This document describes a proposed mobile application for interior design using markerless augmented reality. The application would allow customers to visualize 3D models of furniture and appliances in their real-world environment in real-time before purchasing. It operates using motion tracking, environmental understanding, and light estimation from the mobile device's sensors and camera. The goal is to give customers a more immersive experience when designing interior spaces compared to traditional static 2D design methods. It aims to reduce time, effort and uncertainty in furniture selection by allowing users to preview items virtually in their own homes.
