Coaster Fusion is a fully automated way to track, analyse, catalogue and re-live your roller coaster adventures.

Using 4D variational data assimilation methods developed in the atmospheric physics and climate modelling community, along with machine learning techniques, measurements from multiple phone sensors are fused to re-create the ride experience and other roller coaster statistics. All you need to do is place your phone securely in your pocket just before you board, and enjoy the ride. As soon as you disembark, you can then explore elaborate track recreations, detailed statistics and a complete semantic analysis of the ride experience.

Here are some example reanalysis outputs from our algorithm. These are based on real sensor measurements recorded on an iPhone with our prototype application. If these are viewed on a mobile device with a camera, you may experience and explore each of these models in an augmented reality environment.

As your catalogue of roller coaster tracks and credits is built up, lifetime statistics enable you to finally answer questions like “Which is the fastest coaster I’ve ever been on?“, “What is the greatest G force I have experienced on a coaster?” or “How much total time have I spent hanging up-side-down on a ride?”.

The assimilation algorithm and the platform are currently under active development and research. Get in touch if you want to learn more or collaborate! Sign up below with your email to get notified when there are new developments or when the application enters public beta.
