With the 4G mobile technology, LG U+ established a new business model, inter-network mirroring game service, that allows PC and mobile game users to play against each other. However, due to an unsolicited input command design for touch-sensitive UIs, it is hard to adjust competitive levels between them. The traditional Keystroke-Level Model (KLM) was not applicable to predict the task performance in the touch-sensitive user interface. This case study thus proposed Fingerstroke Level Model (FLM), and analyzed the inter-network mirroring game - 'Freestyle II"' with FLM. The empirical study confirmed the effectiveness and efficiency of FLM, and suggested how HCI methods can improve the design of mobile gaming user interface.
