Enabling Proactive Driver Safety Through an IoT-Enabled Heart Rate Monitoring Platform
Overview
One of Japan’s largest automobile manufacturers set out to address a growing public safety concern: accidents involving elderly drivers caused by sudden health issues such as elevated heart rate, anxiety, or cardiac irregularities while driving.
Traditional health monitoring solutions were either manual, intrusive, or unsuitable for use during active driving. The client envisioned a proactive, automated health monitoring system that could continuously track a driver’s heart rate, detect critical conditions in real time, and trigger timely alerts—without distracting the driver.
Rysun partnered with the client to design and deliver a first-of-its-kind IoT-integrated mobile application, combining wearable technology, intelligent alerts, and real-time analytics to help prevent accidents and enhance driver safety.

IoT-Integrated Heart Rate Monitoring Mobile Application
Challenge
Lack of passive, real-time health monitoring put elderly drivers at risk during active driving.
The Challenge
Japan faces a unique demographic challenge with a rapidly aging population and a high number of elderly drivers. The client identified a critical gap in existing safety and health solutions:
- Accidents caused by sudden heart rate fluctuations, anxiety, or cardiac issues while driving
- No automated or passive way to monitor driver health conditions in real time
- Existing apps required manual interaction (such as fingerprint scanning), which was unsafe and impractical during driving
- Need for instant alerts and escalation mechanisms during prolonged critical health conditions
- Requirement for a solution that seamlessly integrates with smart bands and vehicle usage without disrupting the driving experience
The client needed a simple, fast, and reliable system that worked automatically in the background and supported immediate decision-making.
Rysun’s Solution:
Rysun designed and implemented an IoT-enabled iOS mobile application integrated with wearable devices to continuously monitor heart rate while the user is driving. The solution combines real-time data capture, intelligent thresholds, and multi-modal alerting to proactively safeguard drivers—especially elderly users.
Key Capabilities Delivered
- Wearable & IoT Integration: Smart band integration using secure pairing via barcode and unique codes to enable continuous heart rate monitoring
- Real-Time Heart Rate Monitoring: Automatic tracking of heart rate as soon as the user begins driving, without manual intervention
- Critical Condition Detection (40-Second Rule): Intelligent logic to detect sustained abnormal heart rate conditions over a defined time threshold
- Multi-Modal Alerts & Notifications
- Voice (VOIP) alerts
- Push notifications
- Full-screen color-based visual indicators reflecting health status (critical, moderate, normal)
- Emergency Action Enablement: One-tap calling to pre-configured emergency contacts when critical conditions persist
- Analytics, History & Reporting
- Daily, weekly, and monthly heart rate history
- Graphs and charts for trend analysis
- Termination mode for controlled session tracking
