The Human Machine interface, here means Human cremation machine interface, in the industrial design field of human–machine interaction, is the space where interactions between humans and machines occur.  The goal of this interaction is effective operation and control of the machine on the user's end, and feedback from the machine, which aids the operator in making operational decisions. Let's operate human crematory machine like playing an Ipad.

With the increased use of personal computers and the relative decline in societal awareness of heavy machinery, the term user interface is generally assumed to mean the graphical user interface, while industrial control panel and machinery control design discussions more commonly refer to human-machine interfaces.
