Measure user experience in MR (i.e., AR/VR) user studies is essential. Researchers apply a wide range of measuring methods using objective (e.g., biosignals, time logging), behavioral (e.g., gaze direction, movement amplitude), and subjective (e.g., standardized questionnaires) metrics. Many of these measurement instruments were adapted from use-cases outside of MR but have not been validated for usage in MR experiments. However, researchers are faced with various challenges and design alternatives when measuring immersive experiences. These challenges become even more diverse when running out-of-the lab studies. Measurement methods of VR experience recently received much attention. For example, research has started embedding questionnaires in the VE for various applications, allowing users to stay closer to the ongoing experience while filling out the survey. However, there is a diversity in the interaction methods and practices on how the assessment procedure is conducted. This diversity in methods underlines a missing shared agreement of standardized measurement tools for VR experiences. AR research strongly orients on the research methods from VR, e.g., using the same type of subjective questionnaires. However, some crucial technical differences require careful considerations during the evaluation. This workshop at CHI 2021 provides a foundation to exchange expertise and address challenges and opportunities of research methods in MR user studies. By this, our workshop launches a discussion of research methods that should lead to standardizing assessment methods in MR user studies. The outcomes of the workshop will be aggregated into a collective special issue journal article.

Call for Participation
To measure MR experiences, researchers apply a range of research methods using objective (e.g., biosignals, logging, behavioural), and subjective (e.g., questionnaires) metrics. However, the assessment methods are heterogeneous and miss consistency among the user studies which impedes transferability of the results.
This one-day virtual CHI2021 workshop will focus on common practices of evaluation methods and their methodological, technical, and design challenges. We invite researchers and practitioners from all subfields of HCI to drive the research agenda of the research practices, technologies, and challenges of MR user studies. This workshop invites submissions of position papers (2-4 pages excluding references according to the (single column) ACM Templates), covering but not limited to the following topics:
- Measurement methods (behavioural, objective, subjective) for single- or multi-user MR
- Technical challenges/solutions/artifacts for assessment methods in and outside the lab. E.g., interaction for in-VR measurements, use of biosignals, assessing behavioral measures
- Experimenter-participant communication (e.g., telepresence, avatarization)
Submissions will be selected by the workshop organizers based on the relevance to the workshop topic and their potential to engender insightful discussions at the workshop. At the workshop, accepted papers will have a 3-4 minutes video presentation. At least one author of the accepted paper must attend the virtual workshop. All participants must register for both the workshop and for at least one day of the conference.
- Deadline: February 21st, 2021 at 12pm (noon) PT
- Format: non anonymized, 2-4 pages excluding references, using ACM Submission Template
