Projects

Auditory-Centered Vocal Feedback System Using Solmization for Training Absolute Pitch without GUI

HCI Research | Jun 2020 – Sep 2021 | First Author (INTERACT 2021) | Five members

Conventional absolute-pitch training tools rely primarily on visual displays such as tuners or piano-roll guides, even though listeners with absolute pitch typically perceive musical notes verbally as pitch syllables rather than visual symbols. We designed a GUI-free, auditory-centered training system that delivers real-time vocal solmization feedback as notes are played. In a controlled study with 10 participants without absolute pitch, vocal-solmization training improved pitch-identification accuracy by approximately 25% in six participants, whereas a baseline visual-feedback condition yielded no measurable gain.

ElectroMagnetic Guitar: Chord Playing Support System on Guitar by Electromagnets

HCI Research | Apr 2019 – Mar 2020 | First Author (IWAIT 2020, Best Paper Candidate) | Two members

Forming multi-finger chord shapes on a guitar fretboard presents a steep physical barrier for novice players. We developed ElectroMagnetic Guitar (EMG), retrofitting a classical guitar with a custom fretboard of individually addressable electromagnets that guide magnetized fingertip attachments toward target fret positions. Preliminary user evaluations demonstrated sufficient magnetic force to stabilize chord hand postures while clarifying force-density requirements for active finger guidance.

A Picking Interface Seamlessly Connecting Passive and Active Performance on Guitar

HCI Research | Apr 2019 – Mar 2020 | First Author (IWAIT 2020) | Two members

Controlling live visual effects or audio parameters during guitar performance typically requires foot pedals or auxiliary controllers that interrupt natural playing posture. We engineered a sensor-augmented guitar pick that classifies three playing states — chord strumming, single-note picking, and non-picking — in real time from grip pressure and index-finger rotation angle, enabling performers to trigger multimedia effects seamlessly within their natural picking motion with high classification accuracy.

Shokyu

EdTech Project | Dec 2020 – Mar 2022 | Project Lead | Three members

Learners outside Japan rarely have access to authentic Shodo (Japanese calligraphy) instruction from certified instructors or to traditional calligraphy implements. Initiated during graduate school, Shokyu connected international learners with Japanese calligraphy instructors online and directly informed subsequent master's thesis research on automated calligraphy stroke critique. Awarded Second Prize (300,000 JPY) at the North Japan Bank New Business Competition.

Momentary English

Web Application (Personal Project) | Dec 2020 | Creator

Learners with solid English reading comprehension often struggle with real-time spoken fluency due to slow sentence formulation. Inspired by flash mental arithmetic drills, Momentary English is a lightweight browser-based training application that prompts timed Japanese-to-English sentence composition to build rapid spoken recall across desktop and mobile devices.
