Avaliação experimental de sistemas de rastreamento ocular do ponto de vista de ações de apontamento e seleção: um estudo de caso.

Abstract

The main objective of this dissertation is to compare the usability of two eyetrackers of the public domain (which use only the image captured by a conventional webcam), and a low-cost commercial eye tracker, the Tobii EyeX Controller, equipped with multiple dedicated cameras, during pick-and-click tasks on a desktop computer. This research has the following specific objectives: (1) to adjust partially the evaluation approach proposed by Queiroz (2001) to the context of pointing and selection tasks via eye-tracking; (2) to compare the nature of the problems identified from usability indicators of eye trackers; and (3) to determine which performance indicators of the confronted eye trackers positively impact on the subjective user satisfaction. It was concluded that the chosen efficiency indicators have shown satisfactory results for public domain eye tracker solutions. It was also concluded that the subjective user satisfaction indicator has shown best scores for public domain eye tracker solutions.
