## Summary

DreamTacVLA proposes a framework that grounds VLA models in contact physics, learning contact dynamics by predicting future tactile signals. The model uses hierarchical perception, taking high-resolution tactile images as micro-vision inputs combined with wrist-camera local vision and third-person macro vision, and uses a Hierarchical Spatial Alignment (HSA) loss to align tactile tokens with their spatial counterparts in the wrist and third-person views.
