The famed author and physicists relies on the technology to speak, as well as perform other basic functions like browsing the internet. Hawking, 73, suffers from motor neuron disease, or Leu Gehrig’s disease, which has left him almost entirely paralyzed. Intel hopes that it can assist others with similar disabilities. Code for the software, called [Assistive Context-Aware Toolkit](https://01.org/acat) (ACAT), is available to developers for free. By open sourcing the program, Intel believes developers will innovate and expand on the base system. Hawking got an upgrade from the computing giant last year, increasing the efficiency of his system. ACAT’s upgrade works much like the predictive type features on an iPhone, allowing the software to guess what Hawking is trying to say based on what he’s already typed.
