Disabilities: Challenges and Solutions Flashcards
Solve for:
Cannot see TEXT on digital or electronic interfaces (computers, automated teller machines (ATMs), mobile devices, airport kiosks, televisions, printers, copiers, phones, GPS devices, etc.)
- Screen readers
- Self-voicing interfaces and applications
- Refreshable braille output devices
Solve for:
Cannot use screen readers on digital content and interfaces not designed with accessibility in mind
- Interface designers and content authors can edit the markup to make it compatible with the assistive technologies used by blind people.
Solve for:
AT for people who cannot see when walking
• Canes help blind people feel their surroundings as they walk.
• Service animals (e.g. “Seeing Eye” dogs),
• GPS-based walking instructions with an audio interface
• Raised tiles on the ground
• Eliminate low-hanging architectural features
• Clear pathways without obstructions in hallways, sidewalks.
Solve for:
Cannot see signs or other text on buildings or other areas in the built environment
- Map and geolocation applications on mobile devices can announce the names and descriptions of buildings and other location-related information.
- Braille labels and descriptions on entrances, rooms, bathrooms, historical markers, and other points of interest can allow blind people to explore and understand their surroundings, as long as the person knows braille, and as long as the braille labels are easy to find.
- Tactile models of the exterior of buildings, or of floorplans of the interior of buildings help blind people form a mental map of their surroundings.
Solve for:
Cannot see or feel the controls on flat interfaces on consumer devices such as microwaves, ovens, dishwashers, etc.
- Alternative interfaces with knobs or other tactile controls
- Audio interfaces
- Remote control through applications on mobile devices
Solve for:
Cannot read the text on the containers or packaging for consumer items such as medicine, toothpaste, shampoo, sunscreen, hand cream, personal care products, foods, drinks, candy
- Embossed braille (or braille stickers) on packaging and product containers
Solve for:
Cannot read money to determine its value
- Applications on mobile devices can photograph the money and read the value to blind people.
- Paper bills and coins could be manufactured in different sizes, shapes, or textures to allow blind people to distinguish the value based on touch.
- Non-cash systems of payment can allow blind people to make financial transactions via computers, mobile devices, or on-site payment hardware with screen readers or self-voicing output.
Solve for:
Cannot read books, magazines, posters, postal mail, or other printed materials
- Optical character recognition software
- Information can be placed online or in other digital formats to allow blind people to read the materials using their own assistive technologies.
Solve for:
Small text can be hard to read.
- Screen magnifiers can enlarge the items on the screen to make them easier to read.
Utilities to enhance contrast, change colors, or alter other aspects of visual appearance can improve legibility. - Screen readers can supplement screen magnifiers by reading interfaces and content out loud to users through synthesized speech, but only if the digital information has been designed to be accessible.
- Self-voicing interfaces (on ATMs, kiosks, transportation systems, etc.) and applications can communicate to users without the need for a screen reader, but these are appropriate mostly for broadcasting information, because they usually do not interact with the interface or content as screen readers do.
- Alternative large print versions of small print text can make printed materials easier to read.
- Alternative digital versions (web, mobile applications, etc.) of printed materials can give users the ability to read the materials using their own assistive technologies.
Solve for:
Low contrast text can be hard to read.
- Software or hardware options can enhance the contrast of digital text.
- Interface designers and content creators can choose color combinations with high enough contrast to easily read
Solve for:
For people with color blindness, certain color combinations—red and green in particular—can be difficult to distinguish
- Materials can be designed in a way that does not depend on color as a way to convey information.
Solve for:
For people with deafblindess, digital text cannot be seen
A screen reader can convert text to braille on a refreshable braille device, or “printed” in a braille embosser.
Solve for:
For people with deafblindess, audio (including the audio portion of videos) cannot be heard
A text transcript of the audio can be converted to refreshable braille by a screen reader, or “printed” in a braille embosser.
Solve for:
The audio portion of videos cannot be heard
- Provide synchronized captions with videos
- Provide sign language interpretation
Solve for:
Audio content cannot be heard
- Provide a transcript
- Provide sign language interpretation
Solve for:
Speeches and talks cannot be heard by deaf people in the room
- Provide sign language interpretation
- Provide live captions on a monitor during the speech
Solve for:
Doorbells, alarms, and other sounds may not be heard
- Provide alternative visual alerts, such as lights that flash, pulse, dim, turn on, or turn off.
Solve for:
May be unable to use a mouse due to difficulty or inability to use hands
- Alternative keyboards, mouth sticks, single switch devices, speech recognition software and eye tracking technologies enable users to use a computer without the need for a mouse
- Developers and designers can ensure digital content is accessible using keyboard devices
Solve for:
May need more time to interact with digital content and interfaces due to slower movements
- Interface designers and developers can alert users to session timeouts and provide users with a way to adjust the time, extend the time or turn off the time limit
Solve for:
Wheelchair users are unable to use steps
- For building entrances, accessible ramps in addition to steps should be provided, and accessible parking should be provided
- For steps within buildings, ensure that ramps and elevators are provided and accessible
- Ensure that accessible routes outside and within the building are labeled and clearly identifiable
