TouchSight

Make a diagram readable by touch in under a minute

Teachers of blind students redraw science diagrams by hand: removing clutter, swapping print for braille, keeping lines far enough apart to feel. TouchSight does the first draft for them.

Or pick any sample on the left, or upload your own.

How it works

Reads the labels printed on the diagram (OCR).
Follows each leader line to the part it names.
Segments that part with Segment Anything.
Redraws it for touch: bold outlines, textures instead of colours, braille labels, 3 mm spacing (BANA guidelines).
Checks the result and lets you fix any label before printing.

Everything runs on your computer. The first run downloads about 90 MB of models, which your browser then caches.

2 Review labels

Fix a word, merge a split label (⤒) or remove one (✕). The page updates instantly.

What the lines and patterns mean

Colour can't be felt, so named parts are marked with bold edges (and, if switched on, a distinct texture each).

3 Guideline check

Check	TouchSight	Edge tracing

Automated checks derived from the BANA Guidelines and Standards for Tactile Graphics (2022). They do not replace review by a qualified transcriber.

4 Export

Print on plain paper, photocopy onto swell paper, then run it through a fuser (e.g. PIAF). The printed version is pure black: the grey label pills appear on screen only.
