A visiting French scholar, Olivier Andlauer, M.D., was trying to find polysomongram criteria to better streamline diagnosis of Narcolepsy in humans. We had several good conversations after an initial lab presentation of his where he outlined the project. I didn't understand the problem well, and he didn't know some of the computational solutions available. Our collaboration resulted in development of the softROC software and subsequent narcolepsy diagnostic criteria.
The narcolepsy publications are here:
The softROC software is available here or from the links on the left.
This manuscript is essentially a summary of my Master's thesis. I would go walk circles at the 1/4 mile track wearing this $1000 sensor and see how close I could come after error correcting the double integrated accelerometer data. Nike came out with their in-shoe device and I couldn't believe they were doing the same thing so cheaply. Of course later on I figured out that they were actually just using a pedometer, which was not nearly as interesting.
I put a video together of this as well - adding it to the site is on the to-do.
