This paper presents the concept of Lab-Forming Fields (LFF) and Field-Forming Labs (FFL). LFF is to transform real service fields into lab-like places for bringing research methodologies in laboratories to real fields with IoT. FFL is to transform laboratories into real-field-like places for getting subjects’ behavior and experimental results closer and closer to the ones which are supposed to be obtained in the real service fields with VR. In addition, this paper provides a summary table of previously conducted researches in AIST on LFF and FFL with geospatial computing.
