Location and Orientation-Aware Presentation of Information on Mobile Devices

Today´s mobile computing devices, such as PDAs and smart mobile phones, increasingly offer functionalities beyond calendar manangement and address books. They serve as mobile internet terminals and allow email and web browsing. The usefulness of such devices can be substantially enhanced by making them location aware. We discuss different approaches to location aware services and argue that most of the intelligence behind such services should be located in the infrastructure rather than the actual device. We present the IRREAL project in which a location sensitive information service was realized by the help of Palm Handheld Organizers and infrared data transmission. After describing several functional details of the system and how they improve its performance, we present some suggestions, how the concepts developed in IRREAL can be transferred onto new emerging technologies.
