摘要： The present invention relates to a method and system for simulating a handle's motion. The method comprising: receiving detected acceleration values x(i), y(i) and z(i) of the handle in three directions; determining whether the acceleration values x(i), y(i) and z(i) in the three directions are noise interference with reference to a threshold value NT for noise interference; in the case that the acceleration values x(i), y(i) and z(i) are not the noise interference, determining angles α(i), β(i) and γ(i) during the handle's motion respectively from the acceleration values x(i), y(i) and z(i); and simulating the handle's motion on the basis of the angles α(i), β(i) and γ(i). The method and system according to the present invention poses a big challenge to the conventional operation by a mouse or a keyboard. They can simulate every motion of a user and reflect the motion on a role in a 3D game. It is also possible that virtual animation created by the method has outstanding reality and good real-time characteristics without additional hardware circuits, so that the user gets released from the restriction by the mouse and keyboard.

摘要： The present invention discloses a method and system for implementing a three-dimension positioning. The method comprises: receiving, by an optical sensor, infrared rays emitted from an infrared reference light source; and determining a position of the optical sensor with respect to the infrared reference light source based on attributes of the infrared reference light source in images obtained by the optical sensor, so as to implement a three-dimension relative positioning of the optical sensor. The method and system determine the position of the optical sensor with respect to the infrared reference light source by means of the attributes of the infrared reference light source in the images, which are simple in implementation, of a relatively low cost and can provide an excellent positioning function for application contexts of relative positioning (such as immersive video), which greatly improves the experience of a user.
