HCI 3. Rapid Prototyping 2013. Fall
Paper Prototypes & Mock-up Use Stage-Appropriate Tools
Outline Storyboarding Creating paper prototypes Testing paper prototypes Digital mock-ups
Storyboarding Isn’t about “Pretty pictures” It’s about communicating ideas (visually) * Star people
Storyboards should convey Setting People involved Environment Task being accomplished
Storyboards should convey Sequence What steps are involved? What leads someone to use the app? What task is being illustrated?
Storyboards should convey Satisfaction What motivates people to use this system? What does it enable people to accomplish? What need does the system fill?
Benefits of Storyboarding Holistic focus: helps emphasize how an interface accomplishes a task Avoids commitment to a particular user interface (no button yet) Helps get all the stakeholders on the same page in terms of the goal Better in team work (have time limits – 10min)
Paper Prototyping Tips & Tricks Keep all your materials in one place Work quickly & make reusable components (buttons, etc) If difficult to simulate, verbally describe the interaction Backgrounds (11” x 14” poster board) can be useful Don’t be afraid to mix & match h/w and s/w.
Get Creative with Materials Widgets : Paper, Cardboard, Transparencies Connectors : Tape, Glue, Rubber cement Drawing : Pens, Pencils, Markers … and more
Digital Mock-ups Wizard-of-Oz Prototyping Simulates machine behavior with human operators Make an interactive application without (much) code Get feedback from users people
The Wizard of Oz Technique A lot of critique feedback from the users when low quality/fidelity Requires some kind of interface Very useful to mimic some kind of AI in a cheap & quick way Help the design understand the logic of his application
Video Prototyping Benefits Cheap & fast Great communication tools Can serve as a ‘spec’ for developers Ties interface designs to tasks
What should the video show? Like a storyboard, the whole task including motivation & success Draw on tasks you’ve observed Illustrate important tasks your system enables Can help scope a minimum-viable-product Change what design teams argue about (in a good way)
What are the steps? Like anything, start with an outline (or your storyboards) Fine to extemporize Equipment (camera, people, location ..) In general, focus on message more than production values
Considerations Can use audio or silent movie with title cards (audio can be finicky) Interface can be paper, mock-ups, code, or invisible (just showing the task) Can show both success & failure (of your interfaces & others) Edit as little as possible because editing is hugely time-consuming (In-camera/pause editing is most efficient)
Creating & Comparing Alternatives Quantity vs. Quality (better) Parallel prototyping yields to more diverse designs In early stages of the design process, you should rather use parallel prototyping that serial prototyping
