In this study, we have investigated the enhancement phenomenon of haptic perception caused by simultaneous tactile stimuli to both hands. In our previous studies, we have examined the contact conditions and how to move hand. This paper investigates spatial-temporal consistency of the stimuli in both hands. We gave spatial changes or temporal changes in tactile stimulation, and compared changes of the intensity of perceived stimulus. The result shows the influence of temporal changes is small, but the influence of spatial changes is large and spatial consistency of the stimuli is important for the enhancement effect.
