21-6 An Evaluation of Prototyped Remote for Digital Broadcasting Receivers by Semantic Differential Method

Abstract

We conducted experiments to evaluate our prototyped remote for digital broadcasting receivers using the semantic differential method. Two major components - "General evaluation" and "Design" are extracted by the result of the principal component analysis. We find that there are significant differences in the each component score between the prototyped remote and the conventional remote that has many buttons. The result shows the effectiveness of our design processes to develop an easy-to-use remote.
