Augmented Reality Indoor Navigation with Smart Appliance control

This proposed work explores the application of augmented reality (AR) for indoor navigation in emergency situations and large spaces using Unity NavMesh and the A* algorithm. It provides real-time information about college class-rooms and enhances accessibility for people with disabilities. The proposed system utilizes Vuforia and Unity to construct the AR environment, integrating QR code scanning using the ZXING SDK, as well as the smart control of light bulbs, fans, and other appliances through ESP32, relay modules, and the Blynk API. Experimental results demonstrate the effectiveness of our approach in improving navigation accuracy and accessibility for users. Furthermore, the system’s real-time updates, user-friendly interface, and remote appliance control offer a versatile solution for various indoor environments. The proposed work presents a detailed explanation of the literature review, the operating architecture, discusses its social impact, limitations, and future scope, highlighting its potential to revolutionize indoor navigation and accessibility for all.
