A motion recognition method includes acquiring skeleton information, in chronological order, that includes positions of respective joints of a subject performing a series of motions that includes a plurality of basic motions, using a processor. The motion recognition method includes first determining which one of a first motion recognition method using a first feature amount that is determined as a result of the basic motion, and a second motion recognition method using a second feature amount that changes in a process of the basic motion is to be adopted, depending on a type of the basic motions, using the processor. The motion recognition method includes second determining a type of the basic motion by using the skeleton information by either determined one of the first motion recognition method and the second motion recognition method, using the processor, and outputting the determined type of the basic motion, using the processor.

The invention relates to social activities typically based on physical manipulation of objects to achieve an objective common to the participants or to allow participants to engage in distinct activities on a shared field of play, part of which is physical and part of which is virtual and rendered on one or more displays. The invention provides a system and method to enable multiple participants (users) to engage in the activity sequentially or simultaneously, based on the context and objectives of the game. The activity includes one or many shared physical environments modeled on a computing system and displayed, in high fidelity, by one or more projectors or screens.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a basketball backboard. The basketball backboard includes a display screen, a plurality of sensors configured to generate sensor data regarding a shot attempt of a user, imaging devices configured to generate image data of the shot attempt, a speaker, and a control unit. The control unit can receive (i) the sensor data from the plurality of sensors and (ii) the image data from the imaging devices. Based on the received sensor data, the control unit can determine whether the shot attempt was successful. Based on the received image data and whether the shot attempt was successful, the control unit can generate analytics that indicate characteristics of the user and the shot attempt and recommendations for improving the shot attempt for subsequent shot attempts. The control unit can provide output data representing the analytics.

A let detection system includes a sensor including an accelerometer attached to a tennis net. The sensor is in wireless communication with an umpire device able to send a message to the sensor, wherein the message causes the sensor to calibrate and begin monitoring for a let. The sensor determines a three-dimensional (3D) vector representing the gravity acting on the sensor as a baseline. When the sensor detects vertical acceleration of the net relative to the baseline and the vertical motion is above a preset threshold, the sensor automatically transmits a let notification message to the umpire device.

Systems and methods for detecting made and missed basketball shots are provided. A launcher passes basketballs to shooting locations about a basketball playing area based on user input provided at an interface to define a custom practice arrangement. A camera captures images of an underside of a rim of a basketball goal. A controller receives images from the camera, associates the images with passes from the launcher, processes the images using a machine vision model to determine which of said received images indicate a made shot, and generates a performance report indicating a number or percentage of made shots for each location in the custom practice arrangement.

An open field game arrangement includes glowing targets and provides responses, such as lights and sounds, when the targets are hit.

A game set having a flying disc, a goal mount, a target loop configured to attach to the goal mount, the target loop having a loop surface with a solid outer portion that surrounds an open middle portion, the open middle portion having at least one distinct opening, each distinct opening defining a scoring portal, and a score controller having at least one score sensor configured to detect the passage of the flying disk through each scoring portal, a vibration sensor configured to detect the target loop being impacted and wherein the score controller is configured to emit an alert when a sensor is triggered. The score controller may be further comprised of a viewing camera, microphone, game clock, scoreboard, distance verification device, loudspeaker, score buzzer, score indicator light, battery, and wireless transmitter. The score controller may communicate with a game application on a device, enabling “physical virtual” play.

A method and system for use in the game of football to determine ball placement and position, as well as first down demarcations, is described, with various embodiments configured to track the location of a football to determine its position on the field and to determine and display the first down demarcation on the field. Certain embodiments employ software to assist in performing placement determinations, distance determinations, track movement of the ball, first down markers, as well as light emitting modules along a track that extends parallel to the field.

A system for illustrating the flight of a sports ball includes a radar, an imager, and a controller. The imager is configured to image a moving sports ball. The controller is configured to (i) receive, from the imager, an image including the moving sports ball, (ii) receive, from the radar, radar data associated with the moving sports ball, (iii) determine, from the radar data, a portion of a trajectory of the moving sports hall, (iv) alter the image to illustrate the portion of the trajectory relative to the moving sports ball, and (v) output the altered image.

A system for planning, managing, and analyzing sports teams and events. The system may include a content management function for storing data. The data can pertain to a plurality of sports-related statistics and a variety of identifying data. The system and method can also include an event management function for planning and evaluating sports-related events such as practices and games. The system and method can also include a report function which can provide a variety of statistical analyses.
