Problems solved by technology

However, in the prior art, either the gyro sensor measures the angular velocity of its sensitive axis and then uses the integral operation to obtain the tilt angle to determine the spatial coordinate change of the air mouse, or the acceleration sensor measures the acceleration components of each sensitive axis and then through inverse triangulation Obtaining the inclination angle by the function operation to determine the spatial coordinate change of the air mouse requires complex operations (integral operations, inverse trigonometric function operations, etc.), and most of these operations in

Example Embodiment

[0067] Example one

[0068] In this embodiment, the air mouse includes at least one inertial device, and the inertial device includes a gravity acceleration sensor. Further, the gravity acceleration sensor is a capacitive gravity acceleration sensor, which includes at least two mutually perpendicular sensitive axes, One of the sensitive axes is perpendicular to the ground plane. In the 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 perpendicular to the z axis, which are respectively recorded as the x axis and the y axis. The plane formed by the x-axis and y-axis is parallel to the ground plane. As the current air mouse meets the requirements only on the screen, it is actually a two-dimensional coordinate system, so any two of the three axes can meet the required requirements (deter...

Example Embodiment

[0133] Example two

[0134] The method for controlling the movement of the mouse pointer provided in this embodiment is based on the method for controlling the movement of the mouse pointer described in the first embodiment. The difference from the first embodiment is that the method for determining the spatial coordinates of the air mouse is different. Can be combined image 3 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. In order to be able to determine the spatial coordinates of the air mouse in step S103 to achieve faster positioning, it is considered in this embodiment to directly establish the index value and the inertial device determined based on the tilt angle of the sensitive axis Correspondence between the coordinate values ​​of the sensitive axis. Of course, the corresponding relationship between the index ...

Example Embodiment

[0140] Example three

[0141] On the basis of Embodiment 1 or Embodiment 2, the inventor considers that the movement of the air mouse includes not only acceleration, deceleration, or uniform movement, but also its movement trend (trajectory), which includes linear movement and non-linear movement. Linear movement, if it can be judged that the movement trend of the air mouse is linear movement, by reducing the reporting rate of the air mouse, the power consumption can be reduced without affecting the smoothness of the mouse pointer movement track.

[0142] Therefore, in this embodiment, the method of using the air mouse to control the movement of the mouse pointer further includes: identifying the movement trend of the air mouse by using index values ​​obtained after determining that the sensitive axis is stable. If the movement trend is a linear movement, Then the report rate of the air mouse is reduced. Specifically, identifying the movement trend of the air mouse by using the in...

Abstract

The invention discloses an air mouse and a method and a device for controlling the movement of a mouse pointer. The air mouse comprises at least one kind of inertia device, wherein the inertia device comprises a gravity acceleration sensor; and the method for controlling the movement of the mouse pointer comprises the following steps of: setting a report rate of the air mouse based on a vector sum of acceleration output values of various sensing axes of the gravity acceleration sensor; determining a space coordinate of the air mouse; correspondingly converting the determined space coordinate or variation thereof into a coordinate of the mouse pointer or variation thereof; and outputting the coordinate of the mouse pointer or the variation thereof at the set report rate so as to control the movement of the mouse pointer. By the technical scheme, the report rate can be dynamically adjusted according to actual movement conditions of the air mouse, so that the movement of the mouse pointer is controlled.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to an air mouse and a method and device for controlling the movement of the 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 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 contr...
