A strong background in H.C.I., or Human-Computer Interaction, is a critical part of today's design of software and interactive products. While well-designed interactivity is not always necessary or even desirable, it can be critical for today's new products and interfaces. For designers, task analysis, usability testing and prototyping are all important parts in the process of creating interfaces and products which solve users' needs. The following are individual and group projects completed in H.C.I. classes at Stanford. This software prototype of the eScript, an electronic script for children's theatres, reflects the way theatre directors work with child actors as well as the special challenges they face. The eScript product concept, a group project in Terry Winograd and David Kelley's class, Interdisciplinary Interaction Design Project, also included a hardware prototype. Stanford tunnels is an interactive exploration of the legendary steam tunnels on the Stanford campus. This group project provided the opportunity for usability testing as well as insight into the challenges faced in creating a strong cohesive visual aesthetic. A "how-to" interactive experience showing how one aspect of the "Big Dig" project in Boston is being completed. This was as individual project for Human Computer Interaction Studio Design class.
