Text focus for head mounted displays

This invention helps users focus on text in a head-mounted display by making everything else blurry. It uses an eye-tracker to figure out when you're reading, specifically by analyzing your eye movements and fixation durations. Once it knows you're reading, and after you've selected the text area, it blurs the non-text parts of the display, leaving the text clear.

Why it matters: Filed before advanced eye-tracking was common in consumer HMDs. Modern HMDs now frequently integrate sophisticated eye-tracking, making the necessary sensor data and real-time processing capabilities readily available for this software-based filtering.
