Mobile, smart devices are already available in everyday life. Most
of them offer a rich feature set, including camera, GPS antenna, or
even WIFI modules. Navigation software utilizing GPS to acquire
location data became very popular on these mobile clients. However,
due to hardware restrictions GPS positioning cannot be used for
indoor scenarios. In contrast, this paper is focused on navigation
for indoor environments targeting on a low-cost solution, without
the requirement of additional hardware installations or markers
inside buildings. A server-based optical character recognition
service is used to map images containing unique text passages
acquired with a mobile client to additional meta data, e.g.
locations or orientation. We also show that augmented-reality
methods can be used to provide an intuitive presentation and
interaction system by overlying real- world images with additional
informa-tion like navigation symbols or internet hyperlinks.
