Touch Graphics, Inc. and Exceptional Teaching Inc. have teamed up to introduce SAL2, next-generation braille literacy courseware that runs on the TTT. Based on Dr. Sally Mangold’s original SAL (Speech Assisted Learning) System, SAL2 is an interactive braille learning station for blind students of all ages. Using the SAL2 System, students can acquire new braille skills and enhance their braille reading and writing. Students place a paper worksheet on the TTT, and then follow simple instructions for using the system, as they practice skills and develop proficiency in concepts introduced by their teacher.

SAL2’s “virtual instructor” provides encouraging audio feedback, as students work their way through the lessons. They work at their own pace, and may repeat lessons as many times as necessary to achieve mastery of the material. The SAL2 System records student performance and provides a teacher report on individual student activities as well as an overview of student progress. Using a “Main Menu”, teachers and students select lessons to work on, place or go to “bookmarks”, or make adjustments to settings, such as speech rate and pitch, volume, and the firmness with which they must touch the TTT to make it respond.
