Cheap eye tracking11/6/2022 ![]() ![]()
For gaming and VR enthusiasts, eye tracking holds a great deal of promise for a new level of control and immersion. CHEAP EYE TRACKING SOFTWAREThat’s still a bit lacking, though, because it is after all just a snapshot of a moment so the software also gives you all the eye tracking metrics, so you can quantify everything and get a more comprehensive overview of the performance.įor researchers, eye tracking offers new ways to understand human behavior, which will benefit marketers, sure, but also those who are looking for ways to make people’s lives better. CHEAP EYE TRACKING FULLYou can also go back and view the full video recording at a later time.įor any frame of the video recording, though, you can take a still and have the software superimpose a “heat map” on top of it that shows where the subject’s eyes traveled and for how long. For example, if you created a new ad display for your store, you can sit there and watch how subjects look (or don’t look) at the display. You can see what the subject is looking at in real time, and that’s helpful, but that basically just provides anecdotal data. CHEAP EYE TRACKING PROThere is, of course, a software analytics component to all of this, in the form of Tobii Pro Lab software. You can just swap out the non-prescription plastic lenses on the device for ones that have your prescription, and away you go. There are a couple of ways around this: One, obviously, is that you can just wear contact lenses, but for blind, bespectacled nerds like me, Tobii has a prescription lens kit. I did have to remove my glasses before using the Pro Glasses 2, though. The Pro Glasses 2 were light on my face-hardly any heavier, it seemed, than my own glasses. He added that calibration takes between 5-15 seconds. In this case, it’s just a one-point calibration,” Bartels noted. “Typically, a dot on a screen that you have the person follow around with their eyes. There is a quick calibration to set you up as a subject, but you just aim the glasses at a dot on a card for a few seconds, and off you go. And that’s the point: It’s designed to distract the subject as little as possible while collecting as much data as possible. However, there’s really nothing to describe: I put on the glasses and looked around, and my data was pumped to Bartel’s laptop. The data remains intact and available later.Īt this point in the article, we’d normally expend some digital ink describing the experience of the demo. All you lose is the ability for the researcher to keep an eye on things in real-time. If you lose that connection, though, despair not the data is still being recorded locally on the hip-mounted device. CHEAP EYE TRACKING PCVia a Wi-Fi signal the device createsVia any available wireless network (which may be advantageous when the subject needs to move distances beyond 50 feet or so)Tethered to the PC via a LAN cable There are three ways for the glasses and recording unit to connect to the PC: (There is a small lag to the video feed, but that’s inconsequential in this case, because the subject never sees their own live video.) The system connects to a PC-in the field, usually a laptop or Windows tablet-so the researcher can see what the subject is seeing, all in essentially real time. “It tends to be about half an hour of data per gigabyte,” Bartels told me. That 32GB may not sound like much, but the eye tracking produces a surprisingly small amount of data. “This is where the magic happens of marrying the eye data with the synced camera video,” said Bartels. The device is primarily for storage-it comes with a 32GB SD card-but it also processes the eye data. That data is fed into a small recording unit that loops onto your belt. CHEAP EYE TRACKING 1080PThe middle portion, between your eyes, contains a wide-angle camera that can shoot 1080p HD at 25FPS with a 90-degree field of view (FoV), a microphone, and a gyro and accelerometer. The aluminum, plastic, and stainless steel frame of the Pro Glasses 2 is essentially one piece that runs from ear to ear with a pair of lenses stuck to the front. The glasses’ hardware tracks all of the wearer’s eye movements, and the laptop’s software uses that data to map everywhere that person looks.įor example, if you’re a grocer and want to know the optimal placement for certain products on your shelves, you could send Pro Glasses 2-wearing subjects into your stores, and in little more time than it takes a person to complete a stroll down the store’s aisles, you would get a look at where the subject’s eyes landed, when, and for how long. Simply put, a subject dons the spectacles and walks around, looking at things, while a researcher hangs back and watches a live video feed from the glasses on a laptop. ![]()
