Low latency breathing frequency detection and monitoring on a personal computer.

We demonstrate a low latency respiratory/breathing frequency detection system that is fast (<5 ms), easy to operate, requires no batteries or external power supply and operates fully via computer-standard USB connection. Exercises in controlling ones breathing frequency, usually referred to as paced-breathing exercises, have shown positive effects in treating pulmonary diseases, cardiovascular diseases and stress/anxiety-related disorders. We developed a breathing frequency detection system which uses two pairs of microphones to detect exhalation activity, eliminate noise from the environment and stream the recording data via USB connection to a personal computer.

Why do we follow sporting events?

The aim of the study was to investigate the motives for following sporting events and their dependence upon gender and age of spectators. The study was based on a survey of 1727 adult Slovenes. According to the results the most important motives could be classified in the category of Dionysian values.
