Class 2: Evaluation Basics

I. Reality check: User Experience

What is the overall user experience when looked at:

• Desirability: does the user want to engage fully or wants to try the experience again?

• Satisfactory: is the user moving through the experience in a pleasurable way, with focus until the end?

• Usability: is the experience understandable to the user, are there any faults or delays in the interaction?

• Utility: is the product useful to the user and does it have a purpose that the user accepts?

• Efficiency: can the user learn quickly, is it fast to use?

• Effective: does it work, can I do it, does it do the job well?

• Safety: is it safe for the user to use? does the user feel safe in the experience? (physical and emotionally safe(!)

Tools: User Journey - Touchpoints - Proxemic areas - Action spaces - Rapid Prototype - Play-acting & User Testing

II. Reality check: Spatial Representation

1. Form Notion: what kind of form does the space have? You can use daily metaphors (closed): house, hut, nest, shell, cellar, shelter, temple, church, train, football field, dessert, forrest, laboratory, forest, laboratory, football field. Use daily metaphors (open-ended): infinity room, race track, beach, mountain, desert.

3. Rhythm of the Air: imagine the wind blowing through space. What does this space do? Does it: collide? explode? shatter? fragment? abstract? distort? and deform? fold? twist? erode? melt? float? climb? walk? dive?

USER TASKS: checking its quality

A Taxonomy of Usability Characteristics in Virtual Environments, Joseph L. Gabbard (1997)

• Navigation & Wayfinding

• System Control

• Selection & Manipulation

• Feedback, Feedforward & Force feedback
