Design and Implementation of Wearable IoT Smart Gear for Real-Time Notification Display

Abstract

This paper presents the design, development, and evaluation of three innovative wearable systems engineered for seamless digital communication and notification management without dependency on smartphones. The work integrates an IoT Smart Gear, WiFi-native Smart Glasses, and a transparent holographic display system (EDITH). Unlike traditional Bluetooth-tethered commercial wearables, the proposed systems operate independently through direct WiFi and cloud connectivity, ensuring real-time operation, extended range, and full modular customization. Each system is developed using open-source hardware (ESP8266/NodeMCU) and 3D-printed enclosures for affordability and scalability. Field trials validate the robustness of these devices, demonstrating notification delivery success rates above 96%, latency between 145–425 ms, and multi-day battery performance. Results confirm that open and low-cost IoT-based architectures can rival or surpass traditional commercial wearables in functionality, cost efficiency, and independence.
