On a chilly evening last year, a young man who had just returned from a weekend of camping in the north of France began to notice something unusual: there were more light-colored posters on the walls of his office than usual.
A few days earlier, in November 2016, he had been working on a project with a team of students from École Polytechnique in Marseille to design and manufacture light-sensitive displays for smartphones and other devices.
In the evenings, the students would often take turns working on different projects.
On one night, a colleague was painting the posters.
“It was like a real painting,” he said.
“They were really interesting and it made me think, why aren’t we using this?
Why aren’t people using this technology?”
And so he started the experiment.
The students would make up some sort of prototype for the display, then paint the walls and ceilings in various shades of light blue.
As he painted, the student would record the progress.
He would upload the footage to his website and upload the video to YouTube.
Soon, the videos had thousands of views.
One student even took the camera with him to Paris and used it to take photographs of people using the devices.
“I got a lot of people who wanted to help me,” he told the newspaper.
“And I felt very good.
One of the students who participated in the project, Emmanuel Nacional, said he felt lucky because “the project was really good.” “
People were helping me, they were buying things, and I was very happy about it.”
One of the students who participated in the project, Emmanuel Nacional, said he felt lucky because “the project was really good.”
He said he wanted to share his work with others because he felt he could be useful.
He even asked the students to take a selfie with their device on a wall.
Nacial’s students said the project “gave me a sense of belonging and I had a feeling of community”.
And he added that the “instruction of this project has made me a lot happier”.
But it was also important for Nacionnt to keep the experiment going for another few months.
In his research, he was also keen to find out whether the project was working.
“We found that it is possible to make a product which uses less energy,” he wrote in an email.
“The result is that the device is lighter, but at the cost of less power consumption.
Nacimal said he hoped the project would inspire people to look into light-sensing technology for their own devices. “
In addition, it was the result of an experiment that we did to see whether it could be used as a platform for new ideas.”
Nacimal said he hoped the project would inspire people to look into light-sensing technology for their own devices.
The student said he didn’t think it would be possible to put an end to the light-based display experiment anytime soon.
“Light is a very powerful thing,” he explained.
“But there are also some problems.”
“We need to continue using light,” he added.
“There are some other ideas out there that can be used.
I hope that these people will do their own experiments.”
But for Nakon, who also works on an artificial intelligence project at Écoles Polytechniques, it wasn’t just about the potential for the device to be used for energy.
The project “seemed like a nice way to start to look at the idea of using light as a substitute for batteries”, he said, adding that the students and he “took a few minutes to do some thinking”.
It was not an easy project to pull off.
“If you think about it, light is a light,” Nacions wrote.
“Batteries use light, but they also need electricity.
So I wanted to make it a system that can actually make use of light as the energy source.”
“There is still some work to be done,” Nafionnt concluded.
“So it’s a long process.”
