digital technologies are leading to significant increases in the number of
books produced that are accessible to readers who are blind, visually impaired
or otherwise print disabled. The emerging DAISY/NISO specification is quickly
becoming the international standard for digital talking books; hundreds of
thousands of titles will be converted to DAISY format over the coming decade (National
Library Service, 2004). However, none of these are expected to include
diagrams, illustrations, figures or graphics of any kind. This limits the types
of books that can be effectively converted to digital talking format. Books
that require access to graphics are especially important in early childhood
(Larsen & Jorgensen, 1989) education, technical training and advanced
studies in math and the sciences, so attention should be paid to developing
good, practical strategies for adding to the next generation of digital talking
Graphics, Inc. has designed, implemented and tested the world’s first
illustrated Digital Talking Book (IDTB), under funding from the National
Institute for Disability and Rehabilitation Research (NJDRR). The CSIJN presentation
will include a discussion of this work, and the first public demonstration of a
new version of Touch the Sun (Once, 2005), a NASA-funded book written by Noreen
Once, that was originally executed in traditional Braille book format. The new
IDTB version of Touch the Sun consists of a set of 12 tactile overlay sheets
designed for use with the Talking Tactile Tablet (TTT), and a program on CD
The sheets include illustrations in raised-line and textured format and a collection of control buttons and data entry tools. A reader places individual sheets on the TTT device, and then presses on parts of the images to hear appropriate, recorded human- voice descriptions of what they are touching. They also use a Main Menu of options, which includes an Index that allows them to scroll through a list of all of the graphical elements contained on a particular sheet, and then choose one to have their finger led to it. They can also place and go to bookmarks, perform text-based searches, and change settings such as speech rate and touch sensitivity.
The presentation will include results of preliminary user testing. Here, ten braille-literate participants were asked to use both the new Illustrated Digital Talking Book version, and then the original braille version of Touch the Sun. Afterward, both groups received the same content examination and picture identification test, to measure relative differences in comprehension, retention and reader satisfaction between the two versions.
One of the system’s developers interacting with the TTT
Based on successful outcomes in this preliminary research, the Company hopes to be awarded follow-on finding, for the purpose of developing a proposal for a modular extension to the official DAISY/NISO Specification (DAISY, 2005), to ensure that tools for including interactive talking tactile graphics in digital talking books are incorporated in the emerging standard. For the purpose of carrying out this complex task, Touch Graphics is teaming up with the Benetech Initiative, an associate member of the DAISY consortium, and the developers of Bookshare.org, a widely used service for producing and distributing DAISY-formatted digital talking books. The long term ambition of this team is to ensure that many categories of books not currently considered appropriate for conversion to accessible format will be produced and made available to visually impaired

SAL2: RECONFIGURING SAL BRAILLE LITERACY COURSEWARE FOR DELIVERY VIA THE ECONOMICAL TALKING TACTILE TABLET
The SAL System for teaching Braille literacy allows students to practice skills introduced by a teacher of the visually impaired. Students work at an individual pace, as they interact
a virtual instructor in carrying out increasingly more challenging tasks and
drills. Now, Exceptional Teaching, Inc. has teamed with Touch Graphics, Inc. to
create a new version of the system that is designed to run on the Talking
Tactile Tablet (TTT). In contrast to the original, stand-alone SAL unit, the
TTT is a computer peripheral device, so it is dramatically less expensive and
has the advantage of being able to be used with a whole collection of other,
existing and future applications, such as the National Geographic Talking
Tactile Atlas of the World, the TTT Authoring Tool and TTT Crossword Puzzles
and TTT Match Game. Also, new features have been added to the SAL courseware in
this latest configuration; these improve the system’s overall power,
effectiveness and ease of use for both teachers and students.
main concepts and the pedagogical approach in the new system replicates the
original SAL Courseware: the student places one of a large number of embossed
paper sheets on the TTT device, and then follows instructions for carrying out
activities, For example, one activity requires the student to press their
finger on any line of Braille on a sheet that begins and ends with the letter
“g”. As the student works, the virtual instructor announces, “right”, “way to
go”, “good job”, or in the event that he or she makes a mistake, “no”, “that’s
not right”, “try again”, etc. Upon completing a sheet, the student presses the
circle button, and gets instant feedback on the total number of correct
responses and amount of time taken to complete the activity. In other
activities, students are asked to read a short story and then answer a series
of multiple choice questions to demonstrate comprehension. As in the letter
identification exercises, the system provides immediate feedback to the student
regarding their performance, thereby enhancing his or her feeling of progress
important new tool that has been added in SAL2 focuses on improving teachers’
ability to review student performance and progress. To use this feature, the
teacher logs in as “teacher”, and then is asked to select one of the SAL2 users
who have worked on that computer. Once the student is selected, a summary
report is displayed (and spoken aloud), in which the teacher is first given an
overview report, which includes total number of activities worked on, most
recent date worked, total number of hours and minutes worked, and the student’s
average percentage of correct responses. For finer grain reports, the teacher
is asked to select a SAL2 title and lesson, to find out results for any
activity on which the student has worked. It is also easy for the teacher to
request a printed report for any student, and this can be saved to that
student’s records for the purpose of an Individual Education Plan (IEP), determining
grades or sending reports to parents.
important innovation that is embodied in SAL2 is a Main Menu that provides a
range of powerful functions and tools. A program logic flow diagram,
illustrating the entire Main Menu structure and features, appears below as
figure 2. A “Library” option permits the student to view a list of all SALZ
materials loaded on the computer, and to find the sheet number for any
activity; once an activity has been selected, the student is coached to remove
the current sheet and replace it with the desired new one. Other features in
the Main Menu include tools for creating and retrieving bookmarks, and a full
range of user settings, including speech rate, volume, voice and touch
sensitivity of the TTT.
