Plain Language Accessible to non-experts

Imagine you're in a kitchen cooking a meal. OmniParser is like a smart assistant that can identify every tool and ingredient in the kitchen and tell you how to use them to complete a dish. It doesn't need to look at a recipe (HTML information); it just observes the kitchen environment (UI screenshot) to help you cook. This ability makes it perform well in different kitchens (platforms).

ELI14 Explained like you're 14

Imagine you're playing a game, and OmniParser is like a super helper that can identify every button and icon on the game interface and tell you how to operate them to win the game. It doesn't need to look at a guide; it just observes the game screen to help you complete tasks. This ability makes it perform well in different games! Isn't that cool?

Abstract

The recent success of large vision language models shows great potential in driving the agent system operating on user interfaces. However, we argue that the power multimodal models like GPT-4V as a general agent on multiple operating systems across different applications is largely underestimated due to the lack of a robust screen parsing technique capable of: 1) reliably identifying interactable icons within the user interface, and 2) understanding the semantics of various elements in a screenshot and accurately associate the intended action with the corresponding region on the screen. To fill these gaps, we introduce \textsc{OmniParser}, a comprehensive method for parsing user interface screenshots into structured elements, which significantly enhances the ability of GPT-4V to generate actions that can be accurately grounded in the corresponding regions of the interface. We first curated an interactable icon detection dataset using popular webpages and an icon description dataset. These datasets were utilized to fine-tune specialized models: a detection model to parse interactable regions on the screen and a caption model to extract the functional semantics of the detected elements. \textsc{OmniParser} significantly improves GPT-4V's performance on ScreenSpot benchmark. And on Mind2Web and AITW benchmark, \textsc{OmniParser} with screenshot only input outperforms the GPT-4V baselines requiring additional information outside of screenshot.
