About
Mariko Chiba is a leading researcher in human-robot interaction, specializing in socially assistive robotics for elderly care. Her work addresses the critical challenge of combating social isolation among older adults by developing dialogue systems that can sustain long, meaningful conversations. Chiba's most significant contribution is the innovative "twin-robot" concept—a dialogue system using two physically embodied robots that actively listen and converse with each other and the user. This design overcomes a key limitation in the field: the fragility of speech recognition with elderly users, whose speech patterns can be less predictable. By having the twin robots maintain a dialogue even when speech recognition fails, her system ensures continuous, engaging interaction. Her seminal 2020 paper on this topic has garnered 46 citations, while her 2021 study on the effects of multiple conversation robots, with 33 citations, provides empirical evidence that such systems can significantly extend conversation duration in care homes. Chiba's work is notable for its practical, user-centered approach, moving beyond simple question-answer bots to create a more natural, resilient conversational partner. Her research is paving the way for robots that can offer genuine, sustained mental and social support to an aging population.
