Improving Access to Graphical Images for the Blind Project Overview The Tactile Graphics Project aims to increase universal benefit from graphical images (i.e., line graphs, bar charts, illustrations, etc.). It is a multidisciplinary project with researchers and practitioners from UW's Department of Computer Science and Engineering, Access Technology Lab, and DO-IT. Our goal is to enable K-12, college, undergrad, and graduates students who are blind to have full access to mathematics, engineering, and science. We have developed the Tactile Graphics Assistant which, when combined with off-the-shelf software applications, enables the rapid translation of visual graphics to a tactile form. Research includes: Developing machine learning algorithms that can easily classify images for processing Developing image segmentation algorithms that can extract textual labels in graphical images Developing algorithms to effectively place Braille text Developing a tool (the Tactile Graphics Assistant) to facilitate automated tactilization of graphical images Developing a workflow to efficiently translate visual images to a tactile form Developing resources to assist in transcriber training Download Tactile Graphics Assistant To download the Tactile Graphic Assistant please go to TGA Registration and Download. Once registration is completed, you will be sent e-mail containing the download site. Registration will enable us to let you know when updates to the software become available. Please note that version 2.4 of the TGA is available as of 8/15/2007. If you have an older version, please download again through the registration site, so we can keep track of which version you have.
