About Me? Not An Artist>>>>
Are you sure you want to know about me? Then here I’m, Mayur Koli, an Indian student. I love to learn, get experience. I’m also an art lover as you can see. Okay, I think it’s enough. One more thing, i'm not the person in the blue goggle.

A man turns Wi-Fi signals into beautiful colors and captures ghostly pictures

It’s hard to believe that the thing we are always surrounded by, the Wi-Fi signals, can look so creepy like this. 

Luis Hernan is an artist that has been so curious about finding a way to show the wireless which is around us and how it changes.

He did architecture, computer science and design; but his interest made him to be a PhD candidate at Newcastle University to make the invisible visible.

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

Firstly, what he did was a device called Kirilian which measure the strength of Wi-Fi signals and translates it to different colors that lights up based on the strength of signals.
His goal with the project is to make the invisible visible.

His project Digital Ethereal includes a system that turns signals into certain beautiful trails of light. So red color means the strongest signals and blue the “weakest”.
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.

Then he photographed these ghostlike movements using his long-exposure photography. And the results documented are so colorful.
So red represents the strongest signals and blue represents the weakest.

The different shapes are captured by moving the device in different ways.
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.

Recently, in his exhibition, he also allowed people to see the strength of signals changing constantly by hanging up plenty of smartphones while running an Android app based on the Kirilian Device.
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.

And here is yet another interesting thing about this app, it also emits various sounds when the display takes a change in color.
The color changes as the Wi-Fi gets weaker and stronger.

He'll move the device around his body to see how the signals interact with it.

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.

"I was very curious about this idea of the invisible signals that surround us all the time so I wanted to explore that," Hernan told Business Insider. "I was really interested in how they would look if we were able to see them."
That's my end goal, creating a new way to think about these technologies.

“Close the wrong door, and the bedroom becomes a dead spot for wireless.”
