Document Summary

Lecture 4: prototyping: users can react to the design and suggest changes, types, sketching, low-fidelity (low commitment) vs medium-fidelity vs high-fidelity, prototyping methods, vertical, horizontal and scenario prototyping, sketches, storyboarding, pictive, scripted simulations, wizard of oz. Pictive plastic interface for collaborative technology: designing w/ office supplies (sticky notes and plastic overlays, session videotaped for further analysis. Medium-fidelity prototypes: simulations of some features done on the computer, provides sophisticated but limited scenarios for the user to try, dangers, users are reluctant to touch the design, challenge the designer, may think its real. Integrating prototypes and products: throw-away, just to get a reaction. Incremental: each individual component is created and tested, and may be added to final, evolutionary, prototype altered to incorporate design changes, eventually becomes the final product. Painting/drawing packages: draw each storyboard scene on the computer, doesn"t capture the feel" of the system. Scripted simulations: storyboard w/ media tools; simple prototype, user is given a specific, small task to follow.
