Analysis of User Feelings during Interface Operation: Implictions for Creative Design
This research proposes a new approach for creative design based on comprehension of human feelings during user interface operation. The discussed method in this approach captures verbal input during interface operation through protocol analysis, and it identifies words and expressions which indicate the comfort of mind experienced by humans. Further, the method employs associative concept network analysis to identify the in-depth impressions, which are inexplicit indicators of comfort of mind, behind the verbalized words. In-depth impressions of subjects, identified during an experimental study in which they used operational devices in vehicles, indicate their level of comfort of mind with the product interface. Applying the proposed method, such impressions can be used further in the creative design of future products so that they will provide comfort of mind to users.
