Non-contact type computer operating method based on Leap Motion

The invention relates to a non-contact type computer operating method based on a Leap Motion. The method comprises the following steps that 1 data are collected by the Leap Motion in an infrared LED and gray scale camera mode, and after algorithm treatment is conducted, corresponding hand data are generated; 2 by treating hand data collected by the Leap Motion, and two different gestures, namely a natural gesture and a track gesture, are obtained by different judgment standards and identification methods; 3 a computer operation is matched; 4 the computer operation is executed. The non-contact type computer operating method has the advantages that information input is carried out by detecting motions of a human body, so that the whole operating and controlling process is free; a user can use the method under multiple environments freely, and operation and control can be achieved on a computer only need to carry out a simple gesture motion by the user; a somatosensory technology is applied to the operation for a computer equipment system level for the first time, and the defects that delay of a Kinect is high, and close-range precise recognition cannot be well conducted are made up.
