In Alice in Wonderland and Through the Looking Glass, Lewis Carroll established an absurd world that tickles the reader's mind with reversals and twists of the ordinary. Occasionally, in one's day-to-day encounters with other persons, one comes across people with an oppositional personality that suggests that they live in a Lewis Carroll world of sorts.

One of the tenets of contemporary industrial design is to develop user interfaces that are comfortable, obvious, easy to learn, logical, and safe. Human factors should be at the head of the list in product development and design. The fact that in many instances this seems not to be so is the impetus for this article. The intent is to provide teachers with some design exercises that will help students become more sensitive to the application of human factors in design development. Specifically, the focus is on controls.
