Information processing system, information processing terminal and information processing method

The invention relates to an information processing system and an information processing method, and aims at analyzing the operation of an operator by describing the action track of the operator. In a track describing device, after a user selects a tracking object region on a frame displayed by a display (500), an information obtaining part (352) is set to obtain the tracking object information in the region, and the tracking object information is preserved to a tracking object information storing part (354). After that, a tracking object tracking part (353) tracks the tracking object in dependence on the obtained tracking object information and a probability distribution image generated in a specified tracking method, and the tracking result data is preserved to a tracking result data storing part (356). After that, for each frame, a figure generating part (359) associates the frame of the preserved tracking result data with color information, and connecting the central coordinate of the frame which on a prev
