eMoto is a mobile service for sending affective messages to others. The mobile phone user inputs what they want to express emotionally through a range of affective gestures. This alters the background of the text message (SMS) to include a range of affective expressions that make use of colors, shapes and animations . The interaction with gestures and changes of the text message background interactively pulls the user into an embodied ‘affective loop’. The design builds on a Laban-analysis of shape and effort.
