Abstract

Augmented Reality combines real world and virtual information in interactive visualizations. Since phones started integrating GPS, compass and accelerometer, several Augmented Reality browsers for phones have hit the market. These are applications that access large amounts of geo-referenced information from online sources and present it at corresponding physical locations, superimposed onto a live video stream. However, Augmented Reality is constrained by the camera's field of view and restricted to first- person views, limiting the amount of overview that users can gain. We present two zooming interfaces that compensate for these constraints by enabling users to smoothly zoom between the Augmented Reality view and (1) an egocentric panoramic view of 360°, and (2) an exocentric top-down view. We present the results from two studies that show how in most search tasks our zooming interfaces are faster and require less panning than an overlay- based tool, scaling better as the amount of information grows.
