However, the challenges facing Meta and other companies developing smart glasses are numerous. One of the biggest hurdles is typing. Smart glasses do not have keyboards, and users will need to find alternative ways to input information. Meta's VP of product, Li-Chen Miller, believes that using smart glasses will be a more natural experience than using a phone. Users will be able to talk, gesture with their hands, and look at things to navigate the device. For example, users can use voice commands, hand gestures, or even gaze-based interactions to control the device.
