This past week I worked on getting better, more accurate results from the stress monitoring system. I conducted a study with help from 7 participants to test the stress detection monitor. The experiment consisted of each subject watching entertaining youtube videos for a number of minutes followed by watching a stress-inducing video for a number of minutes. The goal of the study was to primarily test a hypothesis of a correlation I discovered when testing the system on myself. There's an apparent drop in the RR interval value, the time interval between heartbeats, when a user inhales. This allows me to detect an approximate respiratory rate on a stationary subject. The study was also useful in providing data for a range of individuals. At this point, the data looks promising. Obviously I'll need to do more work, perhaps another study of sorts, but what the monitor is reporting, if not actually detecting stress, at the very least has a high correlation with stress. Notable files include StressDetectorActivity.java
