Environments

Usage of robot and sensor in every-day surrounding of elder people with dementia:

• nursing home
• day care
• at home

All these places are inside a building and known to the robot.
The Robot-Sensor construction might not be helpful in clinical surroundings, since the sensor at the door must be activated every time a person (doctor, nurse, family) leaves the room. 

The room or house has to have a door. That door leads outside the patient's room or outside the building, where the patient is not allowed to go (alone).
