FocusGUI improves multi-step omni-modal GUI agents by dynamically prioritizing relevant inputs

FocusGUI addresses Sequential Distraction in omni-modal GUI agents by adaptively compressing relevant perceptual channels into a compact latent injected into a frozen decoder, improving Type Match by +33.2 points and Exact Match by 3× over frozen backbones across four models.

Based on the paper Focused Omni-Modal GUI Agents by Fuyao Zhang, Wenwen He, Jiaming Zhang, Yurong Hao and 5 others

Challenges of multi-step omni-modal GUI interaction and Sequential Distraction

Modern GUI agents operate over streaming omni-modal inputs including screenshots, audio, video, interaction history, and device states, requiring them to select relevant evidence for each action step. However, the relevance of each modality is transient and sparse: the dominant modality can switch between adjacent steps, and irrelevant inputs can distract the agent.

Because the agent's executed actions feed back into the observation context, errors in selecting relevant information compound over time, causing Sequential Distraction, where the agent drifts irreversibly from the correct trajectory.

Existing methods attempt to reduce distraction by cropping or refining visual inputs, but these approaches fail to handle non-visual modalities and often discard essential context needed for grounding actions. The problem is not the amount of input but the lack of guidance on how to prioritize it at each step.
