A Novel Affective Design Tool: Task Emotion Analysis (TEA)

jats:p As research interests have been increased on emotions and affect in Human Factors and Human-Computer Interaction (HCI), extensive research has been conducted on developing emotion detection technologies. However, little research has been conducted on the necessary former steps–for example, identifying what emotions are involved in specific use cases and how those emotions need to be treated. The present paper introduces a novel affective design tool, “Task Emotion Analysis (TEA)” following the traditional Human Factors method, Task Analysis. TEA involves basic task analysis but provides (1) what types of emotions are induced from or engaged with each task, (2) why they are induced, and (3) how they can be mitigated through interactions with technologies. Sample TEA results are provided to demonstrate its effectiveness. We hope that TEA can provide a legitimate method for the design of empathic interfaces and contribute to conducting deeper emotion analysis in Human Factors and HCI research. </jats:p>
