Free Canvas AR Drawing Tool

February 2022

Free Canvas (Augmented Reality) is a drawing tool for children of age 2-8 where they can interact with webcam and draw figures by joining dots and improving creativity. Works by recognizing hand and finger points.

Augmented Reality Computer Vision Education

Agentic Chatbot Assistant

March 2021

Designed and created a chatbot for personal use which can perform certain tasks on Ubuntu OS. The data was made from scratch, and the model was trained on the data. Features speech-to-text module from google.

NLP Speech Recognition Automation

Snake Game with Random Forest

January 2021

Designed and built a snake game on Webcam's screen where you can see yourself (like a mirror) and the snake playing the game itself. Random Forest gave the best accuracy. Data for training was generated from scratch by playing 100 games manually.
