Comment on Why Snapchat making augmented reality glasses isn’t that bad an ideaparent

Comments

I've never heard of LIDAR before, will check it out.

Why is it 5 years from commercialization?

5 Years is probably generous.

1. They are only now being shown in R&D to be possible to make small enough for consumer devices. How do produce at wide scale is unknown and how they would be implemented in a stack is unknown.

2. It's unclear if the market is there for applications that need LIDAR over more proven IR or cheaper CV techniques.

3. FCC requirements are a pain for active sensors like LIDAR or Ultrasonics on consumer devices
