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 maybe tiring and even infeasible when viewpoints are out of reach. In this paper, we present object-centric explorationtechniques for handheld AR that allow users to access information freely using a virtual copy metaphor to explorelarge real world objects. We evaluated our interfaces in controlled conditions and collected first experiences in areal world pilot study. Based on our findings, we put forward design recommendations that should be consideredby future generations of location-based AR browsers, 3D tourist guides, or in situated urban plannin
