Project – Part 4

You will perform usability testing on your prototype for your alternative communications device.

Devise usability test questions and tasks which test all five usability characteristics:

Characteristic	Type of Usability Evaluation
Efficient	Time (or count clicks or page views) realistic tasks. Must use working versions of the software and plausible sample data.
Effective	Evaluate tasks for how accurately they were completed, and how often they produce errors.
Engaging	User satisfaction surveys or qualitative interviews can gauge user acceptance and attitudes towards the software.
Error Tolerant	Include task scenarios with potential problems in test use scenarios
Easy to Learn	Control how much instruction is given to test participants, or carefully recruit users with different levels of domain knowledge and experience.

Conduct the usability tests using either classmates or friends with the SnagIt software.

Your write-up for this project should include information about what tests you conducted, the information you received from those tests, and the changes that should be implemented to your prototype as a result.  (The actual changes will be made for your final version in part 5 of the project).
