8 Hvorfor bruge forskellige former for prototyping? Understøtte iteration og evaluering i design processen Interessenter kan bedre forholde sig til en prototype end et stykke papir Kommunikation mellem projektdeltagere Understøtter reflektion og valg mellem alternativer Friday, February 11, 2011

9 Storyboards Storyboards er (ofte) en yderligere detaljering af scenarier. Fremstilling af storyboards tvinger udviklere til at overveje input output devices anvendelse ift. brugsomgivelser hvilken information skal være tilgængelig på hvilket tidspunkt Friday, February 11, 2011

The same concepts apply in exploring ideas at a completely different scale, when designing a user experience set in a public and/or constrained environment. This example involves early exploration of ideas for the interior layout and components of an airplane. The design team together conducted a variety of bodystorming explorations within a full-scale foam-core environment simulating the inside of an airplane. Using props, such as chairs, readily available in the studio, the team enacted various social situations and activities such as sitting and reading, sleeping, and talking to a travel companion, receiving and eating meals, to evaluate ergonomic and psychological comfort with Again, many ideas for physical configurations could be tested in a time and money efficient manner. Additionally, the involvement of the whole design team created a common focus and a shared ownership of the design directions chosen for further development.

28 Egenskaber ved low fidelity prototyping Ligner ikke det færdige produkt Lette at modificere Billige, hurtige Gode tidligt i processen Uegnede til vurdering af visse egenskaber (lidt afhængig af prototypeform, f.eks. udførelsestider, teknisk realiserbarhed, detaljeret interaktion, æstetisk oplevelse) Friday, February 11, 2011

29 High fidelity prototyping Flash ;-) Visual Basic Smalltalk Java Phidgets Arduino Friday, February 11, 2011

30 Egenskaber ved high fidelity prototyping Tættere på færdigt produkt Mere realistiske tests Afhænging af værktøj og implementation: tid, æstetik, detaljeret interaktion kan vurderes Feasibility tests Godt til at sælge Tager lang tid at konstruere Friday, February 11, 2011

31 Trade-offs og kompromiser Der er altid trade-offs og kompromiser i udvikling af prototyper Horisontal vs. Vertikal Horisontal: mange funktioner skitseret, lidt detalje Vertikal: mange detaljer og få funktioner Friday, February 11, 2011
