Many onlookers weren’t thrilled to in essence be filmed and saved without their permission, a reaction that may have hastened Explorer’s departure. The digital overlay of text and images within our field of view is the key that unlocks the smart glasses experience.Ĭamera: While an obvious feature in our selfie age, the camera lens at the temple of the Google Glasses brought with it an unintended new experience: privacy concerns. Some manufacturers now offer an alternative version called waveguide holographic optics. Projector and Prism: Located above the upper part of the lens, this projection method, called curved mirror or curved mirror combiner, offers partially transparent digital displays without obscuring the real-world view. Most smart glasses today pair the microphone with a micro speaker for audio feedback and notifications, as well as to listen to music and podcasts. Mic: The microphone for cellphone conversations and hands-free voice searches is perched under one hinge. Smarts: The central processing unit (CPU) computer brain is situated on the arm of one ear rest. Audio is transferred to the ear via bone conduction instead of air conduction through the audio canal. Sound: The speaker for wireless audio inputs and cellphone reception rests on the end of the ear rest(s).
Here’s how Google Glass slipped the smarts into smart glasses: Google Glass, however, proved a worthy smart glasses archetype that other tech players would soon refine.
