ロボット発話時の感情に応じた振動触覚フィードバックシステム
An emotional expression system with vibrotactile feedback during the robot's speech
GPT-4o Miniでテキストの感情価と覚醒度を推定し、その値に応じて振動刺激の振幅と周波数を制御する掌サイズの触覚ディスプレイを開発し、ロボット発話時の触覚フィードバックが心理状態や親密さに与える影響を実験で示した。

This study aimed to develop a system that provides vibrotactile feedback corresponding to the emotional content of text when a communication robot speaks. We used OpenAI's "GPT-4o Mini" for emotion estimation, extracting valence and arousal values from the text. The amplitude and frequency of vibrotactile stimulation using sine waves were controlled on the basis of estimated emotional values. We assembled a palm-sized tactile display to present these vibrotactile stimuli. In the experiment, participants listened to the robot's speech while holding the device and then evaluated their psychological state. The results suggested that the communication accompanied by the vibrotactile feedback could influence psychological states and intimacy levels.
