This paper presents the motivation and results of identifying the point of observer's interest with use of the infrared eyetracker. This research is an introductory part of our project aiming at finding the irregularity of medical data distribution in electrodiagnostic signals by analysis of expert's eye trajectory during the routine recording inspection. For the novelty of our approach, before the eyetracker was used in cardiologists, various tests had to be completed assess the accuracy and the dymanic properties of the human oculomotoric system during simple visual tasks. The experiments were completed on three untrained volunteers each performed 20 simple tasks with use of OBER2 eyetracker. A part of results was verified using another system based on the electric dipole features of the eyeglobe. The final results are very important for the further research giving many practical considerations for the experiment itself and setting the borderlines for expected accuracy.
