1. A wearable device for measuring finger motion comprising:
- a bi-loop arcuate member further comprises;
a distal loop configured to encircle an intermediate phalanx of a finger;
a proximal loop configured to encircle a proximal phalanx of the finger; and
a joint-spanning strip configured to span a proximal interphalangeal joint of the finger,wherein the joint-spanning strip spans from the distal loop to the proximal loop, and wherein the joint-spanning strip bends when the proximal interphalangeal joint bends;
wherein the joint-spanning strip is configured to span a dorsal surface of the proximal interphalangeal joint, wherein the distal and proximal loops are less elastic and/or stretchable than the joint-spanning strip, and wherein the distal and proximal loops are configured to encircle the intermediate phalanx and the proximal phalanx of the finger around the longitudinal middle of the phalanges of the finger; and
a bend sensor attached to the joint-spanning strip, wherein the bend sensor is configured to span the proximal interphalangeal joint of the finger,wherein the bend sensor is an electromagnetic energy band sensor, wherein the bend sensor configured to detect bending as the finger moves, and wherein the detected bending changes flow of electromagnetic energy, and wherein the changes of the flow of the electromagnetic energy are used to measure the motion and configuration of the proximal interphalangeal joint of the finger.

Abstract
This invention can be embodied in a wearable device or system for measuring finger motion and recognizing hand gestures comprising a distal loop which encircles the intermediate phalanx of a finger, a proximal loop which encircles the proximal phalanx of the finger, a joint-spanning strip which connects these two loops, and a bend sensor which is part of the joint-spanning strip. Changes in energy transmitted through, or generated by, the bend sensor are used to measure the motion and/or configuration of the proximal interphalangeal joint.
