Re: definition of "fixed spatial layout

Hi Jim,

Thank you, this has been on my to-do list too long!

I do wonder if there is a better word than “fixed”, but got stuck with that. Perhaps “where a specific spatial layout is necessary…”?

I’d also like to squeeze in editing layouts where you have to see the toolbars and the content at the same time. It goes along with the data-table example fairly well.

I’d probably drop the canvas element as too technology-specific, the content of the canvas would be images, video etc, so it is essentially covered by those I think.

So the examples could be:
“Examples include images, maps, diagrams, video, games, data tables, and interfaces where it is necessary to keep toolbars in view whilst manipulating content.”

Does that make sense? We could extend the exampels to bullet points if it gets weightier.

Cheers,

-Alastair

issue 77 Resize Content
Content can be resized to 400% without loss of content or functionality, and without requiring scrolling in the direction of text except for parts of the content where fixed spatial layout is necessary to use or meaning.

Thinking and scribbling...

fixed spatial layout - elements where the 2 dimensional arrangement of content is necessary for use and/or perceiving relationships. Examples include: images, maps, diagrams, video, data tables, games, <canvas>

Seems too simple. Does it need to be more complicated? The examples - images, maps, diagrams, video, games... and perhaps <canvas>, are generally objects that have a fixed arrangement and can't be reflowed. They can be resized but not rearranged. Tables, it seems, are a special case.  Some (simple ones?) can be rearranged and still retain meaning. The reflow of more complex tables would present difficulties for users trying to discern relationships between cells.
