Navigation Reimagined
for Every Person
A precision spatial-awareness platform that connects visually impaired users with their caregivers in real time — powered by Edge AI, IoT sensors, and a design philosophy rooted in human dignity.
360° Spatial Radar
Four ultrasonic and Time-of-Flight sensors map the user's surroundings in every direction — delivering obstacle alerts with millimetre precision.
Edge AI Processing
An onboard ESP32-CAM runs a real-time AI pipeline with no cloud dependency — instant, localised object recognition that works even without an internet connection.
Haptic Feedback Engine
Directional vibration pulses encode both the proximity and bearing of obstacles — giving the user clear spatial information through touch alone, without breaking stride.
About Maarg Darshan Care
A wearable AI-powered cap that restores spatial awareness for visually impaired individuals — enabling independence, confident movement, and safety-focused caregiving, every single day.
Maarg Darshan Care is a next-generation assistive technology platform built to restore independence for individuals living with visual impairments. At its core is a wearable smart cap embedded with ultrasonic transducers, Time-of-Flight modules, and an ESP32-CAM — all working in harmony to build a continuous, real-time 360° picture of the space around the user.
The platform connects the wearer directly to their caregivers through a live web dashboard displaying sensor telemetry, a camera feed, GPS coordinates, and system alerts — giving families and support workers the visibility and reassurance they need, from wherever they are.
360° Obstacle Detection
Four ultrasonic sensors sweep all directions at once, building a continuous spatial picture with colour-coded severity levels — updated in real time.
Live Camera Streaming
The onboard ESP32-CAM streams video directly to the caregiver dashboard with zero cloud dependency.
Haptic Feedback Engine
A precision vibration motor translates obstacle data into directional pulses so users understand their surroundings through touch alone.
Live GPS Tracking
Real-time coordinates and a visual path trace appear on the caregiver dashboard the moment the user starts moving.
Voice Guidance
Spoken alerts are delivered through the caregiver's device using the Web Speech API — clear, natural Indian English.
Emergency SOS
A single button press sends an immediate alert to registered contacts and emergency services with the user's live GPS coordinates.
+ Wi-Fi MJPEG
Live Dashboard
The Hardware Node
Zero-latency collision avoidance engine isolated from network drops. Features a dual-microcontroller design (Arduino + ESP32) to guarantee real-time physical safety while simultaneously maintaining high-bandwidth live video streaming.
The User Node
An invisible, hands-free auditory interface anchored by the "Hey Vision" wake-word. Executes RAM-defiant background processing and Bluetooth SCO routing overrides so the visually impaired user is never disconnected from the AI.
The Cloud Node
The central synchronization hub. Cryptographically pairs the user to their caretaker, securely routing high-frequency spatial telemetry, SOS interrupts, and real-time AI contextual processing at lightspeed.
The Guardian App
Engineered for aggressive emergency interception. Uses system-level BroadcastReceivers to pierce lock screens, maximize volume, and trigger sirens — even if the app is killed by the phone's operating system.
The Web Console
The high-fidelity command center. Dynamically renders a live 3D WebGL mirror of the user's hardware, provides continuous MJPEG camera streaming, and tracks real-time cartographic GPS coordinates.
Our Mission for a Better World
We believe that visual impairment should never be a barrier to independence, safety, or living a confident and fulfilling life.
Every step taken outside should be a step taken with confidence. Our primary mission is to replace fear with freedom. By providing a reliable, 360-degree awareness of their surroundings, we empower visually impaired individuals to step out, explore, and navigate their daily lives without constantly relying on physical guidance from others.
We harness the power of modern innovation to solve real-world challenges. By integrating ultrasonic sensors, advanced Time-of-Flight lasers, and Edge AI processing through the ESP32-CAM, we transform a simple wearable cap into a powerful "digital eye."
True safety involves a support system. Our live dashboard provides caretakers with real-time GPS tracking, a live camera feed, and instant emergency SOS alerts. We bridge the distance between users and their loved ones, providing unparalleled peace of mind.
Advanced assistive technology is often treated as a luxury, priced far beyond the reach of those who need it most. We are on a mission to democratize mobility by providing enterprise-grade safety at a fraction of the traditional cost.

Device Guide
A quick setup and operation guide for your Maarg Darshan device.
1. Powering On & Hardware Setup
Press and hold the main recessed power button on the Smart Cap for 3 seconds. The localized bone conduction transducers will vibrate once, and the LED indicator will pulse blue, signaling that the dual-microcontroller engine is active and ready for pairing.
2. Pairing the User Application
Open the Maarg Darshan mobile app. The application is completely hands-free and voice-guided. It will automatically scan and pair with the cap via Bluetooth. Once connected, the app routes all AI audio directly through the cap's bone conduction hardware to keep your ears unoccluded.
3. Caretaker Cryptographic Linking
The caretaker must download the separate Caretaker App or log into the Web Dashboard. For absolute privacy, open searches are disabled. The caretaker must enter the secure, pre-generated pairing code generated by the User App to establish a cryptographically linked pipeline.
4. Testing the SOS Pipeline
Test the connection by pressing the recessed physical SOS button on the cap. The Caretaker App will instantly intercept the payload, forcing a red lock-screen override and sounding a maximum-volume siren on their phone. The caretaker can then press "Acknowledge" to send a voice confirmation back to you.
5. Initializing the Spatial AI
With setup complete, simply say "Hey Vision, what is around me?". The secondary microcontroller will capture an optical frame and route it to the cloud, returning a vivid spatial description of your environment within milliseconds.

Frequently Asked Questions
Find answers to common questions about the Maarg Darshan system.
Does the cap require a constant internet connection to work?
No. The core obstacle detection runs locally on the edge using the ESP32 microcontroller, ensuring immediate haptic feedback even without Wi-Fi. However, live camera streaming and GPS tracking require a connection to sync with the caregiver dashboard.
How does the caregiver receive an SOS alert?
When an SOS is triggered, the system instantly pushes a high-priority alert to the web dashboard, sounding an alarm and logging the exact GPS coordinates.
How long does the battery last on a single charge?
The system is optimized for continuous daily use, providing reliable battery life to ensure the user remains connected and safe throughout their daily routines.
Can the haptic feedback be adjusted?
The vibration intensity scales dynamically based on how close the obstacle is—stronger vibrations mean the object is closer, providing an intuitive sense of space.
