Qiming School: 631 High-Precision Braille Signs

Overview

Guangzhou Qiming School, located in Guangzhou, Guangdong Province, is a leading special education institution in South China, offering programs from primary to vocational levels for students with visual impairments. The school required an accessible wayfinding signage system that strictly followed national Braille standards and adopted a dual-recognition design to support both tactile reading for blind users and visual recognition for low-vision users. In this project, LC Sign delivered 631 sets of Braille door signage to establish a cohesive school signage system across key areas, ensuring accurate tactile readability, clear visual identification, and long-term durability under frequent use.

Challenges

• Multi-layered Standards and User Requirements: Serving visually impaired students requires significantly higher standards for tactile accuracy and consistency. All Braille content and structures had to strictly comply with national standards while addressing diverse user groups and age ranges.
• Integration of Tactile and Visual Systems: The project required simultaneous optimization of tactile readability (dot height, spacing, and layout) and visual clarity. Additionally, differentiated color strategies were needed to adapt to varying wall conditions (e.g., white vs. red walls), ensuring a cohesive and safe visual system.
• Large-scale Custom Production and Proofreading: Producing 631 customized signage units involved extensive Braille proofreading and strict quality consistency. Traditional methods were insufficient to balance tactile quality, durability, and production efficiency.
• Multi-scenario Implementation Coordination: The system had to adapt to various building types and wall materials while maintaining a unified numbering system. It also needed to ensure long-term durability under frequent touch and meet ergonomic installation requirements for different age groups.

Process

Phase 1: Site Research and System Planning

Conducted comprehensive site surveys and interviews with special education teachers to analyze student movement patterns and spatial recognition behavior. Established a hierarchical wayfinding logic system.

Phase 2: Design Development and User Validation

Developed both stainless steel and acrylic signage options. Through on-site tactile testing with students, the acrylic solution was selected. A color recognition system was created, including yellow borders for white walls to align with existing accessibility elements.

Phase 3: Process Optimization and Prototype Testing

Introduced 3D-printed hemispherical Braille dots, precisely controlled at 0.5mm height to balance tactile clarity and durability. Conducted real-world testing to refine tactile and visual parameters.

Phase 4: Detailed Design and Standardization

Finalized product structures and manufacturing standards. Developed unified dimensional specifications and installation guidelines. Established a dedicated proofreading process with school staff to ensure accuracy across all Braille content.

Phase 5: Mass Production and Quality Control 

Adopted a hybrid process combining laser engraving and 3D printing. Implemented a full-process quality control system to ensure consistency in tactile performance, dimensions, and visual quality across all units.

Phase 6: Delivery and On-site Installation

Executed categorized packaging and phased delivery. Installation was carried out by a professional team, with height adjustments based on different student age groups. Final checks ensured compliance with all tactile and installation standards.

Outcomes

• Unified & Accessible School Signage System: Successfully established a standardized Braille signage system across core campus areas, integrating tactile and visual recognition into a cohesive whole.
• Full Compliance and High Precision: All 631 signage units meet national standards, achieving zero errors in Braille content and consistent tactile quality.
• Enhanced User Experience: Ergonomic installation and optimized design significantly improved spatial recognition efficiency and independent mobility for visually impaired students.
• Proven End-to-End Capability: The project validated LC Sign’s capabilities as a school signage manufacturer, delivering a large-scale customized accessible signage system from research and design to production and installation while overcoming traditional manufacturing limitations.

Insights

This project demonstrates that a user-centered approach—combined with user experience validation and standardized process control—can effectively deliver high-quality accessible wayfinding systems.

In special education environments, early-stage research, cross-user needs analysis, and the integration of innovative manufacturing techniques with strict standards are critical to success. Close collaboration with end users ensures both content accuracy and practical usability, allowing accessibility design to truly serve its intended audience.
