Design Method EssaySketching Prototypes
Webkit Tangible UI: A Casestudy of iterative prototyping. Stringer et al (2005)
Integrate technology into the social fabric of everyday life
designing for social consequence
In-situ iterative prototyping
dissapear into environment
Iterative design particularly well suited for TUI design
quick, inexpensive test of many to evaluate with physical context of use
initial prototype that invalidated idas of how TUI could help
Explore app space without commitng too much effort into software or hardware development
Prolonged periods of iterative design helps the designer understand users and best use in theenvironment. in this case, class room, what makes it invisible
this paper supports understanfing og designing for ubiquiious technology
Prototyping: Generating ideas or Cargo Cult Design?Holmquist 2005
Prototypes envision functionMock-ups envision form
Interaction designer works between both these worldsand as such must lend techniques from both
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
These representations must give a realistic impression inteded of the end product
Mockups/prototypes allow the freedom to explore without the the limitations of current technology
Even a simple representation fairs useful if it turns out to give new insights
to avoid cargo cult design a representation should be presented honestly as to what it is, an allow exploration in design
Getting the right design and the design right: testing many is better than one. - Tohidi et al
giving alternative design solutions allows better feedback
good at identifying problems, not provising solutions.
Sketching interfaces: Toward more HIDLanday & Myers (2001)
a computed based sketching tool - SILK
supports
copy/paste can't do as easy on paper
excellent first draft tool
no need for the visual design
encourages overal stucture and interaction rather than look and feel
sketching supports communication
Allows creativity by not forcing one to concentrate on unnecessary precision
User Sketches: A Quick, Inexpensive, and effective way to elicitMore reflective user feedback - Tohidi et al 2006
approach based on enabling the users to sketch for reflective, not reactive feedback
Usual usability testing techniques elicit criticisms & comments,identifing problems, but DONT faciliate reflection to help generate ideas and alternative solutions
