Problems solved by technology
For ordinary forward projection display technology, the brightness of the projection is low, and the projection screen is diffuse reflection, so it is easier to distinguish the laser point from the normal display content of the screen
But when the projection screen is replaced by other self-luminous screens, it is difficult to distinguish the screen content from the laser dots

The present application provides a screen control method and apparatus, wherein the method includes determining actual position coordinates of a trajectory of an invisible laser beam in a screen corresponding to the screen image based on a received screen image including the trajectory of the invisible laser beam; the invisible laser light and the visible light forming an indication beam, and theindication beam being used for prompting the position indicated by the user; generating a control command for controlling display of the screen according to a key command issued together with the invisible laser and the actual position coordinates; the control command being returned to the screen control system of the screen to realize the control of the screen. The embodiment of the present application realizes the control of the screen by a user through an invisible laser, and improves the precision of the screen control.
Description
technical field [0001] The present application relates to the technical field of screen control, and in particular, to a screen control method and device. Background technique [0002] The large-screen interactive system can bring intuitive, novel and more convenient presentation effects. Users can manipulate the demonstration content in a non-contact way, which is more humanized and can also meet the needs of users for interactive experience. [0003] In the existing large-screen interactive systems, red laser remote control is mostly used to interact with the large screen. For ordinary forward projection display technology, the brightness of the projection is low, and the projection screen is diffuse reflection, so it is easier to distinguish the laser point from the normal display content on the screen. But when the projection screen is replaced with other self-illuminating screens, it is difficult to distinguish the screen content from the laser dots. Contents of the...
