本研究關心遊戲玩家面對同一款遊戲在不同遊戲平台採用不同遊戲介面的遊戲表現。32 位受測者根據觸控螢幕、鍵盤和手把 3 種遊戲介面的年度累計投入時間（簡稱介面投入時間）來進行分群，共同參與由被視為自變數的 4 種遊戲介面搭配被視為實驗任務的 6 款平台遊戲的實驗任務，其遊戲得分被視為依變數。結果顯示：(a) 整體來看，介面投入時間的多寡顯著影響遊戲表現；(b) 單一介面投入時間越多，則受測者使用該介面之遊戲表現越好；(c) 單一介面投入時間越多，受測者不一定越容易適應其他三種遊戲介面，但鍵盤除外；(d) 重度遊戲者也往往熟悉各式遊戲介面而具備跨遊戲平台的特質。據此，本研究建議，介面投入時間可以被視為遊戲表現的重要受測者分群基礎。

This study focuses on the gaming performances of gamers playing the same game using differing gaming interfaces. 32 subjects were grouped according to their annual accumulated time spent (interface engaging time for short) on three-game interfaces: touch-screen, keyboard, and gamepad. The subjects participated in research involving four types of game interfaces viewed as independent variables. Results show: (a) Interface engaging time has a significant influence on gaming performance. (b) The longer the engaging time on a certain interface, the better the gaming performance on said interface. (c) Except for the keyboard, a longer engaging time does not necessarily lead to easier adaptation to other interfaces. (d) Heavy gamers are familiar with all gaming interfaces and have the potential to play across interfaces. In view of the above, this study suggests that interface engaging time can be considered as a prominent method of subject categorization for research on gaming performance.
