Study On Adaptive-Module-Based UI Models For Multi-Platforms

As the expansion rate of mobile platforms is becoming greater and their capabilities have considerably improved, there is now a need that the applications for mobile platforms have this characteristic: it can migrate from one machine to another, taking their user interface and application contexts with them, and continue from where they left off. Such applications are not tied to one user or one machine, and can roam freely over the network, rendering service to a community of users, gathering human input and interacting with people. The ability to migrate executing programs has applicability to mobile computing as well. Users can have their applications travel with them, as they move from one computing environment to another.A platform is generally defined as a specific combination of hardware and operating system. Sometimes, the capabilities of each platform are very different: the devices differ in screen size, resolution or color number, capacity of computation, interaction mode, languages, and so on. How to solve the difficulties brought by these differences, and pay attention to the main tasks, is a great challenge. At the same time, UI designers expected to be able to reuse their knowledge of a given version of the system when designing the same item for another platform.We propose an approach called a presentation model bases on adaptive module as method to build user interfaces for multiplatform systems. The essence of this approach consists in composing several functions of abstraction, reflection, translation. By configure the data object, abstract interface, event route table, we gained the mapping of data, event, and interface. Then with the UI generator, we get the final UI that meet our requirements.We also propose an evaluation method of resource satisfaction in interface migration. This paper adds a data structure to the User Interface (this data structure is grouped by certain rules), and establishes a corresponding algorithm which regards this structure as the parameter. The algorithm can judge the feasibility of interface migrating through the calculation of the target platform's resources, and provides related information for the UI adjustment before UI migration.
