20. User testing
“Real user testing”
• 5users
• Real users
• Real tasks
• 85 % of the usability hits
• Recording & logging of all user
reactions and feedback

53. Exercise
• Design a paper prototype
• Based on a persona characteristic
• To do:
§ Design paper prototype
§ User test
§ Adapt prototype, based on user test
54. Paper prototyping
• What?
– Interactive, visual representation of the user
interaction
– Material = paper
– Interactive prototype
• Contains: information, interactions, visuals, content,...
• The system‘works’
– Simulate interactivity
– Facilitator is ‘the computer’
– Scenario: functionalities of system
• Facilitator does not explain the interface (↔ storyboard)
55. Paper prototyping
• Why?
– Fast
– Low cost
– Interactive
– Lots of feedback
– Adapt easily
– No program skills needed

61. Timing
Groups
§ 3 persons
• usertests: rolls
§ Facilitator (“de computer”)
§ Observator
§ End user
• Time
§ 40 à 50 min: Paper prototype
§ 5 à 10 min Prepare test
§ 5 à 10 min Usertest
62. Background information
• Redesign the application to the different
functionalities
• Focus on the target group
– Make a list of properties, needs and wishes
66. 1. Design paper prototype
1. Add info to the persona
2. Make a list of the User Interface
elements
3. Make every User Interface element
§ Different screens
§ UI elements
4. Think of 5 tasks a user can do with your
application. Try to make a workflow.
67. 2.User tests
1. 3 rolls
1. Facilitator (“ be the computer “)
2. Observator (Intro, give tasks, note)
3. End user
2. Test
§ User: try to ‘think aloud’ & try to empathize in
the persona
§ Facilitator: make the interaction as smooth as
possible
§ Observator: Always try to ask why a user does
certain actions. Your user is always right.
