A method for identifying brain injuries in a test subject includes acquiring, at a selected number of instances across a selected time interval, a set of signals indicative of force from a set of force sensors when the test subject stands on a pressure measurement unit. The method includes calculating a center-of-pressure of the test subject at the selected number of instances across the selected time interval based on the acquired set of signals from the set of force sensors. The method includes calculating a metric indicative of randomness of the center-of-pressure of the test subject across the selected time interval. The method includes determining a state of brain health of the test subject based on the metric indicative of randomness of the center-of-pressure. The method includes reporting the state of brain health of the test subject to a user interface.

A biological information processing device includes a controller programmed to obtain biological information indicating a body condition, and associate different kinds of the biological information with respective specific graphical elements. Each of the specific graphical elements is same kind of element that constitutes an appearance of a graphical figure. The controller is further programmed to set value to the specific graphical element depending on degree of the biological information for the at least one specific graphical element associated with the obtained biological information, and generate indicating data of a biological figure that is an aggregate of the specific graphical elements on the basis of the set value.

Methods, systems, and computer programs are presented for managing motion sickness of a user while the user is wearing a head-mounted device (HMD). One method includes an operation for monitoring the physical characteristics of the user while wearing the HMD that is presenting a virtual reality with multimedia content, where the physical characteristics including motions of the user. The multimedia content includes audio and video for presentation on a display of the HMD. Additionally, the method includes an operation for determining if the user is experiencing motion sickness based on the monitoring of the physical characteristics of the user while the virtual reality is being presented. When the user is experiencing motion sickness, supplemental sound is delivered to the user, where the supplemental sound is combined with sound from the multimedia content for delivery to the user, and the supplemental sound is defined to decrease the motion sickness experienced by the user.

In one embodiment, one or more suspension systems of a vehicle may be used to mitigate motion sickness by limiting motion in one or more frequency ranges. In another embodiment, an active suspension may be integrated with an autonomous vehicle architecture. In yet another embodiment, the active suspension system of a vehicle may be used to induce motion in a vehicle. The vehicle may be used as a testbed for technical investigations and/or as a platform to enhance the enjoyment of video and/or audio by vehicle occupants. In some embodiments, the active suspensions system may be used to perform gestures as a means of communication with persons inside or outside the vehicle. In some embodiments, the active suspensions system may be used to generate haptic warnings to a vehicle operator or other persons in response to certain road situations.

A method and system for monitoring a user's intoxication including receiving a set of signals, derived from a set of samples collected from the user at a set of time points; providing a sobriety task to the user proximal to a time point of the set of time points; generating a performance dataset characterizing performance of the sobriety task by the user; receiving a supplementary dataset characterizing a demographic profile of the user and/or a physiological state of the user; determining a set of values of an intoxication metric, derived from the set of signals; generating a predicted temporal profile of the intoxication metric for the user based upon the set of values, the set of time points, and the supplementary dataset; generating an analysis of the user's sobriety based upon the performance dataset and the predicted temporal profile; and providing a notification to the user based upon the analysis.

A sensor system and method for determining if an environment is provocative, measuring a human response to this environment, and controlling a vehicle or device is disclosed. The system and method comprise a human head-worn unit with an orientation sensing element, a head-attachable display comprising a first image not responsive to pitch and roll and a display element responsive to the orientation sensing element. The system and method also comprises at least one human response sensor such as a galvanic skin response sensor, a blood pressure sensor, or an electroencephalograph. The system and method further comprise an algorithm that computes a signal that is a measure of the condition of the human based on input from the orientation sensing element and the human response sensor or sensors. The system and method also comprise an electronic interface configured for transmitting the human physical condition signal.

The invention relates to a device for measuring the perception of equilibrium in individuals comprising an opaque mask having an inclination sensor and a display arranged within the mask for displaying an image, which can be rotated in order to determine the subjective visual vertical of an individual, and having a means for detecting the posture of the individual, and a monitoring unit which, during the determination of the subjective visual vertical, indicates and/or stores the position and/or movement of one or more areas of the body. During the measurement of the sense of equilibrium, the subjective visual vertical is determined and, at the same time, the posture of the individual is measured.

The present invention relates to systems and methods for helping subjects improve safety and efficiency of their movements; particularly subjects who have suffered an injury or suffer from a movement or other such disorder. More particularly, the present invention relates to such a system and method for monitoring a subject's movement to detect or predict unsafe, undesirable, or impaired movements, or symptoms of movement disorders, and also a system for providing possible treatment methods for such conditions. The present invention further relates to a method and system of providing cues or stimuli to the subject when such unsafe or undesirable movements, instabilities or symptoms are detected or predicted. Most particularly, the present invention relates to a subject-customized and adaptive movement recovery system, and method of providing therapy and training to improve functional motor recovery and safety of movement of a subject suffering from an injury or from movement disorder(s).

Particular vibratory signals are delivered to the vestibular system in order to reduce or prevent symptoms of maladies of the vestibular system.
