我们讨论旨在支持三维神经外科可视化的双手用户界面。就其本身而言，该系统是一种“点设计”，是高级用户界面技术的一个示例。在这项工作中，我们认为，为了理解交互技术为何有效或无效，并提出新技术的可能性，重要的是超越点设计并引入对人类行为原则的仔细科学测量。特别是，我们认为“两只手通过并行工作节省时间”的常识观点可能并不总是思考双手界面设计的有效方法，因为双手不一定并行工作（双手操作有一个结构），而且两只手的作用不仅仅是比一只手节省时间（两只手为用户提供更多信息，并可以构建用户对任务的思考方式）。为了支持这些主张，我们提出了与神经外科医生合作开发的界面设计，该设计经过了广泛的非正式可用性测试，以及两项正式的实验研究，调查了双手虚拟对象操作的行为方面。我们希望这次讨论能够帮助其他人将我们的神经外科应用程序中的经验教训应用到未来的双手用户界面设计中。
We discuss a two-handed user interface designed to support three-dimesional neurosurgical visualization. By itself, this system is a “point design,” an example of an advanced user interface technique. In this work, we argue that in order to understand why interaction techniques do or do not work, and to suggest possibilities for new techniques, it is important to move beyond point design and to introduce careful scientific measurement of human behavioral principles. In particular, we argue that the common-sense viewpoint that “two hands save time by working in parallel” may not always be an effective way to think about two-handed interface design because the hands do not necessarily work in parallel (there is a structure to two-handed manipulation) and because two hands do more than just save time over one hand (two hands provide the user with more information and can structure how the user thinks about a task). To support these claims, we present an interface design developed in collaboration with neurosurgeons which has undergone extensive informal usability testing, as well as a pair of formal experimental studies which investigate behavioral aspects of two-handed virtual object manipulation. Our hope is that this discussion will help others to apply the lessons in our neurosurgery application to future two-handed user interface designs.
