Russian scientists have developed a new approach that can almost double the accuracy of eye trackers – devices that record exactly where a person is looking. The new development will expand the use of the technology in medicine, esports, and computer work. Details were revealed by the press service of the Central University.
Eye trackers are devices that monitor eye movement using infrared emitters and cameras. They detect glare on the pupil and determine exactly where a person's gaze is directed.
This is done using software that analyzes the position of the pupils and calculates which objects the attention is focused on.
Russian scientists proposed a two-stage algorithm that more quickly and accurately identifies the pupil and glare, and also groups objects in the image.
According to Professor Andrey Somov, the new approach makes the technology more accessible for mass use by reducing the number of errors and increasing accuracy in difficult conditions. Tests showed a significant improvement: when wearing glasses, accuracy increased by 64%, and in bright lighting – by 27%.
In addition, the algorithm can determine which part of the screen the gaze is focused on with an error of only 16 pixels – almost twice as good as previous indicators.
As noted by researcher Daria Pechenova, such technologies can be used in various fields. For example, a doctor will be able to assess a patient's condition by the peculiarities of their gaze, and a teacher will be able to understand which words a child focuses on when reading.
