Assistive technology (AT) offers many people with a disability, impairment, or limitation enhanced ability and greater independence.
You’re disabled under the Equality Act 2010 if you have a physical or mental impairment that has a ‘substantial’ and ‘long-term’ negative effect on your ability to do normal daily activities.
There has been a significant increase in recent years in the range and availability of assistive technology at all levels of complexity and covering a broader spectrum of potential users. Now much more commonplace it is used in the home, school, workplace, socially and recreationally, covering all aspects of daily living.
While some assistive technology can be purchased off-the-shelf and needs little or no input from experts, other AT can be much more complex requiring specialist expertise, and possibly bespoke design and/or set-up from a specialist service.
For optimum benefit it is important to match the right technology to the user’s needs; this often requires input from an AT specialist. Advice should be sought from the many services and organisations offering help, who you approach will depend upon disability and level of need.
Use the Professional Services section to get an understanding of the types of services available and any entitlement to an assessment, funding, or free provision of assistive technology.
If you are looking for a better understanding of assistive technology products and what devices are available then look in the AT Products and Suppliers section to identify the most relevant websites to search and products to purchase.
If you want to understand what professions work in the field of assistive technology, what they do, or who to seek for advice then look in section Therapists and Assistive Technology Professionals.
For an understanding of the different categories of assistive technology and terminology used to help with your search for information then look in section Definitions and Categories of AT.
The list below shows the main areas of disability where AT can be of benefit.

Scope of Assistive Technology Products and Devices
Assistive technology can range from simple (low tech) mobility aids and adapted utensils and products to help around the home, such as walking frames and jam jar lid openers, as shown opposite, to more sophisticated and complex (high tech) assistive technology such as that used by Professor Stephen Hawking.
Stephen Hawking is often referred to (as an AT user example) when describing and explaining assistive technology. Even though he is profoundly physically disabled as a result of contracting motor neurone disease, assistive technology enables him to continue his world leading research in cosmology and theoretical physics. Still active at Cambridge University and known around the world Stephen travels for appearances and lectures, communicating using his computerised voice system with the distinctive electronic voice (speech synthesizer) that has become part of his identity - modern speech synthesizers are now much more human sounding and true voice like.
Aside from his medical equipment and care needs that are constantly present, Stephen makes use of a range of assistive technologies configured for his specific needs, the main areas are listed below and can be seen from the photos opposite. More details can be found on his official website www.hawking.org.uk
- Powered wheelchair (attendant controlled)
- Adapted road vehicle to accommodate wheelchair
Seating and Positioning
- Contoured seating and pressure management cushions
- Adapted headrest providing position and posture support
Communication Aid and Computer Access
- Computer based voice output communication aid (VOCA)
- EZ Keys software for text/character entry (scan and select)
- Word prediction software
- Speech synthesizer
- Computer Access
- Windows based tablet computer combining VOCA and computer access with EZ Keys software for email, internet access, Notepad, Skype etc.
- Mounting system to attach computer to wheelchair
- Bespoke single switch system attached to spectacles, using infra-red sensor detecting cheek movements, to enable scan and select computer access
The key component that enables Stephen to access technology and communicate is the infra-red switch that he activates by a small muscle movement in his cheek. The computer automatically scans rows and columns (e.g. each cell or key of an on-screen keyboard) and when the cell (key/character/word) is reached he activates the switch to select the cell.
The process of scan and select using a single switch is a very slow process, even when using word prediction it can take about a minute for a single word. Much of Stephen's public speaking and lectures are written beforehand and delivered in sentence chunks by activating the speech synthesizer. Real-time conversations, that are more than brief comments, tend to take time for Stephen to respond.
