Samsung may be developing foldable augmented reality glasses

In its initial stages, which may be subject to change later, the eyepiece automatically switches on every time it is unfolded. As long as one of the eyepiece's temples is unfolded, the glass's projector which is mounted on the temple will beam images on a small display which is placed over the wearer's FOV (field of view). 

To ensure that the device doesn't accidently turn off if the user turns their head wrong, the company may be utilising magnetic sensors that make sure the glasses remain in the unfolded position until the user manually folds them. 

However, there is a real possibility that the patent application may never go through, so Samsung hasn't discussed the exact components they intend to utilise. In case it does go through, they cited ARM-based processors as an example of the kind of tech the device might use.
