A method can include projecting one or more objects along one or more pre-determined trajectories toward a target zone, with each having a diameter less than a diameter of a regulation table tennis ball, the trainee attempting to prevent the one or more objects from entering the target zone and scoring the ability of the trainee. A method can include displaying a first video to a trainee that explains setup for a delivery device, setting up the delivery device based on the first video, projecting an object along a pre-determined trajectory toward a target zone proximate the trainee, wherein the object has a diameter that is less than a diameter of a regulation table tennis ball, and scoring an ability of the trainee to interact with the object at the target zone.

A variable-resistance exercise machine with network communication for smart device control and interactive software applications, comprising a network interface that receives input from a user device and provides output to a user device; a plurality of moving surfaces that each provide an independent degree of resistance to movement based on received input, a sensor that detects movement and provides output to a user device based on the movement.

A green simulation apparatus may comprise a covering forming a configurable upper surface with a changeable contour and being flexible such that the covering is movable between a base condition in which the upper surface has a substantially planar configuration and a contoured condition in which the upper surface has a contoured configuration. The apparatus may also comprise a covering support assembly configured to support the covering in the base condition and the contoured condition.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

A system and method for analyzing the swing motion of sporting equipment, for example, a golf club, including at least one or more inertial acceleration sensors, one or more gyrometric sensors, a data acquiring unit, a core micro-controller, and a Bluetooth radio. The motion detecting unit detects at least one motion of the swing. Particularly, the sensors and data acquiring unit calculates swing information using the acquired detection data to match a user’s swing motion to optimized equipment. Particularly, the data acquiring unit acquires detection data from the sensor(s) and forwards such data to a computing device or server having stored information that matches the swing motion to an optimized swing device.

Embodiments provided herein measure metrics of an athletic action and an object associated therewith, and more particularly, to measuring the metrics and characteristics of a baseball during the wind-up, release, flight, and catch of a pitch sequence. Methods may include: receiving, from at least one motion sensor associated with an object, acceleration data and angular velocity data of the object in response to an athletic action performed on the object; processing the acceleration data to establish vector rotation data between a frame of reference of the object and an Earth frame of reference; applying the vector rotation data to the acceleration data to obtain acceleration of the object in the Earth frame of reference; applying the vector rotation data to the angular velocity data to obtain angular velocity of the object in the Earth frame of reference.

A golf coaching system and a method thereof are disclosed. The golf coaching system may include: a swing measurement device that measures at least one of a swing trajectory and a posture change during a swing; a striking prediction device that predicts striking by measuring at least one of a ball speed, a swing speed, and a launch angle; and a data analysis server that generates coaching information based on data measured by the swing measurement device and the striking prediction device.

To more effectively improve mobility impairment of a user by supporting rehabilitation, this invention provides a rehabilitation support apparatus for supporting rehabilitation of a user with mobility impairment, including a requester that requests a target action in a three-dimensional virtual space, and a feedback unit that performs feedback that stimulates at least two of five senses to the user who has performed the target action almost at the same time as a timing of performing the target action.

A virtual reality (VR) system comprising a head-mounted display (HMD) and handheld controller set is enhanced to provide a more realistic end user VR experience, e.g., for boxing or other interactive training. In this approach, and in lieu of simply establishing a boundary area for the VR experience, the user also maps a position of a real-world object into a reference frame of the VR environment. This mapping is facilitated using the handheld controller itself, e.g., as positioned in a backwards-facing manner on the user's forearm. The real-world object is then simulated in the 3D VR environment as rendered by the VR HMD, and the user interacts with the real-world object (or its simulation) to provide a more enjoyable and useful interactive experience.

Among other things, a processor executes instructions to (a) during a current instance of an exercise activity having a predefined scope and being performed by a subject competitor on a machine, compute a first performance metric for the subject competitor using performance data from the subject competitor's performance of a lesser scope than the predefined scope of the current instance of the exercise activity, the first performance metric being normalized to reflect a hypothetical performance over the predefined scope, (b) receive performance data representing an historical performance during a previous instance of the exercise activity by at least one other competitor on a machine, and (c) present to the subject competitor comparative data based on the first performance metric and on a second performance metric for the historical performance by at least one other competitor that is based on the received performance data and that reflects performance of the at least one other competitor of a scope of the previous instance that is substantially the same as the predefined scope.
