"The concept worked, but you'd never wear it because it would be ridiculous," he added. The devices that he is talking about would be much smaller and lighter.

To get there, is working on computer chips that would be smaller than the company's low-voltage Atom processors, which power mobile phones and . According to Vara, the chips could be less than half, or even less than a quarter of the size of an Atom chip.

"With Atom, we're talking about 1 or 2 or 3 watts. With these it would be in the milli-watt range," said Vara. "These are being explored."

To help reduce the size and the power of these small chips, Vara said they probably would not have the instruction set normally found in a microprocessor.

"Potentially, it could have graphics built in," he said. "Right now, it's early in the game so we're looking at what makes sense to put in there. You'd want to have some memory built in, maybe some graphics because you'd want to have one chip ... maybe two chips but size-wise you want to keep it small."
