Assistive Technology

Assistive technology is a collective term for devices that help improve physical or mental functions in people who have these functions reduced for various reasons. The concept of assistive technology can include not only these aids in themselves, but also the services associated with their provision.

Division of assistive technologies
The technical advancement of assistive technologies does not necessarily reach "space research", the term assistive technologies includes, in addition to highly sophisticated aids that replace the function of sight, as well as a seemingly simple velcro that facilitates dressing.

In addition to aids of a more or less prosthetic nature, aids facilitating communication with a computer represent an extensive field of assistive technologies. Due to the great importance of computer technology and especially the Internet in contemporary communication, ensuring sufficient communication with the computer is a factor that fundamentally affects the quality of life.

Assistive technologies therefore cover a very wide area, the following areas can be included under the term assistive technology:


 * 1) Architectural modifications (e.g. housing adaptation)
 * 2) Sensory aids – aids facilitating perception (e.g. hearing aids, cochlear implant, glasses, artificial retina,...)
 * 3) Computer technology - specific software and hardware (e.g. reading programs, keyboards withBraille,...)
 * 4) Prostheses a orthoses
 * 5) Aids to facilitate personal mobility (e.g. wheelchair)
 * 6) Modification of furniture and equipment of the apartment
 * 7) Aids for recreation and sports
 * 8) Services including selection of appropriate aids and training in their use

Visual impairment and vision loss

Making it easier to work with the computer

 * the settings of most operating systems allow you to enlarge the text on the monitor
 * software that magnifies a part of the monitor
 * software readers – programs that convert text into spoken word
 * high contrast and large dimensions of the keyboard description
 * keyboard adapted for tactile orientation
 * replacing the mouse function with simple keyboard shortcuts
 * voice text input
 * "monitors" displaying text in Braille
 * recommendations for the creation of websites facilitating text processing by the reader

Making documents easier to read

 * magnifying glass
 * electronic magnifiers - unlike a magnifying glass, they display a larger area of ​​the document on the monitor
 * database of electronic documents in text form
 * database of electronic documents in audio form

Hearing impairment and hearing loss

Hearing Support

 * hearing aid
 * cochlear implant
 * stem implant

Substitution of hearing by other senses

 * warning devices - in the event that sufficient hearing cannot be achieved, an acoustic signal (alarm clock, doorbell, child's cry...) can be converted to another (light signals, small vibrations,...)
 * simultaneous interpretation into sign language
 * video phone connection

Movement disorders

Communication with the computer

 * trackball, joystick
 * dimensionally or ergonomically modified keyboards
 * a switch controlled by the blink of an eyelid, breath or movement of a limb
 * keyboard based on tracking eye movements (Eyegaze)
 * communication using the sensing of leg movements
 * communication using the sensing of mouth or tongue movements
 * voice input

Everyday life

 * wheelchairs
 * prosthetic devices
 * electronic control of environmental elements, their normal use is made impossible or difficult due to a malfunction (e.g. opening doors)
 * aids and structural modifications enabling the driving of a car
 * aids enabling or facilitating rehabilitation and exercise

Disorders of mental abilities

 * document readers (in case of a disorder associated with a reduced ability to read)
 * computer voice input (in case of a malfunction associated with a reduced ability to write)
 * dictionaries and spell check (especially dysgraphia)
 * audiovisual instructions for performing common activities (mental retardation, dementia)
