First Claim
Patent Images
1. A 3D monocular tracking system for the rehabilitation of a patient'"'"'s upper limbs, characterized by comprising:
- a) a handle or gripper comprising a cylindrical gripper and two colored spheres, one at each end of the gripper (FIG. 1);
b) a computational vision system comprising a video camera to determine, through the tracking of the handle balls, the position and 3D movement of the patient'"'"'s arm and/or, as well as its rotation around 3 orthogonal axis,c) a Gesture Therapy software comprising a program for 3D tracking of the two colored spheres in the handle, and a set of games oriented to daily life activities, which include different difficulty levels to evaluate the patient'"'"'s progress at every game;
d) a processor configured for;
selecting between the set of games, an appropriate game to the patient;
calling the game;
providing the required algorithms to determine the position and 3D movement of the patient'"'"'s hand;
recognizing the position and 3D movement of the patient'"'"'s arm and/or hand;
controlling the game, based on the position and 3D movement of the patient'"'"'s arm and/or hand;
adapting to the patient according to his (her) condition in the therapy progress;
automatically alternating, for example, the working space for the limb'"'"'s movement;
detecting the pressure when the patient tights/loses the joystick by a pressure sensor incorporated therein, thereby promoting the rehabilitation of the hand'"'"'s movements.e) a display apparatus configured to show 3D virtual environments that the patient can interact.

8. A home self-directed therapy method for patients having upper limbs'"'"' movement disability, preferably one having suffered from stroke, characterized by comprising:
-
offering a patient a monocular 3D tracking system for the rehabilitation of a patient'"'"'s upper limbs; selecting, from the set of games, an appropriate game for the rehabilitation of the patient; calling the game; recognizing the position and 3D movement of the patient'"'"'s arm and/or hand; showing 3D virtual environments, visible for the patient, wherein the 3D virtual environments respond to the 3D movement of said patient'"'"'s arm and/or hand; adapting to the patient according to his (her) condition and therapy progress;
automatically alternating, for example, the working space for the limb'"'"'s movement;repeating the above steps during the necessary period of time. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
