Both device demonstrations and design discussions are welcome for 10-minute oral presentations or demonstrations followed by 5-minute question and answers sessions. The workshop will encourage lively debate on the social, aesthetic, and ethical implications. We expect between 10 and 20 presentations or demonstrations from participants. Position papers describing submissions may range between 2 to 4 pages. The format of the submission will be PDF in ACM SIGCHI format (LaTeX and Word templates are available). Preceding the workshop, position papers will be posted and available for public comment on the workshop website. The workshop submissions will also be prepared for inclusion in the digital handout for UbiComp attendees. Submissions describing work-in-progress and early designs and systems are welcome. More details may be found in the dap 2008 call for papers.
