'Smartphone-Based Detection of Middle Ear Fluid'

'users download a smartphone application, through which they play a chirp of sound into the child's ear canal. The sound reflects off the ear drum and is picked up by the phone's microphone. A machine learning algorithm then interprets the sound and determines whether fluid is present. The only attachment needed is a small, easy-to-construct paper funnel.'

I've always wanted to be able to detect a child's "middle ear fluid"... would you like to detect how much wax there is with that...

yummy

A vast improvement over the "choose your own path" family-diagnostic books of my childhood.
With a few cheap tests a whole lot of childhood misery and death could be avoided and this seems like a step in the right direction.

EDIT: Never mind. Brain fart

Obviously, we don't have the technology to trust smartphone-based apps to diagnose cancer yet.
