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. These are cool ideas but they won't be coming to completion any time soon. Another experimental project, suggested by the manufacturers of Hawking's wheelchair earlier this year, is a joystick that attaches to Hawking's chin and allows him to navigate his wheelchair independently.
Because he doesn't have neck movement it is difficult to engage and disengage the joystick. In it, you can see Hawking driving his wheelchair across an empty room, in fits and starts. It's a CallText , a model given to Hawking in when he visited the company that manufactured it, Speech Plus. A lot of people have a lot of questions about his wheelchair. So, today, we will explain how this special chair works. These were some of the important facts about the wheelchair of Stephen Hawking.
Let us know if you have more specific information on this topic. Thank you! November 13, Its computer, a Lenovo from China, used an American-made infrared sensor on his glasses to "read" his cheek movements. Hawking's voice was developed by Dennis Klatt, a US scientist who based it on his own speech. The "CallText " system based on Klatt's work delighted Hawking so much that he bought three - but when the last began failing, it was too old to fix.
Hawking had famously rejected all ideas of an afterlife. There is no heaven or afterlife for broken down computers; that is a fairy story," he said. He had been diagnosed with motor neuron disease in his 20s, which meant he spent much of his life in a wheelchair. For his friends and family the wheelchair was central to his identity, which would now most likely have an afterlife.
Usually, symptoms develop after age 50, and lead to death within a few months or years. So when doctors diagnosed Hawking with ALS at the extremely young age of 21, the predicted he would only live a couple of years.
Instead, he lived for 55 more years. But once he started, he was reportedly a pretty wild driver. Hawking is known for his theoretical contributions to science. In , he bet physicist Kip Thorne a Penthouse subscription that an astronomical object known as Cygnus X-1 was not a black hole.
