“ ... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested. ”

-- Steve Krug, Don't Make Me Think, p. 136

Quam, David L., Williams, George B., Agnew, Jeffery R. and Browne, Patricia C. (1989): An Experimental Determination of Human Hand Accuracy with a DataGlove. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 315-319.

“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 6{deg} for the four fingers and 11{deg} for the thumb, repeatability was 3{deg} for the four fingers and 9{deg} for the thumb, and linearity varied from 2 to 5{deg}. Although the mean location accuracy was 1 inch and the mean orientation accuracy was 17{deg}, 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 9{deg}. However, the within-subject location repeatability was 0.13 inches, while the orientation repeatability was 2{deg}.”
