A situated computing framework for mobile and ubiquitous multimedia access using small screen and composite devices

摘要

In recent years, small screen devices, such as cellular phones or Personal Digital Assistants (PDAs), enjoy phenomenal popularity. PDAs can be used to complement traditional computing systems to access personal multimedia information beyond the usage as digital organizers. However, due to the physical limitations accessing rich multimedia contents and diverse services using a single PDA is more difficult. Hence, the Situated Computing Framework (SCF) research project at Siemens Corporate Research (SCR) aims to develop a ubiquitous computing infrastructure that facilitates nomadic users to access rich multimedia contents using small screen devices. This paper describes a new distributed computing concept, the Small Screen/Composite Device (SS/CD) framework, which offers mobile users new classes of ubiquitous and mobile multimedia services without to limit the diversity and the richness of the provided services.
