Lost in a new city? Aya needs the train station. She wears smart glasses. These are glasses with a small computer. Aya asks a man for help. He speaks a different language. The glasses translate his words. Aya hears, “Go past the bank.” Then, the glasses give walking directions. They say, “Turn left at the cafe.” Aya keeps her phone in her bag. Soon, she sees the station. Some smart glasses can translate and guide. But Aya still watches the road. New words can show the way home.
