Detailed Description
The technical scheme in the embodiment of the invention is clearly and completely described below by combining the attached drawings in the embodiment of the invention; it is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The method for acquiring the indication information by the indicating equipment provided by the embodiment of the invention specifically comprises the steps of acquiring the motion parameters of a screen cursor, acquiring the key operation of the indicating equipment and acquiring the roller operation of the indicating equipment.
Acquiring the motion parameters of a screen cursor
The principle of acquiring the motion parameters of the screen cursor by the indicating equipment provided by the embodiment of the invention is as follows:
in general, a user operates the pointing device while facing the screen. The direction from the user to the screen (or the direction from which the user faces, or the direction opposite to the direction from which the screen faces, hereinafter referred to as the "man-machine orientation") is calibrated in the y-axis direction of a coordinate system (hereinafter referred to as an external coordinate system) with the user (or the screen) as the origin. The distance and direction of movement that the pointing device communicates to the smart device should be the distance and direction of movement relative to the origin in the external coordinate system.
In the moving process of the indicating equipment, the moving distance and the moving direction detected by a displacement sensor in the indicating equipment are referenced to a coordinate system (hereinafter referred to as an internal coordinate system) calibrated inside the displacement sensor, so that the moving distance and the moving direction in an external coordinate system need to be converted; the moving distance in the internal coordinate system can be converted into the moving distance in the external coordinate system according to the proportional relation; specifically, the scaling factor c of the proportional relationship is a constant, and may be preset when leaving a factory, or may be updated and set by a user according to personal use habits through indicating device parameter setting software or an indicating device parameter adjusting device provided by a manufacturer; since the internal coordinate system and the external coordinate system have an included angle α, the moving direction of the internal coordinate system needs to be converted into the moving direction of the external coordinate system by adding the included angle α with the external coordinate system.
As described above, assuming that the movement distance X and the movement direction S acquired by the shift sensor of the pointing device are X and S, the movement distance X ' and the movement direction S ' of the screen cursor are S, and the predetermined scale factor of the movement distance X of the pointing device and the movement distance X ' of the screen cursor is c (constant), there are:
X’＝cX
S’＝S+α
that is, if the angle α between the external coordinate system and the internal coordinate system is known, the motion parameter of the screen cursor can be obtained.
According to the above principle, as shown in fig. 1, the specific steps of obtaining the motion parameters of the screen cursor are as follows:
wherein, the corresponding man-machine orientation information may include: the angle alpha between the external coordinate system for calibrating the orientation of the human machine and the internal coordinate system for calibrating the indicating equipment and/or whether the indicating equipment is operated by the left hand or the indicating equipment is operated by the right hand.
Specifically, the state information (i.e. the moving distance X and the moving direction S) of the pointing device can be obtained by a roller or a photo-emission detector of the prior art; and the man-machine orientation information can be acquired by adopting at least one of the following items:
(1) acquiring environment image information within a preset range, and determining an included angle alpha and/or determining whether a left hand or a right hand operates the indicating equipment according to the environment image information and preset structure, shape or color information of a human body or a screen;
specifically, the environment image information and the preset structure, shape or color information of the human body or the screen can be analyzed to directly estimate the included angle α, or the orientation of the human body can be calculated according to the environment image information and the preset structure, shape or color information of the human body or the screen, and then whether the left hand or the right hand operates the indicating device is judged to further estimate the included angle α;
or,
(2) acquiring environment image sequence information within a preset range, and determining an included angle alpha and/or determining whether a left hand or a right hand operates the indicating equipment according to the environment image sequence information and preset screen structure, shape, color information or human body motion information;
specifically, the environment image sequence information and the preset screen structure, shape, color information or human motion information may be analyzed to directly estimate the included angle α, or a process of an arm touching the pointing device from far to near may be determined according to the environment image sequence information and the preset human motion information, so as to determine the direction of the human body and whether the left hand or the right hand operates the pointing device, thereby estimating the included angle α.
specifically, if the motion parameters of the screen cursor include the moving distance X ' and the moving direction S ' of the screen cursor, and the predetermined scaling factor of the moving distance X of the pointing device and the moving distance X ' of the screen cursor is c (constant), then according to the above principle, and the state information (i.e. the moving distance X and the moving direction S) of the corresponding pointing device obtained in step 11, it can obtain:
X’＝cX
S’＝S+α
furthermore, according to the included angle α obtained in step 11, the motion parameter of the screen cursor can be determined.
