Relation between impression of touch panels' coloration and operation

Abstract

The relationships between the coloration used in designs of a touch panel and operation on electronic devices are discussed. Experiments that investigate the effect of color in designs of touch panel interfaces on the operation and on impressions of users have been conducted. Subjects tried mental arithmetic tests on twelve screens which are identified different color images. The following points: "time which passed during a task," and "number of correct answers," are measured and counted. After the tasks were administered, the subjects answered questionnaires about their impression of "preference" of the displays' color design. The results were analyzed from a viewpoint of the luminosity of the coloration which was used for the interface. As a result, the average of "number of correct answers" and "evaluation of preference" were higher when the differences of luminosity among colors used in the interface was small. Furthermore, the average of time which passed during a task was tend to be shorter in the situation. The result of the study lead us to expect that usability, accuracy and amenity of operations will be improved by considering the luminosity among colorations used for the touch panel interface.
