Professor Deborah Lupton of the University of Sydney has a great many things to say about QS concepts. A blog worth visiting here. She writes:

"These technologies include not only digital cameras, smartphones and tablet computers, but also wearable wristbands, headbands or patches with digital technologies embedded in their fabric able to measure bodily functions or movement and upload data wirelessly. Tiny sensors can also be incorporated into everyday items such as toothbrushes, pyjamas or watering cans to measure such activities. Blood pressure cuffs and body weight scales can be purchased that connect wirelessly to apps. Global positioning devices and accelerometers in mobile devices provide spatial location and quantify movement. Apps that regularly ask users to document their mood can monitor affective states. There seems hardly a limit to the ways in which one’s daily activities can be monitored, measured and quantified. Some committed self-trackers even regularly send stool and blood samples for analysis and use commercially available genetic tests as part of their efforts to construct a detailed map of their bodily functions and wellbeing."

The latter special issue in JLBS that MG and I guest edited is especially rich with observational perspectives of tracking, in addition to human activity monitoring capabilities presented by Deutsche Telekom.
