Color Application Analysis and Discussion of Portable Touch Device by Using Grey Relational Analysis

Through visions, colors could provide different feelings in mental and physiology way which would bring visual color preference and then influence consumer's purchasing and using desire. Owing to the prevalence of portable touch devices, such as tablet personal computer and smart phone and also the popularity of Internet and social networking service, the portable touch devices which equip independent operation system and could extend its functions by installing applied software and game programs have become consumer's major choice. However, current portable touch device develops its touching gestures, equipment efficiency and supporting software as mainly subjects. Most of the color of these devices is black or white and it seldom focus on consumer's perceptual needs. This study used Kansei engineering and semantic differential technique to do analysis and discussed consumer's color imagery and preference about portable touch devices. By using grey relational analysis to analyze the correlation between the color of portable touch device and expected texture. The result showed the ”black” sample in Kansei words closed to the expected imagery of smart phone from questionnaire takers. Hope it could be a reference for designers when allocating colors for color plan in their portable touch device.
