A Sequence-Action Recognition Applying State Machine for User Interface

This paper presents a novel user interface that recognizes a user´s sequence-action to supplement the lacking user interface of mobile devices. To recognize user´s various actions (user´s gestures and postures) in order of precedence, we used a state machine algorithm. We created mobile games such as fishing and bowling on mobile phones by using this algorithm. The demonstrations show the usability of this state machine for sequence-action recognition.
