one or more data processing devices operatively coupled to the force measurement assembly and the at least one visual display device, the one or more data processing devices configured to receive the one or more signals that are representative of the forces and/or moments being applied to the surface of the force measurement assembly by the subject and to compute one or more numerical values using the one or more signals, the one or more data processing devices being configured to control the movement of the at least one displaceable visual indicator towards the at least one target or marker by using the one or more computed numerical values, the one or more data processing devices being further configured to determine a motion profile for the displaceable background or the virtual reality scene in the second screen portion of the output screen of the at least one visual display device in accordance with at least one of;
(i) a movement of the subject on the force measurement assembly, (ii) a displacement of the force measurement assembly, and (iii) a predetermined value set by a system user.

Abstract
A force measurement system includes a force measurement assembly configured to receive a subject thereon; at least one visual display device having an output screen, the output screen of the visual display device configured to at least partially surround the subject disposed on the force measurement assembly, the visual display device configured to display at least one target or marker and at least one displaceable visual indicator, and/or one or more virtual reality scenes, on the output screen thereof; and one or more data processing devices operatively coupled to the force measurement assembly and the visual display device. A method for training a subject disposed on a force measurement assembly is also disclosed herein. A force and motion measurement system including a force measurement assembly, a motion detection system, at least one visual display device, and one or more data processing devices is additionally disclosed herein.

11. A method for training a subject disposed on a force measurement assembly, the method comprising the steps of:
-
providing a force measurement assembly configured to receive a subject, the force measurement assembly including; at least one surface for receiving at least one portion of the body of the subject; and at least one force transducer, the at least one force transducer configured to sense one or more measured quantities and output one or more signals that are representative of forces and/or moments being applied to the at least one surface of the force measurement assembly by the subject; providing at least one visual display device having an output screen, the output screen of the at least one visual display device configured to at least partially surround the subject disposed on the force measurement assembly, the at least one visual display device configured to display at least one target or marker and at least one displaceable visual indicator in a first screen portion of the output screen together with a displaceable background or a virtual reality scene in a second screen portion of the output screen; providing a data processing device operatively coupled to the force measurement assembly and the at least one visual display device, the data processing device configured to receive the one or more signals that are representative of the forces and/or moments being applied to the at least one surface of the force measurement assembly by the subject and to compute one or more numerical values using the one or more signals; positioning the subject on the force measurement assembly; sensing, by utilizing the at least one force transducer, one or more measured quantities that are representative of forces and/or moments being applied to the at least one surface of the force measurement assembly by the subject and outputting one or more signals representative thereof; converting, by using the data processing device, the one or more signals that are representative of the forces and/or moments being applied to the at least one surface of the force measurement assembly by the subject into one or more numerical values; displaying the at least one target or marker and the at least one displaceable visual indicator in the first screen portion of the output screen together with the displaceable background or the virtual reality scene in the second screen portion of the output screen such that at least a part of the second screen portion of the output screen circumscribes an area of the first screen portion comprising the at least one target or marker; and controlling, by using the data processing device, the movement of the at least one displaceable visual indicator towards the at least one target or marker by using the one or more computed numerical values. - View Dependent Claims (12, 13, 14, 15, 16)
