“…Our research on the other hand, utilizes screen overlays to generate the friction coefficient for creating directional forces. Expanding on the research of Kaye [14] and Reznik et al [2], our previous work [15,16,17] utilizes saw tooth vibration signals to create onscreen directional forces through stick-slip motion.…”

“…Using the saw tooth signal waves specified by Kayes [14], we were able to move tangible objects over the touchscreen surface without any mechanical linkages. Using this setup we have developed a number of stylus based applications [15,17] from handwriting learning to 2D gaming interaction on a simple touchscreen device. However, if we look at the actuation mechanisms employed in the SKDS system, we see that although conventional vibrotactile feedback actuators can be used in the SKDS, they are perhaps not the most efficient method in creating the stick-slip motion necessary to move tangible object of the screen.…”

“…On the contrary smart systems, such as SKDS, require calibrated actuation parameters, such as force, displacement, accuracy and efficiency along with the consistency to be able to reproduce the physical parameters needed, during every actuation cycle. Our previous research [16,17] showed that ideal actuators for SKDS systems need to ensure displacement values of about 1.5mm or greater, under an average load of about 200g, within a consistent period of 3ms.

In line with our previous work, this research focuses on enhancing touchscreen based interaction through stick-slip phenomena. By balancing inertial and frictional forces on a transparent screen overlay, we can control the resulting directional forces specific to multiple objects on a touchscreen surface. Using "stick-slip" phenomenon, we can associate tangible objects in relation to their virtual environment and adjust their behavior in real time without any stiff mechanical linkages. Our previous research shows the possible advantages of such a system (Stick-Slip Kinesthetic Display Surface) for a wide range of applications, such as continuous supervised input as well as novel applications with cross-environment interaction, where real-world physical objects can interact with their virtual counterparts and vice versa. However, to ensure that the directional forces are sufficient for these and other types of applications to serve as the system output, the mechanical actuation mechanism needs to be specifically designed for the particular novel use case. This research utilizes an electromagnetic setup to develop custom designed linear actuator which can increase the efficiency of the stick-slip based system. Our testing shows that the custom actuator is stable and more efficient at generating directional forces in the smart kinesthetic display surfaces (SKDS) as compared to actuators designed for conventional vibrotactile feedback.
