This paper proposes an intuitive input interface that can handle various operations based on finger image recognition. It receives continuous analog input by detecting a knuckle of the user's clenched fist. In contrast to the conventional wireless mouse, whose sensitivity cannot be changed dynamically, the proposed method brings not only stable positioning but also quick clicking with a small finger gesture. In order to evaluate operability, we conducted a user experiment: a time trial for target selection. The subjects completed the task with the proposed controller in 44% less time than with a conventional wireless mouse. We confirmed that the proposed method can reliably follow finger gestures.
