A software program stores during a recording session eye-tracking data and all other communication device activities of a test person that self-controlled confronts her/himself with display scenarios or virtual pages. The display scenarios are stored simultaneously either: 1. after a predetermined elapse time interval, 2. after recognizing a raised attention level of the test person, 3. after a positive result of a scrolling detection process. In a consecutive processing cycle, the software program utilizes an eye interpretation engine to derive high level information and visualizes them superimposed on the correlated image scenarios.
