介绍了Leapmotion交互设备的结构及运行机制，在该设备产生的交互空间中的x-y平面上定义8个方向的方向链码，通过该设备检测手指在空间中的位置变化，确定手指的移动方向，并结合方向链码定义动态书空手势。为了消除手指在空间运动的不稳定性而导致的噪声干扰，将手指在平面上的位置信息映射到计算机屏幕上显示出手指的移动轨迹，对轨迹进行分段处理，根据分段的比重提取主要移动方向描述输入手势，采用顺序匹配算法对输入手势与模板手势进行匹配，识别输入的书空手势。

The structure and operation mechanism of the Leapmotion interactive device are introduced,and the 8-direction chain code is defined on the x-y plane of the device.The change of spatial position of the fingertip is detected to determine its movement direction,which is combined with the direction chain code to customize dynamic space-writing gestures.In order to eliminate the noise of the finger spatial motion,the spatial position of the fingertip is mapped as the computer screen position to display the trajectory of fingertip.Then,the trajectory is split into segmentations to extract the main direction of movement.The order matc-hing algorithm is applied to compare the input gesture and templet gestures toidentify the input space-writing.
