Appendix A: Accessibility Guidelines for Developing ATMs
This section provides comprehensive accessibility guidelines to ensure ATMs are inclusive for individuals with diverse needs.
A.1 General Design Principles
Key considerations to ensure user-friendly designs.
- A.1.1 Unobstructed Access: Ensure clear, obstacle-free paths with adequate space for wheelchair users.
- A.1.2 Height and Reach: Position input controls and screens at heights accessible to both standing and seated users.
- A.1.3 Standardised Design: Maintain consistent placement and design of components across all devices.
- A.1.4 Feedback Mechanisms: Provide tactile, auditory, and visual feedback for all user actions.
A.2 Input and Output Accessibility
Guidelines for designing accessible input and output interfaces.
A.2.1 Keypads
- A.2.1.1 Use raised, tactilely discernible keys.
- A.2.1.2 Ensure consistent arrangement of number pads across all devices.
- A.2.1.3 Contrast keypads against surrounding surfaces for visibility.
A.2.2 Touchscreens
- A.2.2.1 Provide physical or tactile alternatives to touch interfaces.
- A.2.2.2 Ensure touchscreens meet WCAG AA contrast requirements.
- A.2.2.3 Integrate screen-reading and voice guidance functionality.
A.2.3 Audio Feedback
- A.2.3.1 Equip devices with standardised audio jacks and Braille instructions.
- A.2.3.2 Attach headphones by default and position them consistently.
- A.2.3.3 Provide clear, speech-enabled audio instructions and feedback.
A.3 Physical Interface Accessibility
Recommendations for improving physical component usability.
A.3.1 Card Slots
- A.3.1.1 Standardise slot position and orientation with Braille instructions.
- A.3.1.2 Use a swipe mechanism instead of retaining cards throughout the process.
A.3.2 Cash and Check Slots
- A.3.2.1 Clearly differentiate cash and check slots with tactile markers or Braille labels.
A.3.3 Security Authentication
- A.3.3.1 Standardise whether ATM rooms require authentication.
- A.3.3.2 Provide tactile or Braille instructions on doors or handles.
A.4 Assistive Features
Features to aid users with specific accessibility needs.
A.4.1 Voice Guidance
- A.4.1.1 Provide real-time voice instructions for navigation and operations.
- A.4.1.2 Deliver clear, timely feedback to reduce user confusion.
A.4.2 Braille Labels
- A.4.2.1 Include Braille instructions on buttons, slots, and jacks.
- A.4.2.2 Provide Braille-labeled ATM cards indicating magnetic strip orientation.
A.4.3 Haptic Feedback
- A.4.3.1 Integrate haptic feedback for tasks like button presses and slot usage.
A.5 Environmental Accessibility
Address external factors that impact user experience.
A.5.1 Lighting
- A.5.1.1 Ensure proper lighting to assist users with partial vision.
- A.5.1.2 Avoid glare or reflections on screens.
A.5.2 Noise Reduction
- A.5.2.1 Minimise ambient noise to improve the effectiveness of audio instructions.
A.5.3 Signage
- A.5.3.1 Provide high-contrast, large-print signage with tactile elements for guidance.
A.6 Additional Considerations
Strategies for user-centric design and iterative testing.
- A.6.1 Build trust with users through clear, intuitive interfaces.
- A.6.2 Conduct usability testing with diverse user groups.
- A.6.3 Explore accessibility features for hearing and motor impairments.
