[Blindmath] requesting for procedure regarding svg draw.

Dear Baldwin,

It is an excellent understanding of the device just as you have described.
Most of the information is right, the grid of tactile plungers are not just
the picture of the dots, they indeed work in enabling a user use them to
input various shapes in to a desired application. There are five rows of
different standard shapes and visual objects such as the bar charts and the
pie charts, some functions for the mathematical symbols etc, apart from the
standard shapes in first two rows of control panel.

There are numeric keys 0-9 on the fourth row that are helpful in numerical
substitution in the software. There are other standard buttons in the bottom
row that are for the other standard functions like the delete, space bar,
page up, page down, back space and a 4 way navigation keys for  up down left
right actions.

In short they are all put up to be used for all the functionality of the
device. I have come out with the device after analysing a few things with
regards to the visual presentation requirements that a VI person may have,
and hence i have put up as many things as possible for the use in this
device.

I have a small query, does the combination of any of the available
technologies enable a visually impaired person to make a doc file or a power
point presentation slide, with some shapes in it? Can you insert the shape
of an ellipse in a word file? Can a person like raju singh, who is studying
the computer application degree course use screen reader and draw a entire
flow chart in a visio environment? We certainly have programs that can help
us in making the shapes in SVG format but can we import them in a slide of
power point and make a presentation? 

on a separate subject i shall introduce the functionalities in depth. 

Kind regards,

Kiran

Amanda,

The picture of the device looks like a smart phone or a tablet computer
running an application. However, the description that was given in the email
message indicates that it is probably a custom physical device, or at least
some kind of a device that has a tactile surface instead of a screen.

The rectangular working area (screen) is roughly divided into two halves.
The left half is mostly occupied by a rectangular grid of dots. There are
perhaps 20 dots on the vertical and 40 dots on the horizontal. They may
actually be popup pins like in your usb Braille device, or they may simply
be pictures of dots.

The right half of the screen contains an array of buttons or pictures of
buttons. This area is divided vertically into three sub-areas.

The top sub-area contains three rows of buttons having different shapes. It
looks like the top row contains a rectangle, a square, a circle, a line, and
a triangle.

The shapes on the second row are a little hard to make out. It looks like
they may be 2D projections of a couple of boxes 3D boxes with different
dimensions, a couple of pyramids with different dimensions, and a sphere.

I can't make out the shapes in the third row. One looks a little like the
symbol for a bar graph, so they may all represent graphs.

The next sub area going down is divided into two areas. The left area
contains two rows of five round buttons. I can't be sure, but I suspect they
are simply the buttons on a numeric keypad. To the right of that are four
buttons with arrows on the face.

All of the buttons described so far are blue-green in color.

The bottom row of five buttons is red. Going from left to right, they look
like a rectangle, an up-arrow, a down-arrow, another rectangle that is wider
and shorter than the first, and a left-arrow that may have a hook on the
right end.

Many of the buttons appear to have some text printed below the button, but
it isn't legible in the picture.

Parentheses appear to be drawn on the ends of the rows of buttons. These
parentheses appear on the first, second, third, and sixth rows of buttons.
The fourth and fifth rows of buttons are grouped in a single pair of
parentheses.

There is something along the bottom of the screen that looks  like the space
bar on a standard keyboard, but it may just be a picture. About one-third of
the way from the left end, there are four parallel diagonal lines drawn on
the bar with the top of each line closer to the left end of the bar. The
line on the left is dark blue. The line on the right is red.
The two lines in the middle are light blue.

There is some text in the upper and lower corners of the screen that looks
like it may simply be a labels but I can't read it.

I was unable to find anything on the website that explains how the device
works or how the user actually uses it.

The website also list several other devices for blind and VI users.
