Education, Teaching Aid and Training Content Design Tactilelink Tactile Graphic Education System by Nuoran Chen Tactilelink is a tactile graphic education system for blind and visually impaired students. Traditional hand over hand instruction limits student independence and depends on a scarce number of specialist teachers. Tactilelink combines a 3D printed tablet frame, raised line graphics of circuit diagrams and cross platform software. Sonification guides each student to a target component, as the pitch and intensity of the sound change with finger distance. Instructors can follow several students at once and prepare audio annotations for independent review after class.
