Signal transmitting unit is used for producing control signal corresponding according to the user action that above-mentioned action recognition unit judges is come out, and sends to the signal receiving device of Digital Television.
Described Digital Television remote control equipment is not done special instruction to other functions, and it should comprise available remote control module usually.
Described acceleration transducer is not done special instruction to its model, but the acceleration of its all directions should obtain remote control equipment and on three-dimensional space direction, move the time.
Described action recognition unit is responsible for the acceleration signal that acceleration transducer obtains is analyzed, when the value of acceleration signal during greater than preset threshold value, then this signal is effective, is judged user's action then by this signal, as moving of " upper and lower, left and right ".
Described signal transmitting unit, the user action that comes out according to above-mentioned action recognition unit judges produces control signal corresponding, and such as with user's whipping to the right, remote control equipment is identified as the signal of " next program "; Whipping left, remote control equipment is identified as the signal of " a last program "; Upper and lower mobile remote control equipment can be identified as " volume increases, subtracts " signal respectively; The upset remote control equipment can be identified as " quiet " signal.Then the infrared dispensing device of these control signals by remote control equipment sent to Digital Television.
In addition, for preventing misoperation, described Digital Television remote control equipment should have individual shift knob, is responsible for the function of this acceleration transducer of opening and closing.
Equally, be the misoperation that prevents that the user from producing when the slight mobile remote control equipment, described action recognition unit should use predetermined threshold value when judging acceleration signal, when having only accekeration when a certain direction above this threshold value, think that just this signal is effective, otherwise will ignore this signal.
The remote control thereof that the embodiment of the invention provides, obtain the acceleration of gravity of space three-dimensional direction by acceleration transducer, and judge user action according to the component of acceleration that obtains, then produce and send control signal corresponding, realized utilizing gravity sensing function to make user's hand-held remote control device in direction in space, come Digital Television is carried out different controlling with different actions, and then provide a kind of brand-new man-machine interaction mode, bring more novel user experience, improve product competitiveness.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the method flow diagram of the Digital Television remote control equipment of a kind of embedded acceleration transducer of providing of the embodiment of the invention.
Fig. 2 is three-dimensional space direction X, the Y of the embodiment of the invention, the schematic diagram of Z.
Specific implementation method
The present invention will be further described below in conjunction with drawings and Examples, and the technical scheme in the embodiment of the invention is clearly and completely described, and obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiment that obtained under the creative work prerequisite.
For the user can be controlled Digital Television with the action on the three-dimensional space direction by hand-held remote control device, the embodiment of the invention provides a kind of remote control thereof, and as shown in Figure 1, its step comprises:
1, obtains component of acceleration by acceleration transducer;
Acceleration transducer in the embodiment of the invention can be with perception any time acceleration component values at space three-dimensional direction X, Y, Z (as shown in Figure 2).And this acceleration transducer has three read-only registers, is respectively applied for the storage acceleration component values on three directions at a time.For example, suppose that three registers are respectively accX, accY and accZ, the component of acceleration on the directions X that perceives can be stored among the register accX so, the component of acceleration on the Y direction that perceives is stored among the register accY, the component of acceleration on the Z direction that perceives is stored among the register accZ.
The microcontroller of remote control equipment inside can read the acceleration component values of any time by bus from these three registers, this acceleration component values is a signed number, the direction of symbology component of acceleration, the size of numeric representation component of acceleration.
As shown in Figure 2,
Directions X is exactly the horizontal left and right directions of remote control equipment, and is for just, left for negative to the right;
The Y direction is exactly the horizontal vertical direction of remote control equipment, and is for just, back for negative forward;
The Z direction is exactly the spatial vertical direction of remote control equipment, upwards for just, down for negative;
