Microsoft Indoor Localization Competition• 36 submissions from 32 teams• 21 teams with 22 systems eventually participated• Academia, Industry, Startups
• Submissions were classified into two categories• Infrastructure-free (9 teams)
• No hardware deployment• WiFi and sensors (accelerometer, gyro, etc.)
• Infrastructure-based (13 teams)• Custom hardware deployment (magnetic, custom RF, light-based, etc.)
Microsoft Indoor Localization Competition• 2-day event• Day 1: Sunday
• Teams were given 7 hours to setup and calibrate their systems
• Day 2: Monday• Each team was asked to provide the
coordinates of 20 test points • Test points’ coordinates were manually
measured using laser range finders
• Evaluation Metric• Average localization error across the 20
test points
