Engaging Older People With Participatory Design

We present a design case focusing on participatory design (PD) with older people. We experimented with PD techniques to foster engagement with participants in development of a graphical user interface (GUI) for controlling a robotic system in a smart home environment. The tenet of our approach is that to engage older people in the design of future systems, it is of paramount importance to increment and reinforce knowledge using different techniques and materials, and to create an empathic and trusted relationship between participants and designers. We experimented with different techniques for achieving this, from video-based scenario evaluation to hands-on and gaming activity in which participants had to evaluate the dynamics of a context-dependent interface using an expression-rich modality of interaction. This permitted exploration of experiential elements of design, to reduce the need for the participants to engage in abstract thought and to collect insights on design solutions while having fun together. The entire procedure implied incremental PD cycles in which knowledge was shared and consolidated through a learning process based on doing and playing together. The final reflections highlight a number of recommendations that demand consideration when undertaking research and design work with older people.
