Accessible LEGO CAD and Building Tools
This session explored the current landscape of accessible LEGO design and building technology, with a focus on opportunities for blind and low-vision users.
Existing Accessible LEGO Projects
Bricks for the Blind provides accessible LEGO building experiences through adapted instructions and workflows. LEGO Audio Instructions enables builders to follow spoken building instructions rather than relying exclusively on visual guides.
These projects demonstrate that accessibility support exists primarily at the instruction and building stage, rather than during the design process.
Voice-Controlled CAD
Several mature solutions already provide voice operation for professional CAD software, including:
- Voice2CAD
- CAD Assistant for AutoCAD
- Rubius Voice Control
These systems allow users to trigger commands, enter dimensions, automate workflows and navigate CAD software using speech.
Outcome
An accessible LEGO design environment would combines:
- Voice command input for LEGO model creation
- Structured model navigation
- Spoken spatial descriptions describing a LEGO model in 3D space
- Part placement validation
- Export to standard LEGO formats (LDraw, Studio, etc.)
- Export text-based instructions
- Optional generation of audio build instructions
