An Empirical Study on Web Usability

Date: May, 2009
Advisor: Prof. Soussan Djamasbi

This project employs quantitative methods and analyzes usability and non-intrusive eye-tracking data of web users to investigate user experience and efficiency issues in finance-oriented web page designs;  


This study and its extension has been published in two conferences, the first one as a proceeding, the second one as a poster:
  • With Djamasbi, Siegel, Tullis, “Efficiency, Trust, and Visual Appeal: Usability Testing through Eye Tracking”, Proceedings of the 43th Annual Hawaii International Conference on System Sciences (HICSS), Kauai, Hawaii, January 2010;
  • With Djamasbi, Siegel, Tullis, “Tracking Users’ Viewing Pattern”, in Eighth Pre-ICIS SIG-HCI Workshop, Phoenix, Arizona, December 2009;

Measuring Network Impairments

Date: May, 2008
Advisor: Prof. Bengisu Tulu

The Internet, as a prevalent, inexpensive, but unpredictable infrastructure, presents quality challenges to real-time applications. This study aims at providing users of real-time applications with a prototyped approach to obtain real-time feedback of network impairments. An algorithm with its Java-based implementation that calculates and reports network delay, loss, and jitter was tested in a controlled environment. Results suggest that buffer size plays a key role in quality of feedback.

This study was selected to appear in a pre-ICIS workshop as a poster.
