PROBLEM
Singapore experienced its hottest year on record in 2023, with temperatures soaring due to climate change and the urban heat island effect. As a densely built city with high humidity, prolonged heat exposure poses significant risks, particularly for outdoor workers. Without adequate monitoring and intervention, heat stress can lead to severe health issues, reduced productivity, and economic losses.

Introducing,
A 3-Part Gait Monitoring Solution
Real-time monitoring using a wearable waist IMU, mobile app, and admin dashboard
TRACK MOVEMENT WITH PRECISION
Monitor real-time 3-axis acceleration with our advanced IMU sensor. Gain valuable insights into movement patterns for enhanced analysis and optimization.
DETECT FATIGUE EARLY
Identify abnormal gait patterns and fatigue-related changes before they become issues. Our system helps prevent strain and injury through proactive monitoring.
SYNC DATA SEAMLESSLY
Automatically upload movement data to the cloud dashboard for effortless tracking, visualization, and analysis—accessible anytime, anywhere.
WHY GAIT MONITORING?
Gait parameters are measurable aspects of walking that provide insights into a person’s movement patterns. Fatigue affects movement long before noticeable symptoms appear, making gait analysis a powerful early detection tool. Subtle gait changes, like shorter steps or instability. signal early fatigue—impacting safety and productivity. By leveraging gait monitoring, we provide proactive safety insights, helping workers stay productive while minimizing heat-related injuries.
HOW DOES IT WORK?
Our System Architecture
Wearable IMU
Captures raw motion data from the user’s waist in real time using a built-in inertial measurement unit (IMU)
Mobile App
Performs on-device gait analysis using custom algorithm
Cloud Database
Receives processed gait data from the app, stores it securely, and handles requests from the dashboard
Dashboard
Visualizes workers’ gait patterns and alerts abnormalities using real-time data pulled from the cloud
OUR FEATURES
WAIST ATTACHMENT IMU DEVICE
Engineered for waist-level attachment, providing comfort and unobtrusive wear throughout daily tasks
Uses Bluetooth to seamlessly transmit real-time gait data to the mobile application without the need for cables
Offers both wired and wireless charging, with a 26-hour battery life and fast recharge capability (under 2 hours)
MOBILE APP
It collects raw IMU data from the device and provides real-time status updates (e.g., IDLE vs WALKING)
The app processes data to detect gait cycles and calculates gait parameters to identify abnormal patterns
Processed data is automatically uploaded to AWS, enabling centralized data access.
DASHBOARD
Managers can view live gait data from multiple workers simultaneously
Uses a traffic light model to easily highlight abnormal gait patterns, helping with quick decision-making
Allows selection of individual users to review detailed gait metrics and historical data for tailored monitoring
USER JOURNEY
Attach SafeGait to your belt securely behind
Connect the device to the mobile app via Bluetooth
Start walking to detects movement patterns in real time
Data is sent to the cloud-based dashboard for monitoring
If abnormal gait is detected, the dashboard will flag irregularities
ACKNOWLEDGMENTS
We would like to thank our capstone mentors: Professor Massimiliano Colla, Professor Grace Kong, Dr. Bernard Tan, and Lye Peng for their continued support and guidance towards SafeGait’s completion and success.
