Overview
ISO 19028:2016 - Accessible design: Information contents, figuration and display methods of tactile guide maps specifies how to design and present tactile guide maps that convey location and route information for people with visual impairment and blindness. The standard covers tactile maps for buildings, public transport, parks and immediate surroundings, addressing content, tactile figuration, display methods and installation considerations to support safe, smooth mobility.
Key topics and technical requirements
- Core components: Title, commentary, legend, tactile figures, tactile marks, braille/raised characters, scale and north direction when appropriate.
- Principles for content: Provide required and minimum information focused on the map’s purpose (orientation vs. route guidance); prioritize safety and smooth movement; ensure tactile readability and consistency with visual maps when both exist.
- Tactile figuration: Use convex lines/surfaces, concave surfaces, tactile marks and raised lettering. All tactile marks must be identifiable and explained in the legend.
- Dimensions & installation:
- Grip distance for desk installations: within 600 mm.
- Wall-mounted tactile area height: 1100–1600 mm from the floor (preferred centre at 1400 mm).
- Clearance under desk installations: 900 mm to allow wheelchair access.
- Booklet maps: avoid folds that hinder tactile reading.
- Map orientation & layering:
- Installed maps must correspond to real-world directions and present location.
- Do not overlay multiple storeys in one tactile map; provide separate maps per storey or use side-section views for transfer routes.
- Display methods & alternatives: Map type (installed, booklet, model) determines presentation. Electronic tags for audio guidance may supplement or replace some lettering/points.
- Documentation & provenance: Include production date and contact information.
Practical applications and users
ISO 19028:2016 is intended for:
- Architects, wayfinding and accessibility designers
- Urban planners, transport authorities and park managers
- Facility managers (public buildings, stations, museums)
- Manufacturers of tactile map panels and tactile signage
- NGOs and consultants advising on accessibility and orientation and mobility (O&M)
Use cases include wall-mounted tactile floor plans at building entrances, tactile maps in transit hubs, park orientation boards and portable tactile booklets for guided routes.
