Abstract

The embodiment of the invention relates to the field of computer application technology, and discloses a non-contact screen interaction method and system. Wherein, the system includes a computer, a projector, a video camera for capturing image information projected on a screen, and two laser pointers for generating laser beams projected on the screen, and the system also includes: a laser point positioning module , used to map the camera image coordinates of the two laser points projected by the two laser pointers on the screen to the computer screen coordinates; the manipulation object recognition module is used to identify the manipulation objects pointed to by the two laser pointers; the manipulation The action recognition module is used to identify the manipulation actions of the two laser pointers; the interactive drive module is used to convert the manipulation actions into manipulation instructions for the manipulated object recognizable by the computer and transmit them to the computer, and the computer executes the manipulation instructions. control instructions. Through the embodiment of the present invention, the non-contact screen interactive operation can be made more natural and humanized.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a non-contact screen interaction method and system. Background technique [0002] The interactive large screen is a popular demonstration interactive system in recent years. Users can manipulate the content displayed on the large screen through certain means, such as flipping pages, moving, zooming, etc. Accurately capturing and understanding the intention of the user's manipulation action is the key to realizing the interaction. At the same time, the manipulation action is natural and humanized, conforms to the user's habits, and meets the needs of the user's interactive experience. It is also a hot spot in the current research on large-screen interaction. [0003] One of the existing technical solutions is that the user holds a single laser pointer to draw a certain pattern on the large screen, and the camera captures and recognizes the trajectory of the laser poi...
