Opportunity Knocks: a System to Provide Cognitive Assistance with
Proceedings of UbiComp, 2004.
We present an automated transportation routing system, called ``Opportunity
Knocks," whose goal is to improve the efficiency, safety and independence of
individuals with mild cognitive disabilities. Our system is implemented on a
combination of a Bluetooth sensor beacon that broadcasts GPS data, a
GPRS-enabled cell-phone, and remote activity inference software. The system
uses a novel inference engine that does not require users to explicitly
provide information about the start or ending points of their journeys;
instead this information is learned from users' past behavior.
Futhermore, we demonstrate how route errors can
be detected and how the system helps to correct the errors with
real-time transit information.
In addition we present a novel solution to the problem of labeling
positions with place names.
