Abstract. We introduce the concept of identity-differentiating widgets (iDwidgets), widgets parameterized by the identity of their user. Although multi-user applications have become more common, most support only traditional “single-user ” widgets. By adding user-identity information we allow interactions with today’s widgets to be dynamically customized on a per-user basis in a group usage setting. The concept has inspired the design of new widgets as well. In this paper we describe example iDwidgets and define a conceptual framework based on what is being customized in the widget. iDwidgets can support novel interaction techniques in collaborative settings.
