This chapter investigates the research projects and prototypes related to currently available mobile applications used in wayfinding and navigation. The advancement in small-screen devices, mobile computing and modelling counterpart, location awareness techniques, and wireless technologies have improved screen resolutions and provided technical solutions for delivering textual, 2D, and 3D information to a mobile device. After investigating small-screen representations and the related navigation content and mobile interface design from the previous cases, two suggestions are presented in this chapter in order to enhance the design for future mobile wayfinding systems: 1) pseudo-3D representations and 2) personalised and on-demand services.
