The Eye Tribe’s device uses a camera to track the user’s eye movement. The camera tracks even the most minuscule of movements of the users’ pupils, by taking the images and running them through computer-vision algorithms.
An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human-computer interaction, and in product design.
Now the team is back with a consumer product, the $199 Eye Tribe Tracker Pro, a version of the system that can be used by nearly anyone. Considering most eye trackers are about $20,000, this is a big deal.
The eye tracker consists of sensors— a camera and projectors —as well as image processing algorithms. The sensors, consisting of custom components and advanced optics designed for performance: Advanced micro projectors beam Near-Infrared (NIR) light, creating a reflection on the user’s eyes.
Tobii Eye Tracking devices are using near-infrared illumination to create reflections on the eyes that can be tracked with high accuracy. Light emission that meets this standard is not harmful to the human eye.
Now, thanks to innovation in the fields of gaming and virtual reality (inspired by potential profit with two huge consumer bases), eye gaze is not only getting better, it’s getting more affordable! Priced at $150, the Tobii 4C is the first affordable eye-tracking system.
There are many factors that drive the price of eye tracking hardware – usability, flexibility, support, compatibility with advanced modules (e.g. scene camera, multi-display, cognitive workload, etc.). In most (though not all) cases the higher end systems make use of more precise data to offer a more robust solution.
The Pro Glasses 2 start at $10,000, if you wish to conduct your own research, but you can hire Tobii to run a project for you, too. The latter has a typical cost range of $10,000-$30,000.
This technology is used for people who cannot control a computer or a tablet by standard methods such as a keyboard or a mouse. The staff at the Solution Outreach Center at OCCK, Inc. have used this technology with people as young as 9 months to senior citizens.
The First Eye Tracker In 1908, Edmund Huey built a device which could track eye movement during the reading process. This first eye tracker was very intrusive as readers had to wear a type of contact lens with a small opening for the pupil.
The way it works is that an eye-gaze camera tracks the person’s eye movements, which then moves the mouse on a computer screen. The person selects items either by holding their eye-gaze for a certain time, referred to as ‘dwell’, by blinking, or by clicking an external button.
You can also turn off eye tracking for all apps by going to Settings > Privacy > Eye tracker and switching Let apps use my eye tracker to Off.
Enable Windows eye tracking
An eye tracker lets your PC know where you are visually focused, giving you an extra input mode when it comes to gaming. It also makes the interaction feel more real. Your experience becomes richer, and your instincts extend into the game itself.
