  Future fully interconnected virtual reality (VR) systems and the Tactile
Internet diminish the boundary between virtual (online) and real (offline)
worlds, while extending the digital and physical capabilities of humans via
edge computing and teleoperated robots, respectively. In this paper, we focus
on the Internet of No Things as an extension of immersive VR from virtual to
real environments, where human-intended Internet services - either digital or
physical - appear when needed and disappear when not needed. We first introduce
the concept of integrated online-to-offline (O2O) communications, which treats
online and offline channels as complementary to bridge the virtual and physical
worlds and provide O2O multichannel experiences. We then elaborate on the
emerging extended reality (XR), which brings the different forms of
virtual/augmented/mixed reality together to realize the entire
reality-virtuality continuum and, more importantly, supports human-machine
interaction as envisioned by the Tactile Internet, while posing challenges to
conventional handhelds, e.g., smartphones. Building on the so-called
invisible-to-visible (I2V) technology concept, we present our extrasensory
perception network (ESPN) and investigate how O2O communications and XR can be
combined for the nonlocal extension of human "sixth-sense" experiences in space
and time. We conclude by putting our ideas in perspective of the 6G vision.
