Finger gestures can be difficult to properly recognize. For example, the above-described problem may occur in the case of a wristwatch-type touch input device. Accordingly, there is a need to provide a new type of touch input technology capable of accepting efficient user input even when the touch sensing surface of the touch input device is narrow.
