We are the Spatial Intelligence & Trusted Sensing Lab at Hunan University, led by Dr. Daibo Liu. We study how physical signals can help intelligent systems understand spaces, sense people and their surroundings, and protect privacy.
Our research brings together electromagnetic radiation, radio-frequency signals, signals of opportunity, and physiological signals. We connect sensing mechanisms, algorithms, and system design, with interests in spatial intelligence, trusted sensing, health, and security.
