A review of the low-cost eye-tracking systems for 2010-2020

Earlier Eye-tracking was mainly used in studies of psychophysics or cognitive development, in the last decade, the reduction in the cost of technological equipment and advances in machine vision has allowed this technology to go far beyond the scope of disease diagnosis. Today Eye-tracking is used to support multimedia learning, help in browsing the web, and is widely used in real-time graphics systems, which is especially popular for video games. The main problem of modern Eye-tracking systems is their high price. Equipment with viewing angle accuracy of less than 0.5 has prices from several thousand dollars. In recent years, more than 800 peer-reviewed manuscripts published on the topic of eye-tracking in popular libraries. In the last 5 years, thanks to the development of deep learning in the field of machine vision, happened a jump, which allowed for the creation of eye-tracking devices in the low-cost range.
