The paper introduces MHVF, a training‑free framework for GUI grounding that uses multi‑hypothesis exploration and local visual verification with a single pretrained vision‑language model. MHVF generates spatial hypotheses from full‑screen predictions, refines them through zoomed re‑localization, and verifies candidate agreement with the instruction to resolve ambiguity. Experiments on eight benchmarks with five models show significant accuracy gains, notably improving UI‑Venus‑Ground‑7B by 4.3 pp on Mind2Web and raising Qwen2.5‑VL‑7B’s ScreenSpot‑Pro accuracy from 23.6 % to 53.6 %.
RankGround is a two‑stage framework for GUI grounding that uses a single Vision‑Language Model call per query. It introduces GroundRanker, a lightweight multimodal reranker that selects the most promising crop from a dense candidate set, trained with a two‑stage curriculum on ranking supervision data derived from existing grounding datasets. Experiments show RankGround outperforms strong baselines, achieving 1.4× faster inference and a 5.5% average improvement in localization accuracy over the second‑best method across all backbones and screen scales.

arXiv:2606. 14579v1 Announce Type: new Abstract: When applying Group Relative Policy Optimization (GRPO) for GUI Grounding, rollouts are sampled from a single screenshot view; groups often become either all failures on difficult instances or all successes on easy ones, yielding no useful relative advantage.
arXiv:2511. 00810v4 Announce Type: replace-cross Abstract: Graphical user interface (GUI) grounding is a key capability for computer-use agents, mapping natural-language instructions to actionable regions on the screen.
IVSGround introduces a lightweight view selector that learns to choose the most informative camera views for vision‑language model (VLM) based 3D visual grounding, replacing heuristic view selection. The selector is trained via a two‑stage rejection sampling process that uses feedback from a reasoning VLM to generate supervision signals. Experiments on ScanRefer and NR3D demonstrate that IVSGround consistently improves grounding accuracy over existing zero‑shot pipelines, underscoring the importance of selecting where to look for effective 3D visual grounding.

Jag is a method that transforms a compact pretrained multimodal model into a direct box predictor for visual grounding. It adds a lightweight regression head that, conditioned on the image and referring expression, outputs all four box coordinates in a single forward pass without sequential decoding. Geometric supervision jointly fine‑tunes the language backbone, visual merger, and regression head, leading to improved accuracy and lower latency compared to existing specialized grounding models.
ConClick introduces a contrastive learning framework that improves GUI grounding by teaching models to distinguish target interface elements from plausible distractors. The authors built ConClick-Data, a dataset of 4,292 challenging target-distractor pairs, and trained the model with listwise ranking and pairwise margin objectives, achieving significant accuracy gains on multiple benchmarks. An inference-time strategy called ReClick further boosts performance by revisiting promising regions and comparing competing predictions.
The paper introduces a controlled evaluation framework for interactive visual grounding in large vision-language models (LVLMs), examining how varying amounts of initial target information and dialogue affect performance. Experiments across four visual contexts and interaction protocols show that current LVLMs lag behind human baselines, especially when no initial description is given and information must be gathered through questions. The study also finds that LVLMs are poorly calibrated, often overestimating confidence, and that interactive grounding remains a significant challenge requiring visual matching, information seeking, and synthesis.
The paper introduces LBS (Look Beyond Screens), a vision‑language model that learns transferable visual observation behaviors from GUI grounding. LBS is first supervised with teacher‑generated GUI trajectories and then fine‑tuned via reinforcement learning to make multi‑turn crop‑and‑inspect decisions. Experiments show that LBS models based on Qwen3.5‑35B‑A3B and Qwen3.8‑27B outperform their baselines on PerceptionBench, HR‑Bench, and ChartQAPro, indicating that the learned observation strategies generalize beyond GUI‑specific imitation.
