User Interface Consistency Experience in Composite Cross-device Interaction
Authors: Jiahe Zhang, Yuan Xiang
Abstract: The complexity of cross-device interaction brings challenges to the design of user experience. Related research has investigated the elements of cross-device scenarios and the design principles of different scenarios. To explore the consistency of user experience for a single user in multiple temporal cross-device scenarios, this study first defined the concept of composite cross-device scenarios that include cross-device interactions with asynchronous and synchronous operations. Then, based on the principle of cross-device consistency, three interface distribution strategies under three composite cross-device scenarios, mirroring, split view, and split interaction, were constructed. Finally, through experiments, the user experience of the above three interface distribution strategies is tested under the two tasks of "operation-oriented" and "observation-oriented". Experimental results show that there are differences in user preferences for different interface distribution strategies in two different tasks. In each group, the mirrored pattern received the highest score. Through semi-structured interviews, it is found that users pay the lowest learning cost for performing cross-device operations in mirror mode. Separation of view and separation of interaction score relatively high in operation-oriented and observation-oriented task scenarios, respectively. This difference indicates that the cross-device interface distribution method needs to meet the interaction requirements of the task.
