Task supporting system using head mounted display and augmented reality (AR) is described. Since measurements of deformation and temperature of a work piece is needed for line heating task, an interactive scheme that includes measurement instruments combined to the AR system is proposed. Whole system is designed so that the coordinates of the measurement instruments are transformed to the marker based one. It is performed by detecting markers using ARToolKit and a video camera attached to the instruments. Errors in position and pose of a marker detected by ARToolKit are experimentally investigated to estimate the practical merit of the design. Systematic errors caused by misread of a marker edge are analyzed. It is revealed that the position accuracy in the optical axis direction of the video camera is not accurate enough for the supporting system when single marker is only detected.
