Abstract:
A portable system carried by a user for assessing body movement, the system comprising:at least one motion sensor adjacent a portion of the user's body; an analog-to-digital converter connected to said at least one motion sensor for converting an analog signal thereform into a digital signal; a logic circuit connected to said analog-to-digital converter for calculating parameters based upon the digital signal; first fuzzy logic processing means connected to said logic circuit for processing the calculated parameters and for generating corresponding fuzzy classification labels based upon movement of the portion of the user's body during an interval of time; a memory connected to said first fuzzy logic processing means for storing at least one of the calculated parameters and the fuzzy classification labels; and second fuzzy logic processing means connected to said memory for generating an activity index representative of the movement of the user during the interval of time based upon the fuzzy classification labels.
