Engaging with AI assistants to gather essential information in a timely manner is becoming increasingly common. Traditional activation methods, like wake words such as Hey Siri, Ok Google, and Hey Alexa, are constrained by technical challenges such as false activations, recognition errors, and discomfort in public settings. Similarly, activating AI systems via physical buttons imposes strict interactive limitations as it demands particular physical actions, which hinders fluid and spontaneous communication with AI. Our approach employs eye-tracking technology within AR glasses to discern a user's intention to engage with the AI assistant. By sustaining eye contact on a virtual AI avatar for a specific time, users can initiate an interaction silently and without using their hands. Preliminary user feedback suggests that this technique is relatively intuitive, natural, and less obtrusive, highlighting its potential for integrating AI assistants fluidly into everyday interactions.

翻译：及时与AI助手互动以获取关键信息正变得越来越普遍。传统的激活方法，如"Hey Siri"、"Ok Google"和"Hey Alexa"等唤醒词，受限于误激活、识别错误及公共场合使用不适等技术挑战。类似地，通过物理按钮激活AI系统因其需要特定肢体动作而施加了严格的交互限制，阻碍了与AI之间流畅自然的交流。我们的方法利用AR眼镜中的眼动追踪技术来识别用户与AI助手互动的意图。通过持续注视虚拟AI形象达到特定时长，用户无需动手即可静默发起交互。初步用户反馈表明，该技术相对直观、自然且侵扰性较低，凸显了其将AI助手流畅融入日常交互的潜力。
