Method and system for implementing two-dimensional and three-dimensional pointer needle utilizing infrared image sensing

Abstract

The invention provides a method and a system for utilizing infrared image sensing to realize relative coordinates or absolute coordinates, as well as two-dimensional or three-dimensional pointers. The system comprises an infrared emission module and at least one infrared image sensing module which is connected with a host computer connected with a display screen. When the system is in use, an initial position of a two-dimensional or three-dimensional pointer is displayed on the display screen, and the infrared emission module in an induction zone of the infrared image sensing module sends out an infrared signal of a positioning light spot at the moment; then according to the imaging of the positioning light spot in the infrared image sensing module, the two-dimensional or three-dimensional coordinate of the of the positioning light spot is worked out; and according to the acquired coordinate data, the moving distance and moving direction of the position of the two-dimensional or three-dimensional pointer on the display screen are determined, so as to ensure that the position of the two-dimensional or three-dimensional pointer on the display screen follows the move of the infrared emission module to move in real time. The system has the advantages of convenient, natural, visual and clear operation, little mechanical wear, long life span and low cost.

Description

technical field [0001] The invention relates to a display screen pointer technology, in particular to a method and technology for infrared two-dimensional and three-dimensional pointers capable of realizing the display screen pointer function, and in particular to a system for realizing pointers by using infrared emission and infrared image sensing. Background technique [0002] In today's operating systems with display screens, especially computer operating systems, pointing devices have become an integral part of them. The pointing device can transmit the information of its location to the operating system in real time, so that the operating system can use the pointing device to define a pointer on the screen. Pointing, dragging, single-clicking, double-clicking and other operations are completed by using the indication of the pointer, which makes the operation of the system more convenient and intuitive, and makes it easier and more convenient for people to implement the ...
