0.3 Phy1006: a small-scale demonstration of the iveo learning  (Page 5/7)

Ask your assistant to start the Inkscape program and to open a copy of the file named Svg23.svg in that program.

• Press Ctrl+Alt+A to prepare the image for a horizontal flip. Your assistant should see a bunch of little arrows on the screenindicating that all of the objects in the image have been selected.
• Pull down the Object menu and select Flip Horizontal . Your assistant should see the image flipped from its normal state to a mirror image of its normal state.
• Press Ctrl+P to cause the flipped image to be printed.
• Press Ctrl+Q to quit. When the opportunity presents itself, click the button labeled Close without saving ..

The printed output

Your assistant should see the mirror image of an image that is very similar to Figure 1 . However, the overall size of the image will be different from Figure 1 due to the differing sizes of our respective tablets.

All of the shapes in the image should be contained inside a rectangle that is very close tothe size of the active area on your tablet. If that is not the case, something is wrong and you will need to backtrack and fix the problem.

Manually emboss the image

Ask your assistant to use a tracing wheel or something similar to manually emboss the printed mirror image. Ask him or her to try to emboss the heavy linesas double lines to make them easier for you to locate and identify with your fingers.

A text block

There will be some text in the upper-right corner of the mirror image. It won't be necessary toemboss the characters in that text. Simply emboss some marks that will alert you to the location of the text.

A pseudo-text marker

There is also a small circle underneath the triangle. (Depending on the size of your digitizer tablet, the circle may actually appear on top of the triangle.) Once again, it won't be necessary to emboss that circle as a circle. Simply embossan X there so that you will be able to discern the location of that circle. (This is the pseudo-text marker that I referred to earlier . I will explain its purpose later.)

Attach the image to the digitizer tablet

Once the image has been embossed, trim the image very carefully at the rectangular border. Using masking tape or something similar turn the image over with the inkside down and affix it to the active area of your tablet. Be very careful because proper alignment is critical at this point.

Ask your assistant to somehow mark the upper-left and lower-right corners of the rectangle so that youcan discern them later when times comes to calibrate the touchpad.

Load the SVG file into the IVEO Viewer

Start the IVEO Viewer program running. When it is running and ready for action, you should hear awelcome message.

Open the SVG file

Press Ctrl+O to open the SVG file. Navigate the disk and open the file named Svg23.svg . When the file opens in IVEO, you should hear something like the following:

"Document title description of the document"

The page setup operation

Open the File menu and select the item named Page Setup .

Select Letter (Landscape) if your rectangle is wider than it is tall. Select Letter (Portrait) if your rectangle is taller than it is wide.
