“…Voelker et al [21] created a multi-touch interface that does not require contact with a battery or human body by electrostatically coupling a transmitting electrode in a touch panel to a receiving electrode at another position via a conductive bridge as an interface for generating touch input. Takashina et al [22] have proposed a method to operate the touch panel without using fingers to automate the operation of the touch panel. They propose two methods to achieve the quasi-touch: the resistance control method, in which a semiconductor switch is contacted to cause a direct charge movement on the surface, and the capacitance sensor control method, in which an alternating-current (AC) signal is given from the outside to deceive the capacitive sensor.…”

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.
