Replacing smartphones with smart glasses isn’t practical … yet. In the meantime, advancements in photonics are helping to expand the use of smart glasses in educational, medical, military, and industrial settings.
According to technologists and end users, what’s needed to sustain and accelerate this growth are brighter light sources, more efficient delivery optics, and better eye-tracking sensors. Also on the wish list are systems with lower weight, more compact form factors, and reduced cost. These requirements apply both to virtual reality (VR) headsets that immerse users in a digital world and to augmented reality (AR) glasses or displays that superimpose digital data over real-world scenes.
