Hi, this is Wayne again with a topic “How Does Eye Tracking Work?”.
Thanks for watching tech, quickie click the subscribe button and enable notifications with the bell icon. So you won’t miss any future videos. So wouldn’t it be useful if you could instantly know where people are looking without having to stare back at them? Maybe you’re wondering if your crush is checking you out from across the room or maybe you’re, just hoping that no one can see you picking your nose inside the car. Well, we haven’t invented 360-degree Bionic vision implants yet, but there are a number of eye tracking technologies out there. That can at least hope your computer know exactly what you’re looking at, which has applications and feels from gaming to marketing to even psychology. But how exactly do they work? Well, it turns out there are a number of different ways to keep an eye on your eyeballs and the modern history of eye tracking goes all the way back to 1908, when psychologists, Edmund Huy developed a contraption that looked like a contact lens with the lens part Attached to a needle that would measure where the Iowas pointed. Of course, it wasn’t exactly comfortable to have a gadget physically touching the users eyes. So while we patiently waited for the Cubs to win another World Series, um other inventors push the field forward and, funnily enough, it was in Chicago in 1937 that another method of eye tracking was developed. That involves shining light onto a subjects eyes and exposing the reflections onto film to understand human reading patterns. Now, obviously, modern eye tracking systems have dispensed with physical film, but this strategy of examining light that reflects off your eyes is key to how consumer eye trackers work. Today, you see eye trackers like Toby, which are gaining popularity with PC gamers fire infrared light instead of visible light at your eyes.
So the tracker will disturb your vision, while you’re in the heat of battle. Now this light is usually shown in this specific pattern which lands on your eye, making it easier for the infrared cameras built into the tracker to keep tabs on changes in how the light is being reflected so many times per. Second, this camera will take infrared snapshots of the patterns on your eyes and process. These images to determine where you’re looking for gamers eye tracking is supported and quite a few popular games from indie titles to big-budget triple-a releases and can be used for everything. From looking around the cockpit to determining where your target radical will go in a shoot-’em-up game, and the technology is also showing promise for players with disabilities, who might find traditional controllers difficult to use or even VR gamers, who owns the more realistic experience of the headset Display adjusting to where their eyes are looking rather than just head movements, and this for outside the gaming world eye tracking has also been used across disciplines to figure out what people are most interested in meaning it has obvious applications for advertisers eye tracking Tech has already Been used in studies that have revealed things about which elements of an advertisement or a webpage best hold of viewers attention and what things might just be taking up space or even turning the viewer off.
So this has raised concerns about how the technology may be used in the near future. For example, if you look at the digital display the shopping mall containing an ad, is there an infrared camera watching your eye movements without your knowledge? Is it being logged somewhere? Well, websites end up being able to watch you through an eye tracker connected to your PC so that they can cook up even sneakier ways to serve you ads, but even though I tracking has plenty of applications in somewhat in the various fields. Other areas, like medical research, also stand to benefit from it tremendously, so you won’t need a fancy IR emitter and camera system to know that I’ll be keeping an eye on it and speaking of keeping an eye on things, are you tired of people keeping their eyes On you, online well, checkout tunnel bear the simple VPN app that makes it easy to browse privately and enjoy a more open Internet with total.
