Rapid evaluation of TV interaction devices using a Cognitive Walkthrough method

Abstract: Efficient methods for rapid evaluation of television (TV) interaction devices are missing. This thesis presents how the Cognitive Walkthrough method can be modified to suit the demands of engineers in a development process. Moreover, the thesis also investigates how Personas can be applied to support the Cognitive Walkthrough method. The Modified Cognitive Walkthrough method was applied and tested in an actual development project on remote control design. The study suggests that the method can detect usability problems on TV interaction devices at an early stage of development. Further, the results indicate that it is easy to understand the method and apply it as part of the engineering practices.
