The eyes never move smoothly over still text.Р В РІР‚СњР вЂ™Р’В®dmund Huey built an early eye tracker, using a sort of contact lens with a hole for the pupil. This is the typical pattern of eye movement during reading. This observation raised important questions about reading, questions which were explored during the 1900s: On which words do the eyes stop?

For example, Louis Р В РІР‚СљР Р†Р вЂљР’В°mile Javal observed in 1879 that reading does not involve a smooth sweeping of the eyes along the text, as previously assumed, but a series of short stops (called fixations) and quick saccades. In the 1800s, studies of eye movement were made using direct observations. 6.2 Eye-tracking of younger and elderly people while walking.6.1 Eye-tracking while driving a car in a difficult situation.

If the wearer jumps back into full VR, the display can go blank to signal that theyР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re no longer engaging with the outside world. That display creates the illusion of looking through the lenses of thick goggles and seeing a pair of eyes, although in reality youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re still seeing a real-time animated copy. Then, the image is projected onto an outward-facing light field display. The stereo cameras capture an image of the face and eyes inside the headset, and their motion is mapped onto a digital model of the face. The teamР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s prototype headset - which it revealed ahead of next weekР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s SIGGRAPH conference - adds a stack of lenses and cameras to a standard VR headset display. Matsuda ran with the concept, and over the next two years, he led a team in developing a svelter design. Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўBut I donР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t tell researchers what to do, because you donР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t get innovation without freedom to try new things.Р В Р вЂ Р В РІР‚С™Р РЋРЎС™ Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўMy first reaction was that it was kind of a goofy idea, a novelty at best,Р В Р вЂ Р В РІР‚С™Р РЋРЎС™ he notes.

A prototype of FacebookР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s reverse passthrough system.Р В РІР‚СњР В РІР‚С›ccording to the blog post, FRL chief scientist Michael Abrash - quite understandably - didnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t find the idea very practical. The result was basically Matsuda wearing a telepresence tablet showing a copy of his own face - which is arguably just as awkward but with a more intriguingly postmodern twist. The screen displayed a virtual rendering of his upper face, and custom-rigged eye-tracking cameras captured where Matsuda was looking, so his avatarР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s eyes could point in the same direction. A blog post explains that Matsuda started in 2019, when he mounted a 3D display onto an Oculus Rift S headset. ThatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s awkward if bystanders are used to seeing their friend or co-workerР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s uncovered face.Р В РІР‚СњР В РІР‚РЋRL scientist Nathan Matsuda decided to change this. But as FRL notes, the people around a headset user canР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t make eye contact, even if the wearer can see them perfectly. ItР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s useful for quickly dropping out of VR, and it can also enable a form of augmented reality by adding virtual objects to the camera feed. FacebookР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s Oculus Quest platform, for instance, shows users a passthrough feed when they step outside their VR spaceР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s boundaries.
