Then click the OK button.

You may be asked "Do you want to fit the image to the new page size?" If so, click the Yes button.

Calibrate the touchpad

Press Ctrl+U to calibrate the touchpad to your image.

You will be asked to "Touch top left corner of the image."

At this point, you should touch the top left cornerof the image that is taped onto your tablet. Follow the verbal instruction and press the space bar to confirm.

You will then be asked to "Touch bottom right corner of the image." Touch the bottom right corner of the image that is taped onto your tablet, and press the space bar to confirm.

You should hear "calibration finished."

Explore the image with your fingers

You are now ready to begin the exploration of the image using your fingers, or a combination of your fingers and a stylus depending on the kind of tabletthat you are using.

Touch the text object

If you touch the area near the upper-left corner that your assistant has identified ascontaining text, you should hear "This is a text object." If you are interested in doing so, you can locate the code in Listing 2 responsible for this behavior by searching that listing for the matching text.

Touch the circle

Touch anywhere inside the circle in the left half of your image and youshould hear "Circle."

Then press Ctrl+d and you should hear "Circle Description of the circle."

In other words, once you touch one of the objects and hear a voice that identifies the object, you can press Ctrl+d to hear more information about the object.

Once again, if you are interested in doing so, you can search for this text in the Java code in Listing 2 and see the code that is responsible for this behavior.

Touch the triangle

If you touch anywhere inside the triangle in the right half of your image, youshould hear "Triangle." Pressing Ctrl+d at that point will provide additionalinformation about the triangle.

Touch the pseudo-text marker

If you touch the marker underneath (or perhaps on) the triangle, you should hear "This is pseudo text identified by a text marker."

This is an alternative to actually putting text in the drawing as was done above . This approach can be used to include text in the drawing without allowing the text tocause the drawing to become messy. It is useful when there is a lot text that needs to be included in the drawing. It is also useful when two ordinary textobjects would overlap.

The downside is that a sighted teacher or a low-vision student can't see the text. It only becomes exposed when the SVG file is processed using the IVEO system .

Touch the line

Try to touch the line that extends from the lower left to the upper right corner of the rectangle. This cansometimes be difficult, particularly if the printed and embossed version of the drawing isn't well registered on the touchpad.
