A method for prediction of a head impact event mechanism via an instrumented mouthguard device comprises receiving, as input, time series data representative of a head impact event, wherein the time series data is derived from the instrumented mouthguard device. The instrumented mouthguard device includes one or more accelerometers. The method further comprises generating an array of spatial coordinates representing points on a computer head model, and processing the time series data to determine a direction of impact and location of impact relative to the computer head model.

Methods and apparatuses are provided for measuring a biometric signal by an electronic device. An object having an animation effect for inhalation and exhalation is displayed. The animation effect includes the object being expanded to guide the inhalation of a user and the object being contracted to guide exhalation of the user. A sensor unit obtains at least one biometric signal related to a heart rate of the user while the object is displayed. A motion of the electronic device is detected having a strength that is greater than or equal to a threshold strength. Based on the motion ceasing before exceeding a predetermined time, display of the object and obtaining of the at least one biometric signal is continued. Based on the motion lasting longer than or equal to the predetermined time, the obtaining of the at least one biometric signal and the displaying of the object is terminated.

A game device includes a storage unit and a control unit configured to execute a game program. The control unit acquires biological information indicating physical feature of a user operating the game device, computes a biological parameter of the user based on the biological information, and stores the biological parameter in the storage unit. The control unit then computes, in accordance with the biological parameter stored in the storage unit, a property parameter that determines a property of a character generated by the game program.

Augmented reality systems and methods for user health analysis. Methods for user health analysis may include collecting data for an initial prediction model and continuing to collect additional data based on one or more data criteria. The methods may further include updating the initial prediction model based on the additional data to produce a revised prediction model or causing an intervention to occur based on the additional data. The data may be collected by a display system including one or more sensors configured to collect user-specific data and a display device configured to present virtual content to a user. The display device may be configured to output light with variable wavefront divergence.

A system for monitoring muscle load, is configured to perform operations including: obtaining, from at least one sensor, measurement data on an exerciser; determining, based on the measurement data, a number of repetitions of a macroscopic movement performed during a physical exercise; determining, based on a conversion entry corresponding to a type of the physical exercise, muscle load coefficient of one or more muscles loaded in the physical exercise; utilizing the muscle load coefficient of the one or more muscles and the number of repetitions in determining muscle load data indicating muscle specific muscle load caused by the physical exercise performed by the exerciser; and outputting the muscle load data.

A system, method and apparatus for capturing data from a plurality of users for providing online gameplay based on captured user sensor data. User sensor data is captured from a plurality of sensor capture devices relative to an associated user so as to be transmitted to a gameplay server. The gameplay server executes instructions to generate a user interface on a user's client computing device for providing gameplay on each user client portable computing device utilizing, and pertinent to, the captured sensor data.

A method for controlling a limb of a virtual avatar by the myoelectric activities of a limb of an individual. The method includes a first step of calibrating and second step of moving the limb of the virtual avatar. Also, a system suitable for implementing the method for controlling a limb of a virtual avatar by the myoelectric activities of a limb of an individual.

A system for monitoring exercise activity in a gym environment includes an image-based monitoring arrangement, a storage device, and a replay device. The monitoring arrangement generates a time series of 3D representations of an individual, with each 3D representation defining a pose of the individual and comprising 3D positions of a plurality of predefined feature points of the individual. The storage device receives and stores an exercise sequence, which comprises at least part of the time series of 3D representations and corresponds to an exercise performed by the individual. The replay device retrieves the exercise sequence from the storage device, renders an animation of the individual when performing the exercise based on the exercise sequence, and provides the animation for display. The system enables a user to review the exercise at any desirable viewing angle and/or magnification.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

An exercise system may include an exercise mat; sensors integrated into the exercise mat, each of the sensors configured to sense when a force is applied to a respective portion of the exercise mat; and displays coupled to the exercise mat and configured to display indications corresponding to desired locations for body parts of a user in accordance with an exercise routine. On one or more of the displays, indications corresponding to desired locations of a user's body part may be displayed in accordance with a form of one of stored exercise routines; and one or more of the sensors may sense an application of force to the exercise mat. One or more of the displays may display at least one marker identifying a direction from a location of the sensed application of force to a display location of the at least one of the indications.
