With new technologies such as body sensors, tangible interaction, haptics, interactive cloth, or small computing devices such as mobiles, we can move interaction from the desktop out into the world and onto our bodies. Likewise, with the boom of computer games, domestic digital technology use, and social communication tools, we have to consider designing for non-instrumental goals, beyond task completion. This has been picked up by human-computer interaction researchers in the so-called third wave of HCI. We suggest that learning technologies could use some of the results from the third wave of HCI, placing body and emotion more centrally into the communication and construction of knowledge. Designing for bodily interaction, emotional communication or aesthetics is not trivial. In design work, a designer can only set the stage for certain experience to happen, but in the end, it is the user who co-constructs the experience with or through the interaction. Based on our experiences of designing for bodily and emotional communication, we will posit three postulates that might be helpful in designing for involving interaction: leaving ‘surfaces’ open for users to appropriate, building for users to recognise themselves socially, emotional or bodily through the interface, and avoiding reductionism.
