Qualitative Understanding of Viewers’ Needs related to the Design of TV Screens for Information Display

This study aimed to understand viewers’ needs regarding the design of TV screens for information display. An interview survey was conducted with 8 participants, using the evaluation grid method. An analysis of the higher-order items of the interview data in terms of the similarity of the contents revealed the interviewees’ needs of “acceptance of information,” “watching video content,” “selection and concentration of a video or information,” and “suppression of saliency in the information display area.” An analysis of the lower-order items of the interview data revealed the design elements related to these needs. Subsequently, a correspondence analysis was conducted between these needs and elements to consider the effective design elements to satisfy these needs. Based on these results, we discussed that viewers’ needs for the design of TV screens for information display are diverse, and that it is important to develop design guidelines considering such diversity.
