Jewellery (or American jewelry) is a term that commonly refers to forms of personal adornment, worn on the body. The earliest known jewellery dates as far back as 100 thousand years [Vanhaereny, 2006] and has been manifesting itself in analogous forms and much the same purpose throughout its history. Although there are basic categories of jewellery, such as brooches, rings, necklaces, bracelets and earrings, the forms that these take are of incalculable variety. These varieties often resulted from cultural idiosyncrasies, individual expressions, fashion and not least from the available technology.
Computational jewelry (colloquially referred to as smart jewelry, or in earlier research digital jewelry) is a term, coined by Molina-Markham et al in their poster “Poster: Enabling Computational Jewelry for mHealth Applications “ [Molina-Markham et al., 2014]. It refers to the adornment artifacts that function both as jewellery and as a computational device. Until just a few years ago most of the computational jewellery consisted of hypothetical prototypes and artistic one-offs separately creased created by researches and jewelers. Multidisciplinary collaboration in conjunction with the release of Low Energy Bluetooth (BLE) in 2010 along with and general miniaturization of components brought computational jewellery into the domain of tangible products, with fourteen projects funded Kickstarter and IndiGoGo projects in this year alone.
