Deep Analysis

Background

In recent years, visual language models (VLMs) have been widely applied in mobile device operations, automating user instructions by simulating human actions. However, existing VLMs often face challenges with unexecuted and inefficient subtasks under multi-agent architectures due to a lack of experience in GUI scenarios.

Core Problem

Current visual language models face dual challenges of unexecuted and inefficient subtasks under multi-agent architectures. These issues mainly arise from VLMs' lack of experience in GUI scenarios, leading to inefficient task execution.

Plain Language Accessible to non-experts

Imagine you're in a kitchen cooking a meal. You have a recipe that tells you what to do at each step. CHOP is like a smart assistant that helps you break down the complex recipe into simple steps, like chopping vegetables or boiling rice. Each step is a subtask, and CHOP ensures that each subtask is completed smoothly, just like an experienced chef who knows exactly what to do and when. This way, you can complete the entire recipe faster and better without wasting time.

Abstract

The advancement of visual language models (VLMs) has enhanced mobile device operations, allowing simulated human-like actions to address user requirements. Current VLM-based mobile operating assistants can be structured into three levels: task, subtask, and action. The subtask level, linking high-level goals with low-level executable actions, is crucial for task completion but faces two challenges: ineffective subtasks that lower-level agent cannot execute and inefficient subtasks that fail to contribute to the completion of the higher-level task. These challenges stem from VLM's lack of experience in decomposing subtasks within GUI scenarios in multi-agent architecture. To address these, we propose a new mobile assistant architecture with constrained high-frequency o}ptimized planning (CHOP). Our approach overcomes the VLM's deficiency in GUI scenarios planning by using human-planned subtasks as the basis vector. We evaluate our architecture in both English and Chinese contexts across 20 Apps, demonstrating significant improvements in both effectiveness and efficiency.
