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.

The application relates to an exercise history managing device. In one aspect, the device includes a map data providing unit configured to provide, to a user terminal, map data about a specific area requested by the user terminal.

The device may further include an exercise information managing unit configured to receive information about at least one of an exercise name that is input through the user terminal, a first category obtained by classifying exercises belonging to each exercise name according to a first condition, a second category obtained by classifying an exercise belonging to the first category according to a second condition, and a specific exercise belonging to the second category, store the information, and retrieve exercise information in response to a request from the user terminal.

A ball machine system comprising a ball launching system, a memory configured to store a court model that includes dimensions of a court type in relation to a three-dimensional (3D) coordinate system, an imaging system connected to the ball launching system and configured to capture a plurality of images of a court, and a processor. The processor configured to analyze the plurality of images to detect feature points in each of the plurality of images, superimpose a plurality of different transformations of the court model onto the plurality of images to generate a plurality of model fits, select as a final model fit, from the plurality of model fits, a model fit based on a degree of overlap among features of the transformed court model and the respective image, and calculate the position of the ball launching system on a playing surface of the court based on the selected final model fit and intrinsic parameters of the imaging system.

An exercise machine accessory is disclosed. In one embodiment, a resistance identifier is configured to identify resistance for an exercise machine associated with the exercise machine accessory, wherein the resistance identifier is coupled to the exercise machine. In one embodiment, a motion identifier is configured to identify exercise motion for a user of the exercise machine. In one embodiment, a communications module is configured to communicate with the user of the exercise machine, wherein the communications module is coupled to the resistance identifier and the motion identifier.

In an evaluation information provision system, subject's motion data is stored in association with attributes. When an attribute is assigned, the evaluation information provision system selects feature data from a plurality of the subject's motion data associated with the assigned attribute. The evaluation information provision system calculates a score for the assigned attribute, for the user's motion, using a statistical distance between the selected feature data and the user's motion data. The calculated score is displayed, for example, as a screen.

A positioning system includes a golf ball and a mobile terminal. The golf ball includes a battery and a transmitter configured to operate with electric power supplied from the battery and transmit a radio signal to outside of the golf ball. The mobile terminal includes a receiver configured to receive the radio signal from the golf ball and a processor configured to measure the position of the mobile terminal, and to measure the position of the golf ball based on the strength of the radio signal received by the receiver at two or more points at which the measured position of the mobile terminal differs.

Provided is a weight exercise apparatus. The weight exercise apparatus includes an exercise main body in which movement occurs according to the user's weight exercise, a sensor module detecting movement of the exercise main body, and a processor configured to control a UI unit to display a UI element indicating an exercise state of a user corresponding to the detected movement on a UI screen, wherein the sensor module includes a first laser sensor comprising a first measurement accuracy and a first measurement frequency to detect weight setting of the exercise main body when the weight plate is in a stationary state and a second laser sensor comprising a second measurement accuracy lower than the first measurement accuracy and a second measurement frequency higher than the first measurement frequency to detect movement of the weight plate when the weight plate is in a moving state.
