When Ground Truth Is the Bottleneck: How Self-Report Label Properties Constrain Multimodal User-State Estimation in Human–Robot Collaboration

Self-report instruments such as the NASA-TLX, STAI, and SAM routinely serve as ground-truth labels for multimodal user-state estimation, yet their measurement properties are rarely examined as constraints on prediction. In the MultiPhysio-HRC dataset (52 participants, 10 task con...
