Locator is a demonstrator application of Personis.
Locator provides an interface which enables a community of people to locate other members
of the community.
To join the community, a user needs to register both themself and sensors that can
provide evidence about their location.
For example, a Bluetooth enabled phone can be registered.
Another class of sensor is an activity sensor that detects when a person's computer
is in use.
The underlying infrastructure for Locator is based on Personis, which models people, places and
devices. It makes use of a range of varyingly reliable evidence to reason about an individual's location.
As Locator has been in actual use of a long period of time, it has provided insights
into the way that people use and respond to such information about each other as well as
and people's attitudes to management of privacy.
