Abstract
Objective:
The purpose of this study was to develop a lexicon for 3-D hand gestures for common human–computer interaction (HCI) tasks by considering usability and effort ratings.
Background:
Recent technologies create an opportunity for developing a free-form 3-D hand gesture lexicon for HCI.
Method:
Subjects (
Results:
A final task gesture set is proposed based primarily on subjective ratings and hand posture risk. The different dimensions used for evaluating task gestures were not highly correlated and, therefore, measured different properties of the task–gesture match.
Application:
A method is proposed for generating a user-developed 3-D gesture lexicon for common HCIs that involves subjective ratings and a posture risk rating for minimizing arm and hand fatigue.
