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

Abstract

A data processing method for a space mouse and a control method for a mouse pointer. The space mouse comprises an inertial device which is suitable for collecting space coordinate data. The data processing method for a space mouse comprises: recording space coordinate data which is collected at the last time before an inertial device is closed; after the inertial device is restarted, acquiring a compensation value of current space coordinates, the compensation value of the current space coordinates being the difference value of the space coordinate data which is collected at the previous time and the recorded space coordinate data; and using the compensation value of the current space coordinates to compensate the currently collected space coordinate data, so as to obtain an output value of the current space coordinate data. The technical solution of the present invention can effectively solve the problem that the space coordinate data output by a space mouse has an error, so that the space coordinate data output by the space mouse is accurate and reliable, and the locating 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
