Provided is a screen badminton practice device enabling badminton, even while alone, to be played like a real game or practiced, and enabling shuttlecocks to be automatically collected and loaded, the screen badminton practice device comprising: a screen provided at one side of a practice location; a beam projector for projecting an image on the screen; a shuttlecock shooting part, which is provided at the rear of the screen, has a storage container, provided at the upper part thereof, for storing a plurality of shuttlecocks, and withdraws and shoots the shuttlecocks stored in the storage container; and a shuttlecock collection part collecting the shuttlecocks, which fall on the lower part of the practice location, so as to fill the storage container with the same.

Provided is a sensor device including a sensor configured to output a vibration datum by detecting a change in a state of a vibration in a first object when a second object touches the first object, a holding section configured to hold, at a portion of the first object which is different from a portion where the second object touches, the sensor in a state where the vibration in the first object is transmitted, and a communication section configured to transmit the single vibration datum detected by the sensor to an analyzing device which identifies a touch position where the second object touches the first object by analyzing the vibration datum.

A sporting apparatus includes a monitoring device. The monitoring device may add no weight to the sporting apparatus relative to a comparable sporting apparatus without the monitoring device. The monitoring device may have a center of gravity substantially aligning with the center of gravity of the sporting apparatus, resulting in a sporting apparatus with a monitor having substantially the same center of gravity as a comparable sporting apparatus without a monitor. The sporting apparatus monitor may be configured to trim unreliable post impact swing data and replace it with extrapolated pre-impact swing data and/or more reliable post impact swing data.

A virtual target system, for training multiple sports, and in an example, tennis, can include a projector system that can display a virtual target on a surface, like a tennis court. A sensor system can detect activity near the virtual target, for example, the movement or impact of a tennis ball. A processor can be linked to the projector system and the sensor system to collect activity data based on the virtual target and the activity. In one example, the display of the virtual target may or may not change in reaction to the collected activity data.

A sports training/exercise apparatus attached to a swinging sports apparatus, typically a racquet and most specifically a tennis racquet. The apparatus includes a drag chute with a rigid member disposed therearound and a clamp secured to each side of the drag chute. A transverse support rod is positioned between the clamps and includes an aperture therein, The apparatus further includes brackets at the top and bottom of the racquet head. A longitudinal support rod is positioned between the brackets and extends through the aperture in the transverse support rod. Thus, the transverse support rod, the side clamps, and the drag chute are slidable along the longitudinal support rod to adjust resistance. A locking mechanism can be used to lock the transverse support rod in a position along the longitudinal support rod.

A shuttlecock loading mechanism with a grabbing mechanism and a pair of ejecting wheels defining a wheel plane. The grabbing mechanism receives a shuttlecock entering the loading mechanism in a vertical position and ejects the shuttlecock from the loading mechanism in an orientation parallel to the wheel plane wherein the pitch of the wheel plane about a wheel horizontal axis is selectively indexed about the wheel's horizontal axis.

A method, computer system, and computer program product for sport training on an augmented reality device or a virtual reality device is provided. The embodiment may include capturing a plurality of user movement data using one or more sensors. The embodiment may also include measuring a user body and eye gaze position based on the plurality of captured user movement data. The embodiment may further include calculating a body position difference by comparing the measured user body and eye gaze position with an expert-specified body position sequence. The embodiment may also include determining a body position quality threshold is not satisfied based on the calculated body position difference. The embodiment may further include generating an instruction based on the compared calculated body position difference.

A method of holding a sport equipment can comprise optionally placing a first and/or second hand in a first and/or second hand covering device. A user may position the first hand through a loop of a strap device. The user may place the first hand around a sport equipment. The user may place the second hand around the sport equipment and a grip portion of the strap device at the same time. The user may apply or attempt to apply the sport equipment to an incoming object by swinging the sport equipment in a loop trajectory such that the first hand and the second hand move together through the completion of the trajectory.

A grip adjustment system comprising: a sleeve positionable, in use, on an object configured to be gripped by a user. The system also comprises a distributed array of actuators, each actuator being arranged to actuate a respective portion of the sleeve between a first position and a second position in response to an actuation signal; and a processor. The processor is operable to: receive a pressure distribution and an event quality indicator corresponding to an event of interest; determine an optimal grip based on the pressure distribution and the event quality indicator; select an actuator, of the distributed array of actuators, to be actuated based on the optimal grip; transmit the actuation signal to the actuator such that the shape of the sleeve is changed and the grip of the user is adjusted.

A shuttlecock loading mechanism with a grabbing mechanism and a pair of ejecting wheels defining a wheel plane. The grabbing mechanism receives a shuttlecock entering the loading mechanism in a vertical position and ejects the shuttlecock from the loading mechanism in an orientation parallel to the wheel plane wherein the pitch of the wheel plane about a wheel horizontal axis is selectively indexed about the wheel's horizontal axis.
