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

At Google I/O 2021 we introduced Project Starline, a know-how challenge that mixes advances in {hardware} and software program to create a distant communication expertise that feels such as you’re collectively, even if you’re 1000’s 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. But to what extent do these technological improvements translate to significant, observable enchancment in person worth in comparison with conventional video conferencing?
In this weblog we share outcomes from various research throughout a wide range of methodologies, discovering converging proof that Project Starline outperforms conventional video conferencing when it comes to dialog dynamics, video assembly fatigue, and attentiveness. Some of those outcomes had been previously 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 Project Starline as “more natural.” However, when requested to elaborate, many have problem articulating this idea in a method that absolutely captures their expertise. Because human communication depends partly on unconscious processes like nonverbal conduct, individuals may need a tough time reflecting on these processes which can be probably impacted by experiencing a novel know-how. To handle this problem, we carried out a sequence of behavioral lab experiments to make clear what “more natural” may imply for Project Starline. These experiments employed within-subjects designs through which contributors skilled a number of situations (e.g., assembly in Project 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 decreasing the pattern measurement essential to detect statistical variations (pattern sizes in our behavioral experiments vary from ~ 20 to 30).
In one examine, preliminary knowledge recommend Project Starline improves dialog dynamics by growing charges of turn-taking. We recruited pairs of contributors who had by no means met one another to have unstructured conversations in each Project Starline and conventional video conferencing. We analyzed the audio from every dialog and located that Project Starline facilitated considerably extra dynamic “backwards and forwards” conversations in comparison with conventional video conferencing. Specifically, contributors averaged about 2-3 extra speaker hand-offs in Project 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). Participants additionally rated their Starline conversations as considerably extra pure (“smooth,” “easy,” “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 examine, contributors had conversations with a confederate in each Project Starline and conventional video conferencing. We recorded these conversations to research choose nonverbal behaviors. In Project Starline, contributors had been extra animated, utilizing considerably extra hand gestures (+43%), head nods (+26%), and eyebrow actions (+49%). Participants additionally reported a considerably higher capacity to understand and convey nonverbal cues in Project Starline than in conventional video conferencing. Together with the turn-taking outcomes, these knowledge assist clarify why conversations in Project Starline might really feel extra pure.

Reduced 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 risk is that video communication is cognitively taxing as a result of it turns into harder to convey and interpret nonverbal conduct. Considering earlier findings that steered Project Starline may 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 examine discovered preliminary proof that Project Starline certainly reduces video assembly fatigue. Participants held 30-minute mock conferences in Project Starline and conventional video conferencing. Meeting content material was standardized throughout contributors utilizing an train tailored from tutorial literature that emulates key parts of a piece assembly, corresponding to brainstorming and persuasion. We then measured video assembly fatigue by way of the Zoom Exhaustion and Fatigue (ZEF) Scale. Additionally, we measured contributors’ response instances on a advanced cognitive job initially utilized in cognitive psychology. We repurposed this job as a proxy for video assembly fatigue based mostly on the idea that extra fatigue would result in slower response instances. Participants reported considerably much less video assembly fatigue on the ZEF Scale (-31%) and had quicker response instances (-12%) on the cognitive job after utilizing Project Starline in comparison with conventional video conferencing.
Increased attentiveness
 |
Another problem with video conferencing is focusing consideration on the assembly at hand, moderately than on different browser home windows or secondary units.
In our earlier examine on nonverbal conduct, we included an exploratory information-retention job. We requested contributors to jot down as a lot as they may keep in mind about every dialog (one in Project Starline, and one in conventional video conferencing). We discovered that contributors wrote 28% extra on this job (by character depend) after their dialog in Project Starline. This may very well be as a result of they paid nearer consideration when in Project Starline, or probably that they discovered conversations in Project Starline to be extra partaking.
To discover the idea of attentiveness additional, we carried out a examine through which contributors wore eye-tracking glasses. This allowed us to calculate the share of time contributors spent specializing in their dialog associate’s face, an necessary supply of social data in human interplay. Participants had a dialog with a accomplice in Project Starline, conventional video conferencing, and in particular person. We discovered that contributors spent a considerably increased proportion of time taking a look at their dialog associate’s face in Project Starline (+14%) than they did in conventional video conferencing. In reality, visible attentiveness in Project Starline mirrored that of the in-person situation: contributors spent roughly the identical proportion of time specializing in their assembly associate’s face within the Project Starline and in-person situations.

User worth in actual conferences
The lab-based, experimental strategy used within the research above permits for causal inference whereas minimizing confounding variables. However, one limitation of those research is that they’re low in exterior validity — that’s, they passed off in a lab setting, and the extent to which their outcomes lengthen to the actual world is unclear. Thus, we studied precise customers inside Google who used Project 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 Project Starline. We used post-meeting surveys to seize instant 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 Project Starline on ideas corresponding to presence, nonverbal conduct, attentiveness, and private connection. We discovered sturdy proof that Project Starline delivered throughout these 4 metrics, with over 87% of contributors expressing that their conferences in Project Starline had been higher than their earlier experiences with conventional video conferencing.
Conclusion
Together, these findings supply a compelling case for Project Starline’s worth to customers: improved dialog dynamics, decreased video assembly fatigue, and elevated attentiveness. Participants expressed that Project Starline was a big enchancment over conventional video conferencing in extremely managed lab experiments, in addition to after they used Project 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 wanting to proceed exploring the implications of Project Starline on human interplay.
