Mobile user experience (mUX) encompasses a broad sweep of technology, social and business research - from new interaction techniques for mobile devices, through location-based applications, to mobile services in entertainment, advertising, retail and gaming. This is a field where studies are rapidly executed and lean prototypes are quickly built and explored with users to evaluate the potential for new services. We want to create a journal that brings research to the community quickly - enabling new ideas to get traction allowing researchers to share first-view thinking with their peers - but with the academic rigour of a peer-reviewed journal.
