Robot design needs users: a co-design approach to HRI

The rapid technological growth that we are facing has highlighted issues about human-computer interaction, specifically with reference to the scope of robotics; this kind of dynamics open up new challenges for UX designers. We refer specifically to the category of social robots, which is a growing sector in the market of humanoid robots. Social robots must provide a good level of interaction with human beings, who interlace complex and deep relationship with them; they are able to learn from the environment in which they are located as from the interactions with users and to develop some sort of decision-making autonomy. Designing a social humanoid robot is not just the development of a consumer product as a household appliance and is not just the engineering of a body to a vocal assistance, but it also requires taking into account the psychological impact of the robot and evaluating social dynamics. Therefore, it is fundamental to place the individual at the center of the design process in order to study an acceptable user experience. Co-design methodologies are now considered an essential practice, especially in technological projects, due to the fact that a high-tech product, system or service is most likely capable to actively interact with users for which is intended. Designing an interactive and funny co-design experience is fundamental in order to positively engage users and get valuable data and insight about their perspective on the project that is being developed. Reflecting on the main themes and issues that must be taken into consideration in the design of a social robot based on UCD principles, the paper aims to propose new challenges and approaches for co-design activities for the robotic project, taking advantage of digital platforms and innovative IT solutions.
