Week+8+Readings


 * This is merely PART of the notes taken from the week 8 slides, not ALL! This is just for quick references and point forms you may want to remember, you should still study the notes in full yourself. ****


 * What is a prototype?**
 * Small scale model
 * sketches
 * storyboard
 * slide show
 * simulation video
 * inanimate object representative of the product (lump of wood as a PDA)
 * cardboard mock-up
 * software with limited functionality


 * Why do we prototype?**
 * evaluation and feedback
 * presentation to stakeholders
 * effective communication
 * encourages reflection
 * answers questions and supports in choosing alternatives


 * Low-fidelity prototyping**
 * cheap and different medium as final product – paper, cardboard
 * quick, cheap, and easily changed
 * eg. sketches of screens, storyboards, wizard of oz, post it notes, task sequences


 * Storyboards**
 * scenarios, role play
 * series of sketches showing the process of a task


 * Card-based prototypes**
 * index cards
 * cards represents screens
 * often used in website development


 * 'Wizard of Oz' prototyping**
 * a user interacts with a system, but the system and output/response is controlled by a person


 * High-fidelity prototyping**
 * uses materials expected in final product
 * looks close to final product
 * NOT a full system


 * Compromises in prototyping**
 * software based : slow response, sketchy icons, limited functionality
 * types of compromises:
 * horizontal: wide range of functions, little detail
 * vertical: few functions, lot of detail


 * Construction**
 * taking prototypes and creating the final product
