Design Method EssaySketching Prototypes

User Sketches: A Quick, Inexpensive, and effective way to elicitMore reflective user feedback - Tohidi et al 2006

Usual usability testing techniques elicit criticisms & comments,identifing problems, but DONT faciliate reflection to help generate ideas and alternative solutions

approach based on enabling the users to sketch for reflective, not reactive feedback

Sketching interfaces: Toward more HIDLanday & Myers (2001)

supports

Allows creativity by not forcing one to concentrate on unnecessary precision

sketching supports communication

encourages overal stucture and interaction rather than look and feel

no need for the visual design

excellent first draft tool

copy/paste can't do as easy on paper

a computed based sketching tool - SILK

Getting the right design and the design right: testing many is better than one. - Tohidi et al

good at identifying problems, not provising solutions.

giving alternative design solutions allows better feedback

Prototyping: Generating ideas or Cargo Cult Design?Holmquist 2005

to avoid cargo cult design a representation should be presented honestly as to what it is, an allow exploration in design

Even a simple representation fairs useful if it turns out to give new insights

Mockups/prototypes allow the freedom to explore without the the limitations of current technology

These representations must give a realistic impression inteded of the end product

Cargo cult design - fooling the users to think it is the real thing?or Creating a representation without sufficiant knowledge of how it would actually work, or presentinga representation without acknowledging such knowledge

Prototypes envision functionMock-ups envision form

Interaction designer works between both these worldsand as such must lend techniques from both

Webkit Tangible UI: A Casestudy of iterative prototyping. Stringer et al (2005)

this paper supports understanfing og designing for ubiquiious technology

Prolonged periods of iterative design helps the designer understand users and best use in theenvironment. in this case, class room, what makes it invisible

Explore app space without commitng too much effort into software or hardware development

initial prototype that invalidated idas of how TUI could help

quick, inexpensive test of many to evaluate with physical context of use

Iterative design particularly well suited for TUI design

dissapear into environment

In-situ iterative prototyping

designing for social consequence

Integrate technology into the social fabric of everyday life
