How Venture Starline improves distant communication – Google AI Weblog

As corporations settle into a brand new regular of hybrid and distributed work, distant communication know-how stays important for connecting and collaborating with colleagues. Whereas this know-how has improved, the core consumer expertise usually falls brief: dialog can really feel stilted, consideration might be troublesome to take care of, and utilization might 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 know-how mission 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 a variety of research throughout quite a lot of methodologies, discovering converging proof that Venture Starline outperforms conventional video conferencing by way of dialog dynamics, video assembly fatigue, and attentiveness. A few of these outcomes have been beforehand revealed 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.” Nonetheless, when requested to elaborate, many have problem articulating this idea in a manner that absolutely captures their expertise. As a result of human communication depends partly on unconscious processes like nonverbal habits, individuals may need a tough time reflecting on these processes which might be doubtlessly impacted by experiencing a novel know-how. To deal with this problem, we carried out a collection of behavioral lab experiments to make clear what “extra pure” may imply for Venture Starline. These experiments employed within-subjects designs during which individuals skilled a number of circumstances (e.g., assembly in Venture 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 quite a lot of circumstances, thus rising statistical energy and lowering the pattern dimension essential to detect statistical variations (pattern sizes in our behavioral experiments vary from ~ 20 to 30).

In a single examine, preliminary knowledge counsel Venture Starline improves dialog dynamics by rising charges of turn-taking. We recruited pairs of individuals 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 “backwards and forwards” conversations in comparison with conventional video conferencing. Particularly, individuals 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). Contributors 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 examine, individuals had conversations with a accomplice in each Venture Starline and conventional video conferencing. We recorded these conversations to investigate choose nonverbal behaviors. In Venture Starline, individuals have been extra animated, utilizing considerably extra hand gestures (+43%), head nods (+26%), and eyebrow actions (+49%). Contributors additionally reported a considerably higher skill 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.

We recorded individuals to quantify their nonverbal behaviors and located that they have been extra animated in Venture Starline (left) in comparison with conventional video conferencing (proper).

Decreased video assembly fatigue

A well-documented problem of video conferencing, particularly throughout 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 tougher to convey and interpret nonverbal habits. Contemplating earlier findings that urged Venture Starline may enhance nonverbal communication, we examined whether or not video assembly fatigue may additionally be improved (i.e., decreased) in comparison with conventional video conferencing.

Our examine discovered preliminary proof that Venture Starline certainly reduces video assembly fatigue. Contributors held 30-minute mock conferences in Venture Starline and conventional video conferencing. Assembly content material was standardized throughout individuals utilizing an train tailored from educational literature that emulates key parts 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 occasions on a advanced cognitive activity initially utilized in cognitive psychology. We repurposed this activity as a proxy for video assembly fatigue based mostly on the belief that extra fatigue would result in slower response occasions. Contributors reported considerably much less video assembly fatigue on the ZEF Scale (-31%) and had quicker response occasions (-12%) on the cognitive activity 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 gadgets.

In our earlier examine on nonverbal habits, we included an exploratory information-retention activity. We requested individuals to jot down as a lot as they may bear in mind about every dialog (one in Venture Starline, and one in conventional video conferencing). We discovered that individuals wrote 28% extra on this activity (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 presumably that they discovered conversations in Venture Starline to be extra partaking.

To discover the idea of attentiveness additional, we carried out a examine during which individuals wore eye-tracking glasses. This allowed us to calculate the share of time individuals spent specializing in their dialog companion’s face, an essential supply of social info in human interplay. Contributors had a dialog with a accomplice in Venture Starline, conventional video conferencing, and in particular person. We discovered that individuals spent a considerably increased proportion of time taking a look at their dialog companion’s face in Venture Starline (+14%) than they did in conventional video conferencing. In truth, visible attentiveness in Venture Starline mirrored that of the in-person situation: individuals spent roughly the identical proportion of time specializing in their assembly companion’s face within the Venture Starline and in-person circumstances.

The usage of eye-tracking glasses and facial detection software program allowed us to quantify individuals’ gaze patterns. The video above illustrates how a hypothetical participant’s eye monitoring knowledge (purple dot) correspond to their assembly companion’s face (white field).

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 lengthen to the actual 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 rapid 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 comparable to presence, nonverbal habits, attentiveness, and private connection. We discovered sturdy proof that Venture Starline delivered throughout these 4 metrics, with over 87% of individuals expressing that their conferences in Venture Starline have been higher than their earlier experiences with conventional video conferencing.


Collectively, these findings provide a compelling case for Venture Starline’s worth to customers: improved dialog dynamics, decreased video assembly fatigue, and elevated attentiveness. Contributors 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 wanting to proceed exploring the implications of Venture Starline on human interplay.
