Abstract
  • Networking technology has become applicable in domains beyond the conventional computer. One such domain currently receiving a significant amount of research attention is networking arbitrary devices such as TVs, refrigerators, and sensors. In this dissertation, we focus on the following question: how does an infrastructure deploy a user-interface for a single device or a composition of several ones? We identify and evaluate several deployment approaches. The evaluation shows the approach of automatically generating device user-interfaces 'on the fly' as particularly promising since it offers low programming/maintenance costs and high reliability. The approach, however, has the important limitation of taking a long time to create a user-interface. It is our thesis that it is possible to overcome this limitation and build graphical and speech user-interface generators with deployment times that are as low as the inherently fastest approach of locally loading predefined code. Our approach is based on user-interface retargeting and history-based generation. User-interface retargeting involves dynamically mapping a previously generated user-interface of one device to another (target) device that can share the user-interface. History-based generation predicts and presents just the content a user needs in a device's user-interface based on the user's past behavior. By filtering out unneeded content from a screen, it our thesis that history-based generation can also be used to address the issue of limited screen space on mobile computers. The above ideas apply to both single and multiple device user-interfaces. The multidevice case also raises the additional issue of how devices are composed. Current infrastructures for composing devices are unsuccessful in simultaneously providing high level and flexible support of all existing composition semantics. It is our thesis that it is possible to build an infrastructure that: (1) includes the semantics of existing high-level infrastructures and (2) provides higher-level support than all other infrastructures that can support all of these semantics. Such an infrastructure requires a composition framework that is both data and operation oriented. Our approach is based on the idea of pattern-based composition, which uses programming patterns to extract data and operation information from device objects. This idea is used to implement several abstract algorithms covering the specific semantics of existing systems.
