Designing multi-touch gestures to support emotional expression in IM

The dramatically increasing use of IM and the lack of visual and aural nonverbal behaviors in this channel of communication have presented a variety of challenges and opportunities for researchers in the area of HCI and design. In this preliminary study, we, through design research, identified a group of text-based emotional cues users apply to express their emotions in IM and accordingly developed a set of multi-touch gestures to support emotional expression in IM communication.
