A 20-subject LOSO study finds fused radar-thermal sensors reach 0.871 median balanced accuracy for bed presence but only 0.674 for four-class posture, with prone recall 0.50 and precision 0.41, concluding raw range-FFT access is the next hardware step.

Sensor-Stack Limits on Contactless In-Bed Body Position: A 20-Subject Multimodal Radar + Thermal LOSO Characterization
A 20-subject LOSO study finds fused radar-thermal sensors reach 0.871 median balanced accuracy for bed presence but only 0.674 for four-class posture, with prone recall 0.50 and precision 0.41, concluding raw range-FFT access is the next hardware step.
