DESCRIPTION

Students and the instructor discuss the use of Second Life for prototyping and evaluating user interfaces in a CS 820 Usability and Interaction doctoral class. The projects featured accessibility projects, including a news stand for low vision users, a refrigerator for users in wheelchairs and an electronic voting machine. The students designed low fidelity prototypes, then conducted usability tests with subjects from class and from other schools. Presented at the CCSC Rocky Mountain Regional Conference 2008, October 17, 2008. Authors: Cynthia Calongne, Dawn Frankovich, Steven Endorf and Johnny Sandaire. See http://ctusoftware.blogspot.com for additional information.

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!
