Research on Configuration Arrangement of Spatial Interface in Mobile Phone Augmented Reality Environment.

Recently, due to the release of ARKit and ARCore, the mobile phone can achieve stable motion track via COM (concurrent odometry and mapping). By this way, mobile phones can display the interface in the real space like the multimodal interface in VR (virtual reality) glass, users can browse and interact with interface not only by touching screen but also by motion modal (moving and rotating mobile phone). This paper studied the optimal arrangement of spatial interface and the influence of various layout parameters on browsing efficiency. Through the test platform program, users can adjust the layout parameters (shape, distance, and size) of the spatial interface, and do some browsing tasks in each layout type. The result of interview feedback data analysis showed that the main factors affected by layout parameter on the browsing experience are screen size, movement rate and mapping deformation. And calculated their alternative relationship with layout parameters. Finally, through the recorded data of browsing speed and satisfaction coming from test platform, it figured out the best value and critical point for each layout parameters.
