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). Such self-monitoring and self-sensing, which combines wearable sensors (EEG, ECG, video, etc.) and wearable computing, is also known as lifelogging. Other names for using self-tracking data to improve daily functioning are "self-tracking", "auto-analytics", "body hacking", "self-quantifying", "self-surveillance", and "Personal Informatics". In short, quantified self is self-knowledge through self-tracking with technology. Quantified self-advancement have allowed individuals to quantify biometrics that they never knew existed, as well as make data collection cheaper and more convenient. One can track insulin and cortisol levels, sequence DNA, and see what microbial cells inhabit his or her body. ==History== According to Riphagen et al., the history of the quantimetric self-tracking using wearable computers began in the 1970s:
Quantimetric self-sensing was proposed for the use of wearable computers to automatically sense and measure exercise and dietary intake in 2002:
(See also,.) The term "quantified self" appears to have been proposed in San Francisco, CA, by Wired Magazine editors Gary Wolf and Kevin Kelly in 2007 as "a collaboration of users and tool makers who share an interest in self knowledge through self-tracking." In 2010, Wolf spoke about the movement at TED, and in May 2011, the first international conference was held in Mountain View, California. There are conferences in America and Europe. Gary Wolf said “Almost everything we do generates data.” Wolf suggests that companies target advertising or recommend products use data from phones, tablets, computers, other technology, and credit cards. However, using the data they make can give people new ways to deal with medical problems, help sleep patterns, and improve diet. Today the global community has over a hundred groups in 34 countries around the world.〔http://quantified-self.meetup.com/〕 With the largest groups in San Francisco, New York, London, and Boston having over 1500 members each. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「quantified self」の詳細全文を読む スポンサード リンク
