Wearable computers could augment memory by reminding the wearer of people's names upon entering a room or notifying them of upcoming meetings, providing immediate access to important data for mobile workers like doctors and first responders. Early prototypes included augmented reality glasses that displayed information to the wearer through integrated screens and responded to voice commands, with potential applications including facial recognition and image processing. Future users may more widely adopt wearable computers for note-taking in various professions or unique applications that overlay digital information onto a live video feed.
