HoverFlow: expanding the design space of around-device interaction

In this paper we explore the design space of around-device interaction (ADI). This approach seeks to expand the interaction possibilities of mobile and wearable devices beyond the confines of the physical device itself to include the space around it. This enables rich 3D input, comprising coarse movement-based gestures, as well as static position-based gestures. ADI can help to solve occlusion problems and scales down to very small devices. We present a novel around-device interaction interface that allows mobile devices to track coarse hand gestures performed above the device’s screen. Our prototype uses infrared proximity sensors to track hand and finger positions in the device’s proximity. We present an algorithm for detecting hand gestures and provide a rough overview of the design space of ADI-based interfaces.
