DESCRIPTION:Research: Pedestrian Localisation for Indoor Environments\, Ol
 iver Woodman\n\nLocation information is an important source of context for
  ubiquitous computing systems. This paper looks at how a foot-mounted iner
 tial unit\, a detailed building model\, and a particle filter can be combi
 ned to provide absolute positioning\, despite the presence of drift in the
  inertial unit and without knowledge of the userís initial location. We s
 how how to handle multiple floors and stairways\, how to handle symmetry i
 n the environment\, and how to initialise the localisation algorithm using
  WiFi signal strength to reduce initial complexity. We evaluate the entire
  system experimentally\, using an independent tracking system for ground t
 ruth. Our results show that we can track a user throughout a 8725 square m
 etre building spanning three floors to within 0.5m 75% of the time\, and t
 o within 0.73m 95% of the time.\n\nSkills: Atmel Programming\, Brian Jones
