Abstract
In general, the methods for measuring human emotion are divided in two, one is the psychological way based on user's subjective evaluation and the other is the physiological way based on physiological signals. However, these methods have some limitations. Therefore, in this study we suggested the methods for measuring user's emotion in the natural and accessible environment for the design field. In order to observe user's emotional changes while they interact with a product, we have extracted some emotional words and representative emotions, and made a set of subjective evaluation scales. With these scales, emotion logging program “Video TAME”was developed as an effective measurement tool for complementing the current psychological methods. In the Testing Module of VideoTAME, subjects evaluate their emotional changes through playing and watching the video clips of their performing tasks in the experiment room. In the Analyzing Module, the researchers replay the results created by subjects during the experiment and analyze the results using Microsoft Excel. It is hoped that this study will be of great help for designers for effective measurement of user's emotions naturally expressed while using a product.
