In recent years, <i>tagging systems</i> have become increasingly popular. These systems enable users to add keywords (i.e., "tags") to Internet resources (e.g., web pages, images, videos) without relying on a controlled vocabulary. Tagging systems have the potential to improve search, spam detection, reputation systems, and personal organization while(More)
We describe a framework for automatically selecting a summary set of photos from a large collection of geo-referenced photographs. Such large collections are inherently difficult to browse, and become excessively so as they grow in size, making summaries an important tool in rendering these collections accessible. Our summary algorithm is based on spa-tial(More)
Developments in networked digital imaging promise to substantially affect the near-universal experience of personal photography. Designing technology for image capture and sharing requires an understanding of how people use photos as well as how they adapt emerging technology to their photographic practices, and vice versa. In this paper, we report on an(More)
This thesis presents a new computer interface metaphor for the real-time and simultaneous performance of dynamic imagery and sound. This metaphor is based on the idea of an inexhaustible, infinitely variable, time-based, audiovisual " substance " which can be gesturally created, deposited, manipulated and deleted in a free-form, non-diagrammatic image(More)
To predict the uses of new technology, we present an approach grounded in science and technology studies (STS) that examines the social uses of current technology. As part of ongoing research on next-generation mobile imaging applications, we conducted an empirical study of the social uses of personal photography. We identify three: memory, creating and(More)
The amount of personal digital media is increasing, and managing it has become a pressing problem. Effective management of media content is not possible without content-related metadata. In this paper we describe a content metadata creation process for images taken with a mobile phone. The design goals were to automate the creation of image content metadata(More)
Current computing systems are just beginning to enable the computational manipulation of temporal media like video and audio. Because of the opacity of these media they must be represented in order to be manipulable according to their contents. Knowledge representation techniques have been implicitly designed for representing the physical world and its(More)
The panel will explore the relevance of the emerging tagging systems (Flickr, Del.icio.us, RawSugar and more). Why do they seem to work? What kinds of incentives are required for users to participate? Will tagging survive and scale to mass adoption? What are the behavioral, economic, and social models that underlie each tagging system? What are the dynamics(More)
