An alternate reality training system for tennis is operationally coupled to a head assembly, a stand assembly, and a vertical polymer flexible rod assembly connecting the substantially polymer head assembly to the stand assembly. The vertical polymer flexible rod assembly oscillates when a ball member held in the head assembly is hit by a racket. An alternate reality software system is adapted to synchronize with oscillations to present substantially simultaneous cues for hitting a physical ball member coupled to the head member and convert associated data to a virtual ball member adapted to visually present data from hitting the physical ball member and associated user data. Data includes variables of power, accuracy, timing, trajectory, spin, and impact sweet spot from which to calculate virtual ball flight.

According to one exemplary embodiment, an apparatus, system, method and/or computer program product may provide an electronically and programmably controlled remote virtual spectator/viewer device enabling viewer interaction with an entertainment participant in an entertainment forum via an exemplary digital video camera, digital audio microphone, speaker system, and display device system coupled via at least one communications interface to a communications network to allow a remote viewer to virtually interact with and communicate with the entertainment participant in the entertainment forum. Embodiments may include a graphical user interface configured to allow control of a digital video camera, and digital microphone in the entertainment forum, by a remote user from a remote location.

A system includes a database, a camera, a tracking arrangement, and a processing arrangement. The database stores profiles including visual profiles of a plurality of sports players, each visual profile comprising identifying information for a player, each profile comprising an associated playerID. The camera captures a video stream comprising images of the sports players. The tracking arrangement captures data corresponding to trajectories of sports balls launched by the sports players. The processing arrangement coupled to the database. The camera and the tracking arrangement configured to; detect a first sports player in an image from the video stream and determine visual characteristics of the first detected sports player; match the determined visual characteristics to a first visual profile of a first profile and an associated first playerID stored in the database; and associate a first trajectory associated with a first sports shot with the first playerID.

A system includes a camera capturing images in a first field of view of a sports ball bouncing and rolling, a storage arrangement, and a processing arrangement. The storage arrangement includes a three-dimensional 3D model of a part of a sports play area and the processing arrangement is configured to: detect a pixel location of a ball in an image; determine, based on intrinsic and extrinsic calibration parameters, a camera-ball line comprising a straight line passing through the camera in the direction of the sports ball and to determine, based on the 3D model, an intersection point of the camera-ball line with the 3D model. The processor outputs the intersection point as a 3D position of the ball in the image.

A processor and camera capture data corresponding to a position of a ball and automatically adjust orientation and zoom level of the camera. The processor pre-calibrates the camera so an initial orientation is known in a world coordinate system (WCS) and so different zoom levels are associated with respective parameter values. A first position of the ball in a first image is detected and a first zoom level of the first image and intrinsic parameter values for the first zoom level are read. Based on pan and tilt relative to the initial orientation, the first orientation of the camera is determined. A 3D line through the camera and the ball in WCS is determined based on the first position, the first orientation and parameter values for the first zoom level and a 3D position is determined in WCS along the line based on information extrinsic to the camera.

A yoga under-mat to be positioned under an exercise mat, to make the exercise mat a smart mat. The yoga under-mat including a plurality of sensors to monitor a user's health data, while the user is performing exercises, and to provide data to the user.

A system includes a database, a tracking arrangement, a motion sensor device and a processing arrangement. The database stores profiles for each sports player, each profile comprising identifying information for the player and a playerID. The tracking arrangement captures shot data corresponding to trajectories of sports balls launched by the players. The motion sensor device captures motion data corresponding to a swinging motion of a player or ball striking implement. The tracking arrangement and the motion sensor device: detect a first swing of a first player from the motion data captured by the motion sensor device, the first player being associated with a first playerID; associate the first swing of the first player with a timestamp and a location; and associate a first trajectory of a sports ball from the shot data captured by the tracking arrangement to the first swing based on the timestamp and the location.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

Embodiments provide physiological measurement systems, devices and methods for cardiovascular intensity measurement. In an aspect, a wearable device receives a time series of heart rate data for a user. The time series of heart rate data can be weighted and summed according to a weighting scheme. The weighted and summed time series of heart rate data can be used to generate an intensity score indicating the cardiovascular intensities experienced by the user during a desired period of time.
