I think we will need to move to a more relative layout strategy. As I mention in the thesis, there is some natural organization of the symbols based on the layout of the body. There is also some natural relationships between symbols such that certain types of symbols only relate to other types of symbols. So, those relationships can also help us in finding ways to organize the symbol relationships in how the layout is encoded. I think that there would be no specific need to mark the location of the first symbol in a sign box. It could be understood to be placed in the center of the sign box. Then everything else is positioned either relative to the previous symbol or relative to the body. There is more detail in the last two chapters that describe some of my preliminary conclusions. At the least, I think we should use polar coordinates rather than cartesian coordinates.
Great! I'm glad they're working together on it. I hope great things come out of the collaboration.
I know I brought this up before but I'm wondering, Stuart, if a concept of relative coordinate systems was discussed in your thesis? I did a quick scan so I'm not sure if it was. What I mean by "relative" is a coordinate system that's related to a previous symbol in a sign according to that sign's signspelling sequence.
The coordinate for the first symbol would be in absolute coordinates according to the signbox, then the second symbol would relate to the first symbol according to a coordinate system using a point of the first symbol as the origin.
Doing it that way may allow establishing matrices of symbol pairing in a sign. I would imagine this to be similar to "kerning" and possibly define distances according to the pairs rotation of not only themselves but to each other. Similar to what you were saying about establishing minimum distances.
About the overlap of symbols that you mention. I was wondering if it couldn't also be solved by a matrix of symbol pairing so that a particular matrix value would indicate overlap - say, a value of -1. On the other hand, do you think it would be possible to create totally different symbols that are overlaps of two symbols? I ask this as that's what's done in other languages when there's an overlap. For instance, "ζ" which looks like "a" and "e" overlapped but is it's own symbol. I would hazard a guess that separate symbols are only possible when there's only a few.

Hello Bill -Just want you to know that we have a group of Unicode-knowledgeable people working together on our SignWriting proposals that will be presented to the Unicode-related meetings over a period of years, and Steve and Stuart are both in the group, along with others as well - so we are all working together...The proposals have been separated into proposing the encoding of the symbols, or characters, first, (of the International SignWriting Alphabet 2010) and then once the symbols have been encoded, we will present a second proposal related to layout and symbol placement issues - so that second area is where different theories will be discussed until we can come up with a final decision for a second proposal - so we are taking this one step at at a time...
An exciting time for all of us - smile -

Wow, that was a lot of work! I do have one question. How would the most recent work in Unicode and, more particularly, what Steve Slevinski has written to the list affect the portion where you talk about what may be needed for successful Unicode acceptance? From what it appears, it's well on it's way to acceptance with what Steve and Michael Everson have done.

For those of you interested in reading it, you can download a PDF from the University website. Just so you know, the PDF itself is about 22MB.
If you have any questions about it, just let me know.
