In image-based approaches, a 3D object is usually represented by an Object-Centered Image Set (OCIS), which is a set of images taken from different viewpoints centered on the 3D object. Our objective is to browse such an image-based object by controlling it with a 2D mouse. Traditionally, the movement of the 2D mouse is converted to the 3D rotation angles of Pitch and Yaw only (i.e., not considering the Roll angle); most of the images in the OCIS are acquired with the camera's up-vector pointing to the North Pole of the object. In this paper, we propose a new method for browsing an image-based object relying on the augmented "yawpitch -roll" strategy. With this strategy, the system first converts the 2D mouse movement to three rotation angles: Pitch, Roll, and Yaw, and then rotates the corresponding image in the OCIS in an appropriate way before displaying it. To evaluate the performance of this strategy, we have conducted a series of experiments to compare the efficiency and precision of this strategy with two other popular strategies. The experimental result shows that the proposed strategy is easier to use for browsing image-based objects and can lead to more efficient and precise results.
