Kurzfassung englisch:
The growing trend towards mobile phones with integrated GPS clearly suggests
that navigation and location-based services (LBS) will be key applications for
future mobile devices. New hardware features that are currently finding their way
into state-of-the-art phones - such as digital compasses and tilt sensors - promise
to drive the adoption of mobile geospatial services, and to change the way people
navigate, explore and interact with their physical environment: location-based
applications that exploit attitude information to realise orientation-aware
interaction have been discussed in research for several years. Yet, few actual
results on the achievable real-world performance of such systems exist
in literature. In this article, we report on a series of function trials carried
out with a prototype Geo-Wand - a portable system that allows users to access
geo-referenced information by physically pointing towards objects in the real
world. The application was realised with a mass market mobile phone connected
to a Bluetooth GPS and a custom-built orientation sensor module. We present
test results for multiple types of urban terrain and discuss the possibilities and
limitations of this next-generation mobile LBS technology.
