An Investigation of Usability Issues with Mobile Systems Using
a Mobile Eye Tracker
By: Marie Norlien (2002)
A thesis submitted to the School of Information Technology
in partial fulfillment of the requirements for the degree of Master
of Science in Information and Communication Technology.
Abstract: Mobile systems raise
many usability issues that are not yet well understood. One technique
for acquiring data relevant to these issues is the use of a head-mounted
mobile eye tracker. The goals of this thesis are (a) to explore
the potential and limitations of an eye tracker in example studies
of one or more typical mobile systems and (b) to contribute some
insights into particular usability problems that arise with those
systems. This has been accomplished by understanding the current
relevant literature, use of the eye tracker, and exploratory usability
studies using the IRREAL pedestrian navigation software and two
market Global Positioning Systems (GPS) systems designed for a Pocket
PC. Current literature includes an overview of mobile systems, an
understanding of multitasking and how conflicts can arise, and a
discussion regarding navigation systems. Next, a background to eye
tracking including information regarding which eye tracker we used
in our studies is explained. In addition, problems and solutions
related to the use of a mobile eye tracker discovered during our
studies and uses with other mobile devices are presented. Finally,
our studies are conveyed along with their results and central usability
findings related to the particular mobile system, multitasking,
and the uniqueness of mobile systems. To summarize, the reader should
have a good understanding of the mobile eye tracker including its
strengths and limitations. In addition, it should be clear how the
use of a mobile eye tracker is an important evaluation tool for
studies with mobile systems. And last, the reader should have gained
an understanding of user multitasking issues related to mobile systems
and mobile environments with particular relevance given to navigation-based
systems.
