Main control device, remote control device, remote control indicating system and method

Abstract

The invention relates to the technical field of electronics and discloses a master control device, a remote control device, and a remote control indicating system and method. At least one master control device and at least one remote control device establish wireless connection. The at least one master control device configures interaction parameters for the at least one remote control device, wherein the interaction parameters at least include cursor movement parameters. The remote control devices send own displacement data acquired by the remote control devices to the master control devices. The master control devices control movement of cursors on a screen of the master control devices according to the displacement data and the cursor movement parameters, i.e., users can give instructions in a cursor mode on the master control devices through the remote control devices, and control the displacement changes of the remote control devices to move the cursors of the master control devices. Accordingly, the cursors of the master control devices can be controlled through wireless connection established by the master control devices and the remote control devices, thus allowing a plurality of users to control the cursors of the master control devices independently.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a main control device, a remote control device, a remote control indicating system and a method. Background technique [0002] At present, projection presentations are very common, whether it is a unit meeting or teaching in a school, it will be applied. The use of a laser pointer during a projection demonstration can easily indicate the current lecture content on the projected large screen without being limited by the position, and it is more effective to combine the projection demonstration to do a good job in teaching or speech. [0003] Generally speaking, a projector is equipped with only one laser pointer, that is, only one speaker is allowed to operate; other participants can only express orally, but cannot indicate their own expression content on the projection screen, which is not conducive to their own expression being recognized by others. Understanding and thinki...

[0003] Generally speaking, a projector is equipped with only one laser pointer, that is, only one speaker is allowed to operate; other participants can only express orally, but cannot indicate their own expression content on the projection screen, which is not conducive to their own expression being recognized by others. Comprehend and think against others to keep up with what you have expressed

If a projector is equipped with multiple laser pointers, the number of people in each meeting is variable, which may cause waste of resources
