Abstract
A facility maintenance support system featuring annotation interpretation in addition to digital pen and paper-digital document management technologies is proposed. Handwritten annotation consists of character strings and drawings like lead lines. Annotation interpretation extracts information about which part of the facility, and when the maintenance worker's insights are described from the handwritten annotation on the maintenance sheet. The annotated facility is estimated by using printed object information provided from paper-digital document management. Time stamp of annotation is acquired from digital pen. Based on the interpretation, character string images are organized in time series manner by part of the facility, and are presented to the maintenance workers both on the monitor in the office and on the maintenance sheet in the field. Proposed facility maintenance support system was applied to the maintenance work for the wastewater plant in our research laboratory. The field trial reveals that sharing knowledge on the maintenance workers' insights can improve efficiency and reliability of the maintenance work based on the interview to the maintenance workers.
