Snap partnered with chipmaker Qualcomm and OpenAI’s ChatGPT to create the AR Spectacles, which allow users to place digital images and filters onto the real world through the lenses.

Snap’s latest generation of augmented reality Spectacles have been lambasted by one of the engineers who helped to create them. The glasses, revealed earlier this week, were described as “a disaster” by Sterling Crispin, a former design engineer for Snap.

Snap announced an upgraded version of its Spectacles augmented-reality glasses on Tuesday, doubling down on its bet that wearable devices to enhance the view of the real world will be one of the next frontiers in tech.
