Apple Inc. is weighing an expansion into digital glasses, a risky but potentially lucrative area of wearable computing, according to people familiar with the matter. While still in an exploration phase, the device would connect wirelessly to iPhones, show images and other information in the wearer’s field of vision, and may use augmented reality, the people said. They asked not to be identified speaking about a secret project. Apple has talked about its glasses project with potential suppliers, according to people familiar with those discussions. The company has ordered small quantities of near-eye displays from one supplier for testing, the people said. Apple hasn’t ordered enough components so far to indicate imminent mass-production, one of the people added.
