Naive Usability Assessment

The purpose of this assignment is to get you thinking in terms of usability, and noticing usability issues from the user's point of view.

Pick two times that you use some sort of technology or information system: a web site, an ATM machine, a car, a bicycle...the possibilities are many. Choose one that you have used many times in the past, and one that you are using for the first time.

For the length a transaction, or about 15 minutes, whichever is less, notice and record usability issues or problems. Pay attention to such issues as the following:

• instances in which you had to modify your own activity to suit the needs of the system or technology;
  
• moments of confusion or uncertainty, such as questions about what actions you should take or what a display or system response means;
• inconveniences, instances requiring added effort from you -- physical (e.g., doing something, or doing something in an awkward or effortful way) or mental (e.g., having to remember something that takes some effort).
• emotional reactions, such as annoyance ("why do I have to do this? why can't I do that?"), anger, fear ("will it eat my ATM card?"); pleasure, happiness ("That was fun!" "That's really convenient!"); whatever.
• added effort or attention of any kind.
• What's even harder to notice: times when everything went smoothly, without problems.

When you are using the system or item with which you have experience, these may be harder to notice.

Pay attention to the ways in which you have been trained by it to do things its way, the accommodations that you are now used to making. During the exercise, simply keep track of these instances as they arise. Stay with noticing the disjunctions between how you act and how the system works; do not leap into redesigning it to work better. This is hard; but premature re-design can lead to suboptimization: we solve some problems while creating new ones.

Summarize your observations in a paper, spending a page or two on each of the two instances. Then write an additional page or so reflecting on what you learned about usability from this exercise. Photos (or screenshots, or whatever) can be helpful. The point is not to apply any of the readings, but to notice your own experience as a user.

Write approximately 2 pages for each instance (the familiar and unfamiliar) plus one page reflection (total approx. 5 pages).
