There are google groups for OpenNI <a

and Kinect <a href="http://groups.google.com/group/openkinect">http://groups.google.com/group/openkinect</a><br>
<br>
You can put whatever network protocol you want on it, because there
is none. Because of the amount of data and the speed you want to
move it, I wouldn't wrap it with a verbose language, keep it as
compact (binary) as possible.<br>
<br>
The PrimeSense and Microsoft libraries are basically device drivers,
and OpenNI is an abstraction layer which (in theory) could handle
multiple cameras (including stereo cameras), and audio and all that,
so it would not require a Kinect.<br>
<br>
The NITE component handles the skeletal tracking. So you could map
that stuff to HANIM or whatnot.<br>
<br>
I've used this with Unity and had skeletal tracking to drive an
in-scene avatar working in less than an hour. Drag and drop
simplicity. But that's Unity.<br>

<div>Hi Lauren<br>
<br>
Completely agree.<br>
<br>
I should have better matched the "Network Sensor" with the
"socket interface". Both have nothing to do with the
actually used network and transport protocols.<br>
<br>
Regarding the MU Server topic, I'd historically match MU
Servers with the different Networks (Ethernet, Token Ring,
.......), where the network sensor + protocol tbd. would
historically match to socket interface + TCP/IP.<br>
<br>
However, I'm no prophet, so future will show, if this
comparison will have been valid :-)<br>
<br>
Thanks<br>
Christoph<br>

Christoph, <br>
<br>
You were asking "how far?". And, IOW, my answer was
'that-is-how-far for MU UI standards, but why'. I wanted
to help explore what it is you had in mind because I found
it intriguing.<br>
<br>
>...if the pilot avatar has some properties that
mandate to "run" the pilot avatar in a given instance.<br>
<br>
I did not mean to completely hijack this thread but, isn't
that exactly was MU servers are for? If the avatar is in a
different instance then that avatar is no longer pilot,
right? You are talking about a MU client-server
relationship and that is just what they (the MU servers)
help do. Or do I not understand your point correctly?<br>
<br>
Likewise, tcp/ip can, like other protocols, be used in the
context of a network sensor implementation, or any MU
network for that matter (Network Sensor is only a name for
a set of agreed-upon implementation parameters and
methods. Just another link in the network chain. In and by
itself doesn't really do anything. But I digress). <br>
<br>

Hello Lauren<br>
<br>
Thanks for your answers.<br>
<br>
ad "Interesting questions. What do you have in mind?":<br>
In his original answer, Dave wrote: "you would need it
running a server,<br>
which may be localhost". I'm just thinking the next step:
What, if is NOT localhost?<br>
Could have impacts on performance. And what, if the pilot
avatar has some <br>
properties that mandate to "run" the pilot avatar in a
given instance?<br>
<br>
2- X3D is the best example that standardization needs not
necessarily preclude innovation,<br>
as long as the standard is flexible and extensible enough.<br>
However, it's always an art of timing (doing it not too
early and not too late).<br>
<br>
3 - regarding DIS, I'd like to be "blind on that eye" :-)<br>
You know, I'm comparing the network sensor with TCP/IP
(regarding its<br>
historical relevance)<br>

All the best<br>

Hello Christoph,<br>
<br>
Interesting questions. What do you have in mind? Let me
try to answer. <br>
<br>
1- Perhaps in a third party view, but then the second
browser instance would be controlling the pilot (if there
is/was such an impmentation). So what's the difference? I
am not sure what you are asking exactly.
<br>
<br>
2- Good question perhaps. But do we really want avatar
user-interface standardization? If you look at the game
industry for example, innovations is a driving factor.
Wouldn't standardization impede innovation in that regard?<br>
<br>
3- I think you may want to look into Distributed
Interactive Simulation (DIS) and even Living Worlds for an
historical perspective if you haven't (but I suspect you
have). There have been some implementation efforts of
these and other proposals, but MU user-interface
standards??? I would refer back to question #2. <br>
<br>
4- You can download Avatar Studio 2 and patch files at
officetowers.com (click My Avatar).<br>
<br>

Hi<br>
<br>
Some additional questions/thoughts............<br>
<br>
Opinion: The following sentence is true for any Web3D
browser and any<br>
multiuser system:<br>
In any X3D/VRML multiuser session with M users and N
instances of a<br>
Web3D browser, each (pilot) user controls one pilot avatar
and N-1 follower avatars.<br>
<br>
Question#1: Can we think of situations, where the pilot
avatar and the user do<br>
not share the same instance of the Web3D Browser, but use
different instances?<br>
<br>
Question#2: How far is the interface between user and his
pilot avatar<br>
standardized? Do exist de facto standards?<br>
<br>
Question#3: How far is the interface between pilot avatar
and his followers<br>
standardized? Do exist de facto standards?<br>
<br>
Question#4: Could anybody recommend authoring tools for
X3D/VRML avatars?<br>
(pricing according to hobby use cases, it should be
flexible and<br>
extensible, fitting to any Web3D browser, best would be
open source)<br>
<br>
Thanks for your help........<br>
<br>

a X3D browser or application?<br>

I think you would need it running a server, which may be
localhost, and talk to that via Ajax or network sensor. Of
course if a browser can be extended via DLL, that browser
could talk directly to the Kinect, but if you want it
multi-platform, local server is the most generic.<br>
OpenNI includes hand tracking. Not sure where they are
with finger tracking yet. <br>
OpenCV and OpenNI have been used together for extra
tracking goodness.<br>

<br>
Maybee trough some NetworkSensorNode using some protocol
and JScript using libs from <a class="moz-txt-link-freetext" href="http://strophe.im/">http://strophe.im/</a>, or a C++
based X3Dbrowser but then it's limited to that browser.<br>
This will give body gesture control, could it be possible
to add OpenCV based code to add hand/finger control.<br>
And can we use "brain position feedback control" to on the
fly calibrate positions and will it introduse brain
fatigue.<br>
<br>
Just some thoughts.<br>
