0.3 Phy1006: a small-scale demonstration of the iveo learning  (Page 4/7)

Some text shows in the upper-left corner of the drawing.

There is a small circle below the triangle, which I will refer to as a pseudo-text marker . I will explain the purpose of the pseudo-text marker later.

Although the dimensions of your digitizer tablet will probably be different than mine, the overall layout of the shapes in your SVG file should bevery similar to mine.

Instructions

In this section, I will provide instructions and explain the steps that you and your assistant will need to take in order to create your own small-scaledemonstration of the IVEO System .

Acquire a USB digitizer tablet

I put this instruction at the beginning of the list because without a USB digitizer tablet (or something to suitably replace the touchpad) , there can be no demonstration. Assuming that you don't have such a tablet, you should check with your friends, take a look on Ebay, etc.

(I will point out, however, that if you have low vision but can still see the computer screen and can use a mouse, you may be able to create this demonstrationwithout the need for a digitizer tablet.)

The brand and size of the tablet isn't terribly important, although the larger the tablet, the closer your small-scale demonstration will come torepresenting the real thing.

It is critical that the tablet connects to the computer via a USB port. It is also critical that the operation of the tabletemulates a mouse. By this, I mean that when you touch the tactile image on the tablet in a given location, the effect must be the same as if you were to use a mouse and click the corresponding location on the image on the screen.

Some tablets work only with a stylus, some work from either a finger touch or a stylus, and possibly some only work from a finger touch. Once again,this isn't too important, but the use of a tablet that works from a finger touch will be closer to the real thing than one that requires a stylus. (Mine requires a stylus.)

Create the SVG file

Once you have acquired your digitizer tablet and you know the dimensions of the active area on your tablet, it is time to create an SVG file that you canuse for testing.

Copy the Java code from Listing 2 into a text file with the name Svg23.java . Make the changes shown in Figure 1 to replace the dimensions of my tablet with the dimensions of your tablet. Note that dimensions are in inches.

Copy the text from Listing 3 into a text file with the name Svg23.bat .

Using the two files listed above, along with the instructions in the module titled If You Can Imagine T, You Can Draw It using SVG , and Listing 26 here ) , compile and run the program named Svg23.java , producing an output file named Svg23.svg .

Install Inkscape

This would be a good time for you to download and install the Inkscape program. You will be needing it shortly so that your assistant can

• create a mirror image of the image in the SVG file, and
• print the mirror image for manual embossing.
