SNOW - A multimodal approach for mobile maintenance applications

Today's maintenance operations highly depend on access to information and team expertise from various locations. To describe and to transmit such information, different hurdles have to be taken, like providing device independent content descriptions, capability dependent adaptations, integration of various reliable I/O modalities or cumbersome environment restrictions. This paper describes an infrastructure for deploying aircraft maintenance procedures to mobile workers, including a multimodal mark-up language, a semantic framework for rich and lightweight clients, and an adaptation methodology. The presented information demonstrates an approach for integrating mobile information systems into aircraft maintenance and could be used for adapting information technology (IT) to other related mobile application domains.
