This paper examines humans' cognitive characteristics toward home robots within the home environment over the course of a 16-day-long experiment. We applied protocol analysis to analyze user utterances recognized by a voice recognition system on the home robot. In this paper, time-series analysis has been conducted in order to investigate the change of cognitive characteristics toward the home robot over the passage of time. The results indicate that (a) users get accustomed over time to the robot and attachment emotions are elicited by living with the robot and (b) users gradually come to understand how the robot works and to construct a companion model for the robot as a sort of a mental model, which is an internal model for how something works.
