Assistive Technology

Where to Find Assistive Technologies?

The European Assistive Technology Information Network (EASTIN) provides a European search engine on Assistive Technology, working in all languages of the European Union.

The Unified Listing provided by the Global Public Inclusive Infrastructure (GPII) allows you to search twelve databases of assistive technologies and other accessibility solutions.

The page ATDatabases in the GPII wiki contains a list of databases of assistive technologies. The page was last updated in April 2015.

AsTeRICS

AsTeRICS stands for “Assistive Technology Rapid Integration & Construction Set”. It is a free and Open-Source construction set for assistive technologies (AT). It allows the creation of flexible solutions for people with disabilities using a large set of sensors and actuators. The project's source code is available on GitHub (licences: LGPL for some libraries, MIT or GPL with CLASSPATH exception for some other parts).

ACAT

ACAT stands for “Assistive Context-Aware Toolkit”. It is an open source platform developed at Intel Labs to enable people with motor neuron diseases and other disabilities to have full access to the capabilities and applications of their computers through very constrained interfaces suitable for their condition. The ACAT installer and the source code were first released on 23 April 2015 and can be donwloaded from the ACAT releases list on GitHub. The project also has a GitHub repository (licence: Apache 2.0).

ACAT was originally developed for the English physicist Stephen Hawking, who has ALS. For articles about this, see the following links:
