The Problem Solver – AI to help VR Display

To resolve the issue of latency and motion blur in VR headsets LG and a team from Sogang University have developed an AI based technology. A chance for them to head the race of higher resolution in VR headsets.

A major problem that VR hardware devs face is low motion-to-photon latency. It is actually the time between input movement to its reflection in the VR display. Higher latency rate can cause nausea. Same problem has given dare to even higher resolution VR headsets. Although, the issue has been solved in most of the consumer versions of VR headsets. LG and Sogang’s new AI technology has two big challenges; one is latency and the other is motion blur in VR display.

“The core of the newly developed technology is an algorithm that can generate ultra-high resolution images from low-resolution ones in real time. Deep learning technology makes this conversion possible without using external memory devices. The AI-based setup cuts motion to photon latency and motion blurs to one fifth or less the current level by slashing system loads when operating displays for VR.”

Power efficiency and higher resolution can be boosted by this technology in mobile headsets. The team has created a precise motor device to test system’s latency and motion blur. It simulates movements of neck and optical system based on human visual system.

For wide field of view in VR headsets, an 18 Megapixel, 4.3-in 1,443-ppi 120Hz OLED display is produced by the collective efforts of LG and Google. The panel is “world’s highest resolution OLED-on-glass display” according to Google.
