IDENTIFYING HAND GESTURES BASED ON MUSCLE MOVEMENT IN THE ARM

摘要

Embodiments described herein include an arm band that captures sensor data used to identify hand gestures. When worn on the arm, the arm band permits a computing device to identify different gestures made by the hand. In one embodiment, the band measures a change in position of the tendons that control the positions of the fingers on the hand which can then be correlated to a particular hand gesture. For example, the thickness of the user's arm increases in a direction perpendicular to the palm of the hand when the fingers are extended relative to the thickness of the arm when the fingers are curled into the palm of the hand. By detecting this change in thickness, the computing device can distinguish between different gestures.

主权项

1. An arm band, comprising:
a first portion; a second portion; a pivoting element coupled to respective first ends of the first and second portions, wherein the pivoting element permits respective second ends of the first and second portions opposite of the first ends to separate relative to each other; and a sensor configured to, when the arm band is worn on the arm, generate an output signal indicative of a thickness of the arm in a direction substantially perpendicular to a palm of a hand.
