A balance training system including a riding plate; a load distribution sensor; a load sensor; a mobile body on which the riding plate, the load distribution sensor, and the load sensor are disposed; and a control unit configured to calculate a reference position based on positions of feet of a trainee detected by the load distribution sensor, then calculate a center of gravity position of the trainee based on the load detected by the load sensor, and control a movement of the mobile body based on a change of the center of gravity position with respect to the reference position. The control unit is configured to update the reference position based on the changed positions of the feet of the trainee when the change of the position of at least one of the feet of the trainee is detected by the load distribution sensor.

An apparatus for determining a non-apparent attribute of an object having a sensor portion with which the object makes contact and to which the object applies pressure. The apparatus has a computer in communication with the sensor portion that receives signals from the sensor portion corresponding to the contact and pressure applied to the sensor portion, and determines from the signals the non-apparent attribute. The apparatus has an output in communication with the computer that identifies the non-apparent attribute determined by the computer. A method for determining a non-apparent attribute of an object.

A medical rehabilitation device for clinically rehabilitating individuals suffering from medical conditions affecting the vestibular ocular system, and other neurocognitive functions. The rehabilitation device includes a support base having an elongate slot, and a plurality of arms adjustably attached to the support base via the elongated slot, where each arm includes a magnetic strip for selectively positioning visual targets thereon to solicit patient recognition of colors and positions of the visual targets during both vestibular ocular reflex, and other neurocognitive exercises. Each arm and the support base includes measurement markings extending along the top longitudinal surface of each arm adjacent the magnetic strips and along the elongate slot, respectively, to provide measured and objective charted indicators for vestibular ocular reflex and other neurocognitive functions over time. The arms are adjustable in horizontal, vertical, and diagonal positions to selectively adjust the difficulty of the exercises in a plane of vision.

Embodiments herein relate to ear-worn devices and, more specifically, ear-worn devices that can measure reaction and/or reflex speeds. An ear-worn device herein can include a control circuit, a clock circuit in electrical communication with the control circuit, a motion sensor in electrical communication with the control circuit, an electroacoustic transducer for generating sound in electrical communication with the control circuit, and a power supply circuit in electrical communication with the control circuit. The ear-worn device can be configured to initiate generation of a stimulus sufficient to generate a response from the ear-worn device wearer. The ear-worn device can be configured to monitor for a qualified response to the stimulus and measure an amount of time between the stimulus and the qualified response. Other embodiments are also included herein.

A device for motion sickness reduction. The device operates by providing haptic feedback using transducers that convert electrical signals to a tactile sensation such as pressure, vibration, electrical stimulation, temperature, or airflow. The transducers are located at different locations on the body of a user, and actively change their operation to indicate a direction of motion or rotation to the user through haptic (tactile) feedback. This tactile feedback can be used to reduce motion sickness. In an embodiment, the feedback is improved by deducting motion associated with the user's visual frame of reference from motion associated with the user's vestibular frame of reference.

An apparatus for determining balance compensation includes a platform, sensors and a processor. The platform is configured for a person to stand on the platform. The sensors are coupled to the platform and measure at least one of a weight and a pressure. The processor determines a balance of the person based on the measurements of the sensors.

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

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.

According to one aspect, a system for augmented reality visualization of benign paroxysmal position vertigo (BPPV) disorder. The system includes a camera configured to capture an image sequence, a processing unit configured to generate at least one virtual model of an inner ear, wherein the at least one virtual model of the inner ear comprises an accurate anatomical representation of a real human inner ear; and a display configured to display the at least one virtual model of the inner ear over the image sequence.

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.
