A Framework Proposal of UX Evaluation of the Contents Coherency on Multi-screens

As technical development has made it possible to access network at anywhere and anytime, various contents are being digitalized these days. Digitalized contents may be used on various devices without undergoing additional conversion. In the past, there were killer contents that were specialized for each device. But unlike the past, it is now possible to access to network anywhere and sync between devices such that users can enjoy the same content on a range of devices by pushing just a few buttons. Within this network environment, the multi-screen content UX has become a very important issue. As same content is displayed on various screens, a consistent UX must be used to minimize user confusion and maintain reliable experience. The purpose of this study is examine elements which enable users´ expectation of experience about the contents to be maintained equally, regardless of any devices, for example, screen size or operation method of the interface, and research them specifically. PC, Pad, Smart Phone, and TV are representative examples of multi screens. In addition, smart watches, watches functionally connected with smart phones, are spreading very rapidly these days. Size, operating environment and method of each screen are different, but we use the same contents (for example, YouTube) at each screen. Although many researchers or contents producers think they are creating contents considering the consistency of users´ experience, it is hard to find written documentation of the guidelines so far. Starting from the homogeneity of the surface design, users become to demand the consistency of the structure as they operate the screens. When all these things are in balance, users can experience the consistency of the contents used. In this study, guidelines which will enable users´ consistency to be kept steadily will be implemented, and then this will be applied to the existent contents for the evaluation. Outcome of the study can be utilized as the framework which will evaluate experience consistency of UX on multi screens.
