Hawking's computer system has enabled him to continue to write and speak. This computer, that has brought many of Hawking's ideas and lectures to life, is sponsored and provided by Intel Corporation. The computer system consists of a tablet mounted on the wheelchair, which is powered by Hawking's wheelchair, a speech-generating device, and a special infrared switch allowing him to control the computer with his cheek. Based on his cheek movement, Hawking can use the cursor to surf the internet, write books using an onscreen keyboard, or give lectures by feeding written material to the speech-generator. The computer's main interface is a program called ACAT, which was written by Intel.

    Hawking has also shared how amazed he is with the breakthrough in technology and its advantage to those with disabilities, including himself.
