Abstract
Presented is a system and method for monitoring activities of daily living, ADLs, of a person within an environment. The system comprises an ADL inference unit adapted to receive a sensor output signal representative of a detected value of a property of at least one of: the person; and the environment, and to generate an inferred ADL output signal representative of the inferred ADL of the person. A monitor unit is adapted to generate a monitor signal dependent on at least one of: the received sensor output signal; and the inferred ADL output signal.
Claims15
A system for monitoring activities of daily living, ADLs, of a person within an environment, the system comprising:
- an ADL inference unit adapted to receive a sensor output signal representative of a detected value of a property of at least one of:
- the person;
- and the environment, and to generate an inferred ADL output signal representative of an inferred ADL of the person;
- and
- a monitor unit adapted to generate a monitor signal dependent on at least one of:
- the received sensor output signal;
- and the inferred ADL output signal,
- wherein the ADL inference unit comprises:
- a first inference subsystem adapted to receive the sensor output signal, to infer a primitive ADL event based on the received sensor output signal, the primitive ADL event being an event directly inferable from at least one sensor output signal, and to generate a primitive ADL signal representative of the inferred primitive ADL event;
- and
- a second inference subsystem adapted to receive the primitive ADL signal, to infer an aggregate ADL event from the received primitive ADL signal, the aggregate ADL event being an event based on at least one primitive ADL event, and to generate an aggregate ADL signal representative of the inferred aggregate ADL event, and wherein ADL inference unit is adapted to generate the inferred ADL output signal based on the primitive ADL signal and the aggregate ADL signal.
A method for monitoring activities of daily living, ADLs, of a person within an environment, the method comprising:
- inferring an ADL of the person based on a sensor output signal representative of a detected value of a property of at least one of:
- the person;
- and the environment;
- generating an inferred ADL output signal representative of the inferred ADL of the person;
- and
- generating a monitor signal dependent on at least one of:
- the sensor output signal;
- and the inferred ADL output signal,
- wherein the step of inferring an ADL comprises:
- inferring a primitive ADL event based on the sensor output signal, the primitive ADL event being an event directly inferable from at least one sensor output signal;
- generating a primitive ADL signal representative of the inferred primitive ADL event;
- inferring an aggregate ADL event from the primitive ADL signal, the aggregate ADL event being an event based on at least one primitive ADL event;
- and
- generating an aggregate ADL signal representative of the inferred aggregate ADL event,
- and wherein the step of generating an inferred ADL output signal ADL is based on the primitive ADL signal and the aggregate ADL signal.
