Abstract EN
In this paper, we propose a density estimation system of user density at the closed space using high frequencies of speaker and microphone of smart device.
High frequencies are sent to the closed space by the server speaker of the density estimation system, and smart devices located at the space detect the high frequencies via the microphone of each device.
The smart devices detecting the high frequencies send data to the server system, and the system calculates data from the smart devices.
To evaluate performance of the proposed system, we did some experiments with the density estimation system and 20 smart devices.
According to the test results, the proposed system showed 96.5% accuracy, and we confirm that the system is very useful for density estimation.
Therefore, this system can precisely estimate user density at the closed space, and it could be useful technology for the density estimation of space users and measurement of space using state at indoor space.
