Paper Abstract:
|
While it's easy to determine the physical characteristics of users (at least in a face-to-face situation), the cognitive characteristics are elusive. Most individuals don't even know if they have less than average working memory capacity or if their personality undermines their ability to notice detailed information. As product designers, we tend to design for ourselves firstif we can't use it, chances are it won't work for others as well. But if the product's interface serves its designer well, it's no guarantee that it will serve its audience with equal success. Cognitive blindness is a term used here to recognize the difficulty we all face when it comes to knowing how others think and how these cognitive processes are different from our own. For a simple example, consider the ability to remember a photographic image. Are you better then most at this task? How can we compare and judge the quality of visual memory? Did a person focus on details or the overall effect? Was the composition or color scheme more memorable? Did everyone see the same color? But while judging the quality of memory is difficult, finding errors is easierdid the person remember the color of the butterfly spots or not? This paper analyzes some common sources of human errors and provides a few suggestions for design compensations. The main theme is to design with human errors in mind: every product will fail, but designers can minimize and mitigate the most common errors and those with the worse outcomes. |
