Abstract for Tactile Graphics 2008

Title: Update on automatic tactile graphics

Reference: P4-B

Presenter: Dan Comden

University of Washington, USA

Abstract:

Traditional creation of tactile graphics is a time consuming and laborious process. Delivering images from textbooks to blind students has meant hours of editing and creating Braille labels for print text. The Tactile Graphics Project at the University of Washington has created software called the Tactile Graphics Assistant (TGA) to greatly speed this process, achieving per-image processing rates under five minutes. This presentation will discuss the TGA software and related applications used to prepare groups of individual graphics for batch processing. Text extraction of labels will be demonstrated and the work flow will be shown. The TGA software is available via a free license from the project web site: http://tactilegraphics.cs.washington.edu/

Objectives of presentation:

Demonstrate batch processing of tactile graphics
Provide web-based resources for tactile graphics creators
Demonstrate completed graphics sets for textbooks

Outcomes for audience:

Understand current and proposed tactile graphics production.
Witness the TGA software working with a variety of image types.
Learn how textbook images can be shared with other users.
