Embodiment 1
[0054] Example 1: One-way movement
[0055] One-way movement is the most widely used movement trend in the existing touch screen technology. In the existing touch screen technology, the judgment of the user's operation behavior can be completed by recording the trajectory of the finger sliding on the screen. However, in the present invention, fingers or palms slide in space without directly touching the touch screen, which cannot be realized by existing judgment techniques.
[0056] In the present invention, the method for judging the user's operation behavior of one-way movement is as follows: Figure 4 shown.
[0057] One-way motion is characterized by one or more fingers operating parallel to a certain coordinate plane or obliquely. In this case, all reference points at time 1 to time M The movement trajectories over time are roughly the same. If the entire trajectory is differentiated, the change trend of the coordinates of all points at a certain moment is selected f...
Embodiment 2
[0067] Example 2: Multi-directional movement
[0068] Multi-directional movement is also a relatively common user operation behavior. In the existing touch screen technology, the trajectory of the hand can be judged by the number of contacts at the initial moment and the trajectory of the touch, and then the user's behavior can be judged according to the trajectory.
[0069] However, in the three-dimensional space, like the one-way movement, the user's finger movement trajectory is formed in the three-dimensional space, and does not touch the touch screen.
[0070] Figure 5 A flow chart for illustrating the judging process of the user's operation behavior of the multi-directional motion.
[0071] To determine the user's operation behavior, it is first necessary to determine how many fingers are within the measurement range of the screen (S501).
[0072] Judging the number of fingers can be achieved by the following method, that is, for time 1 The coordinates of all points ...
Embodiment 3
[0075] Example 3: Turn
[0076] Rotation is an operation behavior of the user that does not exist in the two-dimensional space, and is a movement trend unique to the 3D space. Rotation is a relatively free coordinate change trend. The user's hand can rotate in front of the screen in any posture around the wrist. The trajectory of each reference point is similar to an irregular arc, and it is impossible to judge the hand rotation simply from the trend of a single coordinate change.
[0077] Figure 6 It is a flow chart for explaining the process of judging the rotation behavior of the user's gesture.
[0078] First, the present invention preliminarily judges whether the user's gesture is rotating (S601). The judgment method is to perform projection analysis on the coordinates of all points. Specifically, the time 1 to time M moment of D 1 to D N The coordinates (that is, the coordinate data of all points) are respectively projected onto the three coordinate planes. At ...
