Ruled Line Projection System for Paper Layout Assistance Ruled Line Projection System for Paper Layout Assistance

This paper reports an evaluation experiment using our prototype system which dynamically projects ruled lines on a sheet of paper to support a user in layout design. The system projects lines at proper positions depending on shape and state of the sheet detected from camera images. In the experiment, we compared two sets of lines drawn by a subject with and without ruled lines. It was ob-served that the difference between these two conditions was significantly large, suggesting the feasibility of the proposed system. 1. Prototype system for evaluation Our proposed system [1] assumes that computers and other people do not know what task a user is drawing or writing for. This is an absolutely different point from typical augmented reality (AR) system such as a remote assistance system [2] and AR modelling system [3]. Displaying ruled lines on paper has large poten-tial to support for various tasks. This section describes hardware and software configurations of the prototype system
