A golf instruction method, apparatus and analytics platform for determining the state of a putted golf ball relative to a target using information about the golf ball and external variables and remotely displaying the same, comprising a base unit, a mobile device or terminal, and an associated computer program including an analytics engine for analyzing a user's performance. The computer program determines whether and how a putted golf ball has missed said target and then stores, aggregates and displays that information for a user. The analytics engine is operable to aggregate data, analyze data and then correlate a user's actual skill proficiency to ball performance.

A machine implemented method for simulated sports training includes the steps displaying a simulated environment having one or more virtual objects of a sporting event; displaying to a user a moving object in the simulated environment in accordance with object path data representing an object path and conditions of motion of the moving object as a function of time; correlating soundscape data to the object path data, the soundscape data being dependent on both object path of the moving object in the object path and the conditions of motion; and outputting sound to the user based on the correlated soundscape data either before or during displaying to the user the moving object, thereby providing spatial auditory clues for assisting tracking eye movements of the user to train the user to anticipate or recognize a trajectory of the moving object.

The invention relates to spectacles, systems and methods for visibility enhancement, including by glare suppression. The spectacles, systems and methods for visibility enhancement includes spectacles and a spectacle lens having a liquid crystal cell (LC), the transmission (TR) of which may be varied by a suitable control and the liquid crystal cell (LC) designed so that the transmission (TR) of the liquid crystal cell (LC) may be switched between high and low transmission states. The liquid crystal cell (LC) includes a control for regulating the times of the state of high transmission (T.sub.on) of the liquid crystal cell (LC) such that the temporal position of the times of the high transmission state (T.sub.on) within a period of times of the high transmission state (T.sub.on) and times of the low transmission state (T.sub.off) may be altered continuously or discontinuously; and/or the duration of a period of times of the high transmission state (T.sub.on) and times of the low transmission state (T.sub.off) may be altered continuously or discontinuously. Such changes may be determined by a secret coding key.

A virtual reality (VR) system comprising a head-mounted display (HMD) and handheld controller set is enhanced to provide a more realistic end user VR experience, e.g., for boxing or other interactive training. In this approach, and in lieu of simply establishing a boundary area for the VR experience, the user also maps a position of a real-world object into a reference frame of the VR environment. This mapping is facilitated using the handheld controller itself, e.g., as positioned in a backwards-facing manner on the user's forearm. The real-world object is then simulated in the 3D VR environment as rendered by the VR HMD, and the user interacts with the real-world object (or its simulation) to provide a more enjoyable and useful interactive experience.

Example systems, devices, media, and methods are described for evaluating movements and physical exercises in augmented reality using the display of an eyewear device. A motion evaluation application implements and controls the capturing of frames of motion data using an inertial measurement unit (IMU) on the eyewear device. The method includes presenting virtual targets on the display, localizing the current eyewear device location based on the captured motion data, and presenting virtual indicators on the display. The virtual targets represent goals or benchmarks for the user to achieve using body postures. The method includes detecting determining whether the eyewear device location represents an intersecting posture relative to the virtual targets, based on the IMU data. The virtual indicators display real-time feedback about user posture or performance relative to the virtual targets.

Disclosed is a belay device for climbing including an automatic winder including a pulley and a rope. The device includes an electric motor configured so as to apply a torque to the pulley and an encoder coupled to the pulley. The motor is controlled using the encoder according to the rotation of the pulley so as to modulate the torque applied to the pulley according to at least: —an assistance mode in which the torque applied by the servomotor to the pulley drives a pulling of the rope which assists the climber in his climb; and —a fall mode in which the torque applied by the servomotor to the pulley blocks a fall of the climber or slows it to a speed less than 3 m/s. Also disclosed is a climbing game system with virtual or augmented reality using such a belaying device.

A method synchronizes headset output signals of an extended reality headset having a headset receiver, wherein the extended reality headset is worn by a user when the user is operating a piece of exercise equipment having an exercise transmitter to transmit an exercise output signal. A motion sensing detector detects motion of the user, wherein the motion sensing detector includes a motion transmitter to transmit a motion signal. The method begins with receiving the exercise output signal from the exercise transmitter using the headset receiver. The motion signal is then received from the motion transmitter using the headset receiver. The headset output signals are then synchronized as they are emitted by the extended reality headset to match the exercise output and motion signals such that the user can sense the headset output signals congruently with what the user can feel when exercising on the piece of exercise equipment.

A force measurement system and a motion base used therein is disclosed herein. The force measurement system includes a force measurement assembly configured to receive a subject, a motion base for displacing the force measurement assembly, and one or more data processing devices operatively coupled to the force measurement assembly and an actuation system of the motion base. The motion base includes a support structure; a displaceable carriage coupled to the force measurement assembly; and an actuation system, the actuation system including one or more actuators operatively coupling the displaceable carriage to the support structure, the one or more actuators configured to displace the displaceable carriage with the force measurement assembly relative to the support structure, the displaceable carriage being suspended below a portion of the support structure.

A method includes determining a customized action routine for a person to carry out in a virtual world, where the person is wearing a virtual reality (VR) headset. Objects associated with events from the routine are presented to the person in a virtual world via the VR headset; and aspects of the person's virtual interaction with the object in the virtual world are rendered on the VR headset. The person's virtual interactions with virtual objects is analyzed and used to determine, in real time, one or more next events for said routine.

A method can include determining physical characteristics of a trainee, adjusting a target zone based on the physical characteristics, adjusting one or more parameters of a delivery device based on the physical characteristics, projecting an object toward the target zone along a trajectory, and scoring a performance score of the trainee to track the object along a portion of the trajectory. A method can include projecting an object toward a target zone along a trajectory, a trainee attempting to impact the object at an appropriate location with a desired impact location of a sport tool, capturing imagery that contains the object at the appropriate location and the desired impact location of the sport tool, determining horizontal and vertical distances between the desired impact location and the object arriving at the appropriate location, and scoring a performance based on the horizontal and vertical distances.
