Braille vs Pictogram System
点字 / 案内用ピクトグラム
Braille comes from Symbol Systems and Pictogram System from Information Design. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.
Braille
A tactile writing system Louis Braille designed at fifteen, giving every letter a two-by-three cell of dots. Sizing that cell to a single fingertip is a rare case of ergonomics and typography arriving at the same answer.
Pictogram System
Unified symbol systems that name facilities and actions without language. Tokyo 1964 systematized sport and wayfinding symbols; the AIGA/DOT transportation set became the public-domain world standard.
| Braille | Pictogram System | |
|---|---|---|
| Era | 1824– | 1964– |
| Family | Symbol Systems | Information Design |
| Kind | Style | Style |
| Cues | The 2x3 dot cell / Dimensions fit to the fingertip / Left-to-right tactile reading / The materiality of embossing | Geometrized human figures / Uniform stroke weight / Consistency as a system / Independence from language |
| Best used for | Adding touch readable text beside signage and wayfinding panels · Giving print or packaging an identifier that does not rely on sight | Guiding visitors of many languages through a venue without words · Turning facility or sport categories into marks legible from a distance |
| Type | Dot diameter and spacing follow the standard, never adjusted for looks | Draw every mark on one grid and stroke weight, human proportions shared |
| Composition | Set below or beside the print, with room for a finger to travel | Fit all symbols to a square frame with matched margins and optical center |
| Material | Materials that hold dot height, no coating that rounds the domes | Single color silhouettes, minimum size and viewing distance decided first |
| Caution | Shrinking or tightening the dots to tidy the look drops them below the resolution of a fingertip, and nobody can read them. | Drawing each mark as a picture lets stroke and proportion drift, the set stops reading as a system, and meanings swap at a distance. |
