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

| Venture Starline renders individuals at pure scale on a 3D show and permits pure eye contact. |
At Google I/O 2021 we introduced Venture 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 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. 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 various research throughout a wide range of methodologies, discovering converging proof that Venture 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 Venture Starline as “extra pure.” Nevertheless, when requested to elaborate, many have issue articulating this idea in a manner that totally captures their expertise. As a result of 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 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 Venture Starline. These experiments employed within-subjects designs wherein members skilled a number of circumstances (e.g., assembly in Venture Starline vs. conventional videoconferencing) in randomized order. This allowed us to regulate for between-subject variations by evaluating how the identical particular person responded to a wide range of circumstances, 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 a single research, preliminary knowledge counsel Venture Starline improves dialog dynamics by growing charges of turn-taking. We recruited pairs of members who had by no means met one another to have unstructured conversations in each Venture Starline and conventional video conferencing. We analyzed the audio from every dialog and located that Venture Starline facilitated considerably extra dynamic “forwards and backwards” conversations in comparison with conventional video conferencing. Particularly, members averaged about 2-3 extra speaker hand-offs in Venture 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”), greater 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, members had conversations with a accomplice in each Venture Starline and conventional video conferencing. We recorded these conversations to research choose nonverbal behaviors. In Venture Starline, members have been extra animated, utilizing considerably extra hand gestures (+43%), head nods (+26%), and eyebrow actions (+49%). Individuals additionally reported a considerably higher potential to understand and convey nonverbal cues in Venture Starline than in conventional video conferencing. Along with the turn-taking outcomes, these knowledge assist clarify why conversations in Venture Starline could really feel extra pure.

Decreased 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 complicated, however one risk is that video communication is cognitively taxing as a result of it turns into tougher to convey and interpret nonverbal conduct. Contemplating earlier findings that steered Venture Starline would possibly enhance nonverbal communication, we examined whether or not video assembly fatigue may also be improved (i.e., diminished) in comparison with conventional video conferencing.
Our research discovered preliminary proof that Venture Starline certainly reduces video assembly fatigue. Individuals held 30-minute mock conferences in Venture Starline and conventional video conferencing. Assembly content material was standardized throughout members utilizing an train tailored from educational literature that emulates key components of a piece assembly, resembling brainstorming and persuasion. We then measured video assembly fatigue through the Zoom Exhaustion and Fatigue (ZEF) Scale. Moreover, we measured members’ response instances on a complicated cognitive job initially utilized in cognitive psychology. We repurposed this job as a proxy for video assembly fatigue primarily based on the belief that extra fatigue would result in slower response instances. Individuals reported considerably much less video assembly fatigue on the ZEF Scale (-31%) and had quicker response instances (-12%) on the cognitive job after utilizing Venture 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 units.
In our earlier research on nonverbal conduct, we included an exploratory information-retention job. We requested members to put in writing as a lot as they might bear in mind about every dialog (one in Venture Starline, and one in conventional video conferencing). We discovered that members wrote 28% extra on this job (by character rely) after their dialog in Venture Starline. This could possibly be as a result of they paid nearer consideration when in Venture Starline, or probably that they discovered conversations in Venture Starline to be extra partaking.
To discover the idea of attentiveness additional, we carried out a research wherein members wore eye-tracking glasses. This allowed us to calculate the share of time members spent specializing in their dialog associate’s face, an essential supply of social info in human interplay. Individuals had a dialog with a accomplice in Venture Starline, conventional video conferencing, and in individual. We discovered that members spent a considerably greater proportion of time taking a look at their dialog associate’s face in Venture Starline (+14%) than they did in conventional video conferencing. Actually, visible attentiveness in Venture Starline mirrored that of the in-person situation: members spent roughly the identical proportion of time specializing in their assembly associate’s face within the Venture Starline and in-person circumstances.

Consumer worth in actual conferences
The lab-based, experimental method used within the research above permits for causal inference whereas minimizing confounding variables. Nevertheless, one limitation of those research is that they’re low in exterior validity — that’s, they passed off in a lab atmosphere, and the extent to which their outcomes prolong to the true world is unclear. Thus, we studied precise customers inside Google who used Venture 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 Venture 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 Venture Starline on ideas resembling presence, nonverbal conduct, attentiveness, and private connection. We discovered robust proof that Venture Starline delivered throughout these 4 metrics, with over 87% of members expressing that their conferences in Venture Starline have been higher than their earlier experiences with conventional video conferencing.
Conclusion
Collectively, these findings provide a compelling case for Venture Starline’s worth to customers: improved dialog dynamics, diminished video assembly fatigue, and elevated attentiveness. Individuals expressed that Venture Starline was a major enchancment over conventional video conferencing in extremely managed lab experiments, in addition to once they used Venture 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 desperate to proceed exploring the implications of Venture Starline on human interplay.
