The visual nature of STEM academic subjects presents challenges to students with visual impairments (VI), their instructors, and the developers of educational materials. Three dimensional models and scientific devices are available for typical students but only some of these products are suitable for students with VI, and others are accessible only with appropriate adaptations. APH strives to fill this gap in a variety of ways. Ground-up product design shaped three interactive models that demonstrate DNA structure and function including semiconservative DNA replication, messenger RNA (mRNA) transcription, and mRNA translation to polypeptides and proteins. Collaboration between APH and Orbit Research produced the Orion Ti84 Plus Talking Graphic Calculator, the first fully accessible handheld device of its kind. Adjustable synthesized speech, haptic feedback, and sonified graphics convey information to the student with VI, along with the ability to print and emboss graphics.
