The method is illustrated by reference to the measurable changes in usability resulting from the continual development of television sets. The paper shall comprise three parts. First, a review of the information requirements for inclusive design, coupled with a review of the availability of user capability and anthropometric data. Second, a description of the development of a framework for usability evaluation. Finally, an evaluation of the new method by reference to its application to a redesign case study, that of television controls.
Televisions are commonplace within many households.
These changes have been accompanied by an ever- increasing number of channels and, in recent years, a move from set top controls to the use of remote controls for channel selection, volume control and a number of other features. The review, using the approach described above, shall compare the relative merits of typical examples of each control technology with a focus on the actions of switching the television on and selecting a channel.
