Cross platform account unification and normalization

A matching engine comprising:

• a network interface;
• and
• a processor configured to:
• compare first metaverse metadata associated with a first account of a first metaverse and second metaverse metadata associated with a second account of a second metaverse;
• the first metaverse metadata comprising at least one of:
• first user data;
• first connection times that a first metaverse human-machine interface (HMI) associated with the first user connected to the first metaverse;
• first disconnection times that a first metaverse HMI associated with the first user disconnected from the first metaverse and time duration of activity by the first user with respect to the first metaverse;
• the second metaverse metadata comprising at least one of:
• second user data;
• second connection times that a second metaverse HMI associated with the second user was connected to the second metaverse;
• and
• in response to determining, from the first metaverse metadata and the second metaverse metadata, that the first user and the second user is a same user:
• when the first metaverse HMI is connected to the first metaverse, adapt, via the network interface, first behavior of the first metaverse based on the second metaverse metadata to control first physical feedback of the first metaverse HMI to indicate the first behavior;
• and
• when the first metaverse HMI is connected to the second metaverse, adapt, via the network interface, second behavior of the second metaverse based on the first metaverse metadata, to control second physical feedback of the second metaverse HMI to indicate the second behavior.
