A mobile terminal like a Smart Phone or PDA with GPS or a Galileo receiver is necessary for use.  In addition, the mobile terminal needs to have Loccata software installed called Loccata Mobile Editor or L-ME.  If you have the use of this type of equipment you will be notified about available information as soon as you come close to a point of interest on your path.  The information given at each particular location depends on the settings.  As soon as you request information, you will receive detailed instructions for use.
