Data processing method for space mouse and control method for mouse pointer

Abstract

The invention discloses a data processing method for a space mouse and a control method for a mouse pointer. The space mouse comprises an inertial device suitable for acquiring space coordinate data. The data processing method for the space mouse comprises the following steps of recording the space coordinate data which are acquired the last time before the initial device is closed; acquiring a compensation value of current space coordinates after the initial device is reopened, wherein the compensation value of the current space coordinates is a difference between the space coordinate data which are acquired last time and the recorded space coordinate data; and compensating the currently-acquired space coordinate data by adopting the compensation value of the current space coordinates so as to obtain an output value of the current space coordinate data. According to the technical scheme provided by the invention, the problem that errors exist in the current space coordinate data outputted by the space mouse can be effectively solved, so that the current space coordinate data outputted by the space mouse are accurate and reliable and the positioning accuracy of the space mouse is improved.

Description

technical field [0001] The invention relates to the technical field of a space mouse, in particular to a data processing method of a space mouse and a control method of a mouse pointer. Background technique [0002] At present, the positioning of the computer mouse pointer is mostly realized by optical sensors or laser sensors. These sensors are all based on the principle of physical optics, so that the sensors need to be realized by platforms such as desktops. But in many occasions, such as in computer multimedia teaching, users want to manipulate the mouse pointer in the air or realize multimedia TV playback, web browsing and other applications by manipulating the mouse pointer in the air, which cannot be realized only by using traditional sensors, so the space mouse Came into being. The space mouse is an input device that operates the mouse pointer (screen cursor) like a traditional mouse, but it does not need to be placed on any plane, and the mouse pointer can be contr...

Problems solved by technology

[0004] But in the process of actual use, when the space mouse is turned off, the movement process of the space mouse can no longer be detected, and when the space mouse is turned on again, its coordinate zero point cannot be compared with the coordinate zero point before the space mouse is closed coincide, this is because the initial point of the space mouse, that is, the coordinate zero point is assumed by the system of the space mouse, and when the space mouse is turned on each time, the system re-determines the coordinate zero point, and the coordinate zero point determined afresh is very If it is difficult to coincide with the coordinate zero point before closing the space mouse last time, there will be a problem with the initial point of the space mouse at this time, and the space coordinates of the space mouse obtained on this basis will have errors, and then the determined There will be errors in the position and posture of the space mouse, and there will be errors in mouse positioning
