The internet of things is vastly emerging. The interface between the logical and physical worlds involves sensing and measurement as well as control, tracking everything that we (and machines) do on the internet or in physical space. For instance, with a little help of AI algorithm, software and electronics easily recognize faces.
They can also sense, measure and record temperature, store and manipulate sound, detect and manage machine performance; analyse physical forces. Internet is powerful enough to open and close switches, adjust settings, illuminate displays, set off alarms, respond to touch, authenticate people and their money.
The most important and ubiquitous connected device today is the mobile phone. It enables us to combine an understanding of physical context with knowledge of past behaviour, thereby amplifying our ability to predict intention and desire.
