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. 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. |
