The Dynamic Emotion Wheel (DEW) is a web application allowing users to report and share their emotions during a computer-mediated task.

• Inspired by the Geneva Emotion Wheel, the tool combines the two most widely adopted approaches to emotion self-report: the dimensional and discrete emotions approaches.
• Rooted in the Component Process Model theoretical framework, the tool adopts appraisal criteria and subjective feeling both for self-assessment and data visualization.
• Appraisal and subjective feelings are directly linked: the tool computes a subset of "most likely" discrete emotions according to a quantitative evaluation on two-dimensional criteria (e.g. Valence and Control/Power).
• Participants to a collaborative task can follow both their own and their partner's evolution of emotional episodes over time (awareness).
• The tool is meant to be flexible and extensible to different experimental contexts and applications.

A prototype of the tool has been at first developed as part of the Emotion Awareness Tools for Mediated Interaction (EATMINT) project, whose aims included the development of emotion awareness tools (EAT) to improve the collaborative processes and outcomes of people working together through computers.

The DEW is currently maintained by Mattia A. Fritz at TECFA, Geneva University, as part of his PhD thesis directed by Prof. Mireille Bétrancourt.
