N2 - We propose a novel interaction technique, called Copernican-Touch, that increases touch-input vocabulary by distinguishing between conventional touch (i.e., moving a finger towards a touch surface) and a touch input involving moving a touch surface towards a finger. Using a device motion and a touch input as delimiters, particular short-cut command can be executed immediately after a touch input. Therefore, it does not require a long waiting time before executing a command such as long press or force touch. We conducted an experiment to verify the feasibility of our technique on the smartphones and smartwatches. The result of machine learning shows recognition accuracy of 87% for smartphones and 88% for smartwatches. In accordance with interview comments, such as that it was a little difficult for users to accurately touch the intended position, we discuss potential applications of our technique.
