Putting Alexa inside a pair of smartglasses makes a lot of sense

Vuzix has been a regular at CES for years, crafting head-mounted displays and smartglasses often aimed at businesses -- or very enthused wearable fans. The Vuzix Blade, its latest pair of augmented reality spectacles tries to balance that B2B / consumer sales pitch by adding a voice assistant. Amazon Alexa's newest home is a pair of smartglasses. Firstly, the crush of a CES evening show is never the best place to test out a voice assistant: you need a strong connection to make her receptive to your requests. So, pretty much all my Alexa queries fell on deaf robot ears.
