公共空間3箇所で運用した人型ロボットヘッドの受容性に関するケーススタディ
A Case Study on the Acceptance of a Humanoid Robotic Head Employed in Three Public Spaces
感情表現を伴う多言語対話が可能な人型ロボットヘッドを3つの公共空間で数日間運用し、TAM2アンケートで受容性を評価。観光案内所や図書館では好意的に受け入れられたが、オフィス環境では対話意欲が低く、応答速度の改善が課題と判明した。

Previous research has shown that a human-like robot's acceptance heavily depends on the setting in which it operates and its ability to perform relevant tasks. This paper, first, reports on how our robot processes natural language to generate a multimodal, verbal response integrating emotional expressions based on an emotion simulation backend. Then, it describes how visitors were invited to speak with our robot in their own language at three different, public locations, where the robot was running continuously for several days. The TAM2 questionnaire results reveal that on average users were motivated to use the robot and found it rather useful and easy to use regardless of the specific location. However, public spaces like the tourist information and the city library seem to be a better fit for our interactive, robotic head than an office environment such as the building authority, where the willingness to interact was lower. Overall, the robot's multi-lingual responses were very much appreciated, but every fifth user found the response time too slow impeding the dialog flow, which remains to be improved in future work.
