Abstract

In 2020, we have witnessed global experimentation of remote co-working, co-learning, and co-habiting, leading to the re-emergence of a collective search for platforms and paradigms that can optimally coalesce the virtual and physical settings - what has been studied as "hybrid models". In this context, we examine the opportunities that the advances in Spatial Audio techniques can create to improve hybrid meetings. Concretely, we present a controlled study in which 84 participants used an online platform to follow six pre-recorded semi-scripted dialogues. The videos were around two minutes long and each of them simulated a piece of conversation in the physical meeting room among three actors who played the role of co-located attendees. The six videos represented six conditions: three auditive formats, (x2) once co-located attendees wore face masks, and once without masks. We compared the experiences of the participants (remote attendees) in these six conditions. Analyzing three types of data, namely, comprehension/memory test results, self-reported ratings, and eye-tracking, we have found reinforcing evidence that demonstrates the benefits of binaural audio in hybrid settings.
