Problems solved by technology

During the movement of the gesture, when the user needs to select an item that is far away from the current position of the gesture, the gesture needs to move a long distance to complete the operation, which will increase the fatigue of the user and change the user experience. Difference

Embodiment

[0027] like figure 1 As shown, the abscissa represents the moving speed of the gesture in the air, and the ordinate represents the ratio of the moving distance of the gesture mapped to the interface to the moving distance of the gesture in the air.

[0028] A speed control method for mapping a gesture motion to an interface, comprising the following steps:

[0029] Step 1, set the camera as a front-end sensor for capturing gesture movements, and the camera can be a normal camera or a depth camera. The image sequence captured by the front-end sensor is analyzed and processed, and the position information of the gesture in each frame of the image sequence of the front-end sensor and the speed information of the current gesture movement are obtained.

[0030] Step 2, setting the motion speed of the gesture in the air to three levels, namely the first speed level, the second speed level and the third speed level.

[0031] Step 3, when the motion speed of the gesture in the air i...

Abstract

The invention discloses a method for controlling speed of mapping of a gesture movement to an interface. The method includes the following steps that the speed of the movement of a gesture in the air is changed, so that the ratio between movement distance of the gesture mapped to the interface and movement distance of the gesture in the air is changed; the movement speed of the gesture in the air is set as a first speed grade, a second speed grade and a third speed grade; when the movement speed of the gesture in the air is the first speed grade, the ratio between movement distance of the gesture mapped to the interface and movement distance of the gesture in the air is set as P1; when the movement speed of the gesture in the air is the third speed grade, the ratio between movement distance of the gesture mapped to the interface and movement distance of the gesture in the air is set as P2; and when the movement speed of the gesture in the air is the second speed grade, the ratio between movement distance of the gesture mapped to the interface and movement distance of the gesture in the air is set as P, the P increases with the increasing of the movement speed of the gesture in the air, and the P is larger than the P1 and smaller than the P2.

Description

technical field [0001] The invention relates to the field of human-computer interaction control, in particular to a speed control method for mapping gesture motion to an interface. Background technique [0002] In the non-contact human-computer interaction system, the human-computer interaction based on gesture control is an important link. Human-computer interaction based on gesture control is simple and convenient, and its commonly used operation method is gesture roaming. Gesture roaming refers to mapping the movement of gestures in physical space to the interface of the controlled object to realize the operation of the controlled object. The existing gesture motion mapping method is the direct mapping of gesture coordinates, that is, the position coordinates of the gestures in the image sequence captured by the sensor are mapped proportionally to the position coordinates of the controlled object in its motion interface. For example, in a common graphical user interface...
