About

Tomoaki Fujihara is a researcher whose work sits at the intersection of acoustic engineering and human-robot interaction, with a particular focus on enabling robots to operate effectively in real-world, noisy environments. His key research areas include microphone array design, sound source localization, and robust person-following algorithms. Fujihara’s most notable contribution is the design and implementation of a 32-channel omni-directional microphone array, detailed in his 2011 paper (13 citations). This work introduced a novel evaluation index based on the directional characteristics of delay-and-sum beamforming, allowing for the optimization of microphone arrangements to minimize sidelobes and improve spatial filtering. In earlier foundational work (2008, 4 citations), he investigated how humans modulate their speech loudness when interacting with robots in noisy settings, providing critical data for designing more intuitive voice interfaces. His 2009 paper (3 citations) demonstrated a robust person-following module for both indoor and outdoor environments, leveraging RT Middleware to validate distributed object technology in robotics. Through these contributions, Fujihara has advanced the practical deployment of robots that can hear, follow, and interact with humans amidst real-world acoustic clutter.
