  The manuscript presented an analysis of the work in the field of eye-tracking
over the past ten years in the low-cost filed. We researched in detail the
methods, algorithms, and developed hardware. To realization, this task we
considered the commercial eye-tracking systems with hardware and software and
Free software. Additionally, the manuscript considered advances in the neural
network fields for eye-tracking tasks and problems which hold back the
development of the low-cost eye-tracking system. special attention in the
manuscript is given to recommendations for further research in the field of
eye-tracking devices in the low-cost field.
