[Korea-chapter] [h-anim] Use Cases for consideration

[Joe D Williams]

>  "medical realism"

I think medical realism means that the humanoid is the model for some 
specific human or typical human and has all the realistic human items 
accessible by realistic traverse or section navigation and exhibits 
realistic interactions with other humanoids or non-human objects.

This is why the next thing we need is a realistic skin drawn directly 
in skeleton space. To compose the basis for this skin it is important 
to standardize the name and typical location of every important 
external reference location. Then, the skin can be drawn and bound 
using these points. Within a wide range of human dimensions, the 
internal skeleton reference locations and dimensions along with these 
external skin reference locations can be adjusted to accomodate any 
size human. Then comparable realistic X3D H-Anim characters can 
exchange skeleton and continious mesh deformable skin animations.

So, how dense, meanig number of vertices,  are necessary to provide a 
minimum best practice skin? The answer is the same for high fidelity 
"medical" or any other realtime dynamic humanoid animation. How much 
money ya got? How fast d'ya wanna Go? At the top end of medical or 
entertainment the answer is: To be as realitic as possible and show 
everything; every interaction with the environment that is pertinent.
If it is noticably non-realistic by the author or another human, or 
for that matter another humanoid, it is pertinent.

Obviously, for X3D to 'get skin in the game' for our X3D example sets, 
I  would say the minimum "medical" skin density is (1) important 
'standard' human dimension measurement points, (2) every end effector 
and haptic location, and (3) locations where intensive monitoring 
manual or automated medical instrumentation is used. Please note that 
we have some parts of this now, with the list of Annex B in 
ISO_IEC_FCD_19774, and previous editions.

For detailed animation of specific areas such as hands and face, more 
point density i necessary. Many of these points are described in past 
versions of the H-Anim standard. See Appendix B: Suggested Displacer 
Nodes in H-Anim1.1 at http://www.h-anim.org/

If we can approach this task of using medical and entertainment 
(actually useless to try to distinguish these) use cases to produce a 
set of 'standard' skins it will give a comprehensive overview of 
current best practices and thus give a great standards-track starting 
point for people wishing to create a realistic model of themselves or 
others using standards-track tools and transportable animations.
This is just a relatively simple next step. And let's not forget one 
important use case for X3D H-Anim: Remote control human surgery. This 
is when the local actuator performs the detailed surgery using AI and 
assistance from a remote instrumented human (or higher level AI maybe) 
... this is not so far in the future.
To get there we need to have a best practices virtual humanoid that is 
complete enough for a real surgeon or an AI surgeon to practice on.

Thanks and Best Regards,

Subject: [h-anim] Use Cases for consideration


Myeong and I teleconferenced for 60 minutes today and discussed the
pros and cons of specifying "medical realism" in the humanoid
animation specification. She asked me to list my ideas for Use Cases
and the estimated customer segment size (at least in the USA).

I think the H-Anim WG has to debate the goals of medical realism via
DICOM imagery (some 51 modality types! 16 have been retired) in the
context of typical realism known in computer graphics-physical, photo
and functional.

I am pondering the implications of introducing "medical realism" into
the H-Anim specification and what that means for H-Anim authors. At
what level (nano, micro, meso and macro) bio-spatially do we set as a
threshold of internal bodily system, tissue, cellular and molecular
definition matching the four-level skeletal articulation in today's
H-Anim specification?  We will solicit the Medial working group
leaders to frame the discussion so we gracefully navigate the
parametric human being over its lifetime and bio-spatial composition.

Use Cases (titles only) by Customer Segment (Authors and Consumers):

High Schoolers (half gross and half fine motor control)

  Animate individual performance on sport team using official contest
times (and/or video footage, body sensors, MoCap, etc.) <6 minutes
  Animate a schoolyard fight between only two students (<4 minutes)
  Animate his/her character in a school play's scene (< 5 minutes)

Undergraduates (some fine motor control)

  Animate assembly of consumer product requiring three or more tools
and the assistance of another person (<15 minutes)
  Animate the operation of a motor vehicle's controls while the
vehicle is in motion (<15 minutes)
  Animate the operation of a human powered vehicle on various surfaces
(<10 minutes)

Graduates (a lot of fine motor control)

  Animate playing a musical instrument during a concert performance (<
15 minutes)
  Animate folding a load of functionally realistic clothes (< 20
minutes)
  Animate hunting wild game (<20 minutes)

Post-Graduates

  Animate four classes of surgical procedures with Bio-CAD and
patients' images (replacement, implantation, ...tetomy and
transplantation) [<60 minutes]
  Animate a job interview for a white collar position (e.g., Chief
Executive Officer of a mid-size corporation) [<30 minutes]
  Animate dying (fratricide, suicide and homicide) [<15 minutes]

Professionals

  Animate long duration spaceflight effects [<180 minutes;
representing 18,000 minutes]
  Animate the bends (scuba diving incident) [<60 minutes]
  Animate drug addiction [<60 minutes]
