摘要： The present invention provides a method and apparatus for tracking hand and/or wrist rotation of a user performing exercise. An aspect of the present invention proposes a method of tracking hand and/or wrist rotation of a user performing an exercise, wherein the user wears a marker on his/her hand, the method comprising the steps of: acquiring a first image and a second image of the marker by means of a camera when the hand is in a first posture and a second posture respectively; deriving the angle change of the hand and/or wrist from the change from the first posture to the second posture, based on the first image and the second image and the type of the exercise that the user is performing; and outputting the angle change of the hand and/or wrist, wherein the marker approximates a rectangular block, the marker has an opening for accommodating the palm(s) of the user and the side of the marker along the direction perpendicular to the palm is substantially shorter than two other sides. In this way, a single hand-worn marker is adequate for hand/wrist rotation tracking, so that the system implementation may be simplified and the cost for markers or other accelerometers can be saved.
