Abstract: A proactive user interface, installed in (or otherwise control and/or be associated with) any type of computational device. The proactive user interface actively makes suggestions to the user, based upon prior experience with a particular user and/or various preprogrammed patterns from which the computational device could select, depending upon user behavior. These suggestions can be made by altering the appearance of at least a portion of the display, for example by changing a menu or a portion thereof; providing different menus for display; and/or altering touch screen functionality. The suggestions can also be made audibly.

Abstract: A computing application for a mobile information device is generated from An extensible markup language, MIDML, in which different types of tags correspond to different application functions. A command line compiler parses the MIDML specification, reading the tags in specialized readers, which are then accessed by generators of specialized objects for an object model using different generators for each type. A predefined set of tags is extendible by the application developer. The generation process results in Java source code, which is then compiled into a MIDlet and packaged into a JAR file and a JAD file.

Abstract: An infrastructure is provided for creating applications for mobile information devices, using a tag-based markup language. Developers can use the markup language to define applications and content based on easily manipulated textual tags, rather than having to write specific source code. A compiler, processes the tags in several phases. In one phase, a hierarchical object model of the application is populated with objects. Then, in another phase, a generator traverses the object model hierarchy in a top-down manner, producing source code files corresponding to objects in the object model. The code files may include various elements, for example screens, forms, and servlets. For each element required to be generated, an appropriately configured generator class is invoked. The output code can be Java source code.

Abstract: An infrastructure is provided for creating MIDlet applications on demand for mobile information devices, using a tag-based markup language. A servlet running on a web server, acknowledges the request of the remote mobile information device for an application. If the requested MIDlet is found in the server's cache, it is downloaded to the requester. Otherwise, the servlet identifies the characteristics of the mobile information device, and identifies resources that are required to produce an updated MIDlet in order to satisfy the request. A compiler is then invoked to generate the requested MIDlet, which is then packaged and downloaded over-the-air to the requestor.

Abstract: An infrastructure is provided for creating applications for mobile information devices, using a tag-based markup language, MIDML. Applications are defined based on easily manipulated textual tags, without need for writing specific code. The tags are processed to ultimately generate source code files. Initially, the input is parsed. Next, a hierarchical object model of the application is populated with objects. Separate readers read and parse the different tags and accompanying elements. The readers are registered in a descriptor object factory, to be instantiated as required in processing extended MIDML files. The object model enables the capabilities of the system to be easily extended, simply by adding new tags, and readers to the existing factory set. The resulting object model is accessible to a generator that produces the actual output.

Abstract: A computing application for a mobile information device is generated from An extensible markup language, MIDML, in which different types of tags correspond to different application functions. An library infrastructure parses the MIDML specification, reading the tags in specialized readers, and generating specialized objects for an object model using different generators for each type. A predefined set of tags is extendible by the application developer. The generation process results in Java source code, which is then compiled and packaged into a JAR file and a JAD file. An applications layer includes a servlet, which processes user requests for the computing application, and causes an appropriate version to be downloaded over a data network.
