Apparatus for the assisted performance of a fitness exercise
First Claim
1. An apparatus for the assisted performance of a fitness exercise, equipped with a fitness tool configured to interact with a user to enable the user to perform a movement along a preset path overcoming the force of a resistant load, the fitness tool comprising:
- a frame;
a weight stack movably associated with the frame to define the resistant load;
at least one mobile element connected to the resistant load by a cable and movable by the user along a path overcoming the resistant load;
a detector for providing a signal representing the movement of the user;
a feedback generator for transmitting a feedback signal to the user during performance of the exercise;
a processor connected to the detector and to the feedback generator to provide the user with feedback in real time on the correctness of performance of the exercise, based on a comparison between the signal representing the movement of the user and a predetermined reference pattern representing an ideal pattern for the movement of the user corresponding to the exercise performed correctly,wherein the feedback generator comprises (i) a graphical representation of the body of the user generated by a succession of user positions and (ii) graphical elements based on the reference pattern and representative of the difference between the signal representing the movement of the user and the predetermined reference pattern,wherein the processor is programmed to display said graphical elements only when the difference between the signal representing the movement of the user and the predetermined reference pattern exceeds a predetermined tolerance margin, whereby the reference pattern is not displayed as long as the difference between the signal representing the movement of the user and the predetermined reference pattern is less than or equal to said predetermined tolerance margin.

1. An apparatus for the assisted performance of a fitness exercise, equipped with a fitness tool configured to interact with a user to enable the user to perform a movement along a preset path overcoming the force of a resistant load, the fitness tool comprising:
-
a frame; a weight stack movably associated with the frame to define the resistant load; at least one mobile element connected to the resistant load by a cable and movable by the user along a path overcoming the resistant load; a detector for providing a signal representing the movement of the user; a feedback generator for transmitting a feedback signal to the user during performance of the exercise; a processor connected to the detector and to the feedback generator to provide the user with feedback in real time on the correctness of performance of the exercise, based on a comparison between the signal representing the movement of the user and a predetermined reference pattern representing an ideal pattern for the movement of the user corresponding to the exercise performed correctly, wherein the feedback generator comprises (i) a graphical representation of the body of the user generated by a succession of user positions and (ii) graphical elements based on the reference pattern and representative of the difference between the signal representing the movement of the user and the predetermined reference pattern, wherein the processor is programmed to display said graphical elements only when the difference between the signal representing the movement of the user and the predetermined reference pattern exceeds a predetermined tolerance margin, whereby the reference pattern is not displayed as long as the difference between the signal representing the movement of the user and the predetermined reference pattern is less than or equal to said predetermined tolerance margin. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)
a graphical representation of the user corresponding to the real position of the user and without graphical elements based on the reference pattern if the difference between the value of the assessment parameter for the sensed signal and the corresponding value of the assessment parameter for the reference pattern is less than or equal to a predetermined tolerance margin; and a graphical representation of the user modified by graphical elements based on the reference pattern, to indicate the part of the body where the difference occurred, if the difference is greater than the predetermined tolerance margin.

4. The apparatus according to claim 3, wherein the processor is programmed to compare the sensed signal with the predetermined reference pattern as a function of the values adopted in the successive points in time by a first assessment parameter, representing the position adopted by the user, and by a second assessment parameter, representing a speed at which the user performs the movements.
-
5. The apparatus according to claim 3, wherein the modified representation of the user comprises coloring or highlighting on the part of the body where the difference occurred.
-
6. The apparatus according to claim 3, wherein the modified graphical representation of the user comprises graphical elements representing an ideal position of the user according to the reference pattern, in addition to the representation of the user, at least at the part of the user'"'"'s body where the difference occurred.
-
7. The apparatus according to claim 3, wherein the drive signal comprises a right-hand filling bar and a left-hand filling bar, configured to visually indicate a state of forward movement and a speed of forward movement of the user'"'"'s right and left hands, respectively.
-
8. The apparatus according to claim 7, wherein the drive signal further comprises a right-hand reference filling bar and a left-hand reference filling bar, configured to visually indicate an ideal state of forward movement and an ideal speed of forward movement of the user'"'"'s right and left hands, respectively, according to the reference pattern.
-
9. The apparatus according to claim 1, wherein the detector comprises a video camera configured to film the user during performance of the exercise or a three-dimensional movement sensor configured to sense the user'"'"'s position and movement during the exercise.
-
10. The apparatus according to claim 1, wherein the processor is set up to store the signal representing the movement of the user corresponding to the fitness exercise performed in an optimum manner, to set it as the reference pattern.
-
11. A method to assist a user in the performance of a fitness exercise using an exercise machine comprising a frame, a weight stack movably associated with the frame to define the resistant load, and at least one mobile element connected to the resistant load by a cable and movable by the user along a preset path overcoming the resistant load,
wherein the method comprises the following steps: -
