Watching TV once encouraged generations of families and friends 11 to communicate and share empathy. However, the Internet is changing how we watch TV and reducing interaction, leading to problems such as lack of self-control and inadequate communication skills 17. To understand the conversations while watching TV, we design a scheme based on human conversational behavior 2, and then develop a prototype of TV-watching companion robot supported by the chatbot “KACTUS” 20. The robot generates a disclosure utterance (e.g., ”I like elephants”) with extracted keywords from the TV program in “TV-watching mode” and uses a cross-topic dialogue management method from “KACTUS” with question utterance to respond with rich conversations in ”Conversation mode”. The robot switches between these two modes at a preset ratio (TV-watching:3, Conversation:1) and behaves like a human enjoying TV-watching. The result of initial experiment shows that three groups of participants enjoyed talking with the robot and the question about their interests in the robot were rated 6.5 (7-levels: ascending from ”extremely disagree” to ”extremely agree”).
