How did they come up with this idea?

During this rainy season, a new invention has caught people's attention that seems incredibly useful.

A man is walking, and an umbrella is following right above his head.

It is fascinating to see it move in sync with him without being held by hand.

This is the so-called 'hands-free umbrella' that follows its user automatically.

Created by a technician in Canada, the umbrella is equipped with four propellers, one on each side.

By integrating GPS and cameras, it analyzes the user's location in real-time, and a flight control system adjusts the propeller output to keep the umbrella following the user.

However, it is reported that this is currently in the technical testing stage and is not yet a product ready for commercial use.
