“…Schmitz et al [15] have proposed a design system for 3D objects with capacitive touch sensors, and based on this, a tangible interface with conductive parts using a 3D printer has been proposed [16,17]. Kato et al [16] have proposed a tangible interface that generates touch input on a touch panel when the user touches a grid with multiple conductive points by printing it with a fused deposition modeling (FDM)-based 3D printer. This allows the user to control the touch input at any position on the printed interface surface.…”

With the spread of devices equipped with touch panels, such as smartphones, tablets, and laptops, the opportunity for users to perform touch interaction has increased. In this paper, we constructed a device that generates multi-touch interactions to realize high-speed, continuous, or hands-free touch input on a touch panel. The proposed device consists of an electrode sheet printed with multiple electrodes using conductive ink and a voltage control board, and generates eight multi-touch interactions: tap, double-tap, long-press, press-and-tap, swipe, pinch-in, pinch-out, and rotation, by changing the capacitance of the touch panel in time and space. In preliminary experiments, we investigated the appropriate electrode size and spacing for generating multi-touch interactions, and then implemented the device. From the evaluation experiments, it was confirmed that the proposed device can generate multi-touch interactions with high accuracy. As a result, tap, press-and-tap, swipe, pinch-in, pinch-out, and rotation can be generated with a success rate of 100%. It was confirmed that all the multi-touch interactions evaluated by the proposed device could be generated with high accuracy and acceptable speed.

“…Many works apply variations of capacitance tags [34]. By embedding conductive material or by adding electronics to the tangible object, the capacitive touch sensor can detect presence and location of tangible objects [57,52,51], combinations of multiple objects [7], or forward touch on the object onto the touchscreen [7,19,20]. Other approaches utilize magnetic hall sensor grids to identify objects [25] and detect their posture above a screen [24].…”

“…Other approaches print interactive objects by means of conductive spray [17] or conductive plastic [23,40,41,6,20]. 3D printing is also explored for fine-grained design of deformation behavior of non-interactive flexible objects [32,43,31,4] or to fabricate soft interactive objects [15].…”

“…It has been shown that the capacitive touch sensor itself can be used to identify the location and orientation of a tangible object [34,21,7,52]. Moreover touch input on an object's surface [7,40,20] or the configuration of mechanical controls with moving parts [7] can be detected. These approaches work with passive objects, which do not contain any electronics and therefore can be produced at low cost.…”
