2
Usability and Interaction • Interface design in a virtual world
– Presence– Environment– Tools– Collaboration– Interaction– Project creation– Usability testing– Assessment
3
The authors learn to build and texture their class projects
Early Skill Development
4
A self-guided tutorial for building a 20-minute project
Modeling in Second Life
5
Using Second Life for UI Design• Self image
• Social networks
• Mentor, feedback
• Class projects
• Roleplay
• Tool integration
• Immersive design
• Build simulations
• Empirical testing
• Sense of presence
• Attend classes, collaborate
• Office hours, facilitation
• Applied learning activities
• Immersive learning
• MSN Live Meeting, phones
• Inside the organism
• Create prototypes
• Observe user behavior
80% of the world’s Internet users will be in a virtual world by 2011 (Gartner, 2007)
6
CS 820 Win 08 Class Projects
Newsstand, Electronic Voting Machine, Refrigerator
7
Design for Accessibility
• For vision and mobility impaired users
• Asynchronous and synchronous design activities
• 3D graphics, sounds, gestures and interaction
• Models, textures, sounds, animations, scripts
• Focus on user characteristics and task performance
• Collaboration in class and among students
8
Students new to a virtual world create low fidelity interface designs
and conduct usability tests in a virtual world
9
Interaction and Empirical Testing• Observed behavior
– Test plan– Test procedure– Roles– Volunteers– Observation– Measurements– Analysis– Results
Interface with rezzable objects
10
Conducting usability tests of the accessibility projects
Evaluating Interface Prototypes
11
Tasks and Skills Required
• Appearance– 1st self or ideal self?
• Move and look – Arrow keys or Navigation
menu
– Camera controls
• Communication– Voice, text, gestures
• Group Notices, IMs
12
Project Prototypes
Newsstand for the lowvision users; selecting
option 4 to hear
Refrigerator for wheelchair users;
shelves move out and down
13
Behavior and Task Performance
Studying interfaces from a wheelchair Testing the Electronic
Voting Machine interface
14Student projects on display at the TCC Online Worldwide Conference
15
Experimental Design Space
Fanciful classrooms created by a powerful simulation tool
16
Virtual Office Hours
Rather than view the tank in the office, get inside. The water’s fine!
