GOMS-TLM and Eye Tracking Methods Comparison in the User Interface Interaction Speed Assessing Task

摘要

The article describes a part of the ergonomic study of a mobile application user interface. It briefly presents the methodological review of the study, based on the of Schneiderman. This assessment was expanded by the GOMS-TLM method adapted for touch input and the eye tracking procedure on Tribe Eye Tracking equipment in the task of assessing the speed of a user interaction with an application. It has been demonstrated that the actual speed of the user, who is interacting with the test application for the first time, measured in eye tracking, is, on average, significantly lower than the prediction received by the GOMS-TLM method. It is higher the prediction for users familiar with the interface, however. Thus, in the work it was concluded that the GOMS-TLM method can give acceptable results that do not contradict the empirical oculographic experiment with minimal resource expenditure
