Nerd of the Rings -- Devices for Measuring Finger Motion and Recognizing Hand Gestures

摘要

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.

主权项

1. A wearable device for measuring finger motion comprising:
a bi-loop arcuate member which further comprises: a distal loop which is configured to encircle the intermediate phalanx of a finger; a proximal loop which is configured to encircle the proximal phalanx of the finger; and a joint-spanning strip which is configured to span the 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; and a bend sensor which is part of, or attached to, the joint-spanning strip, wherein the bend sensor is configured to span at least a portion of the proximal interphalangeal joint, and wherein 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.
