In the context of the Municipal Council of Mytilene
project, a three-part system was implemented. A web tool
was implemented to allow tourists to create customized
mobile guides for their visit. A thick client application model
was chosen that does not require constant connection to the
Internet. The users ‘tag’ content items of interest through a
familiar web interface and select their device model to
download the application to a PC. Emphasis was given to
personalized services wherein the user’s explicit and implicit
profiles are used as input to the content recommendation
system; as such the use of personal web profile pages allow
users to upload comments and photos for other peers to view.
The use of sensor nodes as a means to detect user proximity
and allow users to connect and upload rating and
commenting data was seen as promising when a mobile
network connection was either unavailable or expensive to
use.
