Event-Based Spatial-Carrier Interferometry for Surface-Normal Vibration-Waveform Reconstruction
Ryogo Niwa, Tatsuki Fushimi, Yoichi Ochiai
Non-contact measurement of small vibrations perpendicular to a surface supports the evaluation of mechanical structures, but in camera-based interferometry, increasing the frame ra…
Galvanic Vestibular Stimulation in Latent Space
Zhi Liu, Tatsuki Fushimi, Yoichi Ochiai
The paper presents a dataset linking galvanic vestibular stimulation (GVS) waveforms to free-form sensation descriptions and introduces a retrieval‑guided variational autoencoder t…
WhiteTesseract: Reframing the Interpretation of Cultural Heritage through XR and Conversational AI
Jingjing Li, Zhi Liu, Xiyao Jin +2
Cultural heritage exhibitions often struggle to sustain attention and support reflective engagement. Physical exhibitions rely on fixed interpretive aids that lack adaptability to…
Acoustic Manipulation of Tangible Janus Icons on Liquid Droplets
Yusuke Koroyasu, Yoichi Ochiai, Tatsuki Fushimi
Interfaces that couple digital information with physical matter enable computation to be expressed through tangible motion and touch, yet typically rely on embedded actuators, rigi…
Event Topology-based Visual Microphone for Amplitude and Frequency Reconstruction
Ryogo Niwa, Yoichi Ochiai, Tatsuki Fushimi
Accurate vibration measurement is vital for analyzing dynamic systems across science and engineering, yet noncontact methods often balance precision against practicality. Event cam…
Reversible vertical positioning of acoustically levitated particle using a spiral reflector
Yusuke Koroyasu, Takayuki Hoshi, Yoshiki Nagatani +3
Dynamic positioning in acoustic levitation typically depends on active control of the transducers phases, which necessitates complex driving electronics. While mechanically actuate…
