Dear Colleagues, [Apologies if you receive multiple copies of this message] We invite researchers and practitioners working in the field of interactive surfaces and spaces to submit workshop proposals for ISS 2020. *ISS Workshops provide a unique opportunity to discuss ideas, challenges, and new work around more specific topics in the area of interactive spaces and surfaces.* We welcome proposals from a large variety of topics and domains. Example topics include but are not limited to: Architectural concepts and emerging trends Immersive analytics and data physicalization Museum and art installation trends Interaction paradigms around large surfaces (tangibles, pen+touch, etc.) New and emerging body and space sensing technologies Overview of social protocols, presence, territoriality, and proxemics Evaluation methods for surface applications Multi-touch interaction with mobile devices Feel, taste, smell and splash user interfaces on surfaces ... and other exciting topics! All workshops will take place on *November 8, 2020* and will run for either half a day or the full day. Workshops can be open (free to anyone who registered for it) or closed (attendees need to submit position papers). Please indicate the length and type of workshop in your proposal (see below). Accepted workshop proposals will be part of the ISS conference proceedings and available in the ACM Digital Library. *Submitting a Workshop Proposal* We request a short proposal (up to 4 pages, excluding references) in the single-column ACM Master Article Submission Template as well as an additional information sheet about the particular workshop requirements (1 page). Please include the following information in your 4-page workshop proposal: Workshop title Full contact information of all workshop organizers and the main contact person Topic, nature and goals of the workshop Relevance of the workshop to the ISS community Topics and planned activities covered in the workshop and planned activities New: A description of how the organizers plan to handle the online aspects of the workshop Given the situation with COVID-19, ISS 2020 will be online. Please indicate how you aim to facilitate and support an engaging workshop in an online format. Example tools that could be used to facilitate online brainstorming include: Mural Program Committee members for the workshop (if applicable) Please include a single additional information page (in addition to the 4-page proposal) with the following information: A call-for-papers to your workshop (200 words max.) Link to the workshop website Proposed workshop length (half-day or full-day) Workshop type (open or closed) Maximum number of people Please submit the workshop proposal using the ISS Precision Conference system by July 24, 2020. *Responsibilities of Workshop Organizers* Workshop organizers are expected to organize and facilitate all proposed workshop activities. We suggest the page limit for workshop papers to be 4–6 pages excluding references using the single-column (ACM Master Article Submission Template), but it is up to the organizers to make this decision. Due to the very tight schedule, we, unfortunately, cannot include the contributions of workshop participants into the official conference proceedings and the ACM Digital Library. Workshop organizers will be asked to: Organize and manage the review of submitted workshop papers (e.g. through a reviewing system such as EasyChair) Set a workshop position paper submission deadline (on or before October 2, 2020) and an author notification date (on or before October 19). We will provide workshop organizers a special code for early bird registration that they can give to authors in the acceptance notification.
