Notes on IRB: (Updated August 2009)
IRB questions to melanie.clark@osp.gatech.edu |
This term you will undertake a group project (3-4 people) to evaluate some computing-related task/problem, to develop interface design alternatives for the task/problem, to implement a prototype of your design, and to evaluate your design. This project should provide you with hands-on experience with the tasks that interface designers face every day. Ideally, the topic of the project will be a problem that matters to some "real-life" people.
Theme: In order to provide some unity and shared understanding across the project teams, there will be an overall theme for the projects. See the Home Page for more on the theme for this semester. Think broadly about the theme. This is your problem space for the semester-long team project.
Each project group will be graded as a team, that is, each person receives the same grade. I will poll team members, however, to make sure that all members are contributing. Lack of participation may precipitate an individual reduction of grade. Within the team, you must negotiate on how much and what each person will contribute. Think carefully about your team members: Where do people live and what hours do they work? Where will you meet? What skills do the different individuals bring to the group (computing, programming, design, evaluation, statistics, etc.)? I would strongly encourage you to form a heterogeneous team full of individuals with varying skills.
Each part of the project will include a deliverable report. This report will be placed on the web in an electronic format (PDF, HTML, Word); a paper copy will also be handed in. Each team should have a "home" page which includes: 1) a brief (paragraph) description of the problem/task; 2) the team members; 3) Links to the reports for project parts 1-4 (no report is needed for part 0). The format of the reports for the individual parts is ultimately up to you, but there will be templates for the sections, to help your team know what to expect, and what is expected. In any case, it should be professionally prepared, concise yet expressive, grammatically sound, illustrative of your efforts and process, and easy to view and understand. A good design effort can easily be hampered by a poor communication of what was done. You can certainly use the class SWIKI for your project web page (create your own sub page under the Projects page).
Due date: See class schedule
This first part of the project is relatively simple. You must list
the members of your team and identify the problem area that you will be
working on. You also must set up your web project space that lists
your team name, members, and provides links to all of the project
deliverables.
Due date: See class schedule
The key goal of this first substantive part of the project is to
deeply understand that problem space that you are addressing, its set of
pertinent users, and the issues and constraints that are involved in
the problem. If the task has an existing system/interface, you should
perform an interpretive evaluation of that system to help you learn
more about it. Most important is to identify important characteristics
of the problem that will influence your subsequent design.
In class and in the readings you will learn about different techniques for acquiring this kind of information. Feel free to utilize the techniques that you feel are most appropriate to the particular task you are examining. Your report and deliverable for this part should deeply examine the problem of study. Who are the potential users? What tasks do they seek to perform? What functionality should the system provide? Basically, you are setting up a set of constraints for your subsequent design. What criteria should be used to judge if your design is a success or not?
More specifically, you should develop the following items in this
part, and you should communicate them through your report:
The last item in the list above is critical. Don't just describe the target users, tasks, environment, etc. You must also tell us how these attributes should/will influence your design. Are there any implications to be made from the user profiles and other data you learned? We will be very careful to look for this information in your report.
Due date: See class schedule
The key goal of Part 2 of the project is to use the knowledge gained
in Part 1, as well as that from class, to develop a set of design
alternatives for your problem. This is the stage of "informed brainstorming". These multiple design alternatives
should explore the potantial design space for the problem.
In this part of the project you will develop mock-ups, storyboards, and sketches of your interface designs. That is, you should provide pencil-and-paper or electronic images of the interface at various stages; you do not need to build a working prototype. Your design sketches should be sufficiently detailed for a potential user to provide useful feedback about the design, however. Along with your design mock-ups, you should provide a brief narrative walk-through of how the system will work. Perhaps most importantly, you should also include your justifications for why design decisions were made, and what you consider to be the relative strengths and weaknesses of your different designs.
The design process you follow here is important. Don't do the following: The group splits up and everyone creates one design, then these are all your alternatives to be turned in. This is not how a good, creative design process should work. It should be more like a brainstorming session with all team members present. You should seek to create some fundamentally different design ideas, concepts all over the potential design space for the problem you have chosen. The key is to push the boundaries of the space of design possibilities.
Your project report should include all the explanatory material mentioned above as well as all the design sketches, drafts, storyboards, etc., that you generated. If some of your sketches are on paper, either scan or photograph the material and convert it to an appropriate electronic format. Make sure that your report adequately reflects the design process that your group undertook. The key in this part of the project is to come up with many different design ideas, not just a small set of wiggles from some basic design. You should plan on turning in at least three different designs.
