DISABILTIES
MOVEMENT
The most common assistive technologies associated with movement are wheelchairs, mobility scooters and power chairs
The most common learning disability is dyslexia, affecting approximately 80 to 90 percent of all learning disabilities.
Movement disorders are a challenge we will all face when we reach that stage in our lives, common examples include Parkinson's and function movement disorders.
Parkinson’s disease and other related disorders cause the limbs to shake rhythmically (tremor) when the body is at rest, and also cause muscles to tighten and become rigid, affecting posture — all of which can make it difficult to walk and engage in daily activities.
Communicating
Speech impairments are disorders of speech sounds, fluency, or voice that interfere with communication, adversely affect performance and/or functioning in the educational environment and result in the need for exceptional student education.
One of the most experienced speech disorders is stuttering. Other speech disorders include apraxia and dysarthria. Apraxia is a motor speech disorder caused by damage to the parts of the brain related to speaking.
Speech easy is a device that helps those who may have problems with stutters. SpeechEasy devices are similar in appearance to a hearing aid. However, rather than amplifying sound, SpeechEasy devices alter sounds that go through the device so that you hear your voice at a slight time delay and at a different pitch. The purpose of the delay and pitch change is to recreate a natural phenomenon known as the “choral effect.” The choral effect occurs when your stutter is dramatically reduced or even eliminated when you speak or sing in unison with others. This choral effect has been well documented for decades and SpeechEasy utilizes it in a small, wearable device that can be used in everyday life.
VISION
Visual impairment is a term experts use to describe any kind of vision loss, whether it's someone who cannot see at all or someone who has partial vision loss. Some people are completely blind, but many others have what's called legal blindness.

Short-sightedness usually occurs when the eyes grow slightly too long. This means that light doesn't focus on the light-sensitive tissue (retina) at the back of the eye properly. Instead, the light rays focus just in front of the retina, resulting in distant objects appearing blurred.
Long-sightedness is when the eye does not focus light on the retina (the light-sensitive layer at the back of the eye) properly. This may be because: the eyeball is too short. the cornea (transparent layer at the front of the eye) is too flat.
HEARING
Sensorineural loss is the most common type of hearing loss. It can be a result of aging, exposure to loud noise, injury, disease, certain drugs or an inherited condition.

Hearing loss (also called hearing impairment) makes it hard to hear or understand sounds. This happens when there is a problem with one or more parts of the ear, the nerves coming from the ears, or the hearing part of the brain. Some people are born with hearing loss. You can't prevent these kinds of hearing loss. But they can be assisted with the use of technology.
Hearing aids work by amplifying sound through a three-part system: The microphone receives sound and converts it into a digital signal. The amplifier increases the strength of the digital signal. The speaker produces the amplified sound into the ear.
Learning
Up to 10 percent of the population are affected by specific learning disabilities, such as dyslexia, dyscalculia and autism.
Dyslexia is the most common learning disability, this is a disorder that involves difficulty in learning to read or interpret words, letters, and other symbols, but that do not affect general intelligence. A simple widely universal solution can be found for this such as using an iPad to enlarge words and make them easier to read.
