Research Background and Research Issue
Existing research into
Peoples spatial ability Acquisition of spatial
knowledge Cognitive map Human-Environment
Interaction BUT The role of technology such
as mobile devices as a mediation between
environment and people has been hardly included
in these areas of research.
LBS Applications
There has been a general absence of research on
the extent to which applications are based on a
scientific understanding of the processes how
people retrieve and use the information.

Conclusions

• The research provides a theoretical model and
  test environment for studying many aspects of
  operational LBS
• Research on the information flow, transaction
  and process among the environment, information
  system and individuals
• Understanding how spatial knowledge is acquired
  and used for completing tasks in different
  geographical urban environments
• Understanding what are the relevant and
  meaningful information to people with the
  assistance of mobile devices and LBS applications
• Research on the desirable and effective ways for
  delivering information with regard to peoples
  spatial awareness, cognitive abilities?
