AR and VR are gearing up for a giant leap forward thanks to advancements in eye-tracking technology. The industry has been experiencing a boom in recent years with hundreds of startups and heavy investment from tech giants including Google, Apple, Samsung, and Facebook. Despite all the activity, AR/VR hardware remains relatively crude. Most interfaces take cues from head movement and manual inputs. Graphics often appear artificial, and can be harsh on the eyes due to low resolution and slow frame rates.
