In recent years, affordances h~ve been hailed by the interaction design community as the key to solving usability problems. Most interpretations see affordances as 'inviting the user to the right action'. In this paper we argue that the essence of usability in electronic products lies not in communicating the necessary action and instead shift our attention to feedforward and inherent feedback. With feedforward we mean communication of the purpose of an action. This is essentially a matter of creating meaning and we discuss two approaches to do so. With inherent feedback we try to strengthen the coupling between the action and the feedback. The sensory richness and action potential of physical objects can act as carriers of meaning in interaction. We thus see tangible interaction as indispensable in realizing feedforward and inherent feedback. We illustrate our ideas with examples from our teaching and research.
