Background
Many accessibility features are currently in use in Second Life. These include tools built into the viewer software and the structure of the world itself, as well as accessibility tools available in all modern computer operating systems. Assistive technology, such as screen reader software and onscreen keyboards that many people with disability use, works in Second Life. As you might expect in a resident-developed environment, various accessibility solutions have been developed and shared by community members.
One goal of this wiki page is to highlight some of these accessibility features for those who would need them in order to be able to access and function in Second Life. Another goal is to remind content designers and other Second Life residents of ways to make the virtual world more accessible for all users. Disability can happen to any of us at any time, so it’s always wise to be prepared.
Accessibility is everyone’s responsibility. Please do your part.
Definitions
Accessibility means the degree to which an object, function, service, or environment is available for use by as many people as possible.
This is an internationally recognized symbol for accessibility.
In many countries, accessibility is legislated and thus may be more clearly defined.
Universal Design (UD) is an approach to creating structures, products, and environments that are accessible to all people.
Disability means a lack of one or more human abilities, which include physical, mental, emotional, sensory, and developmental abilities. The effects of chronic illnesses are often included as disabilities.
The term “disability” is often contrasted with the term “impairment,” which indicates a characteristic of an individual.
Assistive technology (AT) includes all devices (whether assistive, adaptive, or rehabilitative) that help people accomplish tasks they can not do adequately or at all without the device.
“People first language” is one way of emphasizing the similarities among all people before recognizing differences.

Accessibility Issues with Virtual Worlds
Some conditions may be more disabling in a virtual environment than in the physical environment. It is important for people with these disabilities that virtual environments need to be made accessible.
- Keyboard/Mouse Impairment Accessibility Issues
Typically, a computer accepts input from both keyboard and mouse. Normally the keyboard is used for text input and moving the avatar around. Similarly, the mouse is normally used for User Interface navigation.
Keyboard/mouse impairment makes the use of a regular keyboard and/or mouse difficult. It may be caused by upper limb paralysis or amputation, neurological diseases such as muscular dystrophy or cerebral palsy, degenerative conditions such as arthritis or carpal tunnel, or blindness.
- Reading Impairment Accessibility Issues
Much information, including local chat, IMs, user interface menus, posters and signs, is provided in virtual worlds through text. Reading impairment also applies to obtaining information from images.
Reading impairment includes blindness, visual impairment, and dyslexia (a form of learning disability that includes print impairment). People who cannot understand the language of the text are also reading impaired. Reading impairment may also come with aging.
- Hearing/Speech Impairment Accessibility Issues
Virtual worlds were originally entirely text-based. Once Voice was introduced, it became useful in many aspects of virtual worlds to be able to hear and speak.
Hearing impairment often accompanies aging. It also includes various levels of D/deafness, whether congenital or caused by accidental injury, or auditory impairment from neurological diseases such as multiple sclerosis, Parkinson’s disease, or cerebral palsy. Hearing impairment may also be related to different levels of comprehension of sounds. Reasons for being unable to speak clearly include Deafness, but also stuttering, traumatic brain injury, anxiety, stroke, and oral/throat cancer.
- Other Accessibility Issues
Other accessibility issues include learning disabilities, attention deficits, memory issues, limited cognitive capabilities, and chronic fatigue. Learning a new skill requires attention, effort, and practice. These capabilities may be difficult for someone with these types of other accessibility issues.
Self-identity is also sometimes an accessibility issue. For instance, some people who use a wheelchair in real life prefer their avatar to also be in a wheelchair. Others may prefer to appear as an amputee with a prosthesis, or to ambulate with crutches or leg braces. Some individuals use virtual worlds to hide or leave behind their visible disabilities. These representational choices should be respected, in addition to supporting the access needs of those whose disabilities affect their ability to function in a virtual world.
While aspects of Universal Design, such as ramps instead of stairs and providing multiple modes of communication, are important to include in virtual world creation, some physical world accommodations, such as designated handicapped parking spaces, are not necessary in virtual settings.
