The Development of a Tool to Enhance Communications Between Blind and Sighted Mathematicians, Students, and Teachers: A global Translation Appliance. University of South Florida (H133G010046) led by Arthur I. Karshmer, PhD. Richard Johnson, EdD, Project Officer.
Abstract: This project builds a translator for several mark-up notations used in scientific, mathematic, engineering, and technological fields. The primary difficulty encountered by students with visual impairments in pursuing studies in science, mathematics, engineering, or technology is how to read and write mathematics. The new tool allows free conversion among the several codes by developing a common intermediate format (CIF) for representing mathematics, and uses logic programming and denotational semantics to translate between supported notations and the CIF. The CIF is also used to develop a mark-up notation independent auditory browser for the understanding of complex mathematical expressions by users with visual impairments.

New Research: Selections from REHABDATA

Warnecke, P. (2003) A caregiver's eye on elders with low vision. Caring, 22(1), 12-15. Accession Number: J44893.
Abstract: Article discusses how home health providers and other caregivers can help older adults with low vision continue to function at their maximal level. Adaptive devices and strategies for enlarging an item, controlling lighting effectively, enhancing the contrast of objects, and the use of non-optical devices are discussed.

Sforza, C., Eid, L., Michielon, G., Fragnto, N., Ferrario, V.F. (2003) Sensorial afferentes, expectations, and craniocervical postural relations in adults who are blind and sighted. Journal of Visual Impairment and Blindness, 97(1), 17-27. Accession Number: J44912.
Abstract: Study examines the impact of different internal and external influences on the normal head and neck positions in adults who are blind and sighted. Data were obtained while the subjects maintained four positions: rest, centric occlusion, mirror, and sound. Results showed that at rest, blind subjects have more flexed necks and heads than do sighted subjects. The centric occlusion position was accompanied by head extension in both groups, neck extension in the blind subjects, and neck flexion in the sighted subjects. In the mirror trial, blind subjects extended their necks, but no modifications were observed for the sighted subjects. In the sound trial, both groups flexed their necks.

Moore, J.E. (2003) Using program evaluation to improve service delivery for older individuals who are blind. Journal of Visual Impairment and Blindness, 97(1), 42-45. Accession Number: J44915.
Abstract: Author uses results from ongoing evaluations to offer suggestions for improving independent living programs delivery for older adults who are blind. Recommendations regarding service delivery, policies and procedures, staff training, fiscal policies, and audit issues are offered.

Zebehazy, K., Whitten, E. (2003) Collaborating between special schools and local education agencies: A progress report. Journal of Visual Impairment and Blindness, 97(2), 73-84. Accession Number: J44916.
Abstract: Paper describes the types of service offered by schools for students who are visually impaired (special schools) to students in local education agencies (LEAs). A survey was conducted to determine the level of collaboration between special schools and LEAs and the problems that need to be addressed to increase the effectiveness of services. Most of the schools reported serving equally as special schools and as outrech service providers to LEAs. The mjaority of respondents thought that collaboration and follow-up are important and considered their current level of collaboration with LEAs to be good. Areas for improvement included the need for better follow-ups, better understanding by LEAs of services offered by special schools, less territorialism in servicing students, more in person contacts, and better resource sharing.
