Personal emergency response (PER) system
A system includes one or more sensors to detect activities of a mobile object; and a processor coupled to the sensor and the wireless transceiver to classify sequences of motions into groups of similar postures each represented by a model and to apply the models to identify an activity of the object.
1. A wearable monitoring apparatus, comprising:
a housing adapted to be worn by a person on a wrist of the person;
an accelerometer disposed in the housing;
a processor disposed in the housing;
a user input device disposed on the housing;
wherein the user input device is adapted for selecting a predefined exercise,
and wherein the processor computes activity data for the selected predefined exercise based on signals from the accelerometer.
