A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises an elongated fabric body sized to encircle a limb of a user, one or more shape-memory wires carried by the fabric body and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, and a micro-processor based controller for selectively actuating the one or more shape-changing elements to reduce the effective diameter of the device encircling the limb, to thereby apply pressure to the limb.

A golf training aid is described that stabilizes a wrist and an elbow of a golfer during a golf swing. The golf training aid includes a flexible sleeve and an elongated rigid insert. The flexible sleeve is configured to receive the wrist and the elbow of the golfer. The elongated rigid insert is secured to the flexible sleeve. The flexible sleeve keeps the rigid insert in contact with the wrist and the elbow of the golfer so as to prevent pivoting of the wrist and pivoting of the elbow.

An information processing device includes a first member that includes a substantially plate-shaped casing and a predetermined detection unit, a second member that includes a substantially plate-shaped casing and that holds a battery inside the second member, and a connection unit that includes an elastic body and connects a part of an outer circumferential end surface of the first member to a part of an outer circumferential end surface of the second member such that a surface direction of one surface of the first member substantially matches a surface direction of one surface of the second member. The information processing device is worn on a predetermined body part such that the one surface of the first member and the one surface of the second member are located on a side of the body part.

A twist-inhibiting collar for sports is disclosed. The twist-inhibiting collar includes a first surface configured to engage with an ulnar edge of a first hand of a player, and a second surface configured to engage with a radial edge of a second hand of the player, the second surface opposite the first surface. The collar also includes an aperture passing through the first surface and the second surface and defined by an interface surface that is coupled to a sport implement held by the player. The twist-inhibiting collar includes an elastomeric material. The sport implement may be a bat having a handle, and the aperture may be sized to fit the handle. The sport implement may be a golf club having a grip, and the aperture may be sized to fit the grip.

A swing training device is provided. The swing training device embodies a mask adapted to place an aperture at a predefined focal length in front of the eyes of the athlete. The mask is adapted to attach to various headgear. The mask provides guides for selectively retaining diaphragms with their own diaphragmatic apertures over the aperture.

A golfing appartaus for assisting a golfer in putting includes a guide member adapted to encourage only certain motions during the golf swing to improve the engagement of ball with club and subsequently improve ball control, trajectory and speed. Further the golfing apparatus includes a movable member configured to slide along a path defined by the guide member and coupled with the putter handle. The guide member is afixed to the waist of a golfer. The guide member is curved to follow a natural rotation of arms and shoulders of the golfer and can be adjusted for proper angle that best fits a golfer's stance and has a second planar back stop surface to further align and control the movement of the putter club head, thereby assisting the golfer in putting.

Electronic tracking systems are disclosed for assisting users with locating objects in a sporting environment. One such system includes a ball tracking component that tracks a game ball while moving in the sporting environment, and a heads up display that is worn by the user. This heads up display has an electronic display screen with a transparent display area that dynamically displays images within the user's field of view. A processor, which communicates with the ball tracking component and heads up display, is programmed to detect movement of the game ball, and responsively determine launch characteristics and/or flight characteristics of the moving game ball. The heads up display displays the launch/flight characteristics contemporaneous with an object indication adjacent to or superimposed over the moving game ball as the game ball is visible through the transparent display area of the display screen within the user's field of view.

A skill determination device determines each second frame corresponding to phase types from second frames having position information of a feature point, which corresponds to a predetermined part or a joint of a body of a second user, based on phase definition information in which a plurality of first frames having position information of a feature point corresponding to a predetermined part or a joint of a body of a first user and the phase types corresponding to the plurality of first frames, respectively, are associated with each other and determines a feature amount of a motion, an attitude, or the joint of the second user derived from the feature point included in the second frame determined for each of the phase types.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises an elongated fabric body sized to encircle a limb of a user, one or more shape-memory wires carried by the fabric body and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, and a micro-processor based controller for selectively actuating the one or more shape-changing elements to reduce the effective diameter of the device encircling the limb, to thereby apply pressure to the limb.
