Track3: Smartphone-based (off-site)

  • The goal:
  • To localize a pedestrian walking under realistic conditions:
  • in several multi-floor buildings
  • using a conventional smartphone and its available signals (WiFi,

inertial, magnetic, GPS, pressure, light,...)

  • Competitors:
  • Calibrate their algorithms with some logfiles data recordings

with inserted ground truth marks (~1000 marks)

  • Compete using new unreferenced logfile data
  • Award:
  • TECNALIA awards a €1.500 cash prize to the winner

SLIDE 3

Challenges (1/2)

  • Multiple buildings:
  • Multiple sources of information:
  • WiFi RSS, Inertial data (Accelerometer and

Gyroscope), Magnetic, GPS, AHRS, Pressure, Temperature, Humidity, Sound intensity and Light intensity

  • Continuous motion & recording:
  • Different sampling time (WiFi every~6s),
  • Acc (~50Hz), different for others

CAR (ID 10) 1 floor UAH (ID 20) 4 floors UJIB (ID 30) 6 floors UJITI (ID 40) 4 floors

Challenges (2/2)

  • Realistic walking style:
  • Mainly forward, also lateral/backwards, turns 90º&

180º, elevators/stairs, giving way to other people.

  • Limited info of buildings:
  • Multiple WiFi AP, but position of each AP is unknown.
  • Geo-referenced floor-map bitmaps (no vector format)
