Abstract: The human-computer interaction community has evolved from using body-sensing to body-actuating technologies, transforming the body's role from a mere input to an input-output medium. With body-sensing, the separation between the human and the computer is clear, allowing an easy understanding of who is in control. However, with body-actuating technologies, this separation diminishes. These technologies integrate more closely with our bodies, where both the user and the technology share control over their bodily interactions. In this workshop, we will explore this notion of sharing control, specifically focusing on experiences where users interact with their own bodies (intra-corporeal experiences), and interact with others using technology (inter-corporeal experiences). Our discussions and group activities will focus on brainstorming and designing within human augmentation, examining how this shared control can lead to innovative applications.
