Mobile Media Metadata: The Future of Mobile Imaging

Seminar on People, Computers, and Design
Stanford University April 2,2004

The devices and usage context of consumer digital photography are undergoing rapid transformation from the traditional camera-to-desktop-to-network image pipeline to an integrated mobile imaging experience. In 2003, more camera phones were sold than digital cameras worldwide. The ascendancy of mobile media capture devices makes possible a significant new paradigm for digital imaging because, unlike traditional digital cameras, camera phones integrate capture, programmable processing, networking, and rich user interaction capabilities in one mobile device. We will discuss our Mobile Media Metadata prototype (MMM) which leverages the spatio-temporal context and social community of media capture to infer media content. In our approach we:

· Gather all automatically available information at the point of capture (time, spatial location, phone user, etc.)
· Use metadata similarity algorithms to find similar media that has been annotated before
· Take advantage of this previously annotated media to make educated guesses about the content of the newly captured media
· Interact in a simple and intuitive way with the phone user to confirm and augment system-supplied metadata for captured media

As a result of this approach, we believe we will solve a fundamental problem in personal media production and reuse-the need to have content-based access to the media consumers capture and share on mobile imaging devices. This talk will address our Mobile Media Metadata technology, various mobile media applications designs, user interaction issues, and future project in mobile imaging.

Marc Davis is an Assistant Professor at the School of Information Management and Systems (SIMS) at the University of California at Berkeley where he directs the Garage Cinema Research group ( His work is focused on creating the technology and applications that will enable daily media consumers to become daily media producers. Prof. Davis’ research and teaching encompass the theory, design, and development of digital media systems for creating and using media metadata to automate media production and reuse. As part of his doctoral dissertation at the MIT Media Laboratory, he developed Media Streams, an iconic visual language for annotating, retrieving, and repurposing digital video. From 1993 to 1998 at Interval Research Corporation, he led research and development teams in automatic media production technology for which a patent was awarded in 2001. From 1999 to 2002, Prof. Davis was Chairman and Chief Technology Officer of Amova, Inc., a developer of media automation and personalization technology. At UC Berkeley, Prof. Davis is a Co-Founder and Executive Committee Member of the interdisciplinary Center for New Media (CNM). He is also an Advisory Board Member of the Art, Technology, and Culture Colloquium (ATC) and an Affiliated Faculty Member of the Berkeley Institute of Design (BiD).
