Lab-Forming Fields and Field-Forming Labs


Published on

present the concept of Lab-Forming Fields (LFF) and Field-Forming Labs (FFL). LFF is to transform real service fields into lab-like places for bringing research methodologies in laboratories to real fields with IoT. FFL is to transform laboratories into real-field-like places for getting subjects’ behavior and experimental results closer and closer to the ones which are supposed to be obtained in the real service fields with VR. Next, I introduce indoor positioning technologies such as PDR (Pedestrian Dead Reckoning) as a key technology for human behavior sensing. Then I conclude this talk by briefly reporting on case studies of service kaizen in a restaurant and a warehouse respectively.

  22. 22. 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. 22

The read area indicates subjects spent longer time than other area. Because position data of the real store situation is recorded by hand, we only have the discrete position and timestamp data. Therefore, we could not compare both of them strictly, but we found out we could get the similar results. Comparison of heat-map visualization of stay Virtual store in SFSReal store
