Currently Teaching

HCIN-600
3 Credits
This course provides students with an introduction to the practical application of various research methods that can be used in human computer interaction. The course provides an overview of the research process and the literature review, and provides experience with qualitative, survey, and experimental research methods. Students will study existing research and design and conduct studies. Students will need to have taken a statistics course before registering for this class.
HCIN-620
3 Credits
Designing meaningful relationships among people and the products they use is both an art and a science. This course will focus on the unique design practice of: representing and organizing information in such a way as to facilitate perception and understanding (information architecture); and, specifying the appropriate mechanisms for accessing and manipulating task information (interaction design). This course will also explore the various design patterns (design solutions to particular problems) that are appropriate for the HCI professional. Students will need prior knowledge of an interface prototyping tool.
HCIN-630
3 Credits
This project-based course will focus on the formal evaluation of products. Topics include usability test goal setting, recruitment of appropriate users, design of test tasks, design of the test environment, test plan development and implementation, analysis and interpretation of the results, and documentation and presentation of results and recommendations.
HCIN-700
3 Credits
Human-Computer Interaction (HCI) is an evolving field. This course is designed to study the current themes and advanced issues of HCI. Topics will vary depending upon current research and developments in the field.
ISTE-266
3 Credits
This course will explore the design, evaluation, and use of computing and information technologies to benefit people with disabilities and older adults. Students will learn how to analyze the accessibility of existing software or websites, and they will learn how to design technology that can be effectively, enjoyably, and efficiently used by people with diverse sensory, motor, and cognitive abilities. Students will learn about cutting-edge ways in which science and technology has provided assistance and accessibility for people with disabilities. Students will learn how to investigate the needs of users with disabilities, design technologies according to universal design or accessibility principles, interpret key accessibility regulations and guidelines, and include people with disabilities in the design and evaluation of new technologies. Programming is required.
ISTE-798
3 Credits
This IST seminar course provides an opportunity for special one-time offerings of graduate topics or allows faculty to pilot possible new graduate offerings. Specific course details (such as the course topics, format, resource needs, and credit hours) will be determined by the faculty member(s) who propose a given seminar offering.
ISTE-799
3 Credits
The student will work independently, under the supervision of one or more faculty advisers, on a topic of mutual interest that is beyond the depth of or not covered in other courses.
