Finally the Assistive Context-Aware Toolkit (ACAT) developed from Intel is available as Open Source!! It is actually used for Stephen Hawking: “ACAT is useful for Microsoft Windows developers who are interested in developing assistive technologies to people with ALS or similar disabilities. Also for researchers who are working on new user interfaces, new sensing modalities or word prediction and wanting to explore these innovations in the this community.”, it’s made available under the Apache-Lizenz Version 2.0.
More information is on the website: https://01.org/acat.
This is great because the software was not publicly available over ten years – now everybody can use it!!
