INFO 608 Human-Computer Interaction
Spring 2009, Prof. Gerry Stahl, online section
[email protected]
Design Project Description
INFO 608 focuses on the design and evaluation of interactive systems from a user-centered
perspective. This project will explore how people and groups of people perceive, use, share and
communicate about information, and how interaction technologies can take these human issues into
account. It will involve the basic design principles and evaluation techniques in the field of human-
computer interaction (HCI). Work on this project does not presuppose any special skills; there is no
programming involved.
When you have completed this project, you will have had experience in:
• Finding and interpreting research literature in the general areas of study within the field of
human-computer interaction.
• Analyzing the interaction between people, the work they do, the information systems they use,
and the environments in which they work and learn.
• Analyzing the design of interactive computer systems from a user-oriented approach.
• Analyzing the results of the evaluation of interactive computer systems from a user-oriented
approach.
This project is intended to give you hands-on experience in actually designing and evaluating human-
computer interaction and computer-mediated human-human interaction. This ten-week design project
will take you through a design and evaluation cycle.
The project will also give you a taste of leading-edge, future-oriented research in HCI. The hands-on
design project this quarter will explore interaction design for a particular problem that illustrates the
course issues. The problem for the weekly group design assignments is:
Design new functionality for the Internet Public Library (IPL). The new functionality is
to support collaborative browsing and the co-construction of literature reviews by small
groups taking advantage of IPL and other search resources.
This design problem is typical of leading-edge research. It is also a real-world challenge: your ideas in
this course may be adopted within the IPL system managed by the iSchool at Drexel.
We will approach this problem systematically using HCI methods of task analysis, system design and
user-centered evaluation. During the quarter, teams of students in the course will develop interface
design concepts and present and document their solutions to these design problems.

Collaboration in the Project

The project is intentionally open-ended. It is not narrowly defined by the instructor. It involves dealing with a real-world wicked problem. That means that there is no correct solution to the problem, although some proposed solutions can legitimately be judged better than others. There is substantial room in the project for individuals and groups to be creative. The project is to be conducted collaboratively. That does not mean to break it down into a series of tasks for individuals to do separately and then glue the pieces together for a group report. Groups should brainstorm how best to approach each week’s assignment and should discuss together the main issues and components of a proposed group product each week. The best way to work collaboratively is to interact synchronously, at least at key points of a weekly assignment—such as brainstorming an approach and focus, reviewing resources gathered and organizing a group report or product. For an online course, this means that each group must find some times during the week when most members can meet together at the same time in a chat room. Group members who miss a meeting must be willing to make extra efforts to catch up on what they missed and to make extra contributions to the group effort. Groups are free to organize themselves. For instance, members can volunteer to take on certain roles in supporting the group process. Everyone should take responsibility for group success and should contribute approximately equally. Everyone should contribute based on their own skills and knowledge, while learning from the skills of others in the group.

Weekly Schedule of Design Project Assignments

The weekly assignments are coordinated with the readings. In particular, the textbook chapters and other readings often explain concepts and techniques needed for the assignment that week or the next. Wk Dates Textbook Readings Design Project 1 March 30

  • April 6 Ch. 1 & 2 “Social info foraging”, “Collaborative web search” Literature search on collaborative searching 2 April 6 - 13 Ch. 3 & 4 “Ariadne interface”, “Collaboration in a digital library”, “Browsing is a collaborative process” Literature search on collaborative browsing 3 April 13 - 20 Ch. 5 & 6 “As We May Think”, “Walden’s paths”, “Educational paths” Analysis of literature search group process 4 April 20 - 27 Ch. 7 & 8 “Computer-supported collaborative learning: An historical perspective”, “Social & collaborative filtering” Problem statement and task analysis Individual assignment : Midterm Reflection Paper 5 April 27 - May 4 Ch. 9 & 10 “Augmenting human intellect”, Engelbart interview Establish requirements with scenarios, task analysis, use cases 6 May 4 - 11 Ch. 11 & 12 “Five reasons for scenario-based design” Individual assignment: Conceptual design paper 7 May 11 - 18 Ch. 13 & 14 Heuristic evaluation readings Interactive prototype and scenario 8 May 18 - 25 Ch. 15 Cognitive walkthrough readings, Heuristic evaluation of prototype

Week 5. Establish requirements with scenarios, task analysis, use cases

Refine the problem statement and task analysis from the previous week by using it to establish software requirements. You may use a scenario with user persona. You may also define use cases for a couple of the most important new functions that you think are needed, like adding a new source to an annotated bibliography. Consider some of the possible functionality for collaborative approaches to searching, browsing and compiling literature reviews or annotated bibliographies. The interfaces for IPL and Blackboard’s virtual classroom already incorporate many useful functions; you may just want to redesign the way they are laid out and how they support group workflow. Consider how best to incorporate Internet browsing, uploading and downloading source documents, compiling reviews, adding user ratings, tagging, storing bibliographic data in EndNote, annotating, organizing bibliographies. Consider synchronous and asynchronous workflows. Consider tabbed vs. windowed interfaces and what is displayed on the computers of different group members.

Week 6. Conceptual Design

This is an individual assignment. You may discuss your ideas with the rest of your group and even coordinate your conceptual designs. However, each person must write their own paper describing their conceptual design. Read what the textbook says about conceptual design. Reference readings and findings from the class literature reviews to support your approach. Provide a rationale for your approach. Consider alternative approaches or designs and state the pros and cons of your choice. Your paper should be about 5 single-spaced pages long. Save your paper in Word format, using your last name as the file name, e.g., stahl-conceptual-design.doc. This is an individual assignment and should be uploaded to the Dropbox by midnight on Monday.

Week 7. Interactive prototype and scenario

Your group should review the conceptual designs submitted by its members or by other classmates. Decide on a conceptual design that the group will adopt for the rest of the quarter. Develop a low- fidelity paper prototype of the interface for new functionality of the Internet Public Library (IPL) to support collaborative browsing and the co-construction of literature reviews by small groups taking advantage of IPL and other search resources. Develop a scenario of use of this interface that exercises and illustrates its main new functionality. Develop a storyboard-like sequence of interface views that step through this scenario. The scenario and sequence of views will have to be adequate for the heuristic evaluation and cognitive walkthrough in the following weeks. You may want to use screenshots of the current IPL interface or other interfaces like Blackboard’s virtual classroom and add new buttons, etc. You may want to design your interface in HTML, PowerPoint, Paint, Flash or Photoshop.

Week 8. Heuristic evaluation of prototype

Select the prototype of another group to evaluate. Your group should all do heuristic evaluations of the same group. Announce your selection on the wiki; do not select a group that has already been selected. Decide how your group is going to conduct its heuristic evaluations. Then each member of the group should go through the heuristic evaluation checklist and document problems found. Finally, the group should review all the findings and produce a consolidated report of recommendations for the group whose prototype they evaluated.

Week 9. Cognitive walkthrough of scenario

Conduct two or three cognitive walkthroughs of your group design, following a scenario that steps a user through the screens of your prototype to accomplish some typical tasks. Read how a walkthrough is typically conducted and decide as a group how you want to adapt this process to your online setting.

Week 10. Final Design

Revise your interface design in response to the findings of the heuristic evaluation and the cognitive walkthrough. Post the group final design to the wiki by midnight Thursday, June 4.
