Old ways of measuring electrical signals, like the EEG shown above were the purview of mega-geeks and researchers. The new generation of self-trackers can fit in a pocket, onto a headband or in your smart phone.

With smart phones and tiny self-trackers like FitBit and DirectLife you can measure every movement and moment consumed – from time spent in REM sleep and calories ingested to mundane tasks like waiting in line and washing dishes – and learn how this knowledge affects your moods. Do we really need this much information about ourselves? How useful is it? And are the odd habits of self-tracking ultra-geeks the new normal? Wired magazine’s Gary Wolf tells us why numerical navel-gazing may soon displace linguistic forms of self-exploration.
