Problems solved by technology

When the remote control device rotates left and right with its own central axis, it is regarded as a "tilt" that should not appear by the remote control device, so an algorithm for tilt compensation is given to correct it, because the remote control device does not have absolute orientation capabilities , and the motion trajectories that can be obtained are relative, so it is difficult to distinguish whether such a rotation behavior is intentional or unintentional, so it is too easy to confuse and generate wrong instructions
[0004] For this reason, remote control devices such as nine-axis three-dimensional remote controllers or three-dimensional remote control devices using three-axis gravitational acceleration sensors, three-axis gyroscopes and three-axis geomagnetic sensors have emerged, which can solve the problems existing in the above-mentioned six-axis remote control devices, such as in 2010. The patent application number 200910105336.3 published on August 11, titled "Control Method and Its Device and System", but this patent only converts rotation into control commands, and in actual use there is not only rotation but also linear d

Embodiment 1

[0048] In this embodiment, the fixed pointing is directly ahead relative to the reference pointing as an example, and the volume is controlled by remote control.

[0049] S2-1: First sense the rotation change data of the three-dimensional inertial remote control device 100 to judge the start and stop of the command. Rotating the remote control device 100 clockwise starts an input command, and stopping clockwise or counterclockwise is a stop input command operation. Then sense the displacement change data of the three-dimensional inertial remote control device 100 to determine the command size. The displacement change data includes displacement direction and displacement speed. Speed ​​controls how much the volume changes. Finally, the rotation change data and displacement change data during the rotation and displacement change process are recorded. In this use process, the volume can be controlled only by controlling the rotation direction and displacement of the three-dimen...

Embodiment 2

[0051] In this embodiment, the fixed pointing is directly above the reference pointing as an example to control the size of the channel selection.

[0052] S2-2: First sense the displacement change data of the three-dimensional inertial remote control device 100 to judge the start and stop of the command. The displacement change data is the displacement direction. Stopping the upward movement or the displacement in the positive downward direction is the stop of the input command. Then sense the clockwise or counterclockwise rotation change data of the three-dimensional inertial remote control device 100 with a fixed pointing as the axis to determine the command size. The rotation change data includes the rotation direction, rotation angle, and rotation speed, such as clockwise rotation. In order to control the increase of the size of the channel selection, the counterclockwise rotation direction is to control the decrease of the channel selection, and the size of the channel s...

Embodiment 3

[0054] In this embodiment, the fixed pointing is taken as an example to be directly to the left relative to the reference pointing, which is mainly applied to the control of the game interface.

[0055] S2-3: In the present embodiment, the start and stop of the command is controlled by the switch key. Simultaneously sense the rotation change data and displacement change data of the three-dimensional inertial remote control device 100 to determine the command size. The rotation change data includes the rotation direction, the rotation angle, and the speed of rotation. The displacement change data includes the displacement direction, the displacement size, and the movement speed. Simultaneous sensing of rotation change data and displacement change data can effectively simulate special boxing actions such as spiral forward, spiral backward, spiral up and spiral down in the game interface, and avoid the need to simultaneously control upward, downward and downward in the existing ga...

Abstract

The invention discloses an input method of a three-dimensional inertia remote control device and the three-dimensional inertia remote control device. The input method includes the steps that the fixed pointing direction of the three-dimensional inertia remote control device is determined, and posture data of the fixed pointing direction are recorded; rotation and displacement changes of the three-dimensional inertia remote control device are sensed, and rotation change data and displacement change data of the rotation and displacement changes are recorded; the posture data of the fixed pointing direction, the rotation change data and the displacement change data are combined into a code, and a control instruction corresponding to the code is searched for through a database; the control instruction of the three-dimensional inertia remote control device (100) is sent. According to the input method, the posture data of the fixed pointing direction, the rotation change data and the displacement change data are used for being processed to be the control instruction so that a mainframe controlled by the device can be controlled. The complexity of using buttons can be effectively reduced, using is easy and convenient, and the application range is wide.

Description

technical field [0001] The invention relates to a remote controller and a remote control method thereof, in particular to an input method of a three-dimensional inertial remote control device and the three-dimensional inertial remote control device. Background technique [0002] Existing 3D remote controllers or 3D remote control devices use a combination of an acceleration sensor and a gyroscope or a combination of an acceleration sensor, a gyroscope and a geomagnetic sensor to sense a motion trajectory in a three-dimensional direction. Among them, the acceleration sensor is an electronic device that can measure the acceleration of gravity. The gyroscope is a sensor for angular motion that uses the moment of momentum of a high-speed rotating body to sense the shell relative to the inertial space and is orthogonal to the rotation axis. The geomagnetic sensor senses The magnetic field and / or the earth's magnetic field provide an absolute reference for the sensing of the three...
