Abstract

In this study, we developed a real-time measurement and feedback system for floor cleaning using a sheet-type mop. In this system, the full-body motion of the cleaner and the motion of the mop are measured. The swept area by the mop is estimated from the motion of the mop. During the cleaning, the vibro-tactile, and visual feedback is provided to the cleaner for improving the efficiency of the cleaning. In particular, the vibro-tactile stimulation according to the number of sweeping on the current area (SF: swept-count feedback), the visual information just by showing the swept area to the cleaner through a display (VF: visual feedback), and the vibro-tactile feedback according to the flexion angle of the torso (MF: motion feedback) are implemented. The purpose of this study is to analyze the effect of feedback on the efficiency of the cleaning and motion of both full-body and floor mop. The floor cleaning experiment is conducted with eight males and eight females. For each participant, the cleaning tasks with the three feedback (SF, VF, or MF) are measured. Also, two trials without the feedback are measured before (NFF) and after (NFL) the three trials with feedback. Our results indicated the potential of real-time feedback for improving the efficiency of the cleaning and body posture.
