Proceedings of the SIGIR 2008 Workshop on Mobile Information Retrieval 24 July 2008 , Singapore

This is a survey how cell-phones are interacting with a real world with I/O devices in information retrieval. Many cell-phones are now being equipped with many I/O devices including GPS, microphones, CCD/CMOS cameras, and motion-sensors. Thus content delivery, interaction with contents, and e-commerce are going to be associated with real environments which will bring us context-aware(real-world aware) capability. Here we see the clear distinction between cell-phones and mobile laptop PCs in that context. Interaction is the key when considering mobile information retrieval. Having 3G broadband and low-latency technologies, “always-on” mobile infrastructure has brought an on-demand and real-time information retrieval capability in conjunction with a popular communication culture, which we call “the third generation of cell-phone culture”, which was never seen before. That is In next two decades, billions of cell-phones are now being connected to server cloud. We may have a different level of real-word aware computing which has not emerged yet.
