<p>Hi David</p>
<p> </p>
<p>Thanks a lot for the links.</p>
<p> </p>
<p>About stream package size, we have been discussing it a bit and found that it could be possible to transfere states doing a roughly estimate. Maybee someone would like to help us doing a more accurate estimation of xml based states transfere rate and possible minimum
physical transport layer ( ADSL, Wireless,,, ) to be used. </p>
<p> </p>
<p>Note: </p>
<p>- XMPP uses zlib <a href="http://xmpp.org/extensions/xep-0138.html">http://xmpp.org/extensions/xep-0138.html</a> for compression and an estimate compression ratio are presented in
<a href="http://gnosis.cx/publish/programming/xml_compression.html">http://gnosis.cx/publish/programming/xml_compression.html</a></p>
<p>- XMPP also uses SLL / TSL <a href="http://xmpp.org/extensions/xep-0035.html">
http://xmpp.org/extensions/xep-0035.html</a> to improve security.</p>
<p>and BOSH ( Bidirectional-streams Over Synchronous HTTP ) <a href="http://xmpp.org/extensions/xep-0206.html">

http://www.keyboardmods.com/2010/12/howto-kinect-openninite-skeleton.html</a> could IMHO be usefull to support calculation joint rotation for h-amin. Have to look deeper into this.

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>
<br>
All the best<br>

<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>
Cheers,<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>
Christoph<br>

Open up new possibilities combining kinetik with instant reality AR!<br>
David: you writes about a server can it be a server demon in the same computer that are running Kinetik / OpenNI and 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>

Maybee trough some NetworkSensorNode using some protocol and JScript using libs from

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>

Just some thoughts.<br>
