THE PROLIFERATION OF GRAPHICAL USER INTERFACES (GUIS) IN PERSONAL COMPUTERS, SUCH AS MICROSOFT WINDOWS AND MACINTOSH, IS A THREAT TO VISUALLY IMPAIRED PERSONS' ABILITY TO USE COMPUTERS BECAUSE GUIS REPRESENT INFORMATION ICONICLY AND SPATIALLY, AS WELL AS TEXTUALLY. THE GUIS VISUAL ORIENTATION MAKES GUIS DIFFICULT FOR THE VISUALLY IMPAIRED TO ACCESS THROUGH TRADITIONAL ASSISTIVE TECHNOLOGIES. WE PR ...

This research will explore the use of a virtual polyhedron modeling environment which creates nets, or patterns, for a polyhedron created on the screen, in the teaching of geometry and spatial skills. When the net is printed, cut, folded, and glued together, a 3-dimensional model of the original polyhedron is created. We propose to examine the use of this tool in an instructional setting, to dete ...

The goal of this project is to improve remedial math instruction for adults by combining (a) an effective adult education model; (b) an effective instructional design method, with; (c) the multimedia capabilities of the computer. The innovative combination of these components will produce an effective math program designed specifically for adult learners that can be used at home, at school, or ...

THIS PROPOSAL ADDRESSES THE POSSIBILITY OF UTILIZING COMMERCIALLY-AVAILABLE LETTER-QUALITY OR DOT-MATRIX PRINTERSFOR BRAILLE OUTPUT WHEN USED WITH A MICROCOMPUTER. THE BRAILLE-OUTPUT ENVISIONED WOULD BE GRADE I BRABRAILLE SINCE GRADE II WOULD NORMALLY REQUIRE TRANSCRIPTION BY AN EX AN EXPERIENCED BRAILLIST. THIS CONCEPT IS INTENDED TO PROVIDE AN INEXPENSIVE, AUTOMATED, AND RAPID SYSTEM OF BRAILLE- ...

A PROGRAM IS PROPOSED TO EVALUATE THE IMPACT OF CHANNELING OF OXYGEN ON BURIED OXIDE XNTEGRITY IN SIMOX MATERIAL. BURIED OXIDE PINHOLEDENSITY AND CRYSTALLOGRAPHIC ORIENTATION RELATED PATTERNS IN BURIED OXIDE PINHOLE MAPS WILL BE EXPLAINED DEPENDING UPON THE IMPLANT ANGLE. THE METHOD BASED ON THE ELECTROYTIC PLATING OF COPPER WILL BE USED TO OBTAIN THE MAPS OF PINHOLES. THIS WORK WILL IMPROVE KNOWL ...

SIMOX (Separation by IMplanted Oxygen) technology achieves total dielelectric isolation of active device regions from the substrate and reduces the collection path for ionized charges via the built-in buried oxide which restricts charge movement. Advances in SIMOX technology include radiation hardened memories and gate arrays for space applications, ULSI DRAMS for low voltage operation, thin film ...

RECENT ADVANCES IN MICROCOMPUTER TECHNOLOGY HAVE MADE IT POSSIBLE FOR VISUALLY IMPAIRED PERSONS TO CONTINUE NORMALLY WITH THEIR EDUCATION. VOICE SYNTHESIZERS AND TEXT MAGNIFI CATION ENABLE HANDICAPPED INDIVIDUALS TO BEAR RO READ BOOKS,MAGAZINES, AND OTHER PUBLICATIONS WHICH ARE STORED IN D N DIGITAL FROM IN THE MICROCOMPUTER. THE RECENT INTRODUCTION OF A LOW COST, MANUALLY OPERATED, OPTICAL SCANNE ...

Today's extremely powerful, low-cost computer systems offer tremendous potential as learning tools. However, development of high quality educational software, particularly simulations, lags behind. This research will explore the issues in creating highly realistic, very detailed simulations directly targeted for educational purposes. The domain simulated will be a small retail business. This do ...

Lexitek proposes to develop an imaging gamma-ray detector with 1024 x 1024 pixels for arms control verification. The proposed detector significantly enhances the resolution of fissionable material distribution without compromising energy resolution. The detector consists of a scintillating crystal and associated sensors which determine the energy and position of the scintillation with high spat ...

This proposal describes an effort to improve the education of at-risk youth through web-publishable, project-based activities. These activities might include electronic journalism on community issues, natural science projects, or digital art Galleries. Activities such as these are particularly appropriate for at-risk youth through their power to integrate school and home or street life, to give ...
