Digital graffiti: public annotation of multimedia content

Our physical environment is increasingly filled with multimedia content on situated, community public displays. We are designing methods for people to post and acquire digital information to and from public digital displays, and to modify and annotate previously posted content to create publicly observable threads. We support in-the-moment and on-site "person-to-place-to-people-to-persons" content interaction, annotation, augmentation and publication. We draw design inspiration from field work observations of how people remove, modify and mark up paper postings. We present our initial designs in this arena, and some initial user reactions. Keywords Annotation; digital community poster boards; threaded discussion; blogging ACM Classification Keywords H5.m. Information interfaces and presentation (e.g., HCI): Miscellaneous.
