Todays assignment (12 minutes of observing)

In public place where you can see many people:

  • 2 minutes per person
  • Alternate person in group and person alone
    • 3 of each type
  • Every 15 seconds note the following:
    • Talking
    • Quiet
    • Phone
    • Tablet
    • Laptop
    • Other Device
    • Number of Companions
  • Send to me by 5

Here is the spreadsheet for todays data collection.

Do not forget today's homeowork, remember to copy and past the data requested into an email, not a screen capture):
Stroop Experiment (do not alter any setting, send summary data)
Feature and Conjunction Search (Run twice, ones as Feature search, once as Conjunction search, find this setting on the Methods Settings tab, change nothing else, send the data)
Memory Span (do not alter any setting, send summary data)
DRM False Memory (do not alter any setting, send summary data)


May 1, 2017

Here is the homework that is due tomorrow:

List the two most types of interactions that you do Discuss when and how you do these interactions Are there differences in how you do these interaction in different computer contexts? In what ways do you find the interaction effective, positive? In what ways do you find the interaction ineffective, negative? Write up and be ready to hand in tomorrow in class. We will also discuss.

Course Goals

Description of Topic

Human Computer Interaction is a field that examines how we interact with our devices, a broader term than computer, and tried to determine ways to increase the quality of thse interactions. Since we have both a human and a programmable machine, we have to deal with both human and machine tendencies, limitations, and strengths to maximize the quality of interaction between the two. As such we need to examine issues relating to both humans and machines and then methods for producing and assessing quality of interactions with these devices. The aim is to have these devices meet the needs and work with the strengths and limitations of the users. The phrase intuity is bandied about a lot. Let me say right here, that that is a meaningless phrase, but we can make the interactions easier to learn, remember, and use, and more enjoyable. Yes this is a psychology course as well as a computer science course. We need to understand the current methods of interaction but we also need two elements from psychology: We need a broad understanding of psychological issues of interaction (sensory, cognitive, and social), and we need methods for testing if our interactions work the way we believe they will. We will delve into this field to introduce the issues and methods for sound interaction design.


I have several goals for this course:

  1. To introduce you to the field of Interaction Design 

  2. To introduce you to the methods for testing interaction design

  3. To give you some experience in doing some facit of building or evaluating interaction design

  4. To develop your ability to answer questions

Course Expectations

  1. Attendance is Mandatory

  2. Read all material before class

  3. Actively participate in discussion (Hint: you cannot do this item if you do not do item 2)

Assignment Descriptions

Homework (for lack of a better word)

Periodically, I will ask you to perform an assignment out of class. Some of these assignments are listed in the syllabus already (these have links so they are convenient to place here). For those listed, you will need to get the requested information to be by 5 pm of that day. I will show you exactly what to send in class on that day. For other assignments you will need to bring them to class. I will grade them on a completion basis. Full marks for doing them, no marks for not. Should be easy to get all the points. What bet do you want to make that not all of you will even get an A on this part of this assignment? Prove me wrong!


On Tuesday of the second week (May 9) and Tuesday of the last week (May 23) we will have an exam covering the material of the course.  The exams will be both short answer and essay.  You will get the essay questions from which I will draw the questions two days before the exam.  The essays will be designed to ask you to apply the material from class on isues of interaction design. The material will cover both text and in class discussion.

Final Project

To culminate this class, you will do a project to deepen your experience with human computer interaction you will engage in one of the two folowing projects, depending on if you are in the PSY or CS class number: 

PSY Final Project

For your project you will begin the process of developing an interface for a web-based statistics app that is being developed by Haris Skiadas, Barb Wahl, and Bill Altermatt. You will develop the interface requirements for the project and design a first draft of an interface for the home page for the app. This is a real project that will have real world impact if you do it well. You will meet with the developers and also students using the methodologies we discuss in class. At the end of the semenster you will make a presentation to the developers of your proposal and I will forward your final report to them as well.

CS Final Project

For your project, you will use a program or app that you have developed in one of your CS classes that has an interface. You will follow the methodologies that we discuss to devise an improved interface and implement the improvements. You will demonstrate the original interface and discuss your improvements during the last week of class.
