ABSTRACT
We contribute the idea of an instrumented office chair as a platform for spatial augmented reality (SAR). Seated activities are tracked through chair position, back tilt, rotation, surface sensors, and touches along the armrest. A depth camera tracks chair position using simultaneous localization and mapping and a servo-actuated pan-tilt projector mounted on the side of the chair displays content for applications. Eleven demonstration scenarios explore usage possibilities and an online survey gathers feedback. Many respondents perceive the concept as useful and comfortable, validating it as a promising direction for personal portable SAR.
