PDR(Pedestrian Dead-Reckoning)
Estimates velocity vector, relative altitude, and action
type by measurements from a wearable sensor module.
 Wearing a sensor module on waist (2D SHS (Steps and Heading Systems) PDR)
 Easy to wear and maintain
 Easy to measure data for action recognition
 Relatively easily apply for handheld setting compared to shoe-mounted PDR
(3D-INS (Inertial Navigation System) PDR)

Standardization on PDR Benchmarking
• PDR related R&D is highly active worldwide: Necessity for sharing
common measures.
• Description of the performance should be unified in spec sheets and
scientific papers.
• Different measures from absolute positioning methods such as GNSS,
Wi-Fi, and BLE are required for PDR, which is a method of relative
positioning.
• PDR Benchmark Standardization Committee was established in 2014 as
a platform of the grassroots activity.
