Audispensable - Défi H 2016




"The movie takes place in a quite and featureless world. It tells a story about a meeting of a young girl and a curious creature who creates the sounds. Together they break the silence of the world and they discover some extraordinary landscapes and the rythm of the music. The message comes at the very end : The creature is the made up personification of the kids hearing aid. She is deaf and, thanks to the aid, she just heard for the first time."

Everyone is busy preparing our models!

It all started with the creating of 3D models, thanks to the SketchUp software. We took some time to learn to work with the software, to consider the forms we want to give to the T-Jack, and then the drawings models were born! Several types, different sizes ready to move to 3D printing box!


The university Grenoble Alpes has a laboratory which is available for student projects. So we could use it for printing the models. In twenty minutes, T-Jack shells appeared in our hands. What a joy !



The next move was to fix Jack to the model! Lucille and Florian have applied the best in the laboratory of our school Polytech Grenoble.

The final step was the meeting of users to show them our work. It was their job to choose the shape and size then prefer. We will organize a new meeting to validate the selected T-Jack, so we really developp something the ftur user would appreciate.

Technology for Health and Autonomy Course (THA)


In the first half of the 4th year of our engineering program at Polytech Grenoble, we hada course of THA. At that time, it was requested that we imagine a project that would help elderly or disabled people in everyday life. We then recalled Matthew's issue! In a group, we brainstormed and at that time already, a tiny idea of ​​the T-Jack was making its way into our heads. We wondered how to develop a device that could solve this problem, what technology could be included, who would it be for?


The idea then had time to mature as it was accepted as a THA project by our supervisors. This was a collaborative and tutored work during an entire semester that allowed us to move a big step towards the realization of the tool. During courses at Polytech we had the chance to meet the professionals such as TASDA (Technopole Alps, Health at Home and Autonomy) which was very encouraging. They made us understand that it is possible to transform the students project into a real market oppurtinity and they gave us even more desire to feed our project.


We spent plenty of time doing research on the internet, but not only that! Indeed, from the beginning it seemed necessary to examine precisely the user needs to avoid falling into the common trap: Develop an unsuitable tool that will be forgotten and never used. We then approached the ARDDS38 Association (Rehabilitatio and Defence of People that became Deaf or Hard of Hearing) to realize if its members face the same problem that Matthew. We wanted to learn if they know how to bypass this problem. Since we have already imagined T-Jack, we asked if they would be interested in the use of such a tool. And then, bingo! They were delighted! One more point on the scale of our motivation!


At the time, the first defense of our work was done to our supervisors and we received more than a positive feedback: A very promising and valuable work that allows to dream of a useful and usable solution for the deaf and hard of hearing. We were encouraged to participate in next year's Challenge: the DéfiH to obtain the visibility and to work on the developpment of the tool to bring this solution available to persons with disabilities.

The first idea


The idea for this project came to us by observing deaf and hard of hearing persons around us. Precisely one of them, let's call him "Matthew." Indeed, Matthew never uses his mobile phone to call because communication is almost impossible, in any case highly unpleasant. And this even in a very quiet place. So if you want to join him, it is through SMS! That's not an issue if you need to tell his friend to get around and have a dinner with you, but it becoles something far more embarrassing when you must make a professional phone call for example. We also noticed that Matthew could not listen to music with headphones. The microphones of the hearing aid and cochlear implant are located behind the ears, so he needed to hold the headphones behind his ears. By observing him two minutes, it is clear that it is neither practical nor satisfactory solution.

But then, is there another solution?

History of the project 


Decision to participate in the Challenge DefiH


We send our application to Challenge DefiH 2016 and we await the results eagerly. This project begins to be very important to us, it'd be such an opportunity to continue ... Then the news came, we could continue for five more months!
