Adaptive Solutions, Assistive Technology

Assistive and adaptive technologies are two types of tools or solutions that do share some common ground. However, adaptive and assistive devices are not interchangeable terms: they indicate different roles. You can find more details on different adaptive and assistive technologies in this article.

Assistive Technologies: Helpful Tools and Systems for All Abilities

These versatile, readily available assistive tools and devices can help people with various needs, and are not necessarily intended to be disability-specific. Examples of everyday products include magnifiers, used to read small text, crowded labels, or view pictures in greater details, as well as:

• Voice commands can be used by a busy professional or by someone with limited mobility to record notes, control smart home devices, operate a computer, or dictate text and messages.
  
• Closed captioning can be useful for people learning a new language or keeping up with a fast-paced lecture. And, they’re useful for people with hearing loss who want to access spoken dialogue and sound effects in a TV show or movie.
  
• Text-to-speech (TTS) converts written text to audible speech, which is an accessibility feature for people with visual and learning disabilities. However, anyone can use TTS to listen to articles or books while doing other tasks, or have digital assistants read messages aloud while driving.

Adaptive Technologies: Devices & Applications for People with Disabilities

Adaptive technologies are a branch within assistive technology. Adaptive tech includes tools specifically designed for people with disabilities, such as prosthetic limbs that work with brain-computer interfaces or mobility-enhancing exoskeletons. These technologies target specific disabilities, providing focused support.

The Impact of Adaptive Technology

Some of the far-reaching benefits of adaptive tools and systems include:

Exploring Adaptive Tools, Common and Uncommon

While there are many adaptive technology solutions, from software to simple tools, some adaptive tools and systems that are only likely to be of interest to persons with a disability include:

• Wheelchairs
  Yes, even simple manual wheelchairs are considered adaptive tools. Advanced electronic wheelchairs offer customizable control systems, which can be operated through minimal movement, accommodating various levels of mobility impairments.
  
• Eye-Tracking Systems
  By monitoring user eye movement, these devices offer uses with mobility impairments a way to control and interact with computer interfaces and applications.
  
• Screen Readers
  These are available as both external tools and software applications, for use on computers and mobile phones or devices. They convert digital text into speech. Their main purpose is to announce content and functionality to people who are blind or visually impaired.
  
  While screen readers could also be used by someone without a disability of any kind, that is not their intended function, and it rarely happens.
  
• Adaptive Keyboards
  These are built with customizable layouts and features, offering alternative and adjusted input methods.
  
• Large Print Keyboards
  Although they are not always customizable, these are a subset of the adaptive keyboard category. With oversized letters and keys and high-contrast colors, these keyboards make typing easier for users with visual and mobility impairments, as well as those with fine motor skill difficulties.
  
• AI-Powered Smart Devices
  Intelligent devices that adapt and respond to voice commands and user preferences are already a popular tool, and although some may fall into the category of assistive device, others are specifically designed to aid people with mobility or dexterity challenges to control their surroundings. For example, with these devices, users can use their voice to power on or off as well as adjust settings for lights, thermostats, and appliances.
  
• Augmentative and Alternative Communication (AAC) Devices
  These are communication tools used by individuals with speech loss or speech disabilities such as aphasia. An example of an AAC device could be a speech-generating system with picture symbols that helps convey ideas for someone cannot speak out loud. Or, AAC could mean something as low-tech and powerful as symbol cards, held up by a person with a speech impediment to express themselves.
  
• Smart Prosthetic Limbs
  While prosthetic limbs have been around for centuries, these modern versions offer intuitive control and natural movement capabilities, through the use of advanced sensors and technology.
  
• Exoskeletons
  Wearable robotic structures, these are mostly used to help a person stand and walk in spite of a severe mobility impairment or partial paralysis.
  
• Brain-Computer Interfaces (BCIs)
  These systems connect directly to the brain, where electrodes capture brain activity. Algorithms decode the neural patterns. For robotic or smart prosthetic limb activation, processed signals are then transformed into control commands, which can activate the limb according to the motion intent transmitted from the brain. Brain-spine interfaces (BSIs) have been successfully used to help a person with tetraplegia, or full body limb paralysis, due to a spinal cord injury, walk naturally once again.
  
  Other uses of BCIs include speech synthesis, where brain signals are translated into vocal patterns, and environmental control software which can, for example, help someone turn lights on and off.
  
  Brain-computer interfaces (BCIs), also called brain-machine interfaces or BMIs, are still a developing technology, and are currently available in various stages of development and functionality, depending on the specific application and level of invasiveness. Highly functional BCIs exist within research settings and controlled clinical trials for movement control and basic communication such as word selection. These often require surgical implantation of electrodes and other stimulation systems, but demonstrate promising results. Non-invasive BCIs using EEG technology are also used in research and some clinical settings for communication and biofeedback applications. However, their accuracy and speed limitations may make them less suitable for some more complex actions.
  
  Limited BCIs for commercial use are available primarily as non-invasive EEG systems for gaming, meditation, and biofeedback training. Their capabilities are currently restricted compared to research-grade systems. Surgically implanted BCIs for personal and commercial use are not yet available in any stable, reliable format. Widespread accessibility and daily use of BCIs for complex tasks are also still in the future.
  
  Brain-computer interfaces have immense potential to improve quality of life for people with motor and dexterity impairments, but they also have dangers that must be taken into consideration, including the risks inherent to brain surgery, and the possibility of a BCI malfunction affecting or injuring the brain. Ethical impact and user privacy as well as regulatory approval are also key concerns of BCI research.
