                     HOW  LIGHT  FIELD  VIDEOS  
HELPS  GOOGLE  FOR  
IMMERSIVE  AR,  VR  EXPERIENCE
INTRODUCTION
• A Google research team is experimenting with new technology than can pave way 
for more immersive Augmented Reality (AR) and Virtual Reality (VR).
• The recorded videos will allow users to move items within a video as well.

TECHNOLOGY
• The researchers have figured out a way to record a wide field of view scenes that 
can be streamed over Wi-Fi.
•  The technology also helps reconstruct and compress high-quality videos.

REASON BEHIND INNOVATION
• Photos and videos play a huge role in our day-to-day experience on mobile devices.
• The hope is someday immersive light field images and videos will play an equally 
important role in future AR and VR platforms.

HIGHLIGHT OF TECHNOLOGY
• The biggest highlight of the new technology is data compression.
• It will ensure the system is available to a wider number of users who may not have 
standalone AR or VR devices.

BENEFIT FOR USERS
• It does not reduce the original visual quality.
• Users will be able to stream this light field video content over a typical internet 
connection.

FEATURES
• Capturing
• Reconstructing
• Compressing
• Rendering high-quality immersive light field video
• Wide field-of-view scenes

DESIGN 
• To record immersive light fields, they use a custom, low-cost array of 46 time-
synchronized cameras mounted to a lightweight acrylic dome. 
• They produce 6DOF volumetric videos with a wide 80-cm viewing baseline, and a 
wide field of view.

SYSTEM REPRESENTATION
• A series of concentric layers with semitransparent textures are rendered from back 
to front.
• It brings the scene vividly and realistically to life and resolves the issue of 
synthesizing viewpoints.

SYSTEM REPRESENTATION
• This will enable users to experience a natural range of head movement as they 
explore light field video content.
• The final, compressed representation is lightweight and can be rendered on mobile 
VR/AR platforms or in a web browser.
