Abstract

When speaking of eye-based interfaces the current studies fo- cus on either eye gaze or eye movement. Each of the different types of eye-based interactions introduces advantages and dis- advantages. In continuation of previous work, this research focus on the combination of eye gaze and eye movement to develop a new type of interface. The study aims to explore the possibilities of combining the different advantages both interfaces bring. The study includes an experiment to test this possibility and identify new research questions on this untouched topic. It is a small exploratory experiment, which tests how fast the new combined interface performs compared to an eye gaze-based interface. Additionally, the accuracy of the combined interface is also measured and compared to the eye gaze-based interface and a descriptive comparison is made to a touch-based interface. The study is based on the hypothesis that there is an improvement to the performance when using a combination of eye gaze and eye movement in the interaction between humans and computers, and the ex- periment is conducted using two null hypotheses. The study describe how the data is processed to be able to test the two null hypotheses using a paired t-test. At the end, I will discuss the validity of the study. The discussion includes thoughts on the size of the study and how it affects the sample size. Furthermore, I will account for the used equipment and how it affects the validity together with a discussion on how the current state of research is providing an advantage for popular interfaces.
