Down-scaling of a tourist assistance system to fulfil the needs of economical poor regions and providers of tourist offers

Derived from a complex tourist assistance system for users with special needs (e.g. disabled users with physical impairments) a down-scaled system was successful tested. It consists of a handheld device like the whole system but disclaims to a permanent online server access. The reducing of components was determined by a user-centred design process with an intense requirement analysis.
