A virtual play system is composed of a mobile terminal 2 worn by a player P, a virtual play display terminal 6 provided with a display unit 86, and a cloud server 4 capable of communicating with the mobile terminal 2 and the virtual play display terminal 6. The mobile terminal 2 includes a data analysis unit that transmits first measurement data obtained by measuring and quantifying an actual motion of player P during play and second measurement data obtained by measuring and quantifying the motion of player P during simulated play to the cloud server 4, and the cloud server 4 includes a virtual play data generation unit that calculates virtual play data based on the first measurement data and the second measurement data, and the virtual play display terminal 6 displays the virtual play data.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

An interactive electronic trampoline assembly is made up of a frame, legs, a trampoline mat, a plurality of bias members to secure the trampoline mat to the frame, and a sensor to sense movement of the trampoline mat. A handlebar may also be connected to the frame. A control module may be removably secured to the assembly adjacent the frame. The control module may have a speaker, a power source, a controller, lights and control buttons. The sensor may also be housed in the control module. Different lights and sounds are output based on an input to the controller, the game being played and input received by the sensor.

An embodiment of the present disclosure of a rucking system that includes a stackable plate assembly having a first plate and a second plate.

The present invention measures jump heights using an IMU sensor module slipped in a pocket of a removable side ankle mount clip placed over any low, mid or high tops ankle athletic running shoe. A micro-processor in the IMU sensor module converts analog jump height data collected with real time digital signal processing to digital data sent to specialized algorithms loaded in a RF paired smartphone to refine the digital data to accurately calculate the height of the jump. The clip has two downward spaced legs joined by a curved arch at the top with a first leg being flexible and fitting snugly against a wearer's ankle below the fibula bone with the curved arch resting over the shoe's collar. The second leg has a foot extending outwardly from the curved arch to form a pocket with a top opening to receive and snugly hold the module.

Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

Bilateral vestibular loss is a chronic condition of which the causes can be ototoxic, infectious, traumatic, autoimmune or congenital. An object of the invention is to improve the effectiveness of a vibrotactile feedback arrangement. The current invention provides a vibrotactile feedback arrangement for use arranged to a human body, comprising: a sensor arranged for sensing a current attitude of the human body relative to the environment; tactile actuators arranged for allowing the human body to perceive an attitude deviation; an elongated carrier for holding the tactile actuators and the sensor in tactile communication with the human body and for holding the tactile actuators and the sensor substantially fixed relative to the human body; and a processing unit configured for: receiving the current attitude from the sensor; determining the attitude deviation based on comparing a desired attitude of the human body with the current attitude; and transmitting an actuation signal to one or more of the tactile actuators based on the attitude deviation; wherein the tactile actuators are arranged to the carrier such that, when the carrier is used, the tactile actuators are arranged substantially in a reference plane; wherein the reference plane is functionally perpendicular to a central axis of a torso of the human body and the reference plane intersects the torso to define a circumference, wherein the tactile actuators are arranged to the circumference; and wherein the carrier comprises stretchable material such that the relative distance between the tactile actuators and/or between the tactile actuators and the sensor is maintained independent of the length of the circumference.
