This video is part of an initiative by SDU's Biomedical Engineering Centre to improve the accessibility of scientific papers with human-narrated article readings. The text is read out in full in the same manner as a non-fiction unabridged audiobook, with the article displayed page-by-page on-screen for those wishing to see figures, equations and references.
This paper presents a method for the precise synchronization of inertial measurement unit (IMU) data with a computer system clock, using a motor-controlled turntable, to allow more accurate labelling of motion data. Using the case of human reaction time measurement, where motion is recorded as a response to a computer-controlled visual signal, this methodology proved capable of compensating for IMU clock drift and latency between systems, providing a robust and simple solution for applications in a wide range of IMU-sensor-equipped systems.
