CSIS 672

Human Computer Interaction


Section 1: W 5:30pm - 8:15 pm / HWE 300


Introduction to human-computer interaction and user-interface development. Topics include human factors of interactive software, interactive styles, design principles and considerations, development methods and tools, interface quality and evaluation methods. This course stresses the importance of good interfaces and the relationship of user interface design to human-computer interaction. It is intended for students whose future work may involve software development.

Prerequisites: Each student must have completed CSCI 230 (Data Structures and Algorithms) or an equivalent or higher course, or have permission of the instructor. Minimally, each student should have strong background in software development, data structures, and algorithms; also strong background in a high-level programming language such as Python, Java, or C/C++.

Assignments / Projects

Homework1, Homework2, Homework3, Final Project.


  1. Designers are not users by Jakob Nielsen, principal of Nielsen Norman Group.
  2. Heuristic evaluation involves having a small set of evaluators examine the interface and judge its compliance with recognized usability principles (the "heuristics"). See How to Conduct a Heuristic Evaluation, Usability.gov's Heuristic Evaluations and Expert Reviews, and Nielsen Norman Group's Heuristic Evaluation.
  3. The evolution of the desk - a thought-provoking, historically-accurate (almost) progression.
  4. Jacob Nielsen's usability pointers
    • Usability 101 -- How to define usability? How, when, and where can you improve it? Why should you care? This overview answers these basic questions.
    • How to talk to users during a usability test - "Echo. Boomerang. Columbo."
    • Silicon Valley HBO excerpt - the Pied Piper Platform Usability Test - "Totally Freaked Out" scene.
    • Ten Usability Heuristics -- Ten general principles for user interface design.
    • Progressive disclosure defers advanced or rarely used features to a secondary screen, making applications easier to learn and less error-prone, whereas staged disclosure provides a linear sequence of options, with a subset displayed at each step. Both are strategies to manage the profusion of features and options in modern user interfaces.
  5. NIME 2016 keynote lecture by Garth Paine - over the last two decades, the NIME community has seen an explosion of innovative and inspired ideas around the development of new musical interfaces. This lecture provides an overview of the field and important issues that emerge again and again, which may inform UI development in general.
  6. User personas
    • What are personas and why should I care? - a quick intro from the Nielsen Norman Group.
    • User personas - a user persona is a specific, imaginary example representing a set of real users - its an abstraction. As an abstraction, it focuses on the essentials, while abstracting away the unessentials.
    • Getting the most out of personas - personas are great, but they are all too often under utilized, or worse misused. Find out some tips for creating and using your personas, so that you can get the most out of them.
    • User personas - finding imaginary friends for UI designers.
    • Creating negative personas - how to plan for failure and user frustration.
  7. Conceptual Models
    • Conceptual models in a nutshell - explains conceptual models and describes why its best to develop the conceptual model of a system before its user interface.
  8. UI lifecycle
    • Mayhew's Usability Engineering Lifecycle.
    • # Scrum is a development process which incorporates all other development processes. It is agile and revolves around a theme of identify, implement, evaluate. It cuts through complexity to focus on building software that meets needs incrementally and empirically. Also see Scrum guide for term definitions (e.g., Sprint, Sprint Planning, Daily Scrum, Sprint Review, Product Backlog, etc.)
  9. User scenarios
    • User scenarios are the stories that your personas act out. Basically, user scenarios are thought exercises (though represented visually) in which you predict how certain types of users — represented by your personas — will interact with your UI in a given situation in order to complete a given goal.
    • Scenarios (from usability.gov).
  10. Use Cases
    • Use cases are written descriptions of how users will perform tasks on your system. Each use case outlines, from a user’s point of view, a system’s behavior as it responds to a request. Each use case is represented as a sequence of simple steps, beginning with a user's goal and ending when that goal is fulfilled.
  11. Paper prototypes
  12. UX/UI Prototyping Tools
    • The 7 Best Prototyping Tools for UI and UX Designers in 2016 - choosing the right prototyping tool will maximize efficiency while minimizing effort (choosing the wrong tool will waste your time, in the long term). Get to know a tool, before selecting it. Things to consider are: learning curve, type of UI (website, mobile app, desktop app, other, all), fidelity (low (sketch, wireframe), high (flow, interaction)), sharing (collaboration with teammates, users), skills required (easy, hard, programming required, visual design required), and cost (free, or how much).
    • How to choose the right UX prototyping tool - important thoughts on choosing the right tool for rapid prototyping of UIs.
  13. GOMS and Keyboard-Level Model
  14. Card Sorting
    • Card sorting is a relatively low-tech technique in UX design for using a group of subject experts or users to generate a taxonomy or hiearchical strucure of concepts or items. It is very useful for designing information architecture, workflows, menu structure, or website navigation paths.
    • Card sorting: a definitive guide - Card sorting is a technique that many information architects (and related professionals.) use as an input to the structure of a site or product.
    • Card sorting is a method used to help design or evaluate the information architecture of a site. In a card sorting session, participants organize topics into categories that make sense to them. They may also help you label these groups. To conduct a card sort, you can use actual cards, pieces of paper (and possibly software).
  15. Usability.gov - the U.S. Department of Health & Human Services website on all-things related to building useable products.
  16. Apple Watch "fails to excite" and is "a bit underwhelming" say designers - In April, Apple courted the design world by presenting the Apple Watch at a pavilion in Milan and holding a glamorous dinner for leading designers. So what do designers think of the product now – and why are so few of them wearing it?
  17. An introduction to pair programming. This 9-minute video describes what pair programming is, the do's and don'ts of effective pairing, and the pros and cons of pair programming.
  18. Lewis, C. and Rieman, J. (1994), Task-Centered User Interface Design - A Practical Introduction.
  19. Critchley, S., "Designing Musical Instruments for Flow", O'Reilly Digital Media, December 29, 2004. (If you ask musicians what they value most about making music, most of them will say — in some form or another — flow. Flow is that wonderful sense of being lost in your work, when "work" becomes joy. Time disappears, and so do distraction, anxiety, and just about everything else, yielding to a pure unity of creator and creation. So wouldn't it be strange if many of today's musical instruments were designed to prevent or destroy flow?)
  20. Intro to Python
  21. jythonMusic provides software for music-making and creative computing. It is a collection of Jython libraries for music, images, graphical user interfaces (GUIs), and connecting to external MIDI devices, smartphones, and tablets, among others.
  22. Color Scheme Designer and for user interfaces.
