The Theater 2013 is an interactive horror experience based on a horror short story. If you’ve not played the game yet I recommend you download it and try it out. The game doesn’t require installation and only takes 5 minutes to play; then join me after the jump and check out my play through with a heart monitor.

Before I went to Southport’s Pleasureland I went to Blackpool Pleasure Beach (see earlier post). Unfortunately the sensor I was using was dislodged and the feature I was interested in, namely heart rate, was lost. While Blackpool ended up becoming a trial run for the next deployment I did manage to capture some fun breathing and g-force data.

Recently I’ve been looking at different ways of visualising physiological data, and have created a Poincare plot of a funfair ride at Southport PleasureLand I sampled last year. This form of visualisation plots current and successive heartbeats as x, y coordinates, so if a subject’s heartbeat was successively 70, 80 and 75 beats per minute (bpm) we would plot (70,80) and (80, 75) on an X-Y graph. In the instance below I’m plotting heartbeat activity as inter-beat interval which is the time between beats rather than the beats per minute. I’m particularly fond of Poincare plots as its easy to grasp a subject’s heart rate variability from casual inspection. At rest a subject’s heart rate variability should be high, and so individual beats should be spread out over the graph in somewhat of a noisily fashion. When stress is applied heart rate variability decreases and beats cluster.
