Learning to Assess Heartbeat Observability for mmWave Heart-Rate Sensing

Yuxuan Hu, Shilin Shan, Jianfei Yang et al. · 2026

Contactless heart-rate sensing with millimeter-wave (mmWave) radar requires assessing whether individual measurements support reliable estimation. We study learning to assess heartbeat observability, defined as the readability of the heartbeat component in an acquired phase spectrum, for selective heart-rate estimation …

Visible Touch: Rendering Contact for Visuomotor Policies

Metin Alp Dogan, Edward Sun, Feng Xu et al. · 2026

Integrating contact information into visuomotor policies remains an open problem. Touch is essential to robust manipulation, yet most modern policies, including pretrained vision-language-action (VLA) models, operate from vision and proprioception alone. Existing approaches to closing this gap require specialized tacti …
