Recently, Yann Lecun, director of artificial intelligence research at Facebook and artificial intelligence scientist, said in his speech that AR development is still challenging. Ar glasses will bring challenges to AI learning and involve a series of unsolved problems.

Perfect ar glasses are small, but still need to combine conversational artificial intelligence, computer vision and other complex systems. Therefore, glasses devices must use low-power artificial intelligence chips to ensure battery life and allow users to wear and use them for a long time.

This fall, Facebook has confirmed that it plans to launch ar glasses by 2025. “It’s very challenging for the hardware level, because the camera on the glasses tracks your visual information in real time with variable delay, so when you move… It will require a lot of computing processing. You want a voice assistant to communicate in real time, and you also want a motion (recognition) assistant to track hand movements in real time,” Lecun said. “Although real-time hand tracking technology has emerged, we still don’t know how to add it to small, low-power devices and be compatible with AR glasses. In terms of power and power consumption, performance and shape factors, this is really beyond our ability today, so you must make a breakthrough. For example, neural network is an option.”.
