Facebook is improving the 360 video experience by predicting where you will look

From the stage of F8, Joaquin Quinonero, Facebook's Director of Applied Machine Learning, described a new technique the company is using to improve the watching experience for 360 videos. The format is challenging to deliver because of its size, but Facebook is using machine learning to reduce the number of pixels that have to be rendered at any one time. By predicting where a viewer will look next, rendering priority can be given to that location -- particularly helpful for users with lower quality internet access. The status quo for 360 videos is reactive rather than proactive rendering. Mike Coward, engineering director for Facebook's VR video team echoed the frustration of users to me when he described the unpleasantness of turning your head in VR only to see a blurry scene.
