1. A system, comprising:
- one or more wireless nodes forming a wireless network;
a user activity sensor including an accelerometer and a wireless transceiver adapted to communicate with the one or more wireless nodes using the wireless network; and
a processor analyzing accelerometer data and coupled to the wireless transceiver to request assistance from a third party based on the user activity sensor by distinguishing between falls and other types of normal body movement, the processor initiating a telephone call seeking assistance for the user if the user pushes a help button or if the processor detects a dangerous condition, and wherein sequences of human motions are classified into groups of similar postures represented by model-states with a posture model depicting inter-relationships among model-states.

19. A method to monitor a person, comprising:
-
capturing and transmitting the person'"'"'s daily activities over a wireless network; determining a pattern associated with the person'"'"'s daily activities using a statistical recognizer to distinguish between falls and other types of normal body movement, including extracting features from body signature sequences representing one or more motion types and matching a sequence of motions corresponding to the one or more motion types; and requesting assistance with a telephone call if the person'"'"'s current activity varies from the pattern or if a dangerous condition is detected or if the user manually requests assistance, and wherein sequences of human motions are classified into groups of similar postures represented by model-states with a posture model depicting inter-relationships among model-states. - View Dependent Claims (20)

21. A method to monitor a person, comprising:
-
capturing and transmitting the person'"'"'s daily activities over a wireless network; determining a pattern associated with the person'"'"'s daily activities using a statistical recognizer to distinguish between falls and other types of normal body movement; and requesting assistance if the person'"'"'s current activity varies from the pattern or if a dangerous condition is detected; and detecting a weakness in left half and right half of the person'"'"'s body;
a walking pattern for loss of balance or coordination;
requesting hands/feet movement in a predetermined pattern and reading accelerometer output in accordance with the predetermined pattern;
checking whether the person experienced dizziness or headache;
displaying a text image and asking the person to read back the text image one eye at a time;
using a speech recognizer to detect confusion, trouble speaking or understanding; and
/or asking the person if numbness is felt in the body.
