Imagine a pair of glasses that could tell you the name and address of anyone you met. Harvard University students Caine Ardayfio and AnhPhu Nguyen made them a reality in just four days.

The students adapted Ray-Ban Meta smart glasses and computer software to create spectacles utilizing existing face recognition technology to identify people in real time, underscoring the potential for augmented reality (AR) in future.

The glasses were able to deliver someone's name in just under two minutes using an existing public facial recognition search engine and artificial intelligence. This has raised concern about the unforeseen risks of AI and mixing of existing technologies.
