Implementation and evaluation of a mobile augmented reality system for building maintenance

We implemented a mobile AR system for building maintenance workers based on participatory design of the system requirements. The technical implementation relies on hybrid tracking, combining computer vision tools, sensors and indoors locationing. The application was tested in a pilot case by end-users in field tests, where the users were able to evaluate the system that had been developed based on their own specifications. The results indicate good user acceptance and strong potential for utilizing BIM data and mobile AR solutions in building maintenance work, as well as for other building life cycle applications
