YouTube’s heatmaps show where eyes linger in VR videos


YouTube will dole out a heatmap for any 360-degree video with over 1,000 views. The platform has a few early observations from its nascent catalogue of VR movies. For one, despite the freedom to look anywhere, viewers spend 75 percent of their time watching the front 90 degrees, so keep the action straight ahead. But 20 percent of views focus directly behind, so don’t abandon the format’s freeform possibilities. Lastly, VR platforms are not made equal: Mobile headset users, like those donning Google’s own Cardboard, take a few seconds to get situated in a vehicle (whereas viewers with desktop systems do not).

Knowing where folks choose to look isn’t just useful for content creators. Facebook has developed a few strategies to keep streaming video bitrates low and quality high, one of which includes using AI predictive modeling to intuit the most interesting parts of a video (where viewers will focus their attention) and render that in higher resolution than other parts.

On top of the heatmap announcement, Google is also announcing an upcoming training course for virtual reality content creators called the VR Creator Lab. Applicants chosen will start a three-month intensive course this August and get $30,000 to $40,000 to fund their dream project.
