Brief History of Assistive Technologies
Assistive technologies have come a long way since their inception in the early 20th century. Initially, these technologies were designed to help people with disabilities to perform tasks that they would otherwise be unable to do. Over time, the range of assistive technologies has expanded, and they are now used by people of all ages and abilities to enhance their lives in various ways.
One of the earliest examples of assistive technology was the wheelchair, which was invented in the late 1500s by the Italian architect, Giovanni de’ Francesco. However, it was not until the late 1800s that the modern wheelchair was developed, with the introduction of lightweight materials and more maneuverable designs.
In the early 20th century, other assistive technologies began to emerge, such as hearing aids and glasses. These devices were initially quite basic, but they quickly evolved into the sophisticated tools that we know today. For example, hearing aids have gone from being large, cumbersome devices that only amplified sound to small, discreet devices that can connect to smartphones and stream audio directly into the user’s ear.
In the latter half of the 20th century, assistive technologies really took off with the advent of computer technology. The first screen reader programs were developed in the 1980s, allowing people with visual impairments to use computers for the first time. Since then, there has been a proliferation of assistive technologies designed to help people with a wide range of disabilities, including voice recognition software, text-to-speech software, and specialized input devices.
Today, assistive technologies are more accessible than ever before, with many devices available at affordable prices or even for free. There are also many organizations and resources available to help people find the right assistive technology for their needs, such as the Assistive Technology Industry Association and the National Center for Assistive Technology.

Each type has its own unique features and benefits, and the choice of which one to use will depend on the individual’s specific needs and preferences.
Cochlear Implants
Cochlear implants are surgically implanted electronic devices that provide a sense of sound to people with severe hearing loss or deafness. Unlike hearing aids, which amplify sound, cochlear implants work by directly stimulating the auditory nerve with electrical signals. This allows the brain to interpret sound, even if the ear is not able to hear it on its own. Cochlear implants are typically recommended for people who have little or no benefit from hearing aids, and they require regular maintenance and follow-up appointments with a healthcare provider.
FM Systems
FM systems are assistive listening devices that use a microphone and a transmitter to amplify sound and reduce background noise. They are commonly used in classrooms, meetings, and other public settings to improve the ability to hear and understand speech. FM systems typically consist of a microphone that is worn by the speaker, a transmitter that sends the signal to a receiver, and a receiver that is worn by the listener. This technology can be especially helpful for people with hearing loss, as it allows them to hear the speaker more clearly and reduces the impact of background noise.
Cognitive and Memory Assistive Technologies

Reminder Systems
Reminder systems are assistive technologies that help individuals remember important events, appointments, and tasks. These systems can be electronic or manual and can be programmed to send reminders through various means, such as phone calls, text messages, or emails. Some reminder systems are also designed to be integrated with other assistive technologies, such as smart home devices or wearable technology.
Organizational Tools
Organizational tools are assistive technologies that help individuals with cognitive and memory impairments to organize and manage their lives. These tools include electronic calendars, which can be synced with smartphones or other devices, and can be used to schedule appointments, events, and tasks. Other organizational tools include checklists, which can be used to keep track of important tasks and reminders, and can be customized to meet individual needs.
