**apologies for cross-posting** *== Workshop at CHI 2019 * *== Call for Participation - Challenges Using Head-Mounted Displays in Shared and Social Spaces* Everyday mobile usage of Head-Mounted Displays (AR and VR) is becoming a feasible consumer reality. The current research agenda for these devices has a strong focus on technological impediments (e.g. locomotion, tracking, input devices). This ignores significant challenges in the usage and perception of HMDs in shared and social spaces where HMD users are co-located with non-HMD users and are likely to be observed while interacting. We invite academics, artists, designers and practitioners to create a common understanding of upcoming challenges and derive a research agenda for this new topic. In this CHI 2019 workshop, we will focus on group work in which we will experience and discuss challenges of HMDs in shared and social spaces. **** Important Dates **** *Submission Deadline: February 1st, 2019* *Notification: February 28th, 2019* *Workshop Date: May 05th, 2019 (08:00 - 14:00)* We invite submissions of position papers: 4 pages in SIGCHI Extended Abstract format (references excluded) of work within the scope of challenges and opportunities for HMDs in shared and social spaces (via EasyChair: https://easychair.org/conferences/?conf=shmd19). Each participant will have 5 minutes for a oral presentation of his/her work. *Relevant topics include, but are not limited to:* **Social Acceptability of HMD Usage* **Tackling Isolation and Exclusion* **Shared Experiences in Shared Spaces* **Ethical Implications of Public Mixed Reality* Participants will be selected according to the suitability of their research to contribute to the workshop outcome or the relevance of their workshop position paper. Please note that at least one author of each accepted position paper must attend the workshop. All workshop participants must register for both the workshop and for at least one day of the conference.
