Dementia and Mobility
About 23 million people worldwide have some
form of dementia
Rate rises with age – 1.5% among people aged
65-69; 25% among people aged 85+
“The white epidemic”
Rate is expected to double every 20 years
Many people with dementia have problems with
mobility, especially outside the home.
Mobility problems, especially wandering, is one of
the main reasons for institutionalization of elders.

Spatial activity of visitors to (1) Theme Parks (Mini-Israel,
PortAventura - Catalunya) (2) Historic Cities (Akko,
Heidelberg) and (3) Multi-Functional Cities (Hong-Kong)

Recruitment of participants from three groups in each
country (Israel and Germany):
Healthy elders, Elders with Mild Cognitive Impairment (MCI),
Elders with Mild Dementia (MD)
Procedure repeated for three years.

•How do people move through space?
•What types of transportation do they use?
•Where do elderly people spend their time?
•How much of their time is spent at home?

Tracking people involves a lot of data
Tracking a person every 10 seconds means
collecting, storing and analyzing 360 points an
hour and 8640 points a day, 259200 a month...
That is a lot of data!
1. Using advanced tracking technologies opens up new
possibilities for empirical research (in terms of the
accuracy, and the data resolution).
2. The fact that the data is collected by digital interfaces allow
accelerated analysis (almost in real time) and in lower
3. Our research design enables us to link between the
geographical, medical and psycho-social data.
4. Possibilities to implement the methodologies to advance
research in other cases of pedestrian behavior.
