Humans interact with electronic devices consisting of different and complex interfaces in almost every second of the lives. This sudden constant interaction with electronic interfaces has seen a sudden surge in usability experts and technology developers to focus and invest more in their user interfaces. The easier yet comprehensive interface of a system, the more chances it will have to observe a decent sale and profits. Companies are considering user experience as the utmost quality factor as it's vital to achieve maximum profits in a competitive world like today. Numerous UEMs have been developed over the years to ensure user satisfaction.
