Conveying mood and emotion in instant messaging by using a two-dimensional model for affective states

We discuss the development and initial experiences with an instant messaging (IM) system that has been enhanced with functionality that facilitates the expression of affective states. This functionality is based on: (1) the use of a graphical, twodimensional base model developed by psychology researchers; (2)refinements of the base model to allow for increased precision in the expression of affective states while exchanging messages; and (3) the definition of meaningful icons associated with the aforementioned model. Experiments have been conducted which show that users are able to take advantage of the proposed IM enhancements when trying to convey affect.
