Summary
This poster paper introduces an initial haptic-based system for teaching Arabic letter handwriting to students with visual impairments. Handwriting requires coordination of vision and hand movement, making it particularly challenging for visually impaired students who cannot see their strokes or access visual feedback about letter formation. While a small number of handwriting training systems exist for visually impaired learners (notably McSig for English cursive and a Kanji system for Japanese), no complete Arabic handwriting training system existed prior to this work. Arabic script presents unique challenges for haptic-based training: it is written right-to-left (with numbers left-to-right), most letters are cursive and connected within words, there are no upper or lower cases, characters can extend above or below the line, and each letter can appear in up to four different forms depending on its position in a word. The system uses a Phantom Omni haptic device to provide force and audio feedback, with full and partial guidance modes through haptic playback, plus automatic evaluation of student progress.
Key findings
The paper presents the motivation and architecture for the system, noting that Arab schools for visually impaired students currently focus exclusively on teaching Braille rather than handwriting Arabic letter shapes. The authors argue that handwriting mastery provides multiple benefits beyond communication: it develops spatial skills, enables pen-based authentication for personal security, reduces discrimination, increases confidence, and helps increase literacy levels. The system offers two guidance modes — full guidance (where the haptic device leads the student through the complete letter path) and partial guidance (where some assistance is provided but the student must contribute more independently). Previous handwriting systems for visually impaired students relied on evaluation by a sighted person or character recognition; this system aims to provide automatic progress evaluation. The paper describes preliminary development of one system component, with the full system still under construction at the time of publication.
Relevance
This research addresses accessibility in a non-Western script context, highlighting how assistive technology solutions developed primarily for Latin-based writing systems do not transfer directly to other scripts. The unique characteristics of Arabic writing — right-to-left direction, cursive connections, positional letter variants — require purpose-built solutions rather than adaptations of existing English-focused tools. For accessibility practitioners, the paper illustrates the broader principle that accessibility solutions must account for linguistic and cultural diversity. The argument that handwriting remains valuable even in a digital age — for spatial skills, authentication, confidence, and literacy — applies across disability contexts. The work is preliminary, presenting the system architecture without formal user evaluation, but it addresses a genuine gap in assistive technology for Arabic-speaking visually impaired communities.
