Hernan's thesis says there are different ways in which we can see or imagine different technologies.

His goal with the project is to make the invisible visible.

The first thing Hernan did was create a device that measures the signal strength of Wi-Fi and translates it to a sort of heatmap of colors.
So red represents the strongest signals and blue represents the weakest.

The device works similarly to your smartphone or computer, as it detects nearby Wi-Fi and lets you know how many bars of strength it has.
Then he used long-exposure photography to capture the ghostly images of the colorful Wi-Fi signals.

He makes different shapes by moving his device in different ways across the scene he's capturing.
He'll move the device around his body to see how the signals interact with it.

In a recent exhibit of his work, Hernan also hung up smartphones that ran an app that displayed different colors based on the strength of the surrounding Wi-Fi signal.
The color changes as the Wi-Fi gets weaker and stronger.

And they also emitted different sounds when the strength level changed.
Now that he's got the imagery down, Hernan is thinking about ways he could represent wireless signals through sound.

"We know certain spaces have strong signals, certain have weak signals, and we kind of modify our behavior based on that, and I think there are different opportunities to use these signals to interact," Hernan said.
That's my end goal, creating a new way to think about these technologies.
