What smart glasses can do?

Smart glasses represent a significant leap in wearable technology, merging the connectivity and functionality of smartphones and computers with eyewear. Here’s an overview of what smart glasses can do.

  • Connectivity and Imaging: Smart glasses bring wireless connectivity and imaging, akin to smartphones and computers, into eyewear, allowing users to enjoy similar versatility and connectivity​​.
  • Sound and Communication: They typically feature speakers for wireless audio and cellphone reception, using bone conduction for sound transmission. There’s also a built-in microphone for phone conversations and voice commands, which can be paired with a micro speaker for audio feedback, music, and podcasts​​.
  • Visual Display: Smart glasses employ projectors and prisms (or alternative technologies like waveguide holographic optics) to create partially transparent digital displays that overlay text and images within the user’s field of view without obscuring real-world visibility​​.
  • Control Methods: They can be controlled in various ways, such as touch, tap, swipe on the frame, voice commands (similar to interacting with Alexa or Siri), gesture recognition, eye tracking, and even thought control in some advanced models​.
  • Adjustable Brightness: Some models use liquid crystal technology to filter brightness levels, enabling users to control the amount of ambient light and optimize the visual overlays of the smart glasses, potentially making sunglasses unnecessary​​.
  • Stylish Designs and Pricing: Modern designs focus on a sleek, stylish appearance, moving away from the geeky look of earlier models like Google Glass. This design shift has also influenced the pricing of these devices, making them more accessible​​.
  • Augmented Reality Applications: Future models, like the Facebook and Ray-Ban collaboration ‘Orion,’ are expected to use augmented reality (AR) to live-stream digital images and incorporate voice control, potentially replacing smartphones​​.
  • Other Developments: Companies like Apple and Bose are exploring combinations of virtual and augmented reality, integrating sound-based AR, motion sensors, and GPS for applications like real-time navigation and virtual tours​​.
  • Integration with Existing Technology: Amazon’s Echo frames integrate Alexa into prescription eyeglasses, allowing users to receive voice responses, set reminders, and control smart home devices on the go. These glasses also feature filters to manage the notifications received via the eyewear​​.
  • Challenges and Considerations: The introduction of smart glasses brings challenges such as the need for public education on their operation, maintaining the primary function of vision correction, ensuring safety (especially while driving), addressing security and privacy concerns, and overcoming fashion-related obstacles​​.

As technology evolves, smart glasses are set to transform how we interact with digital information and the world around us, offering a blend of convenience, connectivity, and enhanced visual experience. Issues on Smart Glasses Technology Adoption.
