Intuitive application-specific user interfaces for mobile devices

Abstract

The user interfaces on current-day mobile devices are limited owing to their small form factor. In this paper, we propose intuitive user interfaces for two applications on mobile phones with built-in cameras, namely, a car-racing game and a map navigation application. These user interfaces are based on the visual detection of the device's self-motion. We discuss three different methodologies to implement same and conduct user studies to analyze people's acceptance of the interfaces in comparison to controlling the applications with keys on the phone. Results show that our proposed interfaces are well appreciated for their intuitiveness, even though there is a learning curve. Copyright 2007 ACM.
