This study shows that it is possible to use position information to estimate the volume of communication in offices to some degree based on (1) office position information from sensing technology and (2) data from daily questionnaires from a survey of 308 employees in a corporate office. The relationship between the office environment and communication has come to the fore in recent years, and the findings of this study suggest how communication within an office can be estimated for a large

... le at a low cost. the daily questionnaire are only subjective, so there may be problems with the accuracy of the responses. In summary, although there is some room for further consideration, because a positive correlation was seen, we proved that communication volume estimated from positional information has some degree of validity. Conclusion This study showed that communication estimated from position information from sensors in an office on the basis of certain criteria (jointly in a conference room or other area, or a total of 12 out of 30 seconds (40% of the time) within a 1.2 m distance) can be valid. If communication gathered from position information can be estimated to some degree, it will be possible to get an idea about office communication for a large sample at a low cost. Being able to do this would definitely be useful in research on organizational communication and research on social networks.
