- **Description:** Nyctography is a form of substitution cipher writing created by Lewis Carroll in 1891. It is written with a nyctograph (a device invented by Carroll) and uses a system of dots and strokes all based on a dot placed in the upper left corner. Using the Nyctograph, one could quickly jot down ideas or notes without the aid of light. Carroll invented the Nyctograph and Nyctography as he was often awakened during the night with thoughts that needed to be written down at once, and didn't want to go through the lengthy process of lighting a lamp only to have to then extinguish it. The device consisted of a gridded card with sixteen square holes, each a quarter inch wide, and a system of symbols representing an alphabet of Carroll's design, which could then be transcribed the following day. Each character had a large dot or circle in the upper-left corner, and the system included 26 letters plus additional characters for 'and', 'the', digits, letters, and dates. Carroll initially named it "typhlograph" (from typhlos, "blind") but changed it to "Nyctograph" (from nyctos, "night") at the suggestion of one of his brother-students.

## Ancient and Historical Tactile Systems

### [Didymus the Blind's Carved Wooden Letters](https://en.wikipedia.org/wiki/Didymus_the_Blind)
- **Inventor/Developer:** [Didymus the Blind](https://en.wikipedia.org/wiki/Didymus_the_Blind)
- **Origin:** Alexandria, Egypt
- **Date:** 4th Century CE (c. 313-398 CE)
- **Description:** Didymus the Blind began his education by using a system which was remarkably like Braille, that is reading letters engraved into the surface of wood by touch and subsequently furthering his knowledge by listening. Despite his blindness, Didymus excelled in scholarship because of his incredible memory. He found ways to help blind people to read, experimenting with carved wooden letters similar to Braille systems used by the blind today. This represents the earliest documented individual tactile reading system—predating Braille by approximately 1,500 years. Didymus, blinded by ophthalmia at age four, became one of the most learned theologians of his era and taught Saint Jerome.
- **Status:** Historical

### [Japanese Anma/Amma Tradition](https://en.wikipedia.org/wiki/Anma)
- **Origin:** Japan
- **Date:** 1600s–Present
- **Description:** [Anma](https://en.wikipedia.org/wiki/Anma) is a practice of traditional Japanese massage. During the Tokugawa period, edicts were passed which made the practice of anma solely the preserve of the blind—sighted people were prohibited from practicing the art. Blind practitioners dominated anma due to the tactile nature of the techniques, which relied on heightened sensitivity to bodily cues rather than sight. In contemporary Japan, anma continues to underpin vocational training and employment for the visually impaired, with specialized curricula integrated into schools for the blind since the Meiji era's establishment of such institutions in the 1870s. This represents a unique case where tactile expertise became legally exclusive to blind practitioners, transforming heightened tactile sensitivity into professional advantage and creating an entire occupational identity around blindness.

### [Quipu / Khipu](https://en.wikipedia.org/wiki/Quipu)
- **Origin / Users:** Andean Civilizations
- **Date:** 2600 BCE–present
- **Description:** It is generally thought that the system did not include phonetic symbols analogous to letters of the alphabet. However, Gary Urton has suggested that the quipus used a binary system which could record phonological or logographic data. Another theory is that this is at least partially a tactile writing system, as fibers used in Quipu can be differentiated by touch. Quipu could record dates, statistics, accounts, and even abstract ideas. Quipu are still used today across South America. According to Guaman Poma, quipucamayocs could "read" the quipus with their eyes closed. Recent research has found that some quipus are special. Because they're logosyllabic. Meaning the knots and the differences in fibers corresponded to phonetic sounds, which formed words

The drawings function as a multifaceted communication system encoding ritual knowledge, stories, cosmological information, kinship relationships, and agricultural calendars. Each design is executed as a single continuous line without lifting the finger, requiring precise haptic memory and spatial reasoning. The drawings are inherently tactile — created by finger-in-medium and perceptible by tracing the grooves left behind. Over 150 distinct patterns have been documented across different islands, each carrying specific semantic content

It consists of a stone, clay, or wooden board with compartments or grid cells into which counting tokens (seeds, pebbles, or maize kernels) are placed. The arrangement and manipulation of tokens by touch enabled arithmetic operations. Chroniclers including Guaman Poma depicted yupana use alongside quipu.
