Thanks to ESME Sudria Students, You Can Now Participate in the Tour de France from The Comfort of Your Own Home

  • 09/08/2016

Although exercise bikes are now used abundantly by people in the confines of their own homes, they are often frustrating and monotonous for those who are used to cycling outdoors. Addressing this issue, the company Cab2way has offered 5th year Digital Intelligence & Data majors at ESME Sudria the chance to create a simulator prototype composed of three 4-foot high, panoramic screens allowing for the recreation of an environment that can produce the same sensory stimulation as that experienced by outdoor athletes. These students have taken up the challenge by developing a model featuring a variety of immersive technologies (video/sound synchronization, GPS data, a fragrance diffuser, etc.) that are sure to charm your inner Christopher Froome. Who knows, soon you might just be riding in the Tour de France from the comfort of your own home!

A Look Back at the 2016 Symposium Awards Winners: Genblick

  • 18/07/2016

Among the dozen or so end-of-studies projects in competition at the 2016 ESME Sudria Symposium, only three had the honor of being awarded top prize by this year’s jury. Over the summer, the school invites you to re(discover) these three outstanding winners. After EEG Headset and WADA, it’s time for Genblick (“instantaneous” in German), the last of our winners, to take the spotlight. Elies Yangui (ESME Sudria Class of 2016), who alongside Basma Allam and Ismenia Marson completed this project, talks to us about the origins and features of their instant messaging application.

 

 

How did you come to work on this project?
The school gave us a choice of several different subjects for our final project. Basma, Ismenia, and I quickly decided upon this one (instant messaging) because it required implementing a new technology, even though the technology had already been used by large companies such as Google, Skype, etc.

What exactly is this “new technology?”
It’s an XMPP communications protocol created by Jabber which transmits instant messages – in other words text, audio, and video. What makes this protocol special is that it was quickly picked up by buyers upon being released in 2002. The reason for the enthusiasm lied in the fact that the protocol uses a domain name and thus allows you to set up your own server. Essentially, each company uses the same technology – that of the XMPP protocol – all the while having an individual server at their disposal. Previously, this kind of messaging passed through centralized servers: every company therefore had to “dig” in the same “computer pool,” which caused problems with respect to competition, security, etc. With the emergence of this protocol, anyone can now implement messaging from their own private servers. That’s exactly what we did with Genblick. The messaging, of course, can be set up in a number of different ways, with varying scope and power according to the infrastructure you have to start with. That’s why this protocol was something everyone could agree on, despite the fact it was so new. Incidentally, Facebook wasn’t especially fond of Jabber for political reasons and tried to implement its own XMPP server using a similar protocol base. But as of today, the company still hasn’t succeeded in doing so. This example shows just how much the protocol is the current reference.

How did you create Genblick?
Basically, all it took was setting up an XMPP server. We ended up using an existing server and tweaking it so it would work with ESME Sudria’s Wi-Fi. The idea was to implement and administer the server correctly, as it was the “backbone” of our project. Overall, we were extremely pleased with the speed and efficiency with which we completed this phase of the project. We therefore decided to embark upon another challenge: code our own “client” after having used existing clients to test our XMPP server. Roughly speaking, this meant coding our own application so it would be operational as quickly as possible. This phase turned out to be an even greater challenge…but one we were also able to meet head on!

 

 

In the end, what did you learn from this project?
To start with, it allowed me to work in a team and apply my newly-acquired knowledge in a hands-on manner. Before the project, we had learned and applied a multitude of subjects: network administration, Java development, the implementation of new technology, etc. If you look online, you certainly won’t find a lot of people who, like us, succeeded in setting up a functional application and XMPP server, which incidentally were done in Java! Android apps are easy to find, but Java apps? That’s a novelty. To realize we succeeded in creating a small-scale version Skype with a limited amount of resources was extremely gratifying. In some way, it shows that you can be an innovator even without working for Google, Apple, Facebook, or Amazon (GAFA)!

