Abstract: Usability is an important step in the software and product design 
cycle. There are a number of methodologies such as talk aloud protocol, and 
cognitive walkthrough that can be employed in usability evaluations. 
However, many of these methods are not designed to include users with 
disabilities. Legislation and good design practice should provide incentives 
for researchers in this field to consider more inclusive methodologies. We 
carried out two studies to explore the viability of collecting gestural 
protocols from sign language users who are deaf using the think aloud 
protocol (TAP) method. Results of our studies support the viability of 
gestural TAP as a usability evaluation method and provide additional 
evidence that the cognitive systems used to produce successful verbal 
protocols in people who are hearing seem to work similarly in people who 
speak with gestures. The challenges for adapting the TAP method for gestural 
language relate to how the data was collected and not to the data or its 
analysis.
