Problems solved by technology

[0004] The conference speaker can link the computer with a large liquid crystal display, and use the mouse of the computer to indicate the position he is explaining. However, in order to mark the position that the conference speaker is explaining, it is not necessary to use an additional computer resource. It is convenient, so it is necessary to find a solution

Abstract

Disclosed is an indicator display and control method adaptive to a portable computation device and a display device containing a screen. The method includes the steps of A, allowing the portable computation device to produce a triggering signal to trigger the display device to display an indicator image in an initial position of the screen; B, on the basis of the triggering signal, allowing the portable computation device to produce a motion parameter group corresponding to the motion of the portable computation device; C, according to the motion parameter group, allowing the portable computation device to compute the displacement of the indicator representing the displacement of the indicator image on the screen; D, according to the displacement of the indicator and the resolution of the display device, allowing the display device to compute a fresh position of the indicator image displayed on the screen; E, allowing the display device to display the indicator image in the fresh position of the screen.

Description

technical field [0001] The invention relates to a method for displaying and controlling an indicator, in particular to a method for displaying and controlling an indicator based on a portable computing device. Background technique [0002] Liquid crystal display is the most mature, most widely used, industrialized and still developing rapidly among many flat panel displays. With the price of LCD monitors falling and the rise of high-definition movies, large LCD monitors have gradually become mainstream. [0003] The display equipment in the current conference room is also gradually replaced by large liquid crystal displays. Due to the structure of the polarizer in the liquid crystal display, when the conference speaker wants to use the laser pointer to explain the position being explained, the laser pointer produces The beam is blocked by the polarizer and cannot be reflected, so meeting presenters must use other means to indicate where they are presenting. [0004] The co...
