Systems and methods for providing a distortion-free pool-surface display beneath a swimmer. In one embodiment, projectors are positioned below a water level at opposite walls of a pool, and are configured to project images to a display surface at the bottom of the pool beneath a swimmer. A camera is used to view images projected by the projectors and to provide corresponding image data to an image correction platform on a graphics processing unit (GPU). The image correction platform identifies distortions in the images, generates image corrections that counter the identified distortions, and applies the corrections to subsequently projected images. The image correction platform also generates image adjustment that cause overlapping portions of the projected images to match seamlessly. The projected images may provide immersive experiences, coaching/training interfaces or other interactive displays.

A method of predicting the likelihood of a post T-off golf swing or consecutive swings resulting in a ball being sunk in a hole; the method utilizing communication equipped cameras or communication equipped laser rangefinders at known locations to determine accurate ball lie information. Transmission of this location information in real time to a processing facility linked to a database of historical play information incorporating at least ball position information and golf course in order to calculate odds of success of the upcoming swing and/or subsequent swings.

A system for ankle rehabilitation includes a motorized platform arranged to hold an ankle of a subject to be rehabilitated; a first sensor module arranged to detect signals representing movement intention of the ankle on the motorized platform; a second sensor module arranged to detect signals representing actual movement of the ankle on the motorized platform; and a processor arranged to process the signals detected by the first sensor module and the signals detected by the second sensor module, for control of movement of the motorized platform.

A method includes causing display, during a first time period and via a first set of multiple smart mirrors, of live video depicting at least one user associated with the first set of multiple smart mirrors, without displaying a workout video. The method also includes causing display, during a second time period following and mutually exclusive of the first time period, and via a second set of multiple smart mirrors, of a workout video and a representation of at least one user associated with the second set of smart mirrors. The method also includes causing display, during a third time period following and mutually exclusive of the second time period, and via a third set of multiple smart mirrors, of live video depicting at least one user associated with the third set of multiple smart mirrors.

A system (100) for training a subject such that the subject includes an input unit (102) having a number of sensors (112) that are configured to detect a number of physiological parameters of a user. A processing unit (104) is configured to receive the number of physiological parameters for comparing the number of physiological parameters with a set of predefined physiological parameters to generate a baseline signal (116A). An output unit (106) is configured to generate an instruction signal (118A) upon receipt of the baseline signal (116A) and a regulating unit (108) that is configured to regulate a speed of a game associated with a gamification engine (110) and a speed of an exercising apparatus (200) upon receipt of the instruction signal (118A).

During a first time period and for a first user, a second user is automatically selected based on competitive data of the first user and competitive data of the second user, and a workout selection is sent to cause a video of a workout to be displayed during a second time period on a smart mirror of the first user and a smart mirror of the second user. During the second time period, a live stream of the first user exercising is displayed at the smart mirror of the second user, and a live stream of the second user exercising is received and displayed at the smart mirror of the first user. During the second time period, a performance score of the first user and a performance score of the second user is displayed at the smart mirrors of the first user and the second user.

A system includes a processor configured for leveraging reference ball flight data associated with an individual and a reference club having a reference loft angle to compute predicted ball flight characteristics for other candidate golf clubs having loft angles different from the reference loft angle. The predicted ball flight characteristics include predicted distances of golf shots the individual is expected to make using the candidate golf clubs that can further accommodate a computed recommendation of optimal loft angles for a consistently gapped golf club set.

A multidimensional exercise control system is disclosed herein. In one embodiment, a control system of an exercise machine comprises a memory device storing instructions, a user interface for presenting a video game with an avatar, and a processing device operatively coupled to the memory device and the user interface. The processing device is configured to execute the instructions to receive sensor data from a sensor operatively coupled to an exercise machine, wherein the sensor data comprises one or more measurements; responsive to the one or more measurements, cause the avatar to change a position in the video game; compare the one or more measurements to a target threshold; determine whether the one or more measurement exceed the target threshold; and responsive to determining that the one or more measurements exceed the target threshold, cause the user interface to present a modification to the video game.

Provided is a device for pitch detection within user-defined zones. The device detects a first gesture at a first height based on first output from all or some sensors, and detects a second gesture at a second height based on second output from all or some sensors. The device sets a top and bottom of the user-defined zone based on the first height and the second height, and tracks a location of an object relative to the user-defined zone based on third output, from a subset of sensors, that is generated in response to the object moving over or under the subset of sensors. The device discards output generated from two or more sensors that are not adjacent, measurements from adjacent sensors that differ by more than a distance threshold, and/or output from adjacent sensors with timestamps that differ by more than a time threshold.

Systems and methods are disclosed for generating a 3D avatar using a biomechanical analysis of observed actions with a focus on representing actions through computer-generated 3D avatars. Physical quantities of biomechanical actions can be measured from the observations, and the system can analyze these values, compare them to target or optimal values, and use the observations and known biomechanical capabilities to generate 3D avatars.
