Apparatuses, methods, systems, and program products are disclosed for adjusting display settings of a head-mounted display. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to receive sensor data from one or more sensors operably connected to a head mounted display (HMD) unit while a user wears the HMD unit. The code is executable by the processor to determine a visual acuity of the user based on the sensor data. The code is executable by the processor to adjust one or more display settings of the HMD unit based on the determined visual acuity for the user. The one or more display settings may be adjusted to correct for impairments in the user's visual acuity.

Provided are a method, a device, a system, and a program for evaluating similarity of brain activity with respect to an object to be evaluated, using data obtained by a simple measurement of brain waves. Brain wave data related to cognitive processing with respect to a plurality of sensory stimuli are dimensionally compressed, and a distribution of the object to be evaluated is displayed on a two-dimensional plane or three-dimensionally. In this way, similarity of brain information with respect to the plurality of sensory stimuli is evaluated, and the similarity is visualized. The brain wave data related to the cognitive processing include brain wave data upon selection of a stimulus as a target, and brain wave data caused by a non-target stimulus event.

Provided are systems and methods for medical diagnosis. The systems and methods may identify a coherence between paired sensor data respectively measured from a first sensor attached to a head of a subject and a second sensor attached to a body part of the subject. The systems and methods may determine an amount of volition in the subject's body based on the coherence. The systems and methods may determine a diagnosis or a treatment plan for a subject based on the amount of volition. The system and methods may be used to track interaction between individuals in a clinical setting or in a social group.

Example devices are disclosed herein that include a first elongated band coupled to a first housing to be located on a first side of a head of a subject and a second housing to be located near a second side of the head of the subject, the first elongated band comprising a first set of electrodes. The example device also includes a second elongated band coupled to the first housing and to the second housing, the second elongated band comprising a second set of electrodes. In addition, the device includes a third elongated band coupled to the first housing and to the second housing, the third elongated band comprising a third set of electrodes.

The present method and system provides for the clinical application of neurostimulation and/or neuromodulation to a patient. The method and system includes receipt and acquisition of patient data, processing of that data relative to one or more known data sets, and determination of a good-fit trigger specific treatment protocol. The method and system provides for application of the protocol to the patient, including delivery of neuromodulation and biofeedback. Based thereon, the method and system re-iterates the goodness of fit determination for further treatment to the patient.

A system for assessing brain health of a user includes an electronics module including an active brainwave sensor that collects channels of electroencephalography (EEG) brainwave data, a plurality of biological sensors, and a stimulation device. The biological sensors include a microphone that captures verbal responses of the subject during a battery of tasks, an image sensor that records eye positions, eye saccade and other biometric identification information, an accelerometer, a gyrometer, a thermometer, a pulse oximetry sensor, a dermal skin conductance sensor, and key strokes, mouse clicks or touch events to measure cognitive data of the user. The stimulation device applies a battery of tasks including a visual or photic stimulant, an auditory stimulant, a gastronomic stimulant, an olfactory stimulant, a touch stimulant, and a cognitive challenge stimulant to the user. The plurality of biological sensors simultaneously measure the body's response to stimulants for recordation by the electronics module.
