AR Interior Design App with Furniture Placement – IT & Computer Engineering Guide
1. Project Overview
The AR Interior Design App enables users to visualize and place 3D models of furniture and home decor in real environments using mobile devices. It supports spatial mapping, real-time object scaling, and occlusion-based interaction for realistic visualization. The app assists users in interior planning, home renovation, and e-commerce visualization.
2. System Architecture Overview
- Camera Feed & Spatial Mapping: Captures room layout
and surfaces
- Object Placement Engine: Places 3D furniture models in real space
- UI/UX Controller: Manages interaction like rotation, scaling, deletion
- Furniture Catalog Manager: Accesses furniture models from a cloud database
- Scene Save/Export Module: Stores room layouts or generates screenshots
