Understanding where to project information on the desk for supporting work with paper and pen

Abstract

Paper-based work still remains in daily life, and digital information may help such paper-based work. In this paper, we assume an environment, in which a projector presents information on the desk that is used in a transcription task such as filling a form of notification of change of address to post office. We explore the effect of the distance and the direction between the transcription target (printed) and the reference information (projected) on the efficiency and effectiveness. We confirmed that presentation on the upper sides of the transcription target and the area close to the target showed better results (faster task completion and lower error rate), while worse results were observed on the lower right side that was around the dominant hands.
