Description

This paper proposes a method for reducing fatigue during handling medium-weight objects and augmenting our endurance by affecting our weight perception with augmented reality technology. Psychological studies revealed our weight perception during handling objects is affected by their visual property. We hypothesized that this illusionary effect in weight perception can be applied to reduce fatigue during handling medium-weight objects without mechatronics-based physical assistance which requires complex structures and various costs. We propose an augmented reality system which changes the brightness value of an object in order to reduce weariness during handling it. We conducted two fundamental experiments to investigate the effectiveness of the proposed system. Subjective and quantitative evaluation suggested that our system reduces fatigue during the handling task and improves energy efficiency by cutting away excess energy.
