In recent years, tele-operation of construction machineries has been intensely investigated in order to improve the working environment for their operators in the construction field. Vision is an important factor for the understanding of the environment in the remote control. However, the relationship between the operability and the resolution of presented image has not revealed. In this study, we evaluated the influence of the resolution of presented images for sense of presence and perspective among three resolution levels (SD, HD, 4K). The experimental results suggest the trend that both sense of presence and perspective improve as the resolution of presented images becomes higher.
