Abstract
A three-part experiment was conducted to determine the accuracy, repeatability and linearity of a human hand manipulating the DataGlove. Accuracy and repeatability of finger flexure were investigated with repeated measurements of three calibration positions. Linearity of finger flexure was investigated with steady finger and thumb curling motions. Accuracy and repeatability of hand location and orientation were investigated with repeated measurements of six hand positions. Finger flexure mean accuracy was 6º for the four fingers and 11º for the thumb, repeatability was 3º for the four fingers and 9º for the thumb, and linearity varied from 2 to 5º. Although the mean location accuracy was 1 inch and the mean orientation accuracy was 17º, the position and orientation receiver was observed to twist on the glove back. Across all subjects, the location repeatability was 0.5 inch, while the orientation repeatability was 9º. However, the within-subject location repeatability was 0.13 inches, while the orientation repeatability was 2º.
