<div><div style="padding:0.5em;line-height:1">May I suggest a few ideas, although I don't know whether they're new, although I will not be able to contribute to their realization?<br>
<br>
1) One should be able to implement custom navigation methods, e.g. by scripting<br>
<br>
2) one should be able to introduce a navigation method (or methods) as an integral part(s) of an avatar<br>
<br>
3) what is an avatar: an avatar consists of one or more dynamic models that represent a virtual identity<br>
<br>
4) a dynamic model is a model that can be loaded or unloaded on demand during the lifetime of a multiuser session <br>
<br>
5) one virtual identity can be related to one or more real identities (users). In the latter case the virtual identity is called a "crew"<br>

I propose a review of X3D navigation methods for the Feb 7 2020 X3D Working Group call. 11:00 AM EST, 8 AM PST, 16:00 UTC
<br>
<br> On Zoom:
<a href="https://zoom.us/j/148206572" target="_blank">https://zoom.us/j/148206572</a>
<br>
<br> Preliminary outline
<br>
<br> 1. Current 'standard' navigation methods, how do implementations differ?
<br> 2. Current extensions, for example the TURNTABLE. Can they be put in spec?
<br> 3. What methods are usable for environments not mouse-driven , for example haptic devices; and mobile touchscreens,
<br>
<br>
<br> All suggestions welcome
