The perception of human beings has undergone a remarkable transformation, evolving from mere natural biosensors to sophisticated sensors and sensor networks. These networks, comprising trillions of interconnected devices, have the capability to perceive a wide range of contexts for human beings, thereby laying the groundwork for the emerging Internet of Things (IoT). However, despite the immense potential of sensor technologies, they face several limitations that hinder their practical application. These limitations primarily revolve around deployment costs and usability, making them unacceptable for widespread use. Consequently, there is a growing demand for a wireless, sensorless, and contactless sensing paradigm that seeks to enhance human perception and convenience.

In recent years, wireless sensing technologies have experienced significant advancements, enabling sensors to detect wireless signals that were initially intended for data transmission or lighting. By analyzing the signal measurements on the receiver end, valuable information can be extracted to convey the sensing results. This approach has opened up new possibilities for smart wireless sensing, as it eliminates the need for dedicated sensors and promotes the integration of IoT.

One promising area of research is the utilization of ambient Wi-Fi, RFID, Bluetooth, ZigBee, and television signals for smart wireless sensing. By leveraging these existing wireless signals, researchers aim to create intelligent systems that can perceive and analyze human behavior without the need for physical contact. This not only enhances convenience but also opens up opportunities for real-time monitoring and personalized interactions.

To address the challenges and opportunities presented by wireless sensing, this book offers a comprehensive and in-depth exploration of the field. Specifically, with a focus on Wi-Fi-based sensing for understanding human behavior, it adopts a top-down approach to introduce three key topics: human detection, localization, and activity recognition. By presenting the latest advances in smart wireless sensing based on an extensive review of state-of-the-art research, the book aims to promote the further development of this area and also contribute to interdisciplinary research.

In conclusion, the evolution of human perception from natural biosensors to powerful sensors and sensor networks has set the stage for a new era of innovation. Wireless sensing technologies, driven by advancements in signal processing and machine learning, have the potential to revolutionize the way we interact with our environment and enhance our daily lives. However, it is essential to address the limitations related to deployment costs and usability to make these technologies more practical and accessible. With continued research and development, we can expect to see the emergence of wireless, sensorless, and contactless sensing paradigms that will redefine the way we perceive and interact with the world around us.
