A sport training method and system and a head-mounted VR device are disclosed. The method is performed by a head-mounted VR device. The head-mounted VR device is wirelessly connected to a hand-motion tracker and a foot-motion tracker. The method comprises: displaying a virtual demonstrative action; acquiring 6DOF head-motion data, 6DOF hand-motion data and 6DOF foot-motion data of the user; fusing the 6DOF hand-motion data and the 6DOF foot-motion data with the 6DOF head-motion data; calculating motion data of different parts of a human body according to the data that have been fused; and comparing the motion data of the different parts of the human body obtained by the calculation with standard sport training data of the virtual demonstrative action, and if a degree of similarity is greater than a threshold, determining that an action of a human-body part meets a training standard, and if not, displaying a corresponding prompting message in a virtual reality scene to prompt a human-body part whose action is not standard.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

An exemplary responsive training device for responding to user interaction with the device can be provided. For example, the responsive training device can be configured with a surface enclosing a compressible body. The responsive training device can further embed at least one sensor configured to sense a deformation of the compressible body and to generate a sensory output to a controller. The responsive training device can also embed a controller configured to control at least one transponder. Furthermore, the exemplary responsive training device can embed at least one transponder configured to provide an audio output and/or a visual output as a function of the sensor output.

A treadmill includes a platform where the platform includes a first side panel and a second side panel spaced apart at a distance from the first side panel, and a gap defined between the first side panel and the second side panel. The treadmill also includes a running deck contained within the platform and exposed within the gap, a first pulley connected to the running deck, a second pulley connected to the running deck opposite the first pulley, a tread belt surrounding the first pulley and the second pulley. A motor is in mechanical communication with at least one of the first pulley or the second pulley. A cover is located over the motor. A scale mechanism is incorporated into the cover over the motor.

Certain aspects of the present disclosure provide techniques for a smart putter and a putter gaming system. The smart putter may be configured with a plurality of sensors. The smart putter may be configured to process information from the plurality of sensors to determine whether a stroke has been performed by a user of the smart putter. Detecting a stroke has occurred may include detecting that the smart putter has impacted a golf ball on a field of play. The smart putter may further be configured to sign-in with a track associated with the putter gaming system. The putter gaming system may be configured to perform automatic scoring based, in part, on the stroke detection performed by the smart putter. The putter gaming system may further be configured to detected when a golf ball has been holed, indicating completion of a track.

A walking training system includes a treadmill configured to prompt a trainee to walk, a display device installed such that the trainee views the display device while walking on the treadmill, a camera configured to image the trainee at an angle of view at which a gait of the trainee is recognizable, a calculation unit configured to calculate a tilt of a body core of the walking trainee based on an image captured by the camera, and a display control unit configured to control the display device to display a body core line associated with the tilt, and an index indicating at least an end of a permissible range of a deflection of the body core line.

The present disclosure generally relates to user interfaces and more specifically to techniques for displaying user interfaces associated with physical activities. Exemplary user interfaces related to activity competitions are described. Exemplary user interfaces related to a friends list for activity sharing are described. Exemplary user interfaces associated with alerts presented to a user in response to automatically determining a boundary of a workout are described. Exemplary user interfaces associated with configuring a pace alert for a workout application are described.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A method and apparatus for automatically scoring a golf player includes detecting and recording the golf player at a golf tee pad by an identification reading device at the golf tee pad reading an identification device of a golf club that is used by the golf player. Movement of a golf ball after it is hit by the golf club is detected. A location of the golf ball when the golf ball stops is recorded and the golf player is credited with a stroke. Subsequently, each time movement of the golf ball is detected, the location of the golf ball is updated and the golf player is credited with another of the stroke.

A smart mirror can show live or recorded streaming video of an instructor performing a workout in a package that is attractive and unobtrusive enough to hang in a living room. The smart mirror includes a mirror surface with a fully reflecting section and a partially reflecting section. A display behind the partially reflecting section shows the video when the smart mirror is on and is almost invisible when the smart mirror is off. The smart mirror also has a speaker, a microphone, and a camera to enable a user to view the video content and interact with the instructor. The smart mirror may connect to the user's smart phone, a peripheral device (e.g., a Bluetooth speaker) to augment user experience, a biometric sensor to provide biometric data to assess user performance, and/or a network router to connect the smart mirror to a content provider, an instructor, and/or other users.
