进行了一项用户研究，以比较移动的设备的三种地图导航方法的性能。这些方法是操纵杆导航，动态窥视孔方法没有视觉上下文，和魔术透镜范例使用外部视觉上下文。操纵杆方法是熟悉的滚动和平移虚拟地图保持设备本身静止。在动态窥视孔方法中，设备相对于外部参考系移动并且地图相对于外部参考系固定，但是在设备的显示器之外不存在视觉信息。魔术透镜方法通过图形覆盖来增强外部内容，从而在设备显示器外部提供视觉上下文。这里，设备的运动也用于引导导航。我们在一项研究中比较了这些方法，通过问卷调查测量用户的性能，运动模式和主观偏好。研究表明，动态窥视孔和魔术透镜互动的优势，在搜索时间和搜索空间的探索程度方面的操纵杆互动。
A user study was conducted to compare the performance of three methods for map navigation with mobile devices. These methods are joystick navigation, the dynamic peephole method without visual context, and the magic lens paradigm using external visual context. The joystick method is the familiar scrolling and panning of a virtual map keeping the device itself static. In the dynamic peephole method the device is moved and the map is fixed with respect to an external frame of reference, but no visual information is present outside the device's display. The magic lens method augments an external content with graphical overlays, hence providing visual context outside the device display. Here too motion of the device serves to steer navigation. We compare these methods in a study measuring user performance, motion patterns, and subjective preference via questionnaires. The study demonstrates the advantage of dynamic peephole and magic lens interaction over joystick interaction in terms of search time and degree of exploration of the search space.
