Embodiment Construction

[0037] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 A diagram of the system. The block diagram of the system implementing the method of the present application is shown in the figure, which consists of an image display module, an eye movement signal detection module, a fixation point heat map generation module, a mouse button module, a fixation point detection module, an image scaling module, and an image dragging module constitute. Among them, the image display module presents the image to be operated; the eye movement signal detection module obtains the eye movement signal of the operator; the fixation point heat map generation module converts the eye movement signal into a fixation point heat map; the mouse button module obtains the operator's current view The left, middle, and right button events of the mouse made by the image; when the mouse button event is detected, the gaze p...

Abstract

The invention discloses an image zooming and dragging method based on an eye movement signal, and belongs to the technical field intersecting cognitive neuroscience and image processing. The present invention utilizes the eye tracker to acquire gaze point as the eye movement signal, and uses the gaze area as the zooming target area during the image zooming operation; and uses the gaze area to indicate the dragging direction during the image dragging operation, so that the sufficient eye movement signal is fast and convenient Features, combined with image processing technology and mouse button input, can achieve fast and efficient image zooming and dragging, effectively reducing the operator's operating intensity and time.

Description

technical field [0001] The invention discloses an image zooming and dragging method based on an eye movement signal, and belongs to the technical field intersecting cognitive neuroscience and image processing. Background technique [0002] Zooming and dragging images are the basic functions of human-computer interaction to realize image manipulation, and have important application value in the field of image processing involving human-computer interaction. In some special application fields, such as the fine processing or interpretation of images, the operator needs to process or interpret each area of ​​the large-scale image one by one. During the process, the local area of ​​interest needs to be zoomed and Drag and drop the entire large-size image. How to improve the efficiency of zooming or dragging to effectively reduce the operator's operating intensity has great practical value in special application fields such as fine processing or interpretation of images.
