Example Embodiment

[0024] As described in the background art, in the prior art, there are problems of asynchronous data transmission and processing between the space mouse and the receiving end, as well as a large amount of data transmission and poor reliability. For the above problems, the solution that can usually be thought of is: according to the various data collected in real time by the space mouse, various processing (including temperature drift compensation, correction of space coordinates, and the relationship between space coordinates and mouse pointer coordinates are directly completed at the end of the space mouse) Coordinate conversion between the two) to obtain the coordinates of the mouse pointer, and then send the coordinates of the mouse pointer obtained by processing to the receiving end, so as to realize the control of the mouse pointer.

[0025] However, if all processing is arranged on the side of the space mouse, it is necessary to enhance the data processing capability of t...

Abstract

The invention provides a data transmission method of a spatial mouse and a method for controlling a mouse pointer. The spatial mouse comprises an inertial component which is suitable for collecting space coordinate original data. The data transmission method of the spatial mouse includes the steps of converting the collected space coordinate original data into a quaternion, conducting data compensation processing on the obtained quaternion after the conversion and sending the quaternion processed through data compensation to a receiving end, wherein the data compensation processing includes temperature excursion. The method for controlling the mouse pointer includes the steps that the spatial mouse sends the quaternion processed through data compensation to the receiving end through the data sending method, and the receiving end restores the received quaternion into a space coordinate of the spatial mouse or the variable quantity of the space coordinate and converts the space coordinate into the coordinate of the mouse pointer or converts the variable quantity of the space coordinate into the variable quantity of the coordinate of the mouse pointer so that the mouse pointer can be controlled. Due to the adoption of the technical scheme, the problems that data transmission and data processing between the spatial mouse and the receiving end are not synchronous can be solved, the data transmission quantity can be reduced and reliability of data transmission can be improved.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a method for sending data of a space mouse and a method for controlling 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, the user wants to manipulate the mouse pointer in the air or realize applications such as multimedia TV playback and web browsing by manipulating the mouse pointer in the air, or for the target object (mouse pointer) in 3D games. A special form of expression of ), the control cannot be realized using only traditional sensors, so the space mouse came into being. The space mouse is an input device that can operate the screen cursor (mouse pointer) like...
