Book

Gesture-Based Embedded Systems explores the principles, technologies, and practical implementation of intelligent systems that enable natural, touchless human–computer interaction. The book presents a systematic journey from gesture sensing and data acquisition to signal processing, gesture recognition, Edge AI, TinyML, real-time embedded architecture, power management, and human-centered interaction design.It examines a wide range of sensing technologies, including ultrasonic, infrared, radar, vision-based, and wearable approaches, while emphasizing the engineering trade-offs involved in selecting appropriate hardware and algorithms. Real-world applications across healthcare, smart homes, robotics, automotive systems, industrial automation, hospitality, education, and consumer technology are also discussed.A practical touchless smart restaurant menu case study brings the concepts together through hardware integration, sensing, firmware, gesture-based control, and embedded system design.This book is intended for students, researchers, engineers, developers, and technology enthusiasts seeking a practical foundation for designing and understanding gesture-based embedded systems.
