This study explores the factors that lead people to anthropomorphize robots by comparing different robotic devices and an interactive technology. It analyzed 750 online forum posts about the Roomba robotic vacuum cleaner, the AIBO robotic dog, and the iPad tablet computer. The research anticipated the highest level of anthropomorphism in posts about AIBO. Findings confirmed that people anthropomorphize their AIBO significantly more than their Roomba or iPad. Additionally, the topic of the forum post significantly influenced the use of anthropomorphic language.
