Abstract
This paper presents a smart nutrient service system, TOUCH Doctor, developed under living lab methodology. In addition to user-driven open innovation, the work conducted in this research was highly interdisciplinary, including the various contributions from professionals in technology, communication, and medicine. The development of this system not only depended on the work of engineering and medical experts, but also on the links between the product and its users and cooperating company. The final co-creative innovation, then, was realized through academic, business and industry contribution that could be applied to increase the feasibility of the human-centric service design innovations. Additionally, with collected open data, we also designed web service apps for usability tests to continually improve upon the service provided.
