> A web based heart rate monitor that measures pulse from the fingertip using the phone camera. It works the same way as many camera based heart rate monitor apps, but it works entirely in the browser so nothing needs to be installed on your phone.
Fantastic!
Neat! Possibly you already know this but "pitch detection algorithm" would be a good search term for looking for alternatives to zero-crossing or FFTs.
Thanks! I sort of assumed that pitch detection would just be FFT so I haven't searched for that yet. I'll take a look, it sounds like it could be the sort of middle ground that would be ideal for this.
This is such a fantastic example of what’s possible in the browser. Awesome work!
