For my final year project, I chose to create BBC Sleep. BBC Sleep is a dedicated app incorporating all that the archives and sounds have to offer to help the user achieve a better night sleep. Using machine learning and user input, we want to match the right sound to how you sleep. Tracking the users Circadian Rhythm and breathing the app learns and determines when the right time to play sound is. If the sounds chosen by the user makes them more restless, we play something unexpected to help, and in the morning, you can review.
