A registration method for outdoor wearable AR systems is described. Our approach is based on using a high precision gyroscope, which can measure 3DOF angle of head direction accurately, but with some drift error. We solved the drift problem with a vision-based drift compensation algorithm, which tracks natural features in the outdoor environment as landmarks from images captured by a camera on an HMD. The paper first describes the detail of the vision-based drift compensation method. Then, a calibration method for the orientation sensor is proposed. Finally, using results from an actual wearable AR system, a comparison of registration error with and without vision-based drift compensation demonstrates the feasibility of the proposed method.

We introduce AR-Jig, a new handheld tangible user interface for 3D digital modeling in augmented reality (AR) space. AR-Jig has a pin array that displays a 2D physical curve coincident with a contour of a digitally displayed 3D form. It supports physical interaction with a portion of a 3D digital representation, allowing 3D forms to be directly touched and modified. Traditional tangible user interfaces physically embody all the data; in contrast, this project leaves the majority of the data in the digital domain but gives physicality to any portion of the larger digital dataset via a handheld tool. This tangible intersection enables the flexible manipulation of digital artifacts, both physically and virtually. Through an informal test by end-users and interviews with professionals, we confirmed the potential of the AR-Jig concept while identifying the improvements necessary to make AR-Jig a practical tool for 3D digital design.
