Abstract
For the purpose of developing formative experience design methods, we conduct two proving field tests in the development of mixed media services. From these experiments, we propose the experience design evaluation format and formative evaluation process. This format is composed of “intent formation”, “experience description”, “reflection”. This format provided the perspective of observation and levelized descriptions. In a workshop of evaluation process, we shared and discuss our experience based on descriptions. This led finding issues and next challenge of service design based on reality.
