Disclosed are systems, devices, and methods for using virtual or augmented reality in sports training, an exemplary method including detecting a position of a real ball, determining a trajectory for a virtual ball, the trajectory intersecting with the detected position of the real ball, displaying, by a virtual or augmented reality display device, a virtual pitch of the virtual ball along the trajectory intersecting with the detected position of the real ball, detecting, by a sensor included in a glove worn by the player, vibrations caused by an impact between a bat held by the player and the real ball, determining whether a level of the vibrations is within a predetermined range, sending a signal, to a speaker, when the level of the vibrations is within the predetermined range, to cause the speaker to emit an audible tone, and emitting, by the speaker, the audible tone.

Generally discussed herein are devices, systems, and methods for smart weight-lifting devices. A weight-lifting pin may be configured for insertion into a weight plate of a weight-lifting machine, the weight-lifting pin comprising a radio transmitter, a movement sensor, and a distance sensor.

Light emitting clothing is disclosed. The light illuminating clothing has a plurality of light-emitting straps and a plurality of non-light-emitting straps. The straps are secured to metal rings to hold the straps in a desired configuration. The light-emitting straps have two light tubes disposed in parallel orientation with a space between the light tubes. LEDs are disposed at the ends of the light tubes and a control pack having batteries and a microprocessor is disposed at an end of the strap. The light emitting clothing may be in the shape of a harness to fit over top of standard clothing or may itself be embedded articles of clothing.

A training system based on mobile technology and kinematics of human motion characterizes, analyzes, and supplies feedback to a user based on the user's movements. The training system includes a garment having a sensor control module connected to multiple sensor nodes via electrically-conductive fabric running along parts portions of the garment. The sensor module/nodes can communicate through the conductive fabric. The sensor nodes acquire motion and/or physiologic readings that are wirelessly transmitted to a mobile computing device that runs an application that analyzes the data and provides visual (e.g., graphs, 3D avatar) and audio feedback (e.g., voice prompts). Vibration motors and LEDs/electroluminescent fabric in the garment also provide notifications and alerts. The triple layer of garment, conductive fabric, and sensor module/sensor node are sealed against contaminants, allowing the garment to be washable.

A training device or apparatus for improving performance speed. In one embodiment, the training device includes first and second surfaces disposed in an opposing manner and defining a space therebetween. The space can allow at least one body part of an athlete to cyclically travel between the first and second surfaces in a plane that intersects both of the first and second surfaces. The athlete can be supported such that the body part is substantially free from external resistance along a direction of travel within the plane. In this way, repeated movement of a body part can occur between the first and second surfaces without fatiguing muscles due to external resistance, thereby lengthening the duration of the training session. The at least one body part can include the feet of the athlete.

A system for imparting a variable user force to a user, the system comprising: a line guide arrangement, including at least one moveable line guide which may move in both directions along a linear axis; wherein a force arrangement is arranged to apply at least one internal force to the at least one moveable line guide, wherein the at least one internal force opposes the motion of the at least one moveable line guide in a first direction along the linear axis; a member with which the user may interact so that the user force is applied to the user through the member; a line, having a distal end and a proximal end, with the distal end of the line attached to the member, the line being continuously threaded around the line guide arrangement; the system further comprising a line adjustment arrangement, wherein: the line adjustment arrangement is attached to the line, or is connected to move a component of the line guide arrangement; when the line adjustment arrangement is in a locked mode, there is a first ratio between distance moved by the member and distance moved by the force arrangement; and the line adjustment arrangement is operable to remove/introduce line between an entry point and the member, or actively move the component of the line guide arrangement, to alter the ratio between distance moved by the member and distance moved by the force arrangement during movement of the member.

The two-part system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and when an infrared signal is received the microcontroller triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

A sports simulator calculates spin of a sports object using image analysis. A velocity vector is also calculated. These are combined to produce a predicted future trajectory of the sports object. In one embodiment, the sports object is a golf ball and the sports simulator simulates golf.

A somatosensor device comprises a handle (10) having a hollow free end (130) to form a cavity (133) with an opening in a tail end surface (131); a wireless charging circuit board (30) overlapped on the tail end surface (131); a tracker (50) fixed on the wireless charging circuit board (30) and electrically connected with same, the tracker (50) inserted into the cavity (133) as the wireless charging circuit board (30) is overlapped on the tail end surface (131); and an end cap (70) covered on the free end (130) of the handle(10), so as to seal the cavity (133) with the opening in the tail end surface (131). The configuration takes account of the sealability and wireless charging.

Disclosed are devices, systems, and methods for training a player to hit a ball at a target, an exemplary net for use in such a system includes one or more display elements configured to display a target towards which the player should hit the ball, and one or more sensors configured to detect an impact between the ball and the net, and determine whether the detected impact between the ball and the net is at the target.
