Chipmaker Intel is developing technology to improve the speaking system used by renowned physicist Stephen Hawking, who has a degenerative illness that has taken a toll on his ability to communicate. According to Intel Chief Technology Officer Justin Rattner, the company is building on an earlier method that allowed Hawking to compose words using a voluntary facial muscle twitch. The new system, which will use cheek, eyebrow and mouth movements to generate computer impulses, is part of a broader Intel program to advance smart devices to help the elderly.
