Student Coordinator, CYPHERMIND
A reverse prompt engineering challenge at the Zephyrus 8.0 technological summit, run by the Department of Computer Science. I co-led it with Gopika Ravindran, from the first plan to the day itself.

Hi, I’m Diuthendrh.
I’m a computer science student at Christ College, Irinjalakuda, and I’m curious about a lot of things. Coding is how I chase that curiosity, lately into computer vision and machine learning. Art is simply something I love.
Working with: Python, OpenCV, MediaPipe, Pygame, React, Flask, MySQL, C. Exploring: Docker and neural networks.
- Mindset
- Explore fearlessly. Think differently. Create relentlessly. Learn endlessly.
- Art
- Something I love. I draw whenever I get the chance.
- Hobbies
- Polymathy, music, curiosity.
- Based in
- Thrissur, Kerala, India. Christ College (Autonomous), Irinjalakuda.
MYST
Type with your eyes. Select with a wink.
Multi-Sensory Yielding Support Technology is a virtual keyboard for people with paralysis and motor disabilities. It needs only a standard webcam: no keyboard, mouse, touchscreen or special hardware.
Highlight jumps: 0.0/s
Gaze navigation
Horizontal gaze slides a highlight across the keys. Normalized iris tracking, EMA smoothing, a 7-frame majority vote and gaze locking keep it steady.
Wink to select
A deliberate wink picks the key. MYST tells it from a natural blink by comparing the blendshape scores of both eyes.
Help while typing
Bigram word prediction on the Brown corpus, autocorrect and text-to-speech, across QWERTY and symbol layouts.
What didn’t work
Before splitting navigation from selection, we tried pure gaze selection six ways. None held up on a webcam in real use.
- Sclera detection
- Iris-to-eyelid ratios
- Eyelid distance
- Vertical blendshapes
- Real-time calibrationSmall errors added up until the cursor drifted.
- Full 2D gaze estimationFine in controlled light, not in real use.
After 13+ versions: gaze navigates, a wink selects.
Specs
- Built with
- Python, OpenCV, MediaPipe FaceLandmarker, Pygame
- Tracks
- 478 face landmarks and 52 blendshapes
- Hardware
- A standard laptop webcam
- Interface
- 60 FPS Pygame UI, live settings panel, saved calibration

ARIA
Pinch the air to switch a fan and a bulb.
ARIA reads your hand through a webcam, draws a glass interface you point at, and sends commands over WiFi to an ESP32 that switches two relays. No touch, no remote.
- Click a device to send a command.
Index fingertip
Your fingertip is the cursor. Hover over a device to target it.
Thumb and index pinch
A click. Pinch over a device to switch it on or off.
Index and middle pinch
Grab a device and drag it anywhere on the screen.
How it’s wired
- LaptopWebcam, MediaPipe hand tracking, OpenCV interface
- WiFiTCP connection to the ESP32 on port 8080
- ESP32GPIO 23 to relay IN1, GPIO 22 to relay IN2
- RelaysIN1 switches the fan, IN2 switches the bulb
Protocol
| Device | Laptop sends | ESP32 replies |
|---|---|---|
| Fan | LED:ON LED:OFF | STATE:LED:… |
| Bulb | RELAY:ON RELAY:OFF | STATE:RELAY:… |
The wire names stay LED and RELAY to match the firmware. A mock ESP32 script listens on the same port, so the whole loop runs on one laptop.
Quorra
One platform for the people who run college events.
Students, coordinators, managers and admins each get their own dashboard and their own API routes. Coordinators plan, managers approve, admins look after accounts.
A dashboard per role
Each role sees only its own tools, backed by its own set of API routes.
Forms and approvals
Coordinators file proposal, expense, venue, advertisement, volunteer and media forms. Managers approve venues and role requests.
Reports and alerts
Stats for managers, notifications for everyone, and event exports at the click of a button.
