AngryEmail? Emotion-based e-mail tool adaptation

Abstract

This paper presents AngryEmail, an e-mail tool that adapts its behavior according to the user emotional state. When a user finishes writing an e-mail and clicks the send button, the e-mail is automatically analyzed to get information about the emotions reflected on it, following a lexical-based approach. If a high level of anger is detected, then the e-mail program keeps the message unsent, waits for five minutes and, afterwards, notifies the user that the e-mail will be sent one minute later. This approach allows users to reconsider the convenience of sending certain e-mails when they are noticeably angry. This can be useful for all the people in general, but especially for those with cognitive limitations, for whom emotion control is harder. © 2012 Springer-Verlag.
