In Proceedings of the European Conference on Ambient Intelligence (AmI 2008), Nürnberg, Germany, November 19 - 22, 2008, ISBN 978-3-540-89616-6

The advancement of Ubicomp technologies leverages mobile interaction with physical objects and facilitates ubiquitous access to information and services. This provides new opportunities for mobile interaction with the real world, but also creates new challenges regarding the complexity of mobile applications, their interaction design and usability. In order to take advantage of this potential beyond simple interaction with single objects and tags, this paper investigates mobile interaction with multiple objects, tags and associated information. It introduces Collect&Drop as a generic technique for Multi-Tag Interaction that supports the collection, storage and management of information from the real world as well as its usage with different services. This paper describes the concept, architecture and interaction design of Collect&Drop and presents a user study that evaluates its features.
