subsystem.

A feedback device for measuring pressure related information, and for providing that information in a way that is useful to the wearer of the device. At least one sensor detects pressure information and transmits at least one pressure information signal to a signal processing subsystem. The signal processing subsystem converts the received pressure information signal into at least one stimulation control signal. The signal processing subsystem then transmits the stimulation control signal to at least one stimulator, which provides stimulation to a wearer of the device reflecting the stimulation control signal received from the signal processing subsystem.

Systems and methods for assisting body movement of a user are disclosed according to various embodiments. In one example, a disclosed system includes: at least one sensor, a feedback device, a memory storing pre-configured values, and a processor. The at least one sensor is configured for measuring force or pressure applied by the user on a seat. The feedback device is configured for providing feedback to the user based on a force or pressure measurement from the at least one sensor. The processor is configured to: receive the force or pressure measured by the at least one sensor, calculate a percentage based on the force or pressure measurement and the pre-configured values stored in the memory, determine whether the calculated percentage falls within a predetermined range, and cause the feedback device to provide a feedback to the user when the percentage falls within the predetermined range. The feedback indicates the force or pressure applied by the user on the seat.
