96‐4: Invited Paper:Surface Dial: Enabling Tangible Dual‐handed Interactions on Capacitive Touchscreens

Surface Dial is a mass production PC accessory implementing a tangible interface for on‐and off‐screen interactions. It enables a dual‐handed interaction model in content creation tasks like drawing, video editing, presentation and data visualization. We delve into design considerations, including development of a capacitive approach for on‐screen detection and tracking.
