Abstract

情報システムで利用される擬人化エージェントは,利用者との間に対人インタラクションを模したコミュニケーションをもたらし,高次の機器利用へつなぐ狙いがある。こうした相互作用においてエージェントに対する生物らしさ知覚が基盤になると考え,擬人化エージェントの生物らしさ知覚の有無と,そこでの身体性の効果を検討した。オーブンレンジを対象とし,目・腕のロボットパーツを取り付けた身体条件,音声だけの音声条件,エージェント化しない統制条件の3条件を比較した。65歳以上の高齢者と若年成人各36人がユーザビリティテスト形式の実験に参加し,主観的な生物らしさ知覚を評価した。その結果,生物らしさ知覚には"生体感"と"知性"の2側面があり,高齢者は身体性付与により両者が高まるが,若年者は特に"知性"に関し身体性の付与による評価の低下を示した。年齢群間での相違を基に,エージェントの生物らしさ知覚の機序について検討した。

Embodied agents quipped to the information systems make communication between users and agents more smoothly, which in turn lead users to more high order usage. We have a hypothesis that human-like interaction with agents may be based on user's perceptions of animacy to the agent. In order to investigate whether users perceiving animacy to the agents or not, and also to know how those animacy perception will be affected by the physical embodiment of agent, we executed an experiment to compare three agent conditions with a microwave oven: the embodied condition equipped with the antheropomorphization robots shaped eyes and arms, the voice_only condition equipped with the agent's voice, and the control condition without agent. Each of 36 participants who were older adults (aged over 65) and younger adults (undergrad students) executed the usability test of the oven and evaluated the subjective perceptions of its animacy. The result showed two type of animacy; lifelikeness and intelligence. Older adults showed increasing with both types of animacy when the agent had the embodiment, whereas younger adults decreased evaluation of intelligence with the physical embodiment. Based on the differences between two age groups, we would like to propose a model of agency, perception of animacy, and the base system.
