In this paper, we propose an image and tactile presentation system for quickly moving objects, high-speed dynamic information environment, and a calibration method between a camera and Airborne Ultrasound Tactile Display(AUTD), which can present tactile sensation noncontactly as focused ultrasound. We realize one example of high-speed dynamic information environment that even if an object is moving, we can use the object as a tool for human interfaces without delay by combining a high-speed gaze controller by rotational mirrors. An accuracy of position, however, is not sufficient against difference threshold between images and tactile sensation because of mainly error of position between AUTD and camera. We calibrate the AUTD-camera system by visualizing the invisible focal position using Frustrated Total Internal Reflection(FTIR). Experimental results show that estimation accuracy is better than the threshold.
