Likewise, disability advocates point out that technology is often created without regard to people with disabilities, creating unnecessary barriers to hundreds of millions of people. Even the makers of AT technologies will often still argue that universal design

Personal Emergency Response Systems

Personal Emergency Response Systems (PERS), or Telecare
Telecare
Telecare is a term given to offering remote care of old and physically less able people, providing the care and reassurance needed to allow them to remain living in their own homes. The use of sensors may be part of a package which can provide support for people with illnesses such as dementia, or...

 (UK term), are a particular sort of assistive technology that use electronic sensors connected to an alarm system to help caregivers manage risk and help vulnerable people stay independent at home longer. An example would be the systems being put in place for senior people such as fall detectors, thermometers (for hypothermia

). Notably, these alerts can be customized to the particular person's risks. When the alert is triggered, a message is sent to a caregiver or contact center who can respond appropriately.

Technology similar to PERS can also be used to act within a person's home rather than just to respond to a detected crisis. Using one of the examples above, gas sensors for people with dementia can be used to trigger a device that turns off the gas and tells someone what has happened.

Designing for people with dementia is a good example of how the design of the interface of a piece of AT is critical to its usefulness. People with dementia or any other identified user group must be involved in the design process to make sure that the design is accessible and usable. In the example above, a voice message could be used to remind the person with dementia to turn off the gas himself, but whose voice should be used, and what should the message say? Questions like these must be answered through user consultation, involvement and evaluation.

Accessible Input devices for Computers

Sitting at a desk with a QWERTY keyboard and a mouse remains the dominant way of interacting with a personal computer. Some Assistive Technology reduces the strain of this way of work through ergonomic accessories
Ergonomics
Ergonomics is the study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities.The International Ergonomics Association defines ergonomics as follows:...

 with height-adjustable furniture, footrests, wrist rests, and arm supports to ensure correct posture. Key guards fit over the keyboard to help prevent unintentional key presses.

Alternatively, Assistive Technology may attempt to improve the ergonomics of the devices themselves:
  • Ergonomic keyboards reduce the discomfort and strain of typing.
  • Chorded keyboard

     and other alternative layouts may offer more ergonomic layouts of the keys. There are also variants of Dvorak in which the most common keys are located at either the left or right side of the keyboard.


Input devices may be modified to make them easier to see and understand:

  • Keyboards with big keys.
  • Keyboards with less and big keys, or multifunctional keys, such us the special keyboard PiTech, with only five big rounded keys, which is used with a special software for writing
  • Large print keyboard with high contrast colors (such as white on black, black on white, and black on ivory).
  • Large print adhesive keyboard stickers in high contrast colors (such as white on black, black on white, and black on yellow).

Augmentative and Alternative Communication (AAC)

Augmentative and alternative communication (AAC) is an umbrella term that encompasses methods of communication for those with impairments or restrictions on the production or comprehension of spoken or written language. AAC systems are extremely diverse and depend on the capabilities of the user. They may be as basic as pictures on a board that the are used to request food, drink, or other care; or they can be advanced speech generating devices, based on speech synthesis, that are capable of storing hundreds of phrases and words.

Modern use of AAC began in the 1950s with systems for users who had lost the use of speech following surgical procedures. During the 1960s the use of manual sign language grew greatly, but it was not until the 1980s that AAC began to emerge as an area in its own right. AAC is now used for a wide variety of speech impairments. Studies show that AAC use does not impede the development of speech, and may even result in a modest increase in speech production.

A great diversity of diagnoses, including cerebral palsy, intellectual impairment, autism, and many others, cover varying degrees of communication impairment. AAC interventions are highly individualized, taking into account specific abilities of language comprehension, social-relational characteristics, learning strengths and weaknesses, and developmental patterns for specific types of intellectual disabilities. AAC can be used to aid both spoken and written language, and can supplement or replace speech and writing as necessary. AAC can be a permanent addition to a person's communication or a temporary aid. The systems used in AAC include gestures, hand signals, photographs, pictures, line drawings, words and letters, which can be used alone or in combination to communicate.

Aided AAC makes great use of symbols, particularly for non-literate users, as well as a large variety of input methods. The specific access method will depend on the skills and abilities of the user. Body parts, pointers, adapted mice, joysticks, or eye tracking could be used, whereas switch access scanning

 is often used for indirect selection. In many cases, rate enhancements methods may be used to speed up the generation of messages. Clearly, an evaluation of a user's abilities and requirements is necessary to match a user with the most appropriate AAC method, input approach, and vocabulary. This evaluation requires the input of family, particularly for early intervention. Respecting ethnicity and family beliefs are key to a family-centered

Claims
Since children with autism process visual information easier than auditory information, when utilizing assistive technology claims that any time we use these devices with these children, we're giving them information through their strongest processing area (visual). Therefore various types of technology from "low" tech to "high" tech, should be incorporated into every aspect of daily living in order to improve the functional capabilities of children with autism.

Benefits
Regarding comprehension skills, increasing comprehension of tasks/activities/situations is essential in addressing skill areas such as organization, attending, self help, following directions, following rules and modifying behavior. As a result, the child becomes more independent. The following "low" tech visual support strategies can be created and used to benefit and assist the child in increasing his comprehension skills and thus decreasing the occurrence of challenging behaviors.

Consistent daily use of an individualized visual schedule will increase a child's organization skills and independent functioning throughout all aspects of his life and will ease transition through adulthood. There are numerous ways to present visual schedules for example an object schedule, 3-ring binder schedule, clipboard schedule, manila file folder schedules, and dry erase board schedules are all beneficial to increase a child's organization skills and independent functioning.

The use of a weekly/monthly calendar at both home and school can provide the child with important information regarding up-coming events/activities, rather than relying on auditory information. When the child asks when a particular event will occur, he can easily be referred to the visual calendar. Use of a visual calendar can also be helpful in assisting the child to understand when regularly scheduled events may not occur.

Outcomes
In a pilot study, Researchers Lacava, Golan, Baron-Cohen, and Myles explored the use of assistive technology to teach emotion recognition to eight children with Autism and the results indicated that after intervention, participants improved on face and voice emotional recognition for basic and complex emotions that were in the software. As well as for complex voice emotional recognition for emotions not included in Mind Reading.
