Tactile graphics, sometimes referred to as the haptic sensory modality, deliver information through touch. They often accompany Braille textbooks to convey content in maps, charts, building layouts, schematic diagrams, and images of geometric figures. Tactile graphics are often handmade by Braille transcribers as part of Braille textbook production. In some cases, the creation of tactile graphics is facilitated by automated processes using various software applications. Some methods used to create tactile graphics are described below.
