“鼠标终结者”问世

    下一个试验品是谷歌地球（Google Earth），也是完全依靠手势操作。霍尔茨向我展示了一幅山区地图。因为我经常在自己的智能手机、平板电脑和MacBook Pro上使用手势操作，所以这次我尝试在地图上的不同区域进行拖放。利用Leap，你所交互的不再是2D界面而是3D界面。在手机或平板上，进行上下左右方移动及缩放等动作可能需要好几个手势，但Leap也许只需一个动作即可完成。霍尔茨向我展示了如何通过轻轻地旋转一根手指来实现上述操作，所有动作只需将手指向上或向前移动即可。这一切感觉很直观，但我之前从未有过这种程度的体验。

    现在尚不清楚开发者能利用Leap开发出什么，也无法确定这款设备能否像Kinect一样，吸引到众多个人消费者、黑客甚至机器人科学家等用户。但如果Leap的最终发布版能不负众望，那么它必将为计算机界带来一次变革。

    Next was Google (GOOG) Earth, which again, was completely navigable by hand. Holz pulled up a map of a mountain region. Because I'd become used to gestures on my smartphone, tablet, and MacBook Pro, I tried zooming in on different areas of geography by pinching. With the Leap, you're not interacting with a 2-D surface but a 3-D space. So while actions like moving left or right, up and down, and zooming in or out might require multiple gestures on a phone or tablet, doing that with this device could be accomplished in one. To illustrate, Holz showed me how to do that by my rotating my finger slightly, all while moving it forward and up. It felt intuitive, but to a degree I'd never experienced before.

    It's too early to tell what developers will drum up and whether the device finds the kind of massive adoption Kinect has with consumers, hackers and even robotics scientists. But if the Leap lives up to expectations when the final version arrives, it's certainly got a shot at revolutionizing the desktop.
