What type of measure is eye tracking?
Put simply, eye tracking refers to the measurement of eye activity. More specifically, eye tracking describes the recording of eye position and movement in an environment based on the optical tracking of corneal reflections to assess visual attention.
How accurate is eye tracking?
Accuracy and Precision of Gaze Tracking Accuracy is often reported by manufacturers to be < 0.5°. However, in particular for remote eye trackers, offset from the true gaze point is often found to be larger than 1° [5, 30], even in controlled environments.
How accurate is Tobii eye tracker?
We found that for adults, the mean group accuracy was within Tobii’s advertised specifications of 0.4–0.9°, and the precision measures were within or very close to the specifications of 0.04–0.15°.
What is Web gazer?
WebGazer. js is an eye tracking library that uses common webcams to infer the eye-gaze locations of web visitors on a page in real time. js runs entirely in the client browser, so no video data needs to be sent to a server, and it requires the user’s consent to access their webcam.
What is eye tracking in SEO?
Eye tracking is a piece of technology which enables users to follow the eye movements of an individual. This technology enables users to track the path of the viewer’s gaze across the content, while also detailing the order in which they look at these elements.
What is cognitive eye tracking?
Understanding cognitive processes Eye tracking is an unobtrusive method to gain deeper understanding of cognitive processes, such as problem solving and decision making. By measuring eye movements, researchers get insight into the ongoing mental processes during tasks. Eye tracking is used to study: Attention.
What is the scene camera module for eyetracking?
The Scene Camera Module within EyeTracking’s EyeWorks™ software opens a whole new feature set for your eye tracker. Move away from eye tracking on a computer monitor and track against mobile devices, tablets, printed brochures, musical scores, and even in a car.
Does eye tracking accuracy and precision vary between users?
We showed that there is large variability in accuracy and precision when eye tracking is used in more practical condi- tions. Differences between users can be more than six-fold, and we analyzed variations of trackers and screen regions. 2. We propose a way of formally going from measures of accuracy and precision to target sizes.
What is the accuracy of remote eye trackers?
Accuracy is often reported by manufacturers to be < 0.5°. However, in particular for remote eye trackers, offset from the true gaze point is often found to be larger than 1° [5,30], even in controlled environments. Factors that influence tracking quality
How can eye tracking revolutionize human-computer interaction?
CONCLUSION Eye tracking has the potential to revolutionize how we interact with computers. Attentive applications seamlessly integrate gaze input into existing interaction paradigms and explicit gaze control opens new design spaces for HCI.
