  Falling continues to be a significant risk factor for older adults and other
mobility limited individuals. Monitoring and maintaining clear, tripping hazard
free pathways in living spaces is invaluable in helping people live
independently and safely in their home. This paper proposes and demonstrates a
Microsoft HoloLens-based technology for monitoring the open walking areas in
living spaces. The system is based on the 3D mesh produced by the HoloLens
augmented reality device. Several algorithms were implemented and evaluated to
handle the noisy raw mesh to help identify all possible floor spaces. The
resulting 3D model of the home was then processed to find United States
Occupational Safety and Health Administration (OSHA) approved pathways through
the homes. The long term goals of these technologies are to monitor the living
spaces clutter and clear walkways over time. The information it generates shall
be provided to the residents and their caregivers during environmental home
assessments. It will inform them about how well the home is being maintained so
proactive interventions may be taken before a fall occurs.
