We proposes a novel method that renders haptic perceptions only using a touch screen based on visuo-haptic interaction. Our proposed method evokes a feeling of resistive force by making a discrepancy between the movement of the finger swiping the screen and the background image which moves according to the finger movement. First experiment shows that the proposed method can evoke perception of resistance according to the constant ratio between the displacement of the finger and background image. That is to say, the user perceives strong resistance to move when the background image moves slower than the finger. Moreover, same experiment also suggested that the evoked haptic perception becomes stronger when the method is applied to frequently repeated movements. Second Experiment shows that visibility of the finger on touch screen is important factor for proposed method.
