Abstract
A typical office worker nowadays spends the majority of his time sedentary in the course of his working life. In this paper, we address the problem of sedentariness in the context of office work through smooth integration of light physical activity into the daily work routine. Equipping a flexible office chair with motion sensing functionality, the chair becomes a ubiquitous input device that provides an office worker with the possibility to use the movements of his body for tilting, rotating, or bouncing to control his workplace computer. Based on this idea, we apply an existing gesture taxonomy to body movements on an active office chair, and explore different application scenarios for ubiquitous gestural chair interaction.
