6.8.1.1.4: Provide Personal Portable Device Wayfinding Guidance

This process shall be responsible for providing a user interface for the traveler through which personalized wayfinding guidance can be delivered. The process shall enable the traveler to input data to request a suitable wayfinding route. This process shall be capable of supporting two types of route guidance: dynamic (infrastructure based guidance is provided to the personal portable device), and autonomous (the personal portable device uses only locally available data- there is no information provided by the infrastructure). The process shall also act as the interface for output of on-line guidance to the traveler. The process shall not provide on-line guidance until the route has been accepted by the traveler. The process shall support inputs from the traveler in either manual or audio form, and shall provide outputs in audible or visual forms. The process shall produce outputs that support a wide array of personal travelers preferences or requirements based on their physical limitations.