We will utilize one full class day as a poster session near the end of this part of the project. Each group will post some of their design ideas on a poster in class. Everyone will then circulate and interact with the designers. The idea here is that each group can use this opportunity to get feedback about their design ideas as they narrow their design space and head into Part 3 of the project.
Due date: See class schedule
In part 3 of the project, your group will implement a detailed
prototype of your interface.
You can use any prototyping tools that you would like to assist this process
(e.g., VB, Hypercard, Director, clay, paper, plastic, etc.). You should
be able to get much of the interface functionality working, but
clearly you will not be able to implement all back-end application
functionality.
Additionally, you must provide a set of initial usability specifications for your system and a plan for an evaluation of it. To develop usability specifications, consider the objectives of your design. For example, if you are working on a calendar manager, you might specify time limits in which you expect a user to be able to schedule or modify an appointment, or a maximum number of errors that you expect to occur. Basically, you should list a set of criteria by which your interface can be evaluated.
Further, this part of the project should include an initial evaluation plan for the system. What kinds of benchmark tasks would you have users perform to help evaluate the interface? What kind of subjective questionnaire would you deploy to have a user critique the interface? You will need to actually carry out some of this evaluation in Part 4, so you should do your best to set it up now. The key here is not to do some exhaustive description of a usability evaluation plan, but to motivate why the particular plan you propose is appropriate for this interface.
Note that developing an initial evaluation plan is also a good way to figure out how much of the interface you need to develop. You should be able to build and connect enough of the application functionality to be able to conduct an initial usability evaluation with the benchmark tasks as you are proposing here.
Your write-up for this part should include a description of your system prototype. You can include screen dumps to help explain it and text to describe how a user would interact with it. Discuss the implementation challenges you faced. Were there aspects that you wanted to build but were unable to do so? The key component to include in your project report is a justification of why you settled on the design that you chose. What's special about this particular design with respect your problem?
The report for this part also must include the usability specifications that you established and a description of the evaluation that you are planning. This need not be too detailed here as the actual evaluation will occur in Part 4. We will try to give you helpful feedback about your plan here to assist with the testing in Part 4.
After this part is complete, each group will demo their system for the professor.
Due date: Friday of the last week of classes at 5:00pm
See class schedule
In the final part of the project, your group will conduct an
evaluation of the prototype developed in part 3. You should utilize the
evaluation measures that you identified in that part as well.
We expect that your evaluation will involve sample users interacting
with your system. These users
will likely be your client(s) and maybe other students from class or
other people who would fit your target user population.
Give the users a few simple
benchmark tasks and have them interact with your interface. Closely
study what occurs. Deploy a
questionnaire to get their subjective feedback about the interface and
interaction.
Your write-up for this part should include the following components:
The key to this part of the project is not to simply describe your evaluation methodology but to rise above that and describe what you learned from it. Explain why you chose the benchmark tasks that you did. Why did you ask users what you asked? What conclusions can you draw from the studies? What aspects of your design "worked" and what failed to meet your specifications? If you had more time to work on the design, what would you now change and improve? Remember, no designer ever gets a system "just right." We will reward teams who honestly and carefully assess their design and who clearly provide a plan for its improvement.
Last week of classes
The design project will culminate in a second poster session in which each group
presents their system to the class, to their clients, and to visitors (e.g., HCI facutly and students). Each group
will be expected to have a poster, a system demo (if possible and appropriate), and be prepared to give a polished 5-minute summary and
walk-through of their design and prototype (that is NOT a lot of time!). It is important that you
do a good job communicating all your efforts for the semester, and interact with the poster viewers, engaging them and answering questions. You
want to make sure that your objectives in the project are discussed,
your system is clearly presented, and that your design process is
communicated. Also describe what you learned from your usability
study. Practice your presentation! Five minutes is NOT
long -- plan accordingly. This is very useful for the real world, in which it is often the "elevator pitch" that catches someone's attention, and interest in your project.
Note that there will also be people from the various Georgia Tech venture labs and incubators--the people that can recognize a commercially viable idea and help shepherd it to market! Nearly every year there is at least one project team that ends up taking their project out into the market, in one way or another. So be prepared to pitch! And be ready to answer questions about potential markets and users and even business models. This can be very exciting!
