This paper presents a novel method for classifying regions from human movements in service robots' working environments. The entire space is segmented subject to the class type according to the functionality or affordance of each place which accommodates a typical human behavior. This is achieved based on a grid map in two steps. First a probabilistic model is developed to capture human movements for each grid cell by using a non-ergodic HMM. Then the learned transition probabilities corresponding to these movements are used to cluster all cells by using the K-means algorithm. The knowledge of typical human movements for each location, represented by the prototypes from K-means and summarized in a ‘behavior-based map’, enables a robot to adjust the strategy of interacting with people according to where they are located, and thus greatly enhances its capability to assist people. The performance of the proposed classification method is demonstrated by experimental results from 8 hours of data that are collected in a kitchen environment. ; QC 20170202 ; STRANDS
