TouchThinker: Scaling Tactile Commonsense Reasoning to the Open World with Large-scale Data and Action-aware Representation

In three linesTouchThinker is a tactile-language framework for touch-based commonsense reasoning. Authors construct TouchThinker-1M, a million-scale dataset covering 415 objects, 8 scenarios, and 7 sensor types, and introduce action-aware modeling to improve tactile representation efficiency and enable open-world generalization.
