A Gesture Controlled User Interface for Inclusive Design and Evaluative Study of Its Usability

Abstract

To meet the challenges of ubiquitous computing, ambient technologies and an increasingly older population, research- ers have been trying to break away from traditional modes of interaction. A history of studies over the past 30 years reported in this paper suggests that Gesture Controlled User Interfaces (GCUI) now provide realistic and affordable opportunities, which may be appropriate for older and disabled people. We have developed a GCUI prototype applica- tion, called Open Gesture, to help users carry out everyday activities such as making phone calls, controlling their tele- vision and performing mathematical calculations. Open Gesture uses simple hand gestures to perform a diverse range of tasks via a television interface. This paper describes Open Gesture and reports its usability evaluation. We conclude that this inclusive technology offers some potential to improve the independence and quality of life of older and dis- abled users along with general users, although there remain significant challenges to be overcome.
