  Metaverse is an immersive shared space that remote users can access through
virtual and augmented reality interfaces, enabling their avatars to interact
with each other and the surrounding. Although digital objects can be
manipulated, physical objects cannot be touched, grasped, or moved within the
metaverse due to the lack of a suitable interface. This work proposes a
solution to overcome this limitation by introducing the concept of a Physical
Metaverse enabled by a new interface named "Avatarm". The Avatarm consists in
an avatar enhanced with a robotic arm that performs physical manipulation tasks
while remaining entirely hidden in the metaverse. The users have the illusion
that the avatar is directly manipulating objects without the mediation by a
robot. The Avatarm is the first step towards a new metaverse, the "Physical
Metaverse", where users can physically interact each other and with the
environment.
