SUBJECT SENSING IN AN ENVIRONMENT
First Claim
1. A method for subject sensing, comprising:
- generating a first layer of information associated with sensing of a subject, the first layer of information comprising presence information, counting information, and location information for a plurality of subjects in an environment, wherein the subject is contained in the plurality of subjects;
generating a second layer of information associated with sensing of the subject, the second layer of information comprising one or more of tracking information or identification information for at least one of the plurality of subjects; and
providing location information and identity information for the subject based at least on matching a portion of the first layer of information with a portion of the second layer of information.

Abstract
A multimodal sensor network is designed to extract a plurality of fundamental properties associated with subject sensing. In one aspect, such network can combine cameras distributed in an environment with inertial sensors available in subjects'"'"' wearable devices. The network can permit anonymous detection, counting, and localization of one or more subjects utilizing the cameras. In one aspect, by fusing such information with positional data from the inertial sensors contained or coupled to wearable devices associated with the one or more subjects, the network can track and can identify each subject carrying a wearable device functionally coupled to inertial sensor(s). In one aspect, the problem of subject sensing can be divided into two parts: (1) a detection, counting, and localization (DCL) layer and (2) a tracking and identification (TI) layer, wherein such layers can be implemented via simulations and a real sensor network deployment.

6. A method for subject sensing, comprising:
-
detecting a plurality of subjects moving in an environment by a first sensor; extracting first location information of a subject of the plurality of subjects based at least on the detecting action; receiving second location information of the subject from a second sensor; matching second location information of the subject with the first location information, thereby tracking the subject; and
, in response to the matching,assigning a subject location to the subject based on the first location information, and assigning a subject identity (ID) to the subject based on identifying information associated with the second sensor. - View Dependent Claims (7, 8, 9, 10, 11, 12)
