Augmented reality (AR) enables users to retrieve additional information about the real world objects and locations. Exploring such location-based information in AR requires physical movement to different viewpoints, which may be tiring and even infeasible when viewpoints are out of reach. In this paper, we present object-centric exploration techniques for handheld AR that allow users to access information freely using a virtual copy metaphor to explore large real world objects. We evaluated our interfaces in controlled conditions and collected first experiences in a real world pilot study. Based on our findings, we put forward design recommendations that should be considered by future generations of location-based AR browsers, 3D tourist guides, or in situated urban planning.
