Internet of Things (IoT) isn't a new concept but it's only just started to take shape in the consumer market. One of the more recent trends, smartwatches, are available from brands such as Apple, Samsung, Fitbit and Pebble but seem to only scratch the surface of health and fitness applications. This book takes a novel approach and explores the less obvious applications of a smartwatch. You will get to see how it's possible to take an everyday task such as handwashing and go all the way from inception, design and development through to usability trials to see if it's really possible to shape a person's hygiene habits in a meaningful way.
