Prototype Fidelity

Prototype Fidelity

Fidelity is the level of detail that content is rendered in the model

• Low-fidelity prototypes
• Midium-fidelity prototypes
• High-fidelity prototypes

Low-fidelity prototypes


does not look very much like the final product

    Create early representations of its content

     Akin to sketches that artist and designers create in early stages: vague and minimally           formed

     Early conceptualisations of page layouts, e.g. rough position of menu areas, banners, toolbars, and content areas

    Simple, cheap, quick to produce

    Some methods:

• Storyboarding
• Sketching
• Index cards
• Wizard of Oz

example sketches we use for Monday clinic application

Advantages & Disadvantages Low-Fidelity

Advantages

• Low-fidelity representations,such as sketches, differ from the final product in interaction design, visual appearance, and/or level of details. The method is quick & cheap which encourage iterative design idea try outs between/during usability tests. 
• † Quick Low-fidelity tests allows designers and users to focus on high-level interaction design and information architecture, rather than on details or visual style. 

Disadvantages

• Users might judge a low fidelity prototype as unprofessional.

• While Low-fidelity prototypes allow spontaneous changes for exploring interactions, they also sacrifice some realism.

• Limitations in navigation and flow while a control person has to “make the interaction”
