  1. Design and Prototyping CS 5115 Fall 2013 September 18

  2. Agenda for today • Project check-in • Due tomorrow • Design and Prototyping

  3. Paper (Low Fidelity) Prototypes • Sketches of interface and task completion • paper, post-its, or screen drawings

  6. LoFi pluses • Easy to produce • Rapid iteration / generate then test • To get a good idea, get lots of ideas • Never look for the “best way” – look for hundreds of ways • Users focus on the important stuff • Bugs don’t halt testing • Status is clear – proper expectations • Designers don’t get emotionally invested

  7. LoFi limits • Hard to capture timed, dynamic interaction

  8. What to prototype? • Screen layouts and information display • Work flow, task design • Technical issues • Difficult, controversial, critical areas

  9. Resources • Paper widgets you can download and print http://www.userfocus.co.uk/resources/prototype.html • Electronic tools • Balsamic: http://www.balsamiq.com/ • Pencil: http://pencil.evolus.vn/en-US/Home.aspx • Stencils available for Android 4.0 http://evoluspencil.googlecode.com/files/Android.GUI_v2.zip

  10. Prototyping Exercise

  11. Prototyping Exercise, 1 • Individually: sketch a campus kiosk system designed to help people find their way around the University of Minnesota campus. The kiosks will be located at a number of positions around campus.

  12. Prototyping Exercise, 2 • In groups of 3-4 • Review the individual prototypes • Pick a starting point for a second (revised) prototype • Draw a second prototype as a group

  13. Prototyping Exercise, 3 • Still in your group: select a task... • Find a building: get directions from current location to that building • Find a class: find the time and location of a class (for example, “User Interface Design” or “CS 5115”) • Find a person in the campus directory, get directions to their office And did you think about who your users were? Did you have an implicit persona in mind? • Evaluate how well your prototype supports that task • Redesign your prototype as necessary • (If necessary) redraw your prototype for presentation to the class

  14. Discussion • How much difference was there between the individual designs? • Did you think some were better than others? Why? • How much did the task focus help? Did considering a task make you change your design significantly? • How did you think about users and usage?
