This study aimed to clarify the changes in human life brought about by digital transformation (DX) through microscopic analysis. The data for this study were rehearsal data from a corporate training program. This program was originally conducted as a field trip to disaster-affected areas but was re-developed as an online trip due to the impact of the COVID-19 pandemic. We focused on the fact that the program provider repeatedly stated that “we want you to come to the field actually” to the program receivers in the opinion-exchange session. We could see these statements as certain procedures for providing accounts about the “lack of sufficiency” of online activity used by providers. In other words, regarding field as an idealized place, the providers dealt with the lack of sufficiency of online activity that the program receivers might feel. In this study, we call the field conceptualized by participants as “field as the home base”. Therefore, the concept emerges retrospectively against lack of sufficiency through interaction between participants. It is used in order to compensate for the lack of sufficiency of online activities. There are many benefits to the changes that DX has brought about in human life, but there are also negative reactions such as avoidance of DX and psychological barriers to it. The field as the home base can become a source of these negative reactions. If we are to further promote DX, it will be important to pay closer attention to the specifics of changes in human life.
