• Electroencephalogram Steady State Response Sonification Focused on the Spatial and Temporal Properties 

      Kaniwa, Teruaki; Terasawa, Hiroko; Matsubara, Masaki; Makino, Shoji; Rutkowski, Thomas M. (Georgia Institute of TechnologyInternational Community for Auditory Display, 2014-06)
      This paper describes a sonification approach of multichannel electroencephalogram (EEG) steady-state responses (SSR). The main purpose of this study is to investigate the possibility of sonification as an analytic tool ...
    • Guiding auditory attention toward the subtle components in electrocardiography sonification 

      Terasawa, Hiroko; Morimoto, Yota; Matsubara, Masaki; Sato, Akira; Ohara, Makoto; Kawarasaki, Masatoshi (Georgia Institute of TechnologyUniversity of Music and Performing Arts Graz. Institute of Electronic Music and Acoustics, 2015-07)
      ECG (electrocardiography) consists of a few components and features that indicate the details of electrical conduction in each part of the heart. The simple pitch-mapping sonification of ECG cannot indicate these components ...
    • Perceptual distance in timbre space 

      Terasawa, Hiroko; Slaney, Malcolm; Berger, Jonathan (Georgia Institute of TechnologyInternational Community on Auditory Display, 2005-07)
      This paper describes a perceptual space for timbre, defines an ob- jective metric that takes into account perceptual orthogonality, and measures the quality of timbre interpolation applicable to percep- tually valid timbral ...
    • Real-time smile sonification using surface EMG signal and the evaluation of its usability 

      Nakayama, Yuki; Takano, Yuji; Matsubara, Masaki; Suzuki, Kenji; Terasawa, Hiroko (Georgia Institute of TechnologyUniversity of Music and Performing Arts Graz. Institute of Electronic Music and Acoustics, 2015-07)
      We propose a real-time, interactive system for smile recognition and sonification using surface electromyography (EMG) signals. When a user smiles, a sound is played. The surface EMG signal is mapped to pitch using a ...
    • Sonifying ECoG seizure data with overtone mapping: a strategy for creating auditory gestalt from correlated multichannel data 

      Terasawa, Hiroko; Parvizi, Josef; Chafe, Chris (Georgia Institute of Technology, 2012-06)
      This paper introduces a mapping method, harmonic mapping, which projects multichannel time-series data onto a harmonic series structure. Because of the common fate effect of gestalt principle, correlated signals are perceived ...
