Intel unveils button-size wearable computer

Intel CEO, Brian Krzanich showed off a minuscule computer, dubbed Curie, during a keynote speech at the International Consumer Electronics Show in Las Vegas on Tuesday, January 6, 2015.

Krzanich plucked a button off his blazer before explaining that it contained a Curie demo module.

Curie is a sure sign that hardware makers are eager to build wearable devices of all kinds. It also points to the unwelcome size of many existing smart watches and smart glasses.

Intel's new device will include a Bluetooth low-energy radio, motion sensors, and components designed to rapidly and precisely differentiate between different types of physical activity. Krzanich said Curie will run "for extended periods of time" on a coin-size battery and would be available in the second half of the year.

Curie appeared much smaller than a postage-stamp-size computer, called Edison, that Krzanich showed off at last year's CES.

The world's largest chip maker evidently sees wearables as one of the most important categories in consumer electronics. It's a belief held by a lot of other companies at CES, where gadgets meant to be worn on the body or clipped to clothing were all over the show floor this year.

To make it clear that Curie is already functional, the company built a simple step-tracking smartphone app to go with the module Krzanich had on him; at one point he pulled the phone out of his pocket, and its display indicated he'd taken 1,788 steps during the keynote.

As part of its wearables push, Intel has partnered with a number of companies in the fashion and accessories businesses, including Luxottica Group, which is the world's largest eyeglass maker with brands such as Ray-Ban and Oakley. Krzanich said Luxottica will use Curie to make "truly consumer-friendly" smart glasses—a notoriously tricky thing to do, in part because of the size of components needed to make them work.

Oakley CEO Colin Baden joined Krzanich on stage to talk about wearables, which Oakley has built in the form of devices like ski goggles that include a head-up display. When you put a wearable device on your face, Baden said, it becomes part of your personality. "It's important the form factor compress so the electronic component of it doesn't become burdensome," he said.
