Practical information Updates on the website Additional material on UX Evaluation criteria

Prototyping techniques- An overview María Menéndez Blanco

User Centered Design (UCD) process

Overview From user research to conceptual design From conceptual design to prototyping Physical and digital prototypes Kinds of prototypes Low fidelity prototypes High fidelity prototypes

Low fidelity prototypes Quick and dirty digital/physical proofs of concept Communication device Limited set of functionalities Explore different concepts

Storyboards Sketches that show how the system works Based on scenarios Informal narrative descriptions Do not necessarily include the system Quick and dirty Paper-based Digital storytelling tools (iComic, storyboardthat.com)

Index cards Easy way to prototype interaction Mainly for digital designs (apps, websites) One card is one screen or task

Wizard of Oz Method to prototype software-based systems Interaction is “faked” by a person

Physical prototyping

Physical prototyping

Video prototyping Illustrate how people will interact with a system Prototype complex interactions Might embed other kind of prototypes within the video (e.g. storyboard, physical prototyping, Wizard of Oz) https://vimeo.com/85335088

High fidelity prototype Interactive prototypes Close to the final product Complete functionality But: Inefficient for proofs of concept Expensive to develop Time consuming

For this module Conceptual Design Describe the design process: Video prototype your concept Describe the design process: What is your domain? What are the assumptions/existing conditions? How do you propose challenging these assumptions?
