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.

A plurality of motion sensors capable of capturing IR video, depth video, and RGB images. Periodically emitting IR pulses. Capturing IR video, depth video, and RGB images of a user. Generating a point cloud of the user. Generating a 3D model of the user including the point cloud of the user. Inputting the IR video, depth video, and RGB images into a machine learning model. Estimating a set of joints of the user in the 3D model. Tracking, based on the estimated set of joints of the user in the 3D model, the user's motion over a period of time. Determining a number of repetitions of an exercise performed by the user. Determining a feedback value. Calculating, based on the number of repetitions and the feedback value, a user exercise score. Providing, via a graphical user interface, the user exercise score and the feedback value to the user.

A wave forming apparatus has a channel for containing a flow of water with an inlet end connected to a water supply, a floor, and spaced side walls, a first bed form or weir at the inlet end of the channel, and a second bed form in the channel downstream of the first bed form. Also disclosed is a wave forming apparatus has a channel for containing a flow of water, the channel having an inlet end connected to a water supply for supplying a flowing stream of water, a floor, and spaced side walls, and at least one oblique foil member adjustably mounted in the floor of the channel. The foils, weirs or bed form, form a standing wave.

A sand pit training bag for weight lifting and dragging exercises in the closed bag configuration and sand training in the sand pit open configuration. The sand pit training bag comprises of fasteners, attachable walls, compressed surface cover, top cover, cavity hole and cavity cover which further defines a sand pit. The open sand pit configuration is designed for proprioceptive training for athletes and the general population to recover from injuries and/or damaged ligaments, tissues, broken and fractured bones. Furthermore, the open sand pit configuration is water proof to hold liquids to define a pool of water.

Systems and methods for playing a golf game are disclosed herein. In an embodiment, a system for playing a golf game within limited confines includes a wall unit, a floor unit, and a control unit. The wall unit is configured to display a virtual portion of the golf game. The floor unit is configured to enable a physical portion of the golf game. The control unit is programmed to use first data related the virtual portion and second data related to the physical portion to enable a golfer to play a full golf hole.

A vertical jump system is described herein. The system includes a first member and a second member each having a member base that sits under a flooring, a flexible cord that extends between the first member and the second member at a desired height, fixtures coupled to the flexible cord along the first member and the second member. The flexible cord remains at the desired height when contacted. The fixtures are slidable along the first member and the second member and adjust the height of the flexible cord. This configuration allows a user to easily adjust the height of the vertical jump for training, athletics, and competition, without the cord or system components dislodging and causing injury to the user.

A physical therapy system including a boot assembly, a track assembly and a communications assembly is disclosed. The boot assembly includes a boot that is worn on the foot of the user with the knee that requires treatment. The boot includes a cushioned sole provided by a sponge within the boot. The sponge being entirely enclosed by a cover. The track assembly includes a track on which the boot is maneuvered on. The boot and the track having a low friction coefficient to allow the boot to easily slid on the track. The user may maneuver the boot in a manner that rehabilitates their knee. Within the boot is the communication assembly which includes a processor and sensors to gather data from the usage of the boot. The collected data is communicated to a mobile device allowing a user to track their therapy sessions and progress.
