The Quantified Self is a movement to incorporate technology into data acquisition on aspects of a person's daily life in terms of inputs (e.g. food consumed, quality of surrounding air), states (e.g. mood, arousal, blood oxygen levels), and performance (mental and physical).[1]


The movement was started by Wired Magazine editors Gary Wolf[2] and Kevin Kelly[3] in 2007[4], as "a collaboration of users and tool makers who share[d] an interest in self knowledge through self-tracking". In 2010, Wolf spoke about the movement at TED[5], and in May 2011 the first international conference was held in Mountain View, California[6].


The primary methodology of self-quantification is data collection, followed by visualization, cross-referencing and the discovery of correlations.[7]
