Intended outcomes

In order to resolve the controversy of subliminal perception, it would be a great opportunity to discuss with experts in the field how they have tested subliminal interaction, and to what conclusions they have come. A possible result of the workshop would be a general statement whether or not subliminal techniques can be used to deliver information to the user without adding workload, or in what specific constellation, setting, channels, etc. the approach works. In our previous workshop at AutomotiveUI 2011, we discussed why we need to use subliminal perception with a focus on the in-vehicle context and participants created brand new projects based on subliminal perception in cars. At this workshop, we would extend its application context into more broad ubiquitous computing environments as well as to intelligent, adaptive ("smart") interfaces. The expected findings and outcomes of the workshop should push research and discussions in the field of subliminal perception forward. The main goals of the workshop are

To build up a research community discussing the topic in a broader scope,
To explore methodologies for research on subliminal perception and integration into UbiComp environments,
To highlight and discuss ethics of research and application of subliminality (related to the impact of subliminal cues on human behavior),
To gain a comprehensive view of the factors involved in subliminal human-computer interaction and their association to shifts in behavior and attitudes,
To discuss why we need to use subliminal perception in ubiquitous computing environments.

Publications, Journal

Accepted workshop contributions (position papers, 4-6 pages SIGCHI archival format) will be published in the ACM digital library. Adjunct proceedings (bunch of accepted PDFs) will be circulated between workshop participants in advance. Subsidiary material will be (on author's approval) published at the workshop website http://www.pervasive.jku.at/UbiComp2012 (e.g., Powerpoint PDF slides, posters, any additional material). To stimulate discussion about the topic in a wider audience it is planned to publish extended versions of selected papers in a journal (a special issue call, e.g., for International Journal of Human-Computer studies http://www.journals.elsevier.com/international-journal-of-human-computer-studies/ or MIT Presence http://www.mitpressjournals.org/loi/pres could be a potential outlet, is in preparation). On success of the workshop, we are also planning for follow-up workshops.
