This project was part of the class "Human Factors in Computer Systems" in the College of Engineering.

The goal of this project was to create the best design possible for a car clock using an iterative process.

We were allowed to use only 4 subjects and had to present all details of the goals, process, results, and conclusions on one 8.5 x 11 sheet of paper (front and back.)

What we did

We used visual basic to create our car clock because it allowed for fast prototyping and testing. We began our initial testing with two very different clocks pitted against each other. The winning clock then went on to be refined using the feedback from our subjects. We continued this process through three test iterations and four designs, eventually ending up at our final clock design.

The users were timed for "think time," time to set hours, time to set minutes, and "other." In the end, we reduced total time to set the clock from 22 seconds in the first round to 12 seconds on the final design.

The biggest challenges for this project were the outside constraints placed on us by the instructor, including a limit on test subjects and report length (1 page maximum). However, these constraints were what made this a very memorable and worthwhile learning experience, as in the "real world" we will have limited resources of time, money, and attention. I found that I can convey an incredible amount of information in a very concise manner, and this skill will serve me well in the work place.
