Another challenge is making the AR experience feel natural. The Verge notes in its hands-on review of the Orion smart glasses that Windows occasionally filled the entire glasses lens, completely obstructing the user's view of the world around them. To get there, Meta will need to improve its AI, typing, AR, and a long list of other features. The company will also need to address concerns about privacy and security, as well as the potential for distraction and addiction.
