It is our great pleasure to present the proceedings of the international ACM Symposium on Applied Perception (SAP), held on August 11-12, 2018 in Vancouver, BC, Canada. As is customary for SAP, conferences held in even years are co-located with SIGGRAPH. The conference chairs are Cindy Grimm and Peter Willemsen, program chairs are Joseph Kearney and Bernhard Riecke.

SAP, formerly known as APGV, aims to broadly support and promote interdisciplinary research at the intersection of perception and computer science, focusing on disciplines such as computer graphics, virtual reality, vision science, haptics and acoustics. Our fifteenth annual event features exciting new research touching all of these disciplines.

This year's program includes 24 papers selected from 53 total submissions via rigorous double-blind peer review by our 60-member International Program Committee. Four of these 24 papers were selected to appear in a special issue of the ACM Transactions on Applied Perception; the other 20 papers are published here in these proceedings. Our conference program this year includes 15 posters presented in a dedicated session, organized by Posters Chair Betsy Sanders.

We are looking forward to welcoming Sarah H. Creem-Regehr & William B. Thompson as our keynote speakers to discuss their experience as longtime collaborations in their talk titled: “Working Together: Do's, don'ts, and success stories of multidisciplinary research”.

We are deeply grateful to Stephen Spencer, chair of the ACM SIGGRAPH Publications Committee, whose diligence and effort brought these proceedings successfully together as a coherent whole. We thank the ACM publications board for supporting the idea of fast-tracking select publications directly into TAP, and the TAP editorial staff for working closely with us to ensure that the papers were available in the Digital Library by the time of the symposium.

Finally, the proceedings represent a snapshot of a fast-moving interdisciplinary field at one moment in time. We wholeheartedly thank those members of the field who invested time and energy in the symposium by submitting their work, or by reviewing the submitted work. We saw the work over the course of the submission and review process, and are proud of its quality and the resulting volume.
