  Extended Reality (XR) technology - such as virtual and augmented reality - is
now widely used in Human Computer Interaction (HCI), social science and
psychology experimentation. However, these experiments are predominantly
deployed in-lab with a co-present researcher. Remote experiments, without
co-present researchers, have not flourished, despite the success of remote
approaches for non-XR investigations. This paper summarises findings from a
30-item survey of 46 XR researchers to understand perceived limitations and
benefits of remote XR experimentation. Our thematic analysis identifies
concerns common with non-XR remote research, such as participant recruitment,
as well as XR-specific issues, including safety and hardware variability. We
identify potential positive affordances of XR technology, including leveraging
data collection functionalities builtin to HMDs (e.g. hand, gaze tracking) and
the portability and reproducibility of an experimental setting. We suggest that
XR technology could be conceptualised as an interactive technology and a
capable data-collection device suited for remote experimentation.
