Whether you kjøpe briller på nett or get them from your eye doctor or from different eyewear shops, the main function of an eyeglass is to better and correct our visual acuity, and this had been the main purpose since early years. Today, makers of eyeglasses and internet innovators are making collaborative efforts to transform our regular eyeglasses to something “smarter.”
What are smart glasses?
Essentially, smart glasses are an effort to put in the technology of wireless connectivity as well as imaging that we have and experience using our computers and smartphones into the lenses and frames of our eyewear.
The concept was first launched in 2013 by Google with the presentation of Google Glass Explorer, with the hopes to establish and boost the popularity of wearable wireless gadgets and devices such as smart watches. However, the Explorer was demonstrated to be overly geeky, uncomfortable as well as pricey, which after 18 months pushed Google to take it out of the market.
How do smart glasses work?
Google Glass, although they were pulled out from the market, has shown a worthy model of smart glasses that other tech companies would improve and perfect. Below are the features that Google Glass has placed into their smart glasses:
- Sound and Audio: The wireless speaker for audio inputs as well as the mobile phone reception are placed on the tips of the ear rests. Audio is transmitted to the ear through bone conduction rather than air conduction via the audio canal.
- Mic: The mic for phone conversations as well as for hands-free voice search is placed underneath one hinge. Today, majority of smart glasses with a mic are accompanied by a micro speaker for notifications and audio feedback and to listen to podcasts and music.
- Central Processing Unit: The CPU, or the brain of the computer, is placed on one of the ear rest.
- Camera: Although an evident feature in today’s selfie era, the lens of the camera which is located at the front of Google Glasses caused an inadvertent issue – privacy concerns. Many weren’t pleased to the idea of being pictured and filmed without their consent, a feedback that might have accelerated the retreat of Explorer.
