Mechanical audio and haptic feedback deflection beam
Devices and methods for detecting joint motion of a user. In particular embodiments, devices may comprise a deflectable beam coupled to a user via adhesive pads located between the neck and shoulder of the use. Audio and haptic feedback can be provided to the user when the deflectable beam deflects due to motion of the joint.
1. A device for detecting joint motion of a user, the device comprising:
a deflectable beam comprising a first end and a second end;
a first support coupled to the deflectable beam proximal to the first end;
a second support coupled to the deflectable beam proximal to the second end;
a first adhesive pad coupled to the first support; and
a second adhesive pad coupled to the second support, wherein:
the deflectable beam has a length extending between the first end and the second end;
the deflectable beam has a width perpendicular to the length;
the deflectable beam has a curved profile across the width of the deflectable beam;
the deflectable beam is a metal beam;
the deflectable beam is configured to provide audio and haptic feedback to the user when the deflectable beam is deflected; and
the haptic feedback results from a decreased stiffness of the deflectable beam.
2. The device of claim 1 wherein the device is configured to be coupled to a user in an area proximal to a joint.
3. The device of claim 2 wherein the deflectable beam is configured to deflect when the joint is moved by the user.
4. The device of claim 2 wherein the joint is a shoulder joint.
5. The device of claim 2 wherein the joint is a neck joint.
6. The device of claim 1 wherein:
the first adhesive pad is coupled to the first support via a first snap member and a second snap member; and
the second adhesive pad is coupled to the second support via a third snap member and a fourth snap member.
7. The device of claim 6 wherein:
the first snap member is inserted into a first cavity in the first support;
the second snap member is coupled to the first adhesive pad;
the third snap member is inserted into a second cavity in the second support;
and the fourth snap member is coupled to the second adhesive pad.
8. The device of claim 1 wherein the audio feedback is in the audible range for a human.
9. The device of claim 1 wherein the deflectable beam is configured to provide secondary audio feedback when the deflectable beam moves from a deflected position to a straight position.
10. The device of claim 1 wherein the deflectable beam:
the length is between two inches and five inches;
the width is between 0.15 inches and 0.35 inches; and
the deflectable beam has a thickness less than 0.010 inches.
11. A method of detecting movement of a joint of a user, the method comprising:
coupling a device comprising a deflectable beam to an area proximal to the joint; and
moving the joint an amount sufficient to cause a deflection of the deflectable beam,
wherein:
the deflectable beam has a length extending between the first end and the second end;
the deflectable beam has a width perpendicular to the length;
the deflectable beam has a curved profile across the width of the deflectable beam;
the deflectable beam is a metal beam;
the deflection of the deflectable beam produces an audio and haptic feedback to the user; and
the haptic feedback results from a decreased stiffness of the deflectable beam.
12. The method of claim 11 wherein coupling the device comprising the deflectable beam to the area proximal to the joint comprises coupling adhesive pads to the user.
13. The method of claim 11 wherein the joint is a shoulder joint.
14. The method of claim 11 wherein the joint is a neck joint.
15. The method of claim 11 wherein the audio feedback is in the audible range for a human.
16. The method of claim 11 wherein the deflectable beam is configured to provide secondary audio feedback when the deflectable beam moves from a deflected position to a straight position.
17. The method of claim 14 wherein the deflectable beam:
has a length between two inches and five inches;
has a width between 0.15 inches and 0.35 inches; and
has a thickness less than 0.010 inches.
