Overview of
Research
My research mainly consists of the study of Web design and
usability issues, computer-supported
cooperative work (CSCW) groups, as well as general
graphical user interface usability issues. Here are the areas that interests
me:

Dissertation Thesis:
Examining a Metric for Predicting the Accessibility of Information
within Hypertext Topological Structures
The scope of my dissertation
was to evaluate a proposed metric that I
designed. The metric is intended to
ascertain the accessibility of information associated with various
hypertext structures by determining if the derived information
accessibility index for these structures corresponds with other
tests of optimal hypertext accessibility (time, accuracy, and
disorientation). This metric takes into account the ‘shape’ of
hypertexts (i.e., depth, breadth, and topology).
The metric
was most accurate for the objective measures of search
performance, especially the number of deviations from the optimal
path, and the number of back-page commands for the more complex
hypertext conditions. It is concluded that
this metric could help serve as an accurate predictor of information
accessibility for various types of hypertext structures.

Augmented Interface Research |
| |
My current line of research consists of studying the
effects of human cognition on dynamic interfaces and hypertext structures
in an effort to help facilitate an augmented cognitive relationship
between humans and computer systems.
To accomplish this, cognitive, motor, and metacognitive factors
as they relate to computer systems
will be examined. These studies will provide
information as to how humans search for and find information within
these systems.

Web Usability & Internet Research |
|
I
am currently studying
ways to make the Web more accessible to the general public
–especially the young, elderly, and those with disabilities.
Specifically, this research is designed to investigate the most effective and usable Web
interface layouts, structures and, text for users of all abilities. This includes the
examination of various Web interface combinations as well as different forms of text,
graphics and, menu structures.

Graphical User Interface
Usability
|
|
I
am currently studying computer screen readability by varying the types of text
(faces and sizes), color mixtures (background and text), as well as different screen layouts
(i.e., varying the degree of white space, scrolling, structure, etc).

Computer-Supported Cooperative Work Research |
|
I
am currently studying ways to increase performance in CSCW environments. This involves the
examination of such things as participants' productivity, learning, and their degree of
satisfaction and consensus, as well as communication patterns as they converse via the
computer during the life of their group. These interactions mostly consist of
longitudinal, synchronous, three-way decision-making communication tasks between
individuals.
