“AR-Based Supporting System by Overlay Display of Instruction Video”

Augmented Reality (AR) based work supporting system can help users intuitively. For developing AR systems, it is necessary to create contents to be overlaid. In most cases, such contents are newly-created with CG according to the application. In our system, we utilize already-existing videos as instruction videos which are transformed to the user's view point and overlaid onto the user' s view. In order to solve the problem that the instruction video and the user's view may be visually confused, we add various visual effects to the instruction video such as transparency, enhancement of contours, and so on. By dividing the instruction video into some sections according to the work, moreover, the user interactively goes to the next step in the instruction video after the user's operation has finished. Therefore the user can carry on the work at his/her own pace. In the usability test, the users evaluated how to provide the instruction video in our system through two types of work; making origami and building block. As a result, we can find that user's visibility improves by transforming the instruction video to the user's view. As for evaluation of visual effects, we can classify those effects according to the work and obtain the guideline in applying the other work to our system.
