Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

A method, apparatus, or system for reducing gait asymmetry is disclosed. The method, apparatus, or system may include measuring one or more gait parameters of an individual; calculating a joint metric based on the measured one or more gait parameters; and signaling an adjustment of an amount of one or more perturbation techniques based on the joint metric for reducing asymmetry in a gait pattern of the individual. The one or more perturbation techniques include asymmetric rhythmic auditory cueing making a first audible cue with a first cue duration for one leg of the individual and a second audible cue with a second cue duration for another leg of the individual. Here, the first cue duration is different from the second cue duration. Other aspects, embodiments, and features are also claimed and described.

The force measurement system includes a force measurement assembly configured to receive a subject, a motion base for displacing the force measurement assembly, and one or more data processing devices operatively coupled to the force measurement assembly and an actuation system of the motion base. The motion base includes a support structure; a displaceable carriage coupled to the force measurement assembly; and an actuation system, the actuation system including one or more actuators operatively coupling the displaceable carriage to the support structure, the one or more actuators configured to displace the displaceable carriage with the force measurement assembly relative to the support structure, the displaceable carriage being suspended below a portion of the support structure.

Methods for automatically monitoring operation of a motion tracking system and actuating based on the operation, the motion tracking system comprising both a computing device, and a plurality of inertial measurement units adapted to be arranged on a body of a user. The computing device processes measurements of the units and sound captured by at least one microphone to provide flags related to the motion tracking procedure with regards to the motion input and the sound input, and actuates when motion-related flags and sound-related flags have been provided.

According to an augmented reality based interactive sports device using a LiDAR sensor proposed in the present invention, it is possible to allow enjoying sports indoors only with the user's body without requiring a user to wear a separate object or device by projecting an image for sports content on the floor and tracking a user motion of the sports content using the LiDAR sensor to control the interaction between the sports content and the user, allow using the floor surface efficiently due to wide range of motion tracking, and allow quickly and accurately tracking a motion of each user by tracking a user motion using two LiDAR sensors even when multiple users are using sports content at the same time.

An exercise therapy video game and monitor system for physical targeted activation and cognitive skills for learning fluency of an individual. More specifically, the system includes a whole-body fitness program that integrates motion, motor-sensory learning, and vision using games and motion sensing technology to track video-directed body position and movements of the individual. The system includes at least a first gaming platform, interactive exercise software to provide movement instructions to the individual, a computing system, and one or more sensors, such as motion sensors or sensors associated with a mat, to track body positions and movements of the individual. The system can then provide instant feedback to improve the body positions and movements of the individual to better replicate video directions.

The present invention provides methods and tools for improving training regimes and optimizing exercise effects. It is ideally suited for rehabilitation services, sports medicine, gym workouts, occupational therapy, physical therapy, and training setups including especially arduous endeavors or occupations, such as military personnel, fighter pilots, astronauts, law enforcement, intense athletes, etc. This invention provides enhanced biofeedback towards a complete and comprehensive understanding of the body's real-time metabolic status and capabilities. Specialists, such as cardiologists and vascular surgeons, will find the simultaneous feedback from separate quadrants of the body especially useful in predicting future events. A series of wearable wireless nanosensor appliances on the body and/or in handlebars, grips, gloves, etc., monitors biomolecules emitted from hands, ankles, fingers, head, torso, etc. The analytical system assesses real-time metabolic status of the individual. Both small and large molecules can be analyzed, e.g., to indicate the fuels being used (e.g., proteins, sugars, fats), tissue breakdown products (including, but not limited to skeletal muscle, cardiac muscle, ketones, fat cells, etc.), hormones, liver and lung metabolites, etc. Devices of the invention use highly sensitive compound selective nanosensing elements to produce real-time status and summary reports immediately available to the practicing individual, coach, manager, teammate, therapist, and/or other selected party of interest.

Described herein are various mobile entertainment systems. A system can include a housing defining an inner volume and a plurality of externally facing apertures; and a plurality of tracks that each traverse a portion of the inner volume. A track may connect an externally facing aperture to a second externally facing aperture. An externally facing aperture receives as an input or provides as an output an object. The object may travel along a track from an externally facing aperture to a second externally facing aperture. The system can further include electronics for generating one or more visual or auditory effects; one or more sensors coupled to the housing, an object, or a prop; and/or one or more props, each connected to a drive motor. A microcontroller of the system activates the electronics, sensors, and/or drive motors based on a library of motion profiles or effect profiles and/or received sensor data.
