CSUN: An accessible approach to usability testing

Elizabeth Neil
Web Content Manager
AFB

Use research: benchmark for effectiveness.

Remote usability testing helps recruit a good mix.

Define user group.
Is there special equipment required?
Access criterion is more important than disability in their experience is more a function access method than disability.

Sampling techniques:
Snowballing, find one person and then use their contacts.
Random sampling, good but more suited to a lager population.
Quota sampling, fill specific criteria until defined number is met.
Opportunity sampling, finding folks who are at particular place, like a conference. Might be biased.

Recruitment strategies:
Organizations
lists
personal connections
programs

Types of research
Focus groups: more informal; usually most useful as a starting place. What people think they need.

Card sorting: How people sort information. Provide cards and see how people sort them. May need to be done creatively for his to be accessible, ie with Braille or large print.

Prototyping: can be useful early.

Heuristic review: use preexisting standards. Don't reinvent the wheel.

User's experience interviews: what are the user's expectations based on design.

Quantitative testing: time spent on task, keystrokes, etc.

Benefits of remote testing: real world testing, reduces burden on the user.
