Actually, I envision EML as developing in stages corresponding to different
"levels" in a fully mature EML:
"Level 1 EML" is confined to strictly descriptive terms corresponding to
actuation of the human muscular/affective system, i.e. the "appearances" you
talk about, Tom. The vast majority of terms in "Level 1 EML" would address
the activity of facial musculature, although whole-body gestural positioning
should also be included.
"Level 2 EML" would be in essence a programming language for scripting
streams of Level 1 commands. I can foresee a healthy market developing for
various useful and interesting scripts.
"Level 3 EML" would add a higher level of structure and would amount to a
"Character Mark-up Language" (CML) or "Personality Mark-up Language" (PML).
The idea with Level 3 EML would be to group Level 2 scripts into
characteristic program calls specific to individual personalities or
characters. Thus, Level 3 EML achieves expression of the "complex internal
states" you mention, Tom. I envision a programming tool that would allow an
author to specify personality traits for a character that would automagically
craft characteristic Level 2 scripts in response to high-level terms such as
the ones you mention, e.g. anomie, nostalgia, etc. An EML author could tweak
these automatic scripting parameters to generate a "personality type" for a
character. At that point, one could see crafting interactive environments in
which calls are made to Level 3 EML terms, which activate Level 2 scripts
specific to particular characters. Thus, a dark, chaotic VR setting
containing threats to a character's safety could invoke "fear", and each
character would express that emotion in their characteristic way. Likewise,
the occurrence of verbal input could generate specific Level 2 scripts from a
"virtual person" based on their Level 3 "character traits".
