The ACM Symposium on Applied Perception (ACM SAP), formerly known as APGV, aims to further the development of inter-disciplinary research that crosses the boundaries between perception and disciplines such as graphics, visualization, vision, haptics and acoustics. These fields can benefit from the exchange of ideas and the scope includes applications and algorithms in any area of research that incorporates elements of perception and computer science. Our ninth annual event provides an intimate, immersive forum for exchanging ideas about areas of overlapping interests. By co-locating ACM SAP 2012 with the thirty-ninth annual SIGGRAPH conference (SIGGRAPH 2012) in Los Angeles, we aim to further promote communication between the core perception and the core computer graphics communities, and also bring back the symposium in its new form to the United States. The symposium will be hosted by the USC Institute for Creative Technologies. We invite submissions of original work in all areas of applied perception. Relevant areas include: Modeling, rendering, and animation Visualization Computational aesthetics Haptic rendering, haptic input and perception Computer vision Color vision and color appearance modeling Interaction techniques and interfaces Augmented reality Virtual worlds Display technologies Auditory display and interfaces Perceptual auditory coding Spatialized sound Speech synthesis and recognition Sensory integration Multimodal rendering Spatial and temporal vision Empirical perception research Attention and eye movements Statistical learning and perception of natural scenes Perception of shapes, surfaces and materials PAPERS Research can be submitted as a long paper (up to 8 pages and a 20 minute talk), a short paper (up to 4 pages + 15 min talk), or as a poster presentation (1 page abstract). Papers that are not accepted can be considered for the poster session. Authors of posters accepted by this route will of course have the option to decline the opportunity to present a poster. Please check the formatting guidelines before submitting your work on this page. Submissions do not need to be anonymous. All papers will be carefully reviewed by our International Program Committee. Papers will be evaluated as submitted, given the limited time between submission and final version. Under a recent agreement with the ACM Transactions on Applied Perception (TAP) and the ACM Publications Board, the strongest accepted papers will be offered the possibility to be published as full papers at the ACM journal TAP. These papers will undergo a second review cycle, during which the authors will need to improve the paper as indicated by the summary review (similar to conditionally accepts at SIGGRAPH). Authors of such special issue papers must agree to present the paper at ACM SAP. As has always been the case, authors of regular ACM SAP papers can still submit to TAP regular issues with appropriate additions.
