New input schemes for new devices

Abstract

Novel input devices can potentially increase the bandwidth between users and their devices.Traditional desktop computing uses windows, icons, menus, and pointers-an interface schemebuilt for the computer mouse and very effective for pointing-and-clicking. Alternative devices provide a variety of interactions including touch-free, gesture-based input and gaze-tracking to sense the location of the user's on-screen gaze location. A previous study demonstrates that such input channels are not well-suited to a point-and-click interface alone. This study evaluates new schemes designed for these devices, including multi-modal input schemes. These experimental schemes perform worse than mouse-based input for a picture sorting task, and motion-based gesture control creates more errors. Only gaze-based input without gestures did not create more workload across all workload factors when compared to traditional mouse-based input.
