CheckMate: A 3D spatial twin of my best friend's hostel room so he stops leaving his charger behind

This submission, for the Hacktoberfest Weekend Challenge, aims to build a solution for a friend's recurring problem. The friend, Kanwal, has a habit of leaving behind essential items, like his charger, which he desperately needs only minutes after departing from their hostel. The challenge with traditional reminders is that they are purely digital and don't connect to the physical items, making it hard to remind Kanwal of what he's left behind.

To address this, CheckMate was created. It's a trip-aware packing assistant based on a 3D representation of Kanwal's actual hostel room. This 3D room, built using Three.js, includes furniture, items, and even a wall switchboard that closely resembles the real-life reference photograph. The 3D representation helps the user relate the interface to their real surroundings and makes it easier to understand what should be packed.

The app includes interactive belongings that can be selected within the scene. These interactive objects have visual indicators and status badges to help distinguish what has been packed. The app also uses AI and voice capabilities through Google Gemma to generate packing recommendations based on the trip context, the items in the room, and the user's past packing mistakes.

So, CheckMate is not just a simple checklist app. It's a more sophisticated system that uses spatial interfaces, AI, and a 3D room model to help users remember what they've left behind. This project shows how technology can be creatively used to solve everyday problems, making our lives a little easier.
