A method includes determining a customized action routine for a person to carry out in a virtual world, where the person is wearing a virtual reality (VR) headset. Objects associated with events from the routine are presented to the person in a virtual world via the VR headset; and aspects of the person's virtual interaction with the object in the virtual world are rendered on the VR headset. The person's virtual interactions with virtual objects is analyzed and used to determine, in real time, one or more next events for said routine.

A swing measurement system measures an evaluation index of a swing of a golf club using an inertial sensor. A computer is provided with: a movement trajectory calculation unit for calculating a movement trajectory of the golf club during the swing using a detection value of the inertial sensor; a shaft plane calculation unit for calculating a shaft plane of the swing based on the movement trajectory in a freely selectable section of the swing; and an angle calculation unit for calculating, as the evaluation index, a shaft plane angle formed between the face surface of the golf club and the shaft plane.

An automatic ball launcher includes a ball feed control system that includes a meter wheel with radially-spaced ribs or grooves to selectively block and pass balls to the flywheels of the launcher. The meter wheel rotates to selectively block and release a single ball to pass at a time. The controller of the launcher can be programmed to stop the meter wheel when a ball has been metered by monitoring the current at peak of the motor driving the meter wheel. A meter-event can be determined to have occurred when the current of the drive motor drops to a trough by a pre-set magnitude following a rise to a peak value. A remote control can be provided for the user to operate the launching machine and adjust a plurality of parameters.

An exercise apparatus for strengthening muscles. The exercise apparatus includes a body having a holding portion that extends between a first distal region and second distal region thereof. The holding portion forms a continuous surface that is curved such that a diameter of the holding portion is narrowest at a proximal point of the holding portion and widest at a first radial edge and an opposing second radial edge. The first and second distal regions are each dome shaped and extend from the first radial edge and the second radial edge, respectively. The holding portion can be received between the inner thighs of a user to add resistance when performing various exercises, such as leg lifts, planks, pull-ups, dips, and the like. In some embodiments, the body includes a weight receiving channel extending therethrough, wherein an elongated weight is positioned within the weight receiving channel.

An exercise device comprising a bendable pole with spring-like properties. The bendable pole has grips at opposing ends and in a midsection. The exercise device is configured to be used for a variety of exercise methods. The exercise device provides personal fitness tracking in conjunction with a mobile software application.

An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's goggles.

This disclosure relates to a relatively compact smart ball launching system and associated methods for using the same. In various embodiments, the disclosed ball launching system may comprise a collapsible ball hopper that can store a larger number of balls while maintaining a relatively compact size. In certain embodiments, brushless motors may be used to improve power efficiency while allowing for accurate launch speeds and/or spins. In some embodiments, a pre-launch chamber may be included in a ball dispensing mechanism that may facilitate on-demand shots and/or power savings by shutting the ball launching system down when the ball hopper is empty. In further embodiments, the ball launching system may be controlled, at least in part, via a mobile device. In some implementations, the ball launching system may include and/or otherwise interface with a camera system to facilitate improved calibration and/or record user actions.

Proposed is a swing analysis device which includes a measurement unit which is coupled to a golf club of a user, and is configured to continuously measure motion data during swing motions of the golf club, an analysis unit configured to analyze the motion data continuously measured by the measurement unit to generate a swing analysis value, and a communication unit configured to transmit the swing analysis value generated by the analysis unit to a user terminal. According to the swing analysis device, as a swing analysis value generated based on motion data of the golf club is transmitted to a user terminal, the swing analysis value can be directly output by an application program installed in the user terminal without analyzing the motion data thus to greatly improve the reaction speed of the application program.
