[Blindmath] a freehand drawing idea for SVG draw 01

[Sarah Jevnikar]

This would be neat, but I can see the difficulties in actually drawing a
graph. It'd certainly help with economics curves though.

Hi all,

Does anyone fancy a freehand drawing mode?  The advantage of this mode would
be that you would no longer have to remember coordinates.  One of the
biggest problems in drawing anything at the moment is that once your diagram
becomes sufficiently large, it is difficult to remember all the coordinates.
The freehand drawing mode may eliminate this problem.  The way this mode
would work is as follows.
1.  Once you activate freehand drawing mode, your mouse would get stuck in
the drawing window.

2.  If you hold down the left mouse button, and move the mouse, you would be
drawing something on the screen.  The mouse movements would be captured as
screen coordinates and converted to SVG coordinates..

3.  Once you release the left mouse button, you will be prompted to enter a
description for the shape and the coordinates that have drawn would be
shown.

4.  If you would drawing a SVG primitive element such as an ellipse, you
would have a wizard interface where you would need to touch the different
parts of the shape.  For example, the first step in drawing an ellipse would
be to touch the centre of the ellipse.  You could then be prompted to touch
the X and Y coordinates of the arc.

As regards tracking where I am when drawing, the first version of this
feature would speak the screen coordinates as you draw so, you have an idea
of where you're going.  It is indeed possible to create a sound
representation of this path but for maximum accuracy, let us have a speaking
of the coordinates.

Pranav.