What does it mean to you to receive a Symposium Award?
It’s a source of pride, as well as an honor for the Images, Signals, and Networks laboratory and our supervisor, Mr. Eric Munier, who always encourages us to think outside the GAFA box. By the way, at one point the jury asked us what Genblick had that Skype didn’t. We responded by saying it didn’t have anything new, except that Skype was the fruit of a major corporation, while Genblick was created by just three students from a French engineering school. Finally, this prize is also a reward for all the ESME Sudria apprentices who, in the history of the Symposium, have not always had the chance to be laureates. This recognition means the world to us.

Is there a future for your project?
I think so, yes. We’d like to promote the open source aspect even further by creating a site that grants access to our code. Currently there is very little documentation on the subject. Such a site would therefore allow us to address the issue of promoting the project, as well as explain how to set up and implement an XMPP server. And that could eventually inspire others, including ESME Sudria students, to pursue the project from their own end.

A Look Back at the 2016 Symposium Awards Winners: WADA

  • 04/07/2016

Among the dozen or so end-of-studies projects in competition at the 2016 ESME Sudria Symposium, only three had the honor of being awarded top prize by this year’s jury. Over the summer, the school invites you to re(discover) these three outstanding winners. After EEG Headset, it’s time to shine the spotlight on WADA (Weather and DAMIR Analysis), a project by Anthony Ginoux and Erwan Le Covec (ESME Sudria Class of 2016).

Can you tell us in a few words about the project your team presented during the Symposium?
Erwan Le Covec: WADA is an introductory project to Big Data and machine learning that deals with the analysis of two types of data: health insurance data on the one hand, and weather data on the other. The idea is to see if the weather really plays a role or not in the data gathered by the health care system. For example, we often imagine the number of colds and respiratory infections rising when it is cold and rainy. With WADA, we can know for sure.

Why did you choose this project?
Erwan Le Covec: We were excited by the possibility of working with Hewlett-Packard Enterprise (HPE), the project’s corporate partner. We were confident that working with such a company was going to be a good experience. We were also interested in the technologies associated with the project: Big Data and data analysis are two fascinating subjects that we wanted to explore further.

How far did you get with the project?
Erwan Le Covec: We were able to perform all the analyses we wanted and came up with some pretty interesting results. The goal now is to continue to improve the communication between the machines within the infrastructure that was used.

A Look Back at the 2016 Symposium Award Winners: EEG Headset

  • 28/06/2016

Among the dozen or so final projects in competition at the 2016 ESME Sudria Symposium, only three had the honor of being awarded top prize by this year’s jury. Over the summer, the school invites you to re(discover) these three outstanding winners. We’ll start with the EEG Headset, a project by Amina Chenigle, Silvio Garnier-Gaume, and Quentin Plattier (ESME Sudria Class of 2016).

Can you tell us in a few words about the project your team presented during the Symposium?
Silvio Garnier-Gaume: Our final project concerned the conception of an EEG (electroencephalogram) headset that allows for the acquisition of cerebral activity, the processing of data stemming from this activity, and the subsequent control of a wheelchair by thought and eye movement.

Why did you choose this project?
Silvio Garnier-Gaume: This project was introduced two years ago by ESME Sudria graduates, who today are behind the creation of the startup Neuromoov. While working on their final project, they were able to validate the operating principle and create a functional prototype. The only problem they encountered involved the utilization of the data via the headset which was being used at the time. Last year, another group of ESME Sudria students, in partnership with Neuromoov, took over the project. But once again, they experienced problems. This time, the issues they faced were associated with a different headset and the encryption of the data that was being gathered. This was the context in which we began our project. From a technical standpoint, we found the challenge extremely exciting.

What were you able to contribute to the project?
Silvio Garnier-Gaume: We used an OpenBCI acquisition card, which thanks to the algorithm we developed ourselves, allows for the processing of the data stemming from the electrodes and the cerebral activity. Still using this card, we also developed a method that can recognize which way the user of the headset would like to move. Their concentration is used to identify when they wish to move forwards and backwards, while their eye movement determines when they would like to move to the left and to the right. To complete our project, we must now finalize the implementation on the microcontroller and create an entirely functional headset capable of establishing a Bluetooth connection with the electric wheelchair.
