An example of a posture monitoring and correction system monitors user's posture and induces corrective action. The system includes a wearable monitoring group that acquires posture data with a group of sensors. A processing module is in signal communication with the wearable monitoring group to receive the posture data and compute a risk of injury parameter. Correction elements induce a corrective action in the user's body upon the risk of injury indicator parameter exceeding a threshold level.

An exercise assist method includes receiving a user input signal comprising exercise setting information from an external device; measuring, based on the user input signal, a joint angle of a hip joint of a user wearing an exercise assist device configured to assist a user in performing a leg movement; and controlling torque of the exercise assist device to be applied to a leg of the user based on the measured joint angle and the exercise setting information.

The present invention relates, in various embodiments, to improved simulation technology for use with a stationary training system. In some embodiments, this includes use of sensors, for example, wearable sensors, to control simulation parameters (such as display and/or performance parameters). For example, in some embodiments, a body worn sensor, such as an accelerometer and/or gyroscope, is used thereby to infer body position attributes of a user and, in response, configure one or more simulation parameters. These may include, for example, display parameters (for example, whether a simulated avatar is seated or standing) and/or performance parameters (for example, simulated wind resistance).

A 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 an element configured to provide a resistance against a movement of the user. The training machine assembly can comprise at least one camera.

A walking training system includes a leg orthosis fitted to a leg of a user, a pulling member coupled to the leg orthosis, a first drive mechanism configured to apply pull force to the pulling member, according to walking motion of the user, a holding device that holds the pulling member at a holding level, at a point between a coupling point of the leg orthosis and the first drive mechanism, and a second drive mechanism configured to change the holding level of the pulling member held by the holding device, according to the walking motion of the user.

Disclosed are a system and a method for adjusting an image based on physiological information and a posture. The method includes following steps: obtaining a physiological information value corresponding to a user by a processor through a wearable device; obtaining a posture value corresponding to the user by the processor through an image capturing device; and adjusting the image by the processor based on at least one of the physiological information value and the posture value correspondingly.

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.

The present invention relates to a virtual reality-based task-oriented gait training system and method, in which the virtual reality-based task-oriented gait training system according to the present invention includes a gait detection unit that detects a walking movement of a trainee, a projector unit that projects virtual walking environment information for inducing a gait training of the trainee, and a control unit that executes a walking training program to change the virtual walking environment information according to the detected walking movement of the trainee, in which the virtual walking environment information includes a background constructing a virtual space and a walking training object appearing in the virtual space, and the gait training object includes a virtual obstacle for disturbing the walking movement of the trainee according to a preset level of difficulty or a gait inducing object for inducing gait of the trainee with a predetermined stride length. According to the present invention, there is an advantage that the trainee can perform gait training with interest and receive trainee-customized treatments through real-time interaction in virtual reality implemented closer to a real ground walking environment.

An exercise apparatus includes a motor, a cable coupled to the motor, an exercise attachment coupled to the cable such that the motor is operable to exert force on the exercise attachment via the cable, a display screen, and a controller. The controller is programmed to control the motor based on simulated progress through a virtual environment, determine a beam direction based on a cranial orientation of the user of the exercise apparatus, generate a graphical visualization of the virtual environment by casting a virtual light beam along the beam direction, and cause the display screen to display the visualization.

A method for adjusting an image based on physiological information and a posture includes following steps: obtaining a physiological information value corresponding to a user by a processor through a wearable device; obtaining a posture value corresponding to the user by the processor through an image capturing device; and adjusting the image by the processor based on at least one of the physiological information value and the posture value correspondingly.
