For the purpose of achieving the effective and efficient human-centered design, a database of problem micro scenario (p-MS) is proposed. In the concept of this system, the human scientist work first for getting the information about the user and the context of use by applying the field work methods. The information about problems discovered in the field data will be stored in the p-MS database with the tag and the ground information. Engineers who plan to manufacture something can retrieve relevant problem information from this database, thus they can shorten the time required for the early stage of development. This idea of p-MS database is believed to facilitate the human-centered design and the feasibility study will be conducted within a year from this presentation.
