In its relentless drive to bring everyday items to customers faster, Amazon has shifted expectations from two-day delivery to same day and even within an hour. Now, with robots, artificial intelligence and even eyewear, it is working to pare seconds off each delivery. On Oct. 22, Seattle-based Amazon showed off advanced eyeglasses for delivery workers for the first time publicly. Known internally as Amelia, the glasses have a small screen that gives turn-by-turn directions, scans package codes and takes photos for proof of delivery.

The glasses could replace the bulky handheld Global Positioning System devices drivers currently use and give helpful navigation tips like which way to turn when leaving an apartment elevator or how to avoid an aggressive dog at a customer’s home. The announcements made at Amazon’s annual “Delivering the Future” logistics event are part of the firm’s particular focus on the “last 100 yards,” which contribute to the expensive final steps in a delivery’s journey to customers.
