Iterative prototyping is a crucial approach in design, particularly for tangible user interfaces (TUI). This method allows designers to explore various possibilities without heavily investing in software or hardware too early.
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
