an approach for graphically visualizing the affective structure of a text document. a document is analyzed using a unique textual affect sensing engine. colors are used to represent different emotions in a color bar, which represents the progression of affect through a text document. an emoticon corresponding to the emotion depicted by that color is included to help reinforce the meaning of that color. a user evaluation demonstrates that the method facilitates a user’s within-document information foraging activity.
