See the results here: https://guzey.com/science/sleep/14-day-sleep-deprivation-self-experiment/

This is the protocol for my sleep experiment that I will start on 2020-04-03. I will sleep 4 hours per night for 2 weeks and evaluate the effects of doing so on my cognition using psychomotor vigilance task (essentially, a reaction test), SAT (a 3 hour test that involves reading and math), and Aimgod custom scenario I called guzey_arena_0 (video) (this is a first-person shooter trainer game that allows the creation of custom scenarios. The scenario I created requires constant attention, eye-hand coordination, tactical thinking).

Methods

EMFIT Local API

There is a functional http server running on the device that can be crawled for realtime data. It runs on port 80 and uses plain http.

You will need to know the IP address if your emfit device.

shortdvm.htm

For demoing / testing with a web browser there is an auto-refreshing page that contains only HR and RR values, it’s name is shortdvm.htm

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.
