Assistive technology is an umbrella term that includes assistive, adaptive, and rehabilitative devices for people with disabilities while also including touch education of children with sensory impairments process used in selecting, locating, and using them. Wheelchairs are devices that can be manually propelled or electrically propelled, and that include a seating system and are designed to be a substitute for the normal mobility that most people enjoy.
Wheelchairs and other mobility devices allow people to perform mobility-related activities of daily living which include feeding, toileting, dressing, grooming, and bathing. A walker or walking frame or Rollator is a tool for disabled people who need additional support to maintain balance or stability while walking. It consists of a frame that is about waist high, approximately twelve inches deep and slightly wider than the user. Walkers are also available in other sizes, such as for children, or for heavy people. A prosthesis, prosthetic, or prosthetic limb is a device that replaces a missing body part. Prostheses are specifically not orthoses, although given certain circumstances a prosthesis might end up performing some or all of the same functionary benefits as an orthosis.
Prostheses are technically the complete finished item. For instance, a C-Leg knee alone is not a prosthesis, but only a prosthetic component. The terms “prosthetic” and “orthotic” are adjectives used to describe devices such as a prosthetic knee. The terms “prosthetics” and “orthotics” are used to describe the respective allied health fields. Many people with serious visual impairments live independently, using a wide range of tools and techniques.
Examples of assistive technology for visually impairment include screen readers, screen magnifiers, Braille embossers, desktop video magnifiers, and voice recorders. Screen readers are used to help the visually impaired to easily access electronic information. These software programs connect to a computer to read the text displayed out loud. There are a variety of platforms and applications available for a variety of costs. This software is provided free of charge on all Apple devices.
Braille is a system of raised dots representing letters, numbers, punctuation, and words. Braille is a system of raised dots formed into units called braille cells. A full braille cell is made up of six dots, with two parallel rows of three dots, but other combinations and quantities of dots represent other letters, numbers, punctuation marks, or words. People can then use their fingers to read the code of raised dots. A braille embosser is, simply put, a printer for braille. Instead of a standard printer adding ink onto a page, the braille embosser imprints the raised dots of braille onto a page.
Some braille embossers combine both braille and ink so the documents can be read with either sight or touch. A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Computer users who cannot use a computer monitor use it to read a braille output version of the displayed text. Desktop video magnifiers are electronic devices that use a camera and a display screen to perform digital magnification of printed materials. They enlarge printed pages for those with low vision.
A camera connects to a monitor that displays real-time images, and the user can control settings such as magnification, focus, contrast, underlining, highlighting, and other screen preferences. A screen magnifier is software that interfaces with a computer’s graphical output to present enlarged screen content. It allows users to enlarge the texts and graphics on their computer screens for easier viewing. Similar to desktop video magnifiers, this technology assists people with low vision. After the user loads the software into their computer’s memory, it serves as a kind of “computer magnifying glass.
Wherever the computer cursor moves, it enlarges the area around it. A large-print keyboard has large letters printed on the keys. The “bump dots” on the keys, installed in this case by the organization using the keyboards, help the user find the right keys in a tactile way. Wearable technology are smart electronic devices that can be worn on the body as an implant or an accessory.
New technologies are exploring how the visually impaired can receive visual information through wearable devices. The deaf or hard of hearing community has a difficult time to communicate and perceive information as compared to hearing individuals. Thus, these individuals often rely on visual and tactile mediums for receiving and communicating information. A hearing aid or deaf aid is an electroacoustic device which is designed to amplify sound for the wearer, usually with the aim of making speech more intelligible, and to correct impaired hearing as measured by audiometry. This type of assistive technology helps people with hearing loss participate more fully in their communities by allowing them to hear more clearly. They amplify any and all sound waves through use of a microphone, amplifier, and speaker. Assistive listening devices include FM, infrared, and loop assistive listening devices.
