We invite researchers, practitioners, and designers to participate in the 1st Joint Workshop on Cross Reality (CR). Cross Reality is an emerging technology that focuses on the concurrent usage of or the transition between multiple systems at different points on the reality-virtuality continuum, including Virtual Reality, Augmented Virtuality, and Augmented Reality. CR has gained significant attention in recent years due to its potential for revolutionizing various research and industry areas where users need to comprehend and explore spatial data and its relevant information in different forms. Five separate workshops on individual Cross Reality topics have been held in the past three years. This workshop will bring together the community of CR researchers and aims to establish the research area further. The goal of the workshop is to explore the current challenges, solutions, and opportunities in the field of CR. WORKSHOP CONTRIBUTIONS We welcome position paper submissions from 2-4 pages long, excluding references. All paper submissions must be in English. Paper quality versus length will be assessed according to a contribution-per-page judgment. All submissions will be accepted or rejected as workshop papers. All accepted papers will be archived in the IEEE Xplore digital library. Topics of interest include, but are not limited to: - Cross-reality environment design: virtuality and reality - Visual representations in cross-reality systems - Cross-reality transitions across multiple interfaces - Cross-reality interaction - Multimodal interaction, perception, and cognition - Real-world tool use and tangibles as input to CR systems - Input and output devices - Collaborative cross-reality immersive analytics - Collaboration across the reality-virtuality continuum - Cross-reality user experience - Cross-reality user behavior - Cross-reality tools, frameworks, and APIs - Testing Cross-reality systems - Design guidelines for Cross-reality applications - Evaluation of Cross-reality experiences and systems - Cross-reality applications and scenarios - Cross-reality use cases in, e.g., education, industry, transportation, sports, healthcare IMPORTANT DATES - Submissions deadline: July 17th - Acceptance notifications: August 7th - Camera-ready versions: August 21st - Workshop day: October 16th WORKSHOP DETAILS The workshop will be held in conjunction with ISMAR 2023. We plan to offer our workshop in a hybrid format, meaning we will offer both online and in-person participation for our attendees.
