Smart glasses

Smart glasses or smart glasses are laptop glasses that aggregate information next to or alongside what the user sees. Alternatively, smart glasses are sometimes referred to as laptop glasses that can change their optical properties at run time. Smart sunglasses programmed to change color electronically are an example of the latter type of smart glasses.


The overlay of information in a field of view is achieved via a head-mounted optical display (OHMD) or wireless glasses integrated with a transparent head-up display (HUD) or an augmented reality (AR) overlay. These systems have the ability to reflect projected digital images and also allow the user to see through them or see better with them. While early models can perform basic tasks, such as serving as a front display for a remote system, as is the case with smart glasses using cellular or Wi-Fi technology, modern smart glasses are effectively laptops capable of running mobile applications. . autonomous. . Some are hands-free and can communicate with the Internet using natural language voice commands, while others use touch buttons. [5] [6] [7] [8] [9]

Like other computers, smart glasses can collect information from internal or external sensors. You can check or recover data from other tools or computers. It can support wireless technologies such as Bluetooth, Wi-Fi and GPS. A small number of models run a mobile operating system and act as a portable media player to send audio and video files to the user via a Bluetooth or WiFi headset. [10] [11] Some smart glasses models also have activity log and activity log capabilities. [12] [13] [14] [15]

Devices with smart glasses may also have functions found on a smartphone. [16] [17] Some have activity tracking features (also known as “fitness trackers”) as seen on some GPS watches.
Features and applications
As with other life tracking and activity tracking devices, the GPS tracking unit and digital camera in some smart glasses can be used to record historical data. For example, after completing a workout, the data can be uploaded to a computer or online to create an exercise activity log for analysis. Some smartwatches can act as full GPS navigation devices, displaying current maps and coordinates. Users can “mark” their current location and then change the entry’s name and coordinates, allowing navigation to those new coordinates. [20] [21]

Although some smart glasses made in the 21st century are fully functional as standalone products, most manufacturers recommend or even require consumers to buy mobile phones with the same operating system so that the two devices can be paired for additional functionality. has improved. The smart glasses can function as an extension, for the front view (HUD) or remote control of the phone and alert the user of communication data such as calls, SMS messages, emails and calendar invitations.

Security app
Smart glasses can be used as a body camera. In 2018, Chinese police in Zhengzhou and Beijing wore smart glasses to take photos that are matched against a government database that uses facial recognition to identify suspects, retrieve an address, and track people moving beyond their areas. originally.

Healthcare applications
Various proofs of concept have been proposed for Google glasses in healthcare. In July 2013, Lucien Engelen launched an investigation into the usability and impact of Google Glass on healthcare. Engelen, which is based at Singularity University and in Europe at Radboud University Medical Center, [25] participates in the Glass Explorer program. [26]
