Research On Approach To The Pattern-based Dialog Control Description For Mobile User Interfaces

Intelligent mobile terminal is gradually becoming trend in dominance with the development of technology. It has become a trend of designing and developing Apps for the mobile platform, at the same time,it also come up the new challenge about how to implement mobile user interface with the dialog control component. Modern UI development has been divided into two categories-the presentation of interface and the dialog with interface.As we all know,it is extremely difficult to develop the complicated UI,which often requires the appropriate tools to support. The traditional UI development method based on the model has supported presentation component. However, it is still lack of the related method to develop the dialog component.Developers have to hand-coding in the low level, which adds to time and money cost. So how to ensure the usability of the interface while quickly and efficiently to implement dialog control become a problem to be solved.Traditionally, human-computer dialog represents the information interaction process set out by users according to specific task, system and software’s. As for the aspect of scenario dialog control, nevertheless, apart from information communication between interface and outside users, it is also essential to define logical relationships and communicating forms within interface. However, due to the small granularity of interface components and complicity of interface semantic, relationships between these components is difficult to describe. As a result, it becomes impossible to automate interface dialog control.Compared to interface components, UI pattern is an interface structure with bigger granularity. By introducing UI pattern, narrowing interface semantic scope to a specific application scenario and pre-defining dialog control semantics, UI pattern offers a solution to automation of dialog control model in interface.This study come up with a UI pattern based dialog control model (PML-DM). The model meets the demands for dynamic dialog, improve developing efficiency so as cut down developing cost. It also guarantee the usability on basis of UI semantic information.The research is carried out on the two following aspects. First, it offers definition and description over dialog semantic of UI. By structuring dialog control model, it offers the communication norm between elements of UI mode. Second, the study combines dialog control model with current-existing static pattern library, and realized UI pattern with dialog control on mobile platform, which improves the dialog developing efficiency on basis of UI usability.
