Apparatus measuring leg movement and simulating motion and forces in surroundings, employs virtual ground surface and linkages with mechanical resistances

摘要

To measure leg movement of the user, the mechanism simultaneously simulates contact with a virtual ground surface and/or associated forces. These arise from the conditions of the virtual surroundings. Mechanical resistances are used, being located in the linkages (3 - 8a/b) of the apparatus, suitably close to the hip, knee, and ankle joints, in the upper and lower leg
