What are good design gestures?: -Towards user- and machine-friendly interface-

Abstract

This paper discusses gesture design for man-machine interfaces. Traditionally, gesture-interface studies have focused on improving performance, in terms of increasing speed and accuracy, in particular reducing false positives. Many studies neglect to consider the gestures’ intrinsic machine friendliness, which can improve recognition accuracy, and user friendliness, which makes a gesture easier to use and to remember. In this paper, we investigate machine-and user-friendly gestures and analyze the results of an Internet-based questionnaire in which 351 individuals were asked to assign gestures to eight operations.
