Today, many Australians who need AAC still lack access to the technology and the support they need to use it. AAC includes sign and gesture systems, communication boards, speech-generating devices, mobile phones with apps, and even emojis and social media. Ultimately it works not only through the interaction of the user with their device, but also through their interactions with communication partners.

Some AAC systems are non-electronic , like communication boards, books, or wallets for people to point to or look at letters, words or phrases to communicate. Apart from the time taken to compose a message, it can take hours to program what could be spoken using a communication aid — and many more to ensure that the desired words can be found just in time for communication.
Hawking used a switch to control software on a computer that enabled him to talk. Denman thought they were on the right path. By September, they began to get feedback: Hawking wasn't adapting to the new system. It was too complicated. Prototypes such as the back button, and the one addressing "missed key-hits," proved confusing and had to be scrapped. We were trying to teach the world's most famous and smartest year-old grandfather to learn this new way of interacting with technology. Denman and the rest of the team realized that they had to start thinking differently about the problem.
We had to point a laser to study one individual. At the end of , the Intel team set up a system that recorded how Hawking interacted with his computer. They recorded tens of hours of video that encompassed a range of different situations: Stephen typing, Stephen typing when tired, Stephen using the mouse, Stephen trying to get a window at just the right size. By September , now with the assistance of Jonathan Wood, Hawking's graduate assistant, they implemented another iteration of the user interface in Hawking's computer.
However, by the following month, it became clear that, again, Hawking was having trouble adapting. It was many more months before the Intel team came up with a version that pleased Hawking. For instance, Hawking now uses an adaptive word predictor from London startup SwiftKey which allows him to select a word after typing a letter, whereas Hawking's previous system required him to navigate to the bottom of his user interface and select a word from a list. In the beginning he was complaining about it, and only later I realized why: He already knew which words his previous systems would predict.
He was used to predicting his own word predictor. Selecting 'black' automatically predicts 'hole'. The new version of Hawking's user interface now called ACAT, after Assistive Contextually Aware Toolkit includes contextual menus that provide Hawking with various shortcuts to speak, search or email; and a new lecture manager, which gives him control over the timing of his delivery during talks.
It also has a mute button, a curious feature that allows Hawking to turn off his speech synthesizer. He does it all the time and sometimes it's totally inappropriate. I remember once he randomly typed 'x x x x', which, via his speech synthesizer, sounded like 'sex sex sex sex'.
Wood's office is next to Hawking's. It's more of a workshop than a study. One wall is heaped with electronic hardware and experimental prototypes.
Mounted on the desk is a camera, part of an ongoing project with Intel. You can read it here. Well, here's how To feed information into his computer, Hawking used an infrared switch mounted on his spectacles that caught the slightest of twitches in his cheek. Source: EE Times Along with talking and writing, the software also let him check his email, browse the internet, chat on Skype and make notes.
The software was updated frequently to help him cope with the gradual loss of control over his muscles. The program also allowed him to move a cursor around the entire computer giving Hawking access to email, a word processor an even video chatting, said Hawking's website. That software can be used by anyone with a disability that makes using a traditional computer difficult. Newsweek magazine delivered to your door Unlimited access to Newsweek.
