An Experimental Determination of Human Hand Accuracy with a DataGlove

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 60 for the four fingers and 110 for the thumb, repeatability was 30 for the four fingers and 90 for the thumb, and linearity varied from 2 to 5 O . Although the mean location accuracy was 1 inch and the mean orientation accuracy was 170, 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 90 . However, the within-subject location repeatability was 0.13 inches, while the orientation repeatability was 20 .

Evaluation of an instrumented glove for hand-movement acquisition

“…In addition, at this stage of our work, our target was to investigate the overall repeatability performance of the system. Moreover, it must be pointed out that only a few descriptions of testing protocols and experiments that evaluated glove device's characteristics are available in literature [8][9][10][11][12]. The significant parameters chosen for Humanglove repeatability testing on four male subjects showed an overall error of 6.17° (average across the four tests and the four male subjects).…”

“…Rated at 1°, but 5-10° is typical. (Quam, Williams, Agnew, & Browne, 1989;Wiseet. al., 1990) Better than 1° (Sturman i Zeltzer, 1994) Better than 1° (Sturman/ Zeltzer, 1994) Feedback requirements for applications that involve simulated object manipulation, vehicle control, and robot operations are still the subject of much research and development.…”
