The present invention further provides an operation method of a universal remote control device automatically configured through spatial orientation sensing, referring to fig. 6, the operation method specifically includes:
step 1, a starting and standby stage: starting up the universal remote control device and entering a standby state;
step 6, the user aims the universal remote control device at the target equipment in a certain direction;
step 7, identification and matching stage: whether a universal remote control aimed at a target device at a certain orientation is matched to the target device; if the target equipment can not be identified and matched, entering a configuration stage of step 8; if the target equipment can be identified and matched, the method of the step 9 is adopted to complete the identification and the matching;

The universal remote control device inquires whether configuration is needed, and if the configuration is not needed, the step 4 is returned; if the configuration is needed, the user aims the universal remote control device at the target equipment and configures the target equipment;
referring to fig. 4-8, the user aims the universal remote control at the target device and configures the target device. Specifically, the motion and space sensing unit in the universal remote control device tracks the current spatial information of the universal remote control device at any time, the spatial information is relative information based on reference information, for example, fig. 3, the reference position is marked as a coordinate (0,0,0), then in a three-dimensional space formed by x, y and z axes, the current universal remote control device U moves by distances of x1, y1 and z1 on the x, y and z axes, that is, moves to the position shown in fig. 7, and then the current spatial position is the first spatial position (x 1, y1, z 1);
the motion and space sensing unit in the universal remote control device also tracks and acquires the deflection angle of the universal remote control device relative to the reference direction at any time, namely the first space direction included angle shown in fig. 5;
moreover, the motion and space sensing unit also tracks the pitch angle of the universal remote control device at any time, for example, in fig. 7, the reference horizontal plane obtained in the calibration stage is 0 degree, and if the universal remote control device aiming at the target equipment is 30 degrees above the reference horizontal plane at the moment, the pitch angle obtained by the motion and space sensing unit is the elevation angle = 1 is 30 degrees, and is recorded as = 1=30 degrees; assuming that the universal remote control device aiming at the target equipment is downward 20 degrees relative to the reference horizontal plane at this time, the pitch angle acquired by the motion and space sensing unit is 20 degrees of depression and is recorded as ≈ 1= -20 degrees.
When a user holds the universal remote control device to aim at the target equipment, selecting and confirming the name and the model of the corresponding target equipment on a display screen of the universal remote control device; after the user finishes the selection, the spatial position management unit associates the spatial information of the universal remote control device at the moment, namely a first spatial orientation (x 1, y1, z 1), a first spatial direction included angle and a first pitch angle & lt 1 & gt with corresponding target equipment and stores the spatial information in the storage unit;
at the moment the user configures the universal remote control device, the user is required to make settings at a distance from the target apparatus. For example, in fig. 7, the user is required to set at a distance of 3 meters from the target device, i.e. the side length a is 3 meters; or the user is required to input the distance between the universal remote control device and the target equipment during the configuration operation and the distance is stored in the storage unit, namely, as shown in fig. 7, the user input side length is a =3 meters; or a laser ranging probe is arranged in the universal remote control device, the laser ranging probe automatically measures the distance between the universal remote control device and the target equipment during configuration and stores the distance in a storage unit, namely the side length a =3 m measured by the laser ranging probe of the universal remote control device.
Referring to fig. 7, the spatial coordinate of the reference point 0 is (0,0,0), the current spatial orientation of the universal remote control device U obtained by the motion and space sensing unit is a first spatial orientation (x 1, y1, z 1), and the distance from the universal remote control device U to the target apparatus a is a side length a (the side length a may be a distance required to be set, a distance input by a user, or a distance measured by a laser ranging probe); a first spatial direction included angle of the universal remote control device relative to the reference direction D; universal remote controllerA first pitch angle of the control device relative to a reference horizontal plane is less than 1; then the spatial position management unit calculates the spatial orientation of the target device a as (x) based on the above-mentioned conditions, which are known A ，y A ，z A ) And the calculation result is stored in the storage unit.
After the related information of the configuration stage is obtained and calculated, the configuration of the universal remote control device U and the target equipment A is completed, and the spatial position management unit enables the spatial orientation of the target equipment A to be (x) A ，y A ，z A ) The name and the model of the target device A, the remote control parameters of the target device A and the operation interface are associated and stored in the storage unit. For other target devices (B, C, d.... Et al), the same method can be used to complete the relevant configuration. Thereby realizing the configuration of the universal remote control device and different target devices and establishing information association.
Step 9, identification and matching stage: when the user picks up the universal remote control device, the spatial position management unit of the universal remote control device searches the target equipment related to the spatial orientation information according to the spatial orientation information of the identified target equipment. And when the matched target equipment is found, informing the remote control unit to automatically set corresponding remote control parameters and an operation interface to realize the remote control of the target equipment.
Specifically, referring to fig. 8, when the user holds the universal remote control device U and aims at the target equipment a, the motion and space sensing unit acquires the current spatial orientation of the universal remote control device U, i.e., the second spatial orientation (x 2, y2, z 2), the second spatial included angle, and acquires the pitch angle ≦ 3 of the universal remote control device U with respect to the reference horizontal plane at that time, due to the spatial orientation (x 2) of the target equipment a A ，y A ，z A ) Has been calculated in the configuration stage and stored in the memory unit, so that the universal remote control unit U is based on the spatial orientation of the reference point O (0,0,0), the current second spatial orientation of the universal remote control unit U (x 2, y2, z 2), the second spatial orientation angle, the spatial orientation of the target device A (x A ，y A ，z A ) The angle 4 and the angle 5 can be calculated; the included angle between the target equipment and the reference horizontal plane at the moment can be calculated through the angle 4 and the angle 5Alpha, namely ≈ alpha = 90-4-5, comparing the calculated included angle ^ alpha with a pitch angle ^ 3 of the target equipment A relative to a reference horizontal plane, which is acquired by the motion and space sensing unit, if the included angle ^ alpha and the pitch angle 3 are the same, identifying the target equipment A and completing the matching of the universal remote control device U and the target equipment A, so that the remote control unit automatically sets the universal remote control device as the remote control parameters and the operation interface of the target equipment A to realize the remote control of the target equipment A.
It should be noted that, since different target devices are usually placed at different positions, the spatial orientation (x) of different target devices A ，y A ，z A ) Is different, so that the universal remote control device can be accurately matched to the corresponding target device through the matching process described above. Of course, the situation that the two target devices are placed in close proximity is not excluded, for example, a television and a set-top box may be placed together, in this case, the universal remote control device will recognize two matched devices, and at this time, the user only needs to select the corresponding device on the operation interface of the universal remote control device. If the placing positions of a plurality of target devices are close to each other, the user can select the target devices when a plurality of matched target devices are identified.
Furthermore, in the matching process, error redundancy is set for the universal remote control device, and when the comparison value of the calculated included angle alpha and the pitch angle acquired by the motion and space informing unit is in the error redundancy range, the matching is considered to be successful. For example, a match may be deemed successful when the motion and spatial sensing unit of the universal remote control device obtains that the target device has a pitch angle of 30 degrees relative to a reference level and the included angle calculated by the match is 32 degrees. The specific error redundancy can be set according to specific needs, and is not particularly limited in this patent.
Step 10, remote control stage: and when the corresponding target equipment is identified in the preparation stage, the user operates the remote control device to operate the target equipment, and the user moves or puts down the universal remote control device after the operation is finished.
The technical solutions of the present invention are described above, and all the alternatives which do not depart from the essence of the technical solutions of the present invention should be within the scope of the claims of the present invention.
