AI助手帮用户盯住目标，自动提醒走偏行为
State Your Intention to Steer Your Attention: An AI Assistant for Intentional Digital Living
- 用大模型分析截图和网址，判断当前行为是否符合用户声明的目标
- 三周实验中，相比规则提醒和只记录的对照组，专注度提升显著
- 支持主动澄清意图，通过反馈持续优化识别准确率
使用数字设备时，人们常受干扰，导致效率下降及负面情绪。为此，我们提出一种新型AI助手，能引导用户声明意图，评估当前活动是否与该意图一致，并在偏离时发出温和提醒。系统利用大语言模型分析屏幕截图、应用名称和网址，在行为偏离预期时触发通知。通过初始对话澄清和持续用户反馈，不断优化检测准确率。在22名参与者参与的三周内被试设计实地部署中，本系统相较于基于规则的意图提醒系统和仅记录行为的被动基线，显著提升了用户保持专注并使数字行为与意图对齐的能力。源代码已公开于https://intentassistant.github.io
原文摘要 · Abstract (English)
When working on digital devices, people often face distractions that can lead to a decline in productivity and efficiency, as well as negative psychological and emotional impacts. To address this challenge, we introduce a novel Artificial Intelligence (AI) assistant that elicits a user's intention, assesses whether ongoing activities are in line with that intention, and provides gentle nudges when deviations occur. The system leverages a large language model to analyze screenshots, application titles, and URLs, issuing notifications when behavior diverges from the stated goal. Its detection accuracy is refined through initial clarification dialogues and continuous user feedback. In a three-week, within-subjects field deployment with 22 participants, we compared our assistant to both a rule-based intent reminder system and a passive baseline that only logged activity. Results indicate that our AI assistant effectively supports users in maintaining focus and aligning their digital behavior with their intentions. Our source code is publicly available at https://intentassistant.github.io
