What are Wearables and Quantified Self?

Wearables and Quantified Self refers wearable technology that’s worn on the human body – often as an accessory or within clothing – used to record vital signs or other ambient information that’s fed back to the wearer.

Examples of Wearables includes smartwatches, medical alert monitors, fitness trackers and even smart tattoos.

Whilst Wearables is a broader term of electronic devices worn on a user’s body, Quantified Self (sometimes shortened to QS) refers to the process the self-tracking, measurement, and quantification of all aspects of daily life. Quantified Self also encompasses the ecosystem of users and makers of tracking tools and the further progress of self-knowledge through data.
