Apparent tactile motion (ATM) has been shown to occur across many contiguous parts of the body, such as fingers, forearms and the back. More recently, the illusion has also been elicited on non-contiguous part of the body, such as from one hand to the other when interconnected or not interconnected by an object in between the hands. Here we explore the reproducibility of the intermanual tactile illusion of movement between two free hands by employing mid-air tactile stimulation. We investigate the optimal parameters to generate a continuous and smooth motion using two arrays of ultrasound speakers, and two stimulation techniques (i.e. static vs. dynamic focal point). In the first experiment, we investigate the occurrence of the illusion when using a static focal point, and we define a perceptive model. In the second experiment, we examine the illusion using a dynamic focal point, defining a second perceptive model. Finally, we discuss the differences between the two techniques.
