WebAIM: Motor Disabilities - Types of Motor Disabilities - 0 views

  • Spinal cord injuries can result in a state of paralysis of the limbs. Paralysis of the legs is called paraplegia. Paralysis of the legs and arms is called quadriplegia.
  • Individuals with paraplegia generally have no difficulty accessing the Internet. Individuals with quadriplegia, however, may have significant difficulties,
  • someone who has lost both limbs may need to make use of other technologies, such as the ones used by individuals with quadriplegia (head wands, mouth sticks, voice recognition software, etc.).

  • Cerebral palsy is an injury to the brain
  • resulting in decreased muscle control (palsy). The condition usually occurs during fetal development, but can also occur at or shortly after birth. Common characteristics of cerebral palsy include muscle tightness or spasm, involuntary movement, and impaired speech. Severe cases can lead to paralysis.
  • Many people with cerebral palsy are able to use computers, but usually have a difficult time using a mouse. Their arm movements are often too jerky and unpredictable to use a mouse effectively. They can usually use a keyboard, or an adaptive keyboard, though more slowly than individuals without cerebral palsy. Oftentimes they will use keyboards with raised areas in between the keys, to allow them to place their hand on the raised area, then press their fingers down onto the key that they wish to type. Regular keyboards can be adapted to this same purpose by the use of keyboard overlays. This reduces the likelihood of errors while typing.
  • Muscular dystrophy (MD) is a genetic disorder in which the genes for muscle proteins are damaged. It is characterized by the progressive degeneration of the muscles.
  • The assistive technologies used by individuals with MD depend on the severity of the condition, but generally include the same technologies already mentioned
  • (head wands, mouth sticks, adaptive keyboard, voice recognition software, etc.).
  • In individuals with multiple sclerosis (MS), the myelin (a layer of fatty tissue which surrounds nerve fibers) erodes, rendering the nerve fibers incapable of sending signals from the central nervous system to the muscles of the body. The milder cases of MS can result in one or more of the following symptoms: tremors, weakness, numbness, unstable walking, spasticity, slurred speech, muscle stiffness, or impaired memory. Severe cases can result in partial or complete paralysis. Not all individuals with MS experience all of the symptoms and, interestingly, the same individual may experience different sets of symptoms at different times. The types of technologies used are the same as for other motor disabilities.
  • Spina bifida is a congenital condition in which the spine fails to close properly during the first month of pregnancy.

    Key Concepts: Motor Impairments
    Challenges Solutions
    Users may not be able to use the mouse. Make sure that all functions are available from the keyboard (try tabbing from link to link).
    Users may not be able to control the mouse or the keyboard well. Make sure that your pages are error-tolerant (e.g. ask "are you sure you want to delete this file?"), do not create small links or moving links.
    Users may be using voice-activated software. Voice-activated software can replicate mouse movement, but not as efficiently as it can replicate keyboard functionality, so make sure that all functions are available from the keyboard.
    Users may become fatigued when using "puff-and-sip" or similar adaptive technologies. Provide a method for skipping over long lists of links or other lengthy content.

How do People with Disability Use and Experience Virtual Worlds and ICT: A Literature R... - 6 views

    There is wide agreement that information and communication technology (ICT) is a valuable tool for people with disability. Several research disciplines have focused on how people with disability can take advantage of the technology available for social, educational and personal purposes.
    @Rick thank you for sharing this! Do you work in this field?
    Hi Maggie, I do not. However, I'm seeking teaching opportunities in online education and I'd like to be prepared to deliver content to all types of learners as effectively and efficiently as possible.

The Faculty Room - 1 views

  • The Faculty Room is a space for faculty and administrators at postsecondary institutions to learn about how to create classroom environments and academic activities that maximize the learning of all students, including those with disabilities. Much of the content is duplicated in other publications, training materials, and web pages published by DO-IT. This site includes six primary areas that address issues faced by postsecondary educators (listed below).
