PenguTime.

The idea arose from a problem familiar to me: modern teenagers spend more than 7 hours a day on digital devices, yet constantly feel they lack time for studying. The smartphone has become the main factor distracting from focused work.Instead of fighting this with willpower alone, I decided to create a technological solution — a device capable of automatically tracking the moment of distraction and gently reminding the user about it without irritating them.This is how PenguTime came about — a "smart penguin" based on Raspberry Pi 4 with computer vision (YOLO26n) that sees when a person leaves their workplace or picks up their phone, and reacts with wing movement, sound, and lighting. The PenguFocus mode implements the Pomodoro technique, and the PenguCoin gamification turns self-discipline into a game.The goal is to help teenagers consciously manage their time by combining computer vision technology with a friendly way of interaction, suitable for home, school, and smart home systems.
