How to Create a “PROPER BRAILLE SIGNS”

 Dear all

Let’s delve into the crucial aspects of maintaining accurate tactile signs, including thickness, character size, style, color contrast, and the geometry of Braille elements:

1. Thickness:

Why It Matters: The thickness of tactile signs impacts their durability and readability. Signs that are too thin may warp or break easily, ( if Acrylic is used), while overly thick signs can appear bulky and obstructive and may slide down or fall due to weight if not fixed or mounted properly. 

Well proven thickness would be 3mm for Acrylic base.

Hence it is better to use High impact modified acrylic, specially formulated laminates, excellently engineered products like Rowmark, Gemini, IPI or P-mark of GGK. If this HIMA sheets are used, even 1.6 mm  is enough. These materials are opaque and surface finish is non glare and has advantage of self dual color engraving.

Ideal Thickness: Tactile signs should have a thickness of approximately 1/32 inch (0.8 mm). This ensures they are sturdy enough to withstand wear and tear without being overly prominent.

2. Character Size:

Importance: Proper character size ensures readability for both sighted and visually impaired individuals.

Braille Characters: Braille dots should have a diameter of 0.059 inches (1.5 mm). Convex in nature. This standard size allows users to distinguish individual dots by touch.

Raised Characters: Raised characters (such as letters and numbers) should be at least 5/8 inch (16 mm) in height. Larger characters enhance visibility and readability.

3. Style and Font:

Sans Serif Fonts: Use sans serif fonts (e.g., Arial, Helvetica) for raised characters. These fonts lack decorative flourishes, making them easier to recognize.

Clear and Simple: Opt for clear, simple letterforms. Avoid overly ornate or intricate styles that may confuse users.

4. Color Contrast:

High Contrast: Ensure a strong contrast between the background and raised characters. High contrast improves readability.

Color Combinations: Dark characters on a light background or vice versa work well. For example:

Black characters on a white background.

White characters on a dark blue background.

Avoid Low Contrast: Low contrast strains the eyes and hinders readability.

5. Geometry of Braille Elements:

Braille Cells: Each Braille character consists of a 2x3 grid of dots (referred to as a Braille cell).

Dot Placement:

The dots are arranged in two columns, with three dots in each column.

Left first column dots are 1,2and3.

Right column is 4,5 and 6

Otherwise arranged in three rows

The top row contains dots 1, 4

The middle row is 2 and 5,

The bottom row is 3 and 6.

Spacing: The distance between adjacent Braille cells should be at least 3/8 inch (9.5 mm) to prevent accidental overlap.

Very Important:

It is very important to have Tactile Raised Letters in accordance with the guidelines in all “CAPITALS “ to be followed by Braille Script in Grade1 in India,Australia, and more whereas GRADE2 should. be for USA. Remember, accurate tactile signs are essential for creating an inclusive environment. By adhering to these guidelines, we ensure that everyone can access critical information independently.

Accessibility & its Importance

This tiny article is written, highlighting the importance to follow the accessibility acts like ADA,ADAG,OSHA strictly to achieve our primary aim for finding proper accessibility solution in making BRAILLE & TACTILE signs.

Ensuring accessibility is not just a legal obligation; it’s a fundamental step toward creating an inclusive and equitable environment for everyone. Let’s delve into the significance of adhering to accessibility acts like the Americans with Disabilities Act (ADA), the Architectural Barriers Act (ADAG), and the Occupational Safety and Health Administration (OSHA) when designing Braille and tactile signs:

ADA and ADAG Compliance:

Equal Access: The ADA and ADAG mandate that public facilities provide equal access to individuals with disabilities. Braille and tactile signs play a crucial role in achieving this goal.

Navigational Aid: Braille and tactile signs guide people with visual impairments by providing essential information about room numbers, restrooms, elevators, and other spaces. These signs empower individuals to independently navigate public buildings.

Legal Requirement: Failure to comply with ADA and ADAG standards can result in legal consequences, including fines and penalties. By following these regulations, organizations demonstrate their commitment to accessibility and avoid potential legal issues.

Tactile Sign Importance:

Accessibility: Tactile signs are specifically designed for touch. Raised characters and Braille allow individuals who are blind or have low vision to identify rooms, floors, and other spaces.

Doorway Cues: Doorways serve as natural cues for locating signs. Tactile signs placed near doorways ensure that people can find essential information by touch.

Exit Safety: OSHA requires Braille and tactile exit signs. In emergency situations, these signs guide individuals safely toward exits. Properly marked doors prevent confusion and enhance evacuation procedures1.

Visual Significance:

Low Vision Accessibility: Visual requirements for signs ensure they are accessible to people with low vision. High contrast, legible fonts, and appropriate character sizes are essential.

Content Diversity: Signs often display multiple types of content (e.g., room numbers, hours of operation, occupant names).

Each content type must be evaluated for visual and tactile accessibility2.

Non-Glare Finish: Following ADA rules includes using non-glare finishes to enhance readability for all users. 

In summary, strict adherence to ADA, ADAG, and OSHA guidelines ensures that Braille and tactile signs fulfill their purpose: providing essential information, promoting independence, and contributing to a more accessible world. Let’s continue championing accessibility for all
