intel/acat

Official release of ACAT is available here

Background

The Assistive Context-Aware Toolkit (ACAT) is an open-source platform created at Intel Labs. It is designed to enhance communication for individuals with restricted speech and typing capabilities. It achieves this by providing functionalities like keyboard simulation, word/sentence prediction, and speech synthesis.

ACAT was originally developed by researchers in Intel Labs for Professor Stephen Hawking. He was instrumental to the design process and was a key contributor to the project design and validation. After deploying the system to Professor Hawking, Intel turned its attention to the larger community and continued to make ACAT more configurable to support a larger set of users.

By making this configurable platform open source, the goal is to encourage developers to continue to expanding its capabilities by adding new user interfaces, new sensing modalities, language prediction, and other features.

ACAT is developed in C# using Microsoft Visual Studio* 2022 and .NET 4.8.1. It runs on Windows® 10 (20H2 or higher) and 11.

Versioning

The master branch on Github will always contain the most recent release of ACAT.

The dev branch contains commits from the ACAT development team towards upcoming releases of ACAT. Do not clone the dev branch as it has changes that are still in flux and the solution may not be stable.
