Problems solved by technology

[0006] The problem to be solved by the present invention is that when the attitude sensing equipment in the prior art uses its inertial device to measure the angular velocity or / and acceleration component to obtain the inclination angle to determine the coordinate change, the complex and large amount of calculation needs to consume more resources, resulting in a faster processing speed. slower and has higher power consumption

Embodiment 1

[0051] In this embodiment, the attitude sensing device is specifically an air mouse, and the inertial device is an acceleration sensor. Further, the acceleration sensor is a capacitive gravitational acceleration sensor, which includes at least two mutually perpendicular sensitive axes, one of which is sensitive to axis perpendicular to the ground plane. During specific implementation, a three-axis gravitational acceleration sensor is generally selected, and the sensitive axis perpendicular to the ground plane is recorded as the z-axis, and the other two sensitive axes are perpendicular to each other and are respectively perpendicular to the z-axis, which are respectively recorded as the x-axis and y-axis. The plane formed by the x-axis and the y-axis is parallel to the ground plane. Since the current requirement of the air mouse is only to realize a two-dimensional coordinate system on the screen, any two of the three axes can be used to meet the required requirements (determi...

Embodiment 2

[0134] to combine figure 1 , in this embodiment, the parameter of the sensitive axis in step S101 includes the coordinate value of the sensitive axis of the inertial device determined based on the inclination angle of the sensitive axis. The difference from Embodiment 1 is that in order to enable the determination of the spatial coordinates of the gesture-aware device in step S103 to achieve its positioning faster, this embodiment considers directly establishing the index value and based on the Correspondence between the coordinate values ​​of the sensitive axis of the inertial device determined by the inclination angle of the sensitive axis. Of course, the corresponding relationship between the index value and the coordinate value of the sensitive axis of the inertial device determined based on the inclination angle of the sensitive axis can also be stored in the read-only memory in the form of a table. In this embodiment, the This table is called a coordinate correspondence...

Abstract

An attitude sensing device and positioning method thereof and a mouse cursor control method, the attitude sensing device comprising at least one inertial device; the positioning method of the attitude sensing device comprises: establishing a corresponding relation between an index value and the parameter of a sensitive axis, the index value corresponding to the measured value of the sensitive axis of the inertial device, and the parameter of the sensitive axis comprising the inclination angle of the sensitive axis of the inertial device and trigonometric function value thereof and / or the coordinate value of the sensitive axis of the inertial device determined by the inclination angle of the sensitive axis; obtaining the measured value of each sensitive axis of the inertial device; querying the corresponding relation based on the index value corresponding to the obtained measured value, and determining the spatial coordinates of the attitude sensing device. The technical solution of the present invention can quickly position the attitude sensing device and reduce power consumption.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a gesture sensing device, a positioning method thereof, and a mouse pointer control method. 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 air mouse Came into being. The air mouse is an input device that operates the screen cursor (mouse pointer) like a traditional mouse, but it does not need to be placed on any plane, and the mouse pointer can be co...
