Photos for information: a field study of cameraphone computer vision interactions in tourism.

Advances in mobile computing and computer vision can support camera-based interactions with mobile devices, including systems that use image-matching to support getting information about objects identified by the camera. These interfaces, sometimes considered mobile augmented reality, can be applied in many domains. This paper reports on a field study of these interfaces in a tourism application, which begins to address questions about embodied interaction, existing photo-taking practices, and alternative interfaces.
