For evaluation of the three new prototype remote controls, we constructed a setting in which each person(persona) had the opportunity to use each controller for particular tasks. During these tasks, the person was encouraged to voice their thoughts as they performed actions. It was thought that such a process would reveal additional information about the cognitive processes employed by the subject as they experimented with each new controller and, in turn, highlight issues regarding the design. Additionally, the subject was encouraged to ask any questions they may have about the controller functions. Each subject was given the task of using the internet option (as in the former task analysis) and composing an e-mail. For the second task, the subject was informed that they must use both the keyboard and speech recognition facilities to complete the task. For this process we selected Derek, who had stated in his questionnaire responses that he found the controller to be cumbersome, and Rebecca, who had difficulty with every task during Task Analysis.
