Managing Disorientation of Time and Place in Dementia Patients Using Bluetooth Sensors

Assistive technology has the potential to support persons with dementia (PWDs) in their daily life activitiesand provide them quality of life services. This paper proposes a novel mechanism in order to manage disorientationor time and place problem of PWD through the use of Bluetooth low energy devices, smart watch and smart phone/tablet. The proposed mechanism was verified in a real environment having the facilities an ordinary PWD avail in hishome environment and also in lab environment. All of the participants were volunteers from research group personalcontacts. Volunteers spend time in the environment and results were generated. Experimental result showed that theproposed mechanism provided an accurate real time ubiquitous monitoring of PWD. Successful detection of PWDpresence in real time and notification to caregiver observed in all cases.
