Walking reflects subtle signs of health.
Gait Analyzer Insight (G-AI) analyzes walking patterns in real time using AI-based image recognition,
simply by recording the person’s walk with the iPhone camera.

No special devices or markers are required.
Just capture the walking motion, and the results appear instantly on the spot.

G-AI brings a new, accessible tool for wellness, monitoring, research, and education.

🎯Key Features

• AI-powered gait analysis

AI, based on the Three-Dimensional Pose Tracker (TDPT) algorithm, analyzes walking footage directly on your iPhone.
It quantifies posture, stride, and rhythm in real time — making gait “visible” with no extra equipment or setup.

• Real-time feedback with zero wait

Analysis completes as you record — results are displayed immediately.

• Privacy-first design

All processing is completed securely within the device.
No images or recordings are uploaded or stored externally.
All gait data are analyzed locally in real time, ensuring complete privacy protection.

• Research-backed technology

Developed through joint research with Nagoya City University and based on peer-reviewed studies (Sensors, 2022, 2023; Yamada, Aoyagi et al.).
Built on the TDPT algorithm, the system quantifies gait characteristics such as shuffling, short-stepped, or wide-based walking by estimating joint angles and motion trajectories from 3D pose projections.
The technology has been presented at international and domestic conferences, including the International Society for Hydrocephalus and Cerebrospinal Fluid Disorders (2024, 2025), the Japanese Society of Normal Pressure Hydrocephalus (2021–2025), the Japanese Society for Medical and Biological Engineering (2023), and the Japan Society of Fall Prevention (2022, 2023, 2025).

• Supporting health and safety

Easily visualize subtle changes in gait.
Useful for raising daily health awareness and assisting in the early detection of fall risk.

❓Frequently Asked Questions

Q. Is this a medical device?
A. No. This app is not a medical device.
It is designed for gait analysis in health, research, and professional applications—not for diagnosis or treatment.

Q. What are the recommended conditions?
A. iPhone with an A15 Bionic chip or later, running iOS 17 or later.
Stable results are obtained with a circular walking area about 1 meter in diameter and adequate lighting.

Q. Is it free to use?
A. The app is currently free to download and use, with no in-app purchases or subscription fees.
Future updates may introduce optional paid features such as data sharing or cloud connectivity.

Q. Where is the measurement data stored?
A. All measurement data is stored locally on your device.

Q. Where is the data analysis performed?
A. All data processing is performed entirely on the device.
The app does not send any data for analysis, and no images containing individuals are ever transmitted.

Q. Will cloud storage or syncing be available in the future?
A. Cloud integration may be implemented in future updates.
Even then, no images containing individuals will be transmitted.
Any cloud-based features will require your explicit consent before data is shared — never automatically.

Q. Can it be used for research?
A. Yes. We welcome the use of G-AI for research and educational purposes.
Reporting your use is optional, but if you publish or present results using this app, we would appreciate hearing from you.
With your permission, we may feature your work on our Research Highlights page.
Such collaborations contribute to future technical development and academic partnerships.
