ZoneTag is a research prototype that uses context from mobile devices to help create, find, and share photos. It allows easy 2-click photo uploads with location and time metadata. Users can then tag photos from their phone using suggested tags from things around them, their friends' tags, or other people's tags. ZoneTag also includes action tags that can trigger calls to web services. Developers are challenged to create new action tags or RSS feeds to connect to photos for a chance to win a Bluetooth GPS device. ZoneTag will soon be available on popular Nokia and other platforms.
