It's not visible to the naked eye, but some manner of filter inside my webcam picks up hotspots on my chest where the infrared is being reflected. One thing I've noticed using the Tobii Eye Tracker is its infrared reflection gets picked up by my Logitech webcam.
I have far too many bundles of 6-foot USB cords in and around my PC as it is, so having an extension I can choose not to use, instead of tying up with a strap and adding to the bundle of wires already around my PC, is great. It's a nice addition to the box, because it gives the option of extending only when and if you need to extend. The Tobii Eye Tracker 5 includes an extra female-to-female USB extension, if your PC is on the floor, or otherwise too far from your monitor for the cord on the unit itself. You just stare at a few small, spinning dots on the screen until they burst, and once you've stared at enough, it's off to the races. Calibrating it might be the most fun you can have while calibrating an infrared instrument, although I'm not an engineer so I can't say that authoritatively. You just plug the Tobii Eye Tracker 5 into your PC via USB and it walks you through the set-up and calibration process. In fact, I almost feel like even if I didn't have the bothersome raised lettering on the front of my monitor, I'd prefer using the rugged velcro solution designed to adapt to curved monitors. Since the Dell logo on my monitor gets in the way, I just attached the curved-monitor adapter and it works great. Since the Tracker is held to the brace by the power of magnetism, it's easy to pop on or off. The Eye Tracker itself mounts magnetically to the plastic mount, and the whole thing is rock-solid. The Velcro pads are no joke: this is like the legit, real-deal stuff that you see in commercial or military applications, and as such, it holds on super tightly. The curved mount is in two parts: an adhesive velcro pad you stick on the bottom of the monitor, and a small plastic mount that mates to it. My monitor has raised lettering on the "Dell" logo right where the adhesive is supposed to be, which would have been a problem with the last version I tested out, but the Eye Tracker 5 includes a mount for curved monitors I slapped on the bottom of my display. A magnet on the Tracker itself keeps it in place, and lets you easily remove and replace it as you see fit. In the box is a small, metal strip with an adhesive backing you attach to the bottom of your display. Setting up the Tobii Eye Tracker 5 is a snap. Tobii Eye Tracker 5 Set-Up and Installation Here's what we thought of the latest entry into the Tobii Eye Tracker hardware family. While you're able to do everything you could do before, the Tobii Eye Tracker 5 does it better and more accurately than before.
The non-gaming software used for Windows functionality remains largely unchanged from the Tobii Eye Tracker 4C I reviewed in 2017 in functionality. Advanced image-processing algorithms and a physiological 3D model of the eye are then used to estimate the position of the eye in space and the point of gaze with high accuracy.The Tobii Eye Tracker 5, as the name suggests, is the newest version of Tobii's eye-tracking system, and like previous versions, it works so well in games that support it, I don't know if I can go back to playing without it. Near-infrared illumination is used to create the reflection patterns on the cornea and pupil of the eye of the subjectand image sensors are used to capture images of the eyes and the reflection patterns. Tobii eye trackers are an improved version of the traditional PCCR remote eye tracking technology (US Patent US7,572,008). We can then calculate a vector formed by the angle between the cornea and pupil reflections-the direction of this vector, combined with other geometrical features of the reflections, is then used to calculate the gaze direction. The image captured by the camera is then used to identify the reflection of the light source on the cornea (glint) and in the pupil. The basic concept is to use a light source to illuminate the eye causing highly visible reflections, and a camera to capture an image of the eye showing these reflections. However, when it comes to remote, nonāintrusive eye tracking the most commonly used technique is pupil centre corneal reflection (PCCR). There are several different techniques to detect and track the movements of the eyes. Eye tracking has long been known and used as a method to study the visual attention of individuals.
