The study of physics is replete with requirements to create and analyze technical drawings. This is obviously more difficult for blind students than for sighted students. However, blind students can draw technical diagrams and the purpose of this module is to show you how. If you can imagine it, you can draw it using SVG.

Preface
General
This module is part of a collection of modules designed to make physics
concepts accessible to blind students.
If you opened this page in the context of the book, a Table of Contents for

This book is intended to supplement but not to replace the textbook in an
introductory high school or college physics course.
The study of physics is replete with requirements to create and analyze
technical drawings. This is obviously more difficult for blind students than forsighted students. However, blind students can draw technical diagrams and the
purpose of this module is to show you how. If you can imagine it, you can drawit using SVG.
Prerequisites
In addition to an Internet connection and a browser, you will need the
following tools
(as a minimum) to work through the exercises in these modules:
- A graph board for plotting graphs and vector diagrams (
(External Link) ).
- A protractor for measuring angles (
(External Link) ).
- An audio screen reader that is compatible with your operating system,
such as the NonVisual Desktop Access program (NVDA), which is freelyavailable at
(External Link) .
- A refreshable Braille display capable of providing a line by line tactile output of information displayed on the computer monitor
(
(External Link) ).
- A device to create Braille labels. Will be used to label graphs
constructed on the graph board.
- The ability to create tactile graphics as described
here .
The minimum prerequisites for understanding the material in these modules
include:
- A good understanding of algebra.
- An understanding of the use of a graph board for plotting graphs and
vector diagrams (
(External Link) ).
- An understanding of the use of a protractor for measuring angles (
(External Link) ).
- A basic understanding of the use of sine, cosine, and tangent from
trigonometry (
(External Link) ).
- An introductory understanding of JavaScript programming (
(External Link) and
(External Link) ).
- An understanding of all of the material covered in the earlier modules
in this collection.
- An understanding of the creation and use of tactile graphics as
described
here .
