 My name is Rafael Silva. I'm co-founder and developer at Ludwig. We started Ludwig next, please. We started Ludwig. Actually, it was like a coursework. We were for developers trying to make the difference. And basically, we had a passion developing end music. So we created this new experience. And why we do it? Basically, music is something that transforms us. It has power to change our emotions and to modulate it. So we realize that some people don't have that at all. And with that in mind, we started looking for new ways of experience music. And with that, we created a new experience that we combined colors and vibrations so people can really understand what they are experiencing instead of just giving random vibrations and random colors. So we started creating a new experience so people can start to interact in a different way. And our goal in the future is actually teach deaf people music. So we started late 2013. And we started researching about how could be possible for deaf people to understand music, to know what music really is. And we took some time researching and starting to make it possible. And when we realized that could be made, we started testing. Ludwig is like a result of another app that was just made for testing concepts and understanding what we were doing. So we started testing if the person could tell the difference between two vibrations, if the person could link a vibration with a color, and if a person could really understand that there's been a difference of vibrations and what a song is if the vibration does not annoy the person. So we started trying that out. And in this test, we met a guy that made us realize that we were in the right way. He's deaf and he comes from a musician family. So imagine that. You have all your parties, all your moments in family. And in his family, it was all about music and everyone like playing, everyone like dancing and stuff like that. But he was always out of that. So we always have music. We always have everything all the time. And sometimes we don't even realize that music is so good for our lives because we haven't stayed like a single moment out of it. So with that in mind, we really are struggling to create this digital method and a way of including everyone into the music because we really believe that music has a transformation power and it can actually transform it to us. Because actually, we don't know what that can result. Imagine we have the sign language. We have to learn to talk to deaf people. But music, by itself, it's a universal language. You don't need a translator to get that. You just listen to it. You just experience it. But imagine if a deaf person can create, make something unique, a song, and everyone here in this room can listen to it and see and understand what they were feeling. And we can translate this kind of work. We are going to break a barrier of communication. And that's our goal. Next slide, next slide. So basically, we are linking together vibrations and colors. So the brain of a person that doesn't hear, it's awesome. They are totally sensitive to the visual field and the tactile field. So it's impressive how they can learn and they can relate the vibrations and colors and actually start to understand that. Next slide. Our team is small. We are in four people. But we are working really hard to bring it to reality. And next slide. We really appreciate the time. And we really want to be here another time with a deaf person that could really tell by herself or himself like how it is to experience music in that way, the different way we are not used to. But showing that it can actually transform lives and change how we are used to. Thank you.
