Abstract: Embodiments relate to determining a speed of a multidimensional motion of an athlete in a global coordinate system based on multidimensional acceleration data from a multidimensional accelerometer placed at a movable limb of the athlete, the movable limb being at least one of translatory and rotatable, and the movable limb defining a local coordinate system. Based on the multidimensional acceleration data, at least one correction quantity may be determined taking into account a rotation of the local coordinate system relative to the global coordinate system during the multidimensional motion. The speed of the multidimensional motion may be determined based on an integration of the multidimensional acceleration data and in consideration of the at least one correction quantity.

Abstract: In a method for reconstructing a motion of an object from a sequence of motion pattern segments of a computer model of the object, a motion transition between an initial motion state and a final motion state of the object in a time interval of the motion is captured based on position data of the at least one sampling point which is received from the position marker. Further, at least one motion pattern segment corresponding to the motion transition is selected from a plurality of motion patterns of the computer model which are stored in a database such that the selected motion pattern segment leads with sufficient probability from the initial motion state to the final motion state for the time interval. Furthermore, an image of the motion of the object for the time interval is reconstructed using the initial motion state and the selected motion pattern segment.
