Google Glass and Augmented Reality (AR): Google Glass is a wearable smart device that was developed by Google. While not specifically a virtual reality (VR) device, it falls under the category of augmented reality (AR). Google Glass is a pair of smart glasses with an integrated heads-up display (HUD) that provides information to the wearer without obstructing their view.In the context of AR, information is overlaid onto the user's real-world environment. Google Glass allowed users to see digital information such as messages, navigation directions, and more, right in their field of vision. Although it didn't immerse users in a fully virtual environment, it marked an early attempt at integrating digital information with the real world through a wearable device.
VR Headsets with Glass Components: Another interpretation of "glass virtual reality" could refer to virtual reality headsets that use glass or transparent displays. Traditional VR headsets typically use opaque screens to immerse users in a completely virtual environment by blocking out the real world. However, some experimental or advanced VR systems may incorporate transparent or partially transparent displays to blend elements of the virtual and real worlds.Transparent displays could allow users to see their surroundings to some extent while still experiencing virtual content. This could be useful in applications where situational awareness is important, such as training simulations or certain types of gaming experiences.
