Studies of robots which aim to entertain and to be conversational partners of the live-alone become very important. The robots are classified into DBC Dialogue-Based Communication robots and TBC Touch-Based Communication robots. DBC robots have an effect to be conversational partners. A typical application of TBC robots is Paro a baby harp seal robot which has an effect to entertain humans. The combination of DBC and TBC will be able to achieve both a conversational ability and an entertaining effect, but there is no study of combination of DBC and TBC. This paper proposes a response algorithm that can combine conversational information and touch information from humans. Criterions for estimation are defined as follows: FFV Familiarity Factor Value, EFV Enjoyment Factor Value, CR Concentration Rate, ER Expression Rate, and RR Recognition Rate. FFV and EFV are total ratings for questionnaire related to familiarity and enjoyment factors, respectively. CR measures attention for humans. ER is the interest of communication with robots by representing Level 2 laugh with opening one’s mouse, Level 1 smile, and Level 0 expressionless. RR is recognition ability for voices and touch actions. From the experiment for impressions of robot responses with 11 subjects, it turns out that the proposed method with combination of DBC and TBC is improved by 20.7 points in FFV, and by 12.6 points in EFV compared to only TBC. From the robot communication experiment, it turns out that the proposed method is improved by 8 points in the ER, by 5.3 points in the ER with Level 2, and by 24.5 points in the RR compared to only DBC.
