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.

Over at PhysiologicalComputing.net me and Steve announced our upcoming book Advances in Physiological Computing: an edited collection of the latest research in the field. The book will be released in April by Springer. You can check out the book webpage at Springer here and our book webpage here.
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.
