Augmentative and Alternative Communication Service (AAC) – Compass

iPad adapted with assistive technology so that a brain injured person can communicate


Everyday tasks

Assistive technologies can enable disabled people to carry out everyday tasks they would otherwise be unable to do, such as communicating, using a computer, getting around in a powered wheelchair, controlling the television, lights or other household equipment.

Augmentative and Alternative Communication (AAC) are a type of assistive technology that enable people who have difficulties communicating, to use other methods to communicate when speaking is difficult. This may be through tools such as a picture or letter chart or may be through technology such as a computer which has a synthesised voice.

Compass is our assistive and rehabilitation technology service. The Compass team includes specialists in electronic assistive technology and rehabilitation technology. They  work with patients, as well as working with people referred from the community, other hospitals, nursing homes and other settings.

Commissioned by NHS England to be the specialised AAC service for adults in west London, Compass assesses people with complex AAC needs, provides AAC equipment and provides ongoing maintenance and support. It also provides support and training to local community teams who work with AAC.
