 💡 **Rethink how humans interact with digital interfaces**: humans do NOT calculate precise screen coordinates before acting—they perceive the target element and interact with it directly.
 
-🚀 **We propose _GUI-Actor_, a VLM enhanced by an action head, to mitigate the above limitations.** The attention-based action head not only enables GUI-Actor to peform coordinate-free GUI grounding that more closely aligns with human behavior, but also can generate multiple candidate regions in a single forward pass, offering flexibility for downstream modules such as search strategies.

 ➕ **We design a _grounding verifier_ to evaluate and select the most plausible action region** among the candidates proposed from the action attention map. We show that this verifier can be easily integrated with other grounding methods for a further performance boost.
