This tutorial delves into the integration of Magic Leap One with the PubNub Unity SDK to enable gesture-based control of internet-connected devices, particularly focusing on manipulating an RGB LED's state and color. Using Unity and Magic Leap's hand tracking API, users can send messages to a control channel on PubNub by performing specific hand gestures, such as thumbs, fists, or fingers, which are detected with high accuracy to trigger actions like turning the LED on or off and cycling through color modes. The tutorial details the setup and configuration of the development environment, including the necessary software and hardware components like the ESP8266 development board and NodeMcu. It guides users through creating a new Unity project, importing the Magic Leap Unity package, and integrating PubNub for real-time communication to control the LED, all while emphasizing the adaptability of the tutorial to future SDK updates. Additionally, it outlines testing and deployment procedures using the Magic Leap Remote, Play Mode, and actual device deployment, providing users with a foundation to further explore IoT applications with Magic Leap technology.
