Abstract: The new ViewPlus Ink Pro Embosser permits users to emboss documents and overprint them with black ink. The new ViewPlus EmPrint produces a high-resolution color embossed image. Both printers employ HP ink jets, and both use Viewplus’s patented Tiger embossing technology. Both have a number of user options, including the ability to print original […]

New Technologies for Accessible Tactile Math and Accessible Graphics

Tactile Spatial Math Sighted scientists use two-dimensional math equations, because they provide the most intuitive way to represent the math. Any equation can also be written in a linear form, eg LaTeX code, Fortran, BASIC, and C computer codes. Although often more space-efficient than 2D equations, linear equations become very cumbersome for even moderately complex […]

The ViewPlus IVEO Scalable Vector Graphics Technology for Universally Usable Complex Information

Abstract The new ViewPlus IVEO Creator computer application enables authors easily to make graphical information in Scalable Vector Graphic (SVG) format with features permitting universal accessibility. Simple graphics can be authored in IVEO Creator, but its greatest power is its ability to import almost any format computer file and easily convert to SVG with necessary […]

Braille, Innovations, and Over-Specified Standards

Abstract The new Tiger embossing technology, developed in the author’s research group, produces more readable Braille than conventional embossers. The better readability traces to a smaller diameter embossed dot than that made by conventional technology. Some sighted Braille experts initially leveled criticism at the new technology on the grounds that this dot diameter is smaller […]


Abstract This panel session discusses new approaches to making mathematical expressions accessible to computer users with print-disabilities. The panel members focus on three software products: WinTriangle[6], ChattyInfty[9], and MathPlayer[4]. All three are accessible presently in audio, and all either have or will soon have Braille access. The panel will also present background information and related […]

Scientific Diagrams Made Easy with IVEO™

Abstract: Virtually all modern scientific documents and textbooks use graphical illustrations and/or data displays. The ViewPlus IVEO™ technology, based on Scalable Vector Graphics (SVG) is being developed to permit scientists to publish such graphics in a form fully usable by all people. The first release of IVEO™ was designed to make simple graphics accessible. Development […]
