尽管双手交互的好处已被证明，但大多数平板电脑只使用一只手进行交互，以释放另一只手进行支持。在一项初步研究中，我们确定了五个允许同时支持和互动的按键，并注意到用户经常改变姿势以对抗疲劳。然后，我们设计了BiTouch设计空间，它在运动链模型中引入了用于与手持平板电脑交互的支撑功能，并开发了BiPad，这是一个用于创建与支持手的拇指或手指进行双向手部平板电脑交互的工具包。我们进行了一项对照实验，以探索平板电脑的方向和手的位置如何影响三种新技术：双手敲击、手势和和弦。双手敲击在横向和纵向上都超过了我们的单手控制条件；双手和弦和手势仅在肖像模式下；拇指的表现优于手指，但更累，也更不稳定。BiTouch和BiPad共同为在手持平板电脑上设计双指甲交互提供了新的机会。
Despite the demonstrated benefits of bimanual interaction, most tablets use just one hand for interaction, to free the other for support. In a preliminary study, we identified five holds that permit simultaneous support and interaction, and noted that users frequently change position to combat fatigue. We then designed the BiTouch design space, which introduces a support function in the kinematic chain model for interacting with hand-held tablets, and developed BiPad, a toolkit for creating bimanual tablet interaction with the thumb or the fingers of the supporting hand. We ran a controlled experiment to explore how tablet orientation and hand position affect three novel techniques: bimanual taps, gestures and chords. Bimanual taps outperformed our one-handed control condition in both landscape and portrait orientations; bimanual chords and gestures in portrait mode only; and thumbs outperformed fingers, but were more tiring and less stable. Together, BiTouch and BiPad offer new opportunities for designing bimanual interaction on hand-held tablets.
