This invention is related to a mechanism to be used to balance the weight of a patient or a sportsman in rehabilitation or sport based equipment. The purpose of the weight balancing mechanism subject to the invention is to prevent the legs carry the entire weight of a patient or a sportsman during the walking therapy on a treadmill by carrying a portion of their weight. The other purpose of this invention is to adjust the amount of the weight need to be carried. During the phases of walking due to changing the tension of the rope, no change will be occured in the weight of the user is the final purpose of the invention. In order to reach this aim, a mechanism is developed for adjusting the tension of the rope in the light of the rope movements.

A balance training system includes: a load detection part including a mounting surface for supporting soles of feet of a trainee in a standing state, the load detection part detecting a load received from the trainee riding on the mounting surface; a mobile body to which the load detection part is attached; a control unit that calculates a position of a center of gravity of the trainee based on the load detected by the load detection part and controls a movement of the mobile body based on a change of the position of his/her center of gravity; and a vibrator provided so as to be able to apply a vibration to the trainee. The control unit vibrates the vibrator so as to prompt the trainee to move the position of his/her center of gravity from a current position of the center of gravity to an expected position thereof.

An information processing apparatus includes a processor and a memory with instructions thereon. The instructions upon execution by the processor, causes the processor to: sequentially sense a movement of a body of a user; present, to the user, an avatar corresponding to the user, rather than a photographed image of an appearance of the user, based on a result of the sensing so that the user perceives a shape of a surface of the body of the user; determine a position of a figure object to be drawn that serves as a guide for movement of the body of the user in association with the avatar based on the result of the sensing; and display the figure object at the determined position.

A motorized lifting rack that selectively lifts and lowers a barbell through linear actuators is provided. The powered lifting rack can engage a barbell at floor level. The linear actuators can also selectively raise and lower safety bars design to “spot” the barbell for a single user. The powered lifting rack is embodied in a system that includes a platform that the safety bars can nest in. The platform provides a plurality of actuating benches for a user of the barbell to utilize.

A rehabilitation assistance apparatus 1 includes: an acquisition unit 211 configured to acquire at least one of an image of a subject who is doing exercise for rehabilitation, audio of the subject, and biological information of the subject; a calculation unit 212 configured to calculate a fatigue level of the subject based on at least one of the image, the audio, and the biological information; a generation unit 213 configured to generate feedback information related to the rehabilitation, based on the fatigue level; and an output unit 23 configured to output the feedback information.

An electronic apparatus is provided. The electronic apparatus may include a display; a camera; a memory in which reference information associated with a content that provides information is stored; and a processor may be configured to obtain an image photographing a user through the camera while the content is provided through the display; obtain context information associated with the user based on the image; identify an execution status of the user associated with the information provided by the content by comparing the obtained context information and the reference information; and control an output state of the content based on the execution status of the user.

A ball machine comprising an imaging system to capture image data and a processor configured to, for a frame of the image data, analyze the image data using a neural network to detect a plurality of persons, determine a coordinate position on a playing surface of each of the plurality of detected persons, extract features of each of the plurality of detected persons, generate a first set of feature vectors corresponding to the plurality of detected persons, associate a first feature vector to the coordinate position on the playing surface of a first detected person to generate a first unique identifier, associate a second feature vector to the coordinate position on the playing surface of a second detected person to generate a second unique identifier, and control the ball machine to launch balls based on first settings corresponding to the first unique identifier and second settings corresponding to the second unique identifier.

The training machine assembly comprises at least one control device and at least one training resistance. Each of the at least one training resistance comprises at least one training resistance value, such as a force applied towards the user contact element, e.g. a handle. The training resistance value can also comprise a function or a vector, for example a function linking a speed of movement of a user and/or a user contact element and a force applied against said movement. The control device can be a control device for controlling the training machine assembly. The training resistance can comprise an actuator. The actuator can comprise an electric motor. The training resistance can comprise a weight. The training resistance can comprise another element configured to provide a resistance against a movement of the user. The training machine assembly can comprise at least one camera.

An immersive upper limb rehabilitation training system includes a dual-arm rehabilitation robot, a base, a position tracker, a VR headset, a force-feedback glove, a host computer control center and passive compliant end-effectors. The dual-arm rehabilitation robot is mounted on the base, and drives an arm of a patient to move through two passive compliant end effectors. The visual sensor is used for recording a motion of an upper limb of the patient and feedback-controlling a motion of the dual-arm rehabilitation robot. The position tracker is used for real-time collecting position and posture information of the arm and transmitting it to the upper computer control center. The two passive compliant end-effectors are respectively worn on a forearm and an upper arm of the patient. The upper computer control center is used to provide a quantitative index and control a display of a training screen.
