Comparing Computer-Based Drawing Methods for Blind People with Real-Time Tactile Feedback
summary
A tactile drawing workstation uses a binary pin-matrix display (104×60 pin matrix, ~20 Hz refresh) and four input modes — menu, gesture, freehand stylus (IR/ultrasonic pen, ~1200 dpi, brush tip, line‑of‑sight required) and ToF silhouette capture with depth segmentation and vectorization — to create editable shapes (move, scale, edit Bézier points). A within‑subjects study with 12 blind users finds all modalities usable, menu most accurate and preferred, SUS >70, pen most exhausting, silhouette least favored, and drawing takes ~20 minutes per image — ≈10× slower than sighted.
