People naturally express frustration through the use of their motor skills. The purpose of the Affective Tangibles project is to develop physical objects that can be grasped, squeezed, thrown, or otherwise manipulated via a natural display of affect. Constructed tangibles include a PressureMouse, affective pinwheels that are mapped to skin conductance, and a voodoo doll that can be shaken to express frustration. We have found that people often increase the intensity of muscle movements when experiencing frustrating interactions.
