A third party, Vuzix [wikipedia.org], will use Amazon's Alexa service to deliver information to its augmented reality glasses [bloomberg.com]:
The first augmented-reality glasses with Amazon's Alexa voice assistant will be shown next week at CES in Las Vegas -- manufactured by a 75-employee company rather than the e-commerce giant's growing devices division.
Vuzix Corp. will show off a pair of smart glasses that can talk to Amazon.com Inc.'s voice-activated digital assistant and display information to the wearer's field of view, Vuzix Chief Executive Officer Paul Travers said in an interview. Vuzix's Alexa integration is part of an Amazon program that allows third-party hardware manufacturers to put the digital assistant into their products. In October, Sonos Inc. unveiled a smart speaker with Alexa's system for controlling music playback. The strategy is designed to put Amazon's service, which generates revenue for the company, in as many places as possible to sell more products.
[...] Vuzix [vuzix.com] will release its AR glasses by the second quarter at a cost of about $1,000, Travers said. While it's a "high price point," he said, "the ultimate goal is to have it under $500, and we'll be able to do that" by 2019. Wearers, who must be Amazon customers or become Amazon customers to enable Alexa's capabilities, could for example ask the digital assistant to pull up a map or display sports scores on the glasses.
Amazon hasn't said whether it will release its own branded smart glasses with Alexa, but Travers expects it to happen. "I think everyone is going to come out with glasses sooner or later," he said.
