Acknowledgements

I would like to thank my tutor, Javi Agenjo, for his guidance and inspiration in every step of this project, he spent a lot of his time, and the proof is our long email conversations. And my supervisor, Josep Blat, always making time to help me with my doubts regarding the elaboration of the Github documentation and the memory, teaching me to see the forest and not just the tree.

I would like to acknowledge all the GTI members whose advice and support guided me in these months. Especially three of them: Bea Cabrero for being direct, clear, and teaching me that 'Informality doesn't justify not using the tools at your scope' and Miquel Floriach and Victor Ubieto always with time to help me and very collaborative.

Special thanks to Jasmina Casado, without you, I'll have never known that I could do the practicum with the GTI.

I am also grateful to my best friends Krississ and Toni, who gave me a lot of feedback, ideas and moments of happiness. And my closest friends Raromo, Aina and Nestor, continuously listening and helping me. All of them always available to be testers in my inventions.

I very much appreciate my family support along these months of hard work.

And finally, but not least important, thanks to a small and chubby gerbil called Dixie, you were the best rodent in the world, bringing us so great moments that we will never forget you and your sister Pixie, who was more like an angry gremlin, but despite this, we also love her.
