Learn about our test specifications and how you can repeat the tests, judge the quality of the products yourself and adequately compare different eye tracking systems in the market.
Tobii Pro has developed an extensive test method for remote eye trackers to measure and report quality of data our systems produce. The method is unique in the sense that it takes variety of likely user scenarios into consideration. It clearly defines accuracy and precision metrics and specifies experimental procedures under variant conditions, so you can easily understand and interpret specifications.
Researchers can repeat the tests, judge the quality of the products themselves and adequately compare different eye tracking systems in the market. An open source software tool developed especially for accuracy and precision measurements is supplied with the method to simplify the tests. The software is free for anyone to use.
The test specification includes ideal measurement conditions, large gaze angles, and different illumination sets and head positions in the head movement box. This ensures that the values specified are as close as possible to those actually used in a real eye tracking session, where a subject is allowed to move freely
