As corporations settle into a brand new regular of hybrid and distributed work, distant communication expertise stays important for connecting and collaborating with colleagues. Whereas this expertise has improved, the core consumer expertise usually falls brief: dialog can really feel stilted, consideration may be troublesome to take care of, and utilization may be fatiguing.

At Google I/O 2021 we introduced Mission Starline, a expertise challenge that mixes advances in {hardware} and software program to create a distant communication expertise that feels such as you’re collectively, even once you’re hundreds of miles aside. This notion of co-presence is created by representing customers in 3D at pure scale, enabling eye contact, and offering spatially correct audio. However to what extent do these technological improvements translate to significant, observable enchancment in consumer worth in comparison with conventional video conferencing?
On this weblog we share outcomes from numerous research throughout a wide range of methodologies, discovering converging proof that Mission Starline outperforms conventional video conferencing when it comes to dialog dynamics, video assembly fatigue, and attentiveness. A few of these outcomes have been beforehand printed whereas others we’re sharing for the primary time as preliminary findings.
Improved dialog dynamics
 |
In our qualitative research, customers usually describe conversations in Mission Starline as “extra pure.” Nonetheless, when requested to elaborate, many have problem articulating this idea in a approach that totally captures their expertise. As a result of human communication depends partly on unconscious processes like nonverbal habits, folks might need a tough time reflecting on these processes which can be probably impacted by experiencing a novel expertise. To deal with this problem, we carried out a collection of behavioral lab experiments to make clear what “extra pure” would possibly imply for Mission Starline. These experiments employed within-subjects designs by which individuals skilled a number of situations (e.g., assembly in Mission Starline vs. conventional videoconferencing) in randomized order. This allowed us to manage for between-subject variations by evaluating how the identical particular person responded to a wide range of situations, thus growing statistical energy and lowering the pattern measurement essential to detect statistical variations (pattern sizes in our behavioral experiments vary from ~ 20 to 30).
In a single research, preliminary knowledge recommend Mission Starline improves dialog dynamics by growing charges of turn-taking. We recruited pairs of individuals who had by no means met one another to have unstructured conversations in each Mission Starline and conventional video conferencing. We analyzed the audio from every dialog and located that Mission Starline facilitated considerably extra dynamic “forwards and backwards” conversations in comparison with conventional video conferencing. Particularly, individuals averaged about 2-3 extra speaker hand-offs in Mission Starline conversations in comparison with these in conventional video conferencing throughout a two minute subsample of their dialog (a uniform choice on the finish of every dialog to assist standardize for interpersonal rapport). Individuals additionally rated their Starline conversations as considerably extra pure (“easy,” “simple,” “not awkward”), increased in high quality, and simpler to acknowledge when it was their flip to talk in comparison with conversations utilizing conventional video conferencing.
In one other research, individuals had conversations with a accomplice in each Mission Starline and conventional video conferencing. We recorded these conversations to investigate choose nonverbal behaviors. In Mission Starline, individuals have been extra animated, utilizing considerably extra hand gestures (+43%), head nods (+26%), and eyebrow actions (+49%). Individuals additionally reported a considerably higher capacity to understand and convey nonverbal cues in Mission Starline than in conventional video conferencing. Along with the turn-taking outcomes, these knowledge assist clarify why conversations in Mission Starline might really feel extra pure.

Lowered video assembly fatigue
 |
A well-documented problem of video conferencing, particularly inside the office, is video assembly fatigue. The causes of video assembly fatigue are advanced, however one chance is that video communication is cognitively taxing as a result of it turns into harder to convey and interpret nonverbal habits. Contemplating earlier findings that instructed Mission Starline would possibly enhance nonverbal communication, we examined whether or not video assembly fatigue may also be improved (i.e., decreased) in comparison with conventional video conferencing.
Our research discovered preliminary proof that Mission Starline certainly reduces video assembly fatigue. Individuals held 30-minute mock conferences in Mission Starline and conventional video conferencing. Assembly content material was standardized throughout individuals utilizing an train tailored from tutorial literature that emulates key components of a piece assembly, comparable to brainstorming and persuasion. We then measured video assembly fatigue by way of the Zoom Exhaustion and Fatigue (ZEF) Scale. Moreover, we measured individuals’ response instances on a advanced cognitive job initially utilized in cognitive psychology. We repurposed this job as a proxy for video assembly fatigue primarily based on the idea that extra fatigue would result in slower response instances. Individuals reported considerably much less video assembly fatigue on the ZEF Scale (-31%) and had sooner response instances (-12%) on the cognitive job after utilizing Mission Starline in comparison with conventional video conferencing.
Elevated attentiveness

One other problem with video conferencing is focusing consideration on the assembly at hand, slightly than on different browser home windows or secondary gadgets.
In our earlier research on nonverbal habits, we included an exploratory information-retention job. We requested individuals to jot down as a lot as they may keep in mind about every dialog (one in Mission Starline, and one in conventional video conferencing). We discovered that individuals wrote 28% extra on this job (by character depend) after their dialog in Mission Starline. This could possibly be as a result of they paid nearer consideration when in Mission Starline, or probably that they discovered conversations in Mission Starline to be extra participating.
To discover the idea of attentiveness additional, we carried out a research by which individuals wore eye-tracking glasses. This allowed us to calculate the share of time individuals spent specializing in their dialog associate’s face, an necessary supply of social info in human interplay. Individuals had a dialog with a accomplice in Mission Starline, conventional video conferencing, and in individual. We discovered that individuals spent a considerably increased proportion of time taking a look at their dialog associate’s face in Mission Starline (+14%) than they did in conventional video conferencing. Actually, visible attentiveness in Mission Starline mirrored that of the in-person situation: individuals spent roughly the identical proportion of time specializing in their assembly associate’s face within the Mission Starline and in-person situations.

Person worth in actual conferences
The lab-based, experimental strategy used within the research above permits for causal inference whereas minimizing confounding variables. Nonetheless, one limitation of those research is that they’re low in exterior validity — that’s, they occurred in a lab surroundings, and the extent to which their outcomes prolong to the true world is unclear. Thus, we studied precise customers inside Google who used Mission Starline for his or her day-to-day work conferences and picked up their suggestions.
An inside pilot revealed that customers derive significant worth from utilizing Mission Starline. We used post-meeting surveys to seize quick suggestions on particular person conferences, longer month-to-month surveys to seize holistic suggestions on the expertise, and carried out in-depth qualitative interviews with a subset of customers. We evaluated Mission Starline on ideas comparable to presence, nonverbal habits, attentiveness, and private connection. We discovered robust proof that Mission Starline delivered throughout these 4 metrics, with over 87% of individuals expressing that their conferences in Mission Starline have been higher than their earlier experiences with conventional video conferencing.
Conclusion
Collectively, these findings provide a compelling case for Mission Starline’s worth to customers: improved dialog dynamics, decreased video assembly fatigue, and elevated attentiveness. Individuals expressed that Mission Starline was a big enchancment over conventional video conferencing in extremely managed lab experiments, in addition to once they used Mission Starline for his or her precise work conferences. We’re excited to see these findings converge throughout a number of methodologies (surveys, qualitative interviews, experiments) and measurements (self-report, behavioral, qualitative), and we’re desirous to proceed exploring the implications of Mission Starline on human interplay.
