本文以“媒介导航”为关键概念，借用技术哲学中奥德修斯的“桨”作为导航媒介的意象，以鼠标对应计算机虚拟空间、手机对应移动网络时代的数字城市赛博空间，以阐释随着计算机、移动网络、人工智能等技术的发展，柏拉图描绘的早期人类文明中的双重导航——实体空间和话语空间实践——正趋向融合的历史进程。由此，大众媒介的“受众”变身为数字时代的“用户”与“领航人”，媒介与人、社会的关系拓展到一个崭新层面：媒介作为一个技术机器系统，与有机体系统、社会系统互嵌共生，成为直接驱动人类社会运作的动力和机制。

This article takes “media navigation” as the key concept and adopts Odysseus’s “oar”, from the philosophy of technology, as the image of media navigation. By analyzing the role of the mouse in navigating the virtual space and that of the mobile phone in urban cyberspace in an era of mobile internet, this paper explores and illustrates the historical process of dual navigation in Plato’s sense, namely how, as technology develops, including computers, mobile internet, artificial intelligence etc., navigation practices in physical and discursive spaces are becoming increasingly integrated. During this process, the “audience” of the mass media has become “user” and “steersman”, and the relationship between media, human and society has been expanded and reinvented. The media, as a technological machine system, in its deep association with the organic and the social, has become the force and mechanism that drives the human society.
