Suggestion of Methods for Understanding User's Emotional Changes While Using a Product

摘要

The aim of this research is to suggest a most effective method for measuring user's emotions expressed while using a product. This study developed a tool that effectively measures the user's emotions expressed while using a product and that can complement the limitations of the psychological measuring method. The developed emotion logging software named VideoTAME, basically asks the subject to watch a recorded video clip of the user performing a specific task and to examine the emotional changes that had occurred. And a physiological measurement method that measures the user's emotions expressed during product use with VideoTAME and that is easily accessible in the design field was suggested. By upgrading VideoTAME and overcoming its limitations as a psychological measurement method, and also by using the physiological measurement method mentioned this study to measure the user's emotional changes, the correlation between the product usability and the user's emotion will be able to be defined more clearly.
