A model-driven approach for prospective ergonomics: Application to ikigai robotics

Prospective Ergonomics requires building a vision of the future, which can be achieved empirically (e.g. analysing unmet needs) and/or creatively (e.g. creating future needs). We develop an
alternative way of imagining the future, through a model-driven approach. Based on several developmental models, we provide a global picture of possible future(s) emphasising higher-ordered motivations and values (e.g. meaningfulness, accomplishment). To implement them, we then present a model of human accomplishment reinterpreting the concept of ikigai in light of selected psychological theories (e.g. self-determination, eudaemonic well-being, mindfulness). Finally, we apply it to an Industry 5.0 case study named ikigai robotics: we designed an equipment for railway maintenance following a double design process – a functional design loop and a motivational design loop. The process proved inspirational and the results both original and promising, opening avenues for Prospective Ergonomics to develop a new approach for designing the future.
