Exemplary method
The first embodiment of the invention provides a display terminal control method which can be applied to a television. As shown in particular in fig. 1, the method comprises:
step S100, obtaining position information of the remote controller, and determining key layout information of the remote controller according to the position information.
Specifically, the remote controller in this embodiment can display remote controller keys at 360 ° all, the remote controller keys use virtual keys to replace traditional physical keys, the remote controller watch case uses display materials to replace, the remote controller uses the upward face as the key display face when displaying virtual keys, and uses one end close to the display terminal as the key layout top. For example, when the front side of the remote controller is upward and the top end of the remote controller is close to the display terminal, the layout state of the remote controller keys is shown in fig. 2, that is, the front side of the remote controller is taken as a key display surface and the top end of the remote controller is taken as the key layout top; when the remote controller is turned up and down, that is, the back surface of the remote controller faces upwards and the bottom end of the remote controller is close to the display terminal, the layout state of the keys of the remote controller is shown in fig. 3, that is, the keys of the remote controller take the back surface of the remote controller as a key display surface and the bottom end of the remote controller as a key layout top.
The position information comprises distance information of the remote controller relative to the display terminal and front and back information of the remote controller, wherein the distance information and the front and back information are determined in various manners. As shown in fig. 4, the side face of the remote controller key in this embodiment includes a power key, the bottom includes a type-c charging interface, the dotted circles on the front and back represent infrared emitters, and the infrared emitters in the actual product are disposed inside the remote controller, send infrared signals through the side edge, and the color is integrated with the remote controller. When distance information is determined, a plurality of infrared transmitters on the remote controller respectively transmit infrared signals to the display terminal, the display terminal can determine the distance information of the remote controller relative to the display terminal according to the receiving time of the infrared signals after receiving the infrared signals, and in order to avoid mutual interference of the infrared signals with the same wavelength, the wavelengths of the infrared signals transmitted by the infrared transmitters are different. For example, as shown in fig. 4 and fig. 5, four infrared transmitters are disposed on the remote controller, when determining the distance information, infrared signals are respectively transmitted to the display terminal through the four infrared transmitters, and after the display terminal receives the infrared signals, the distance information from each transmitting point to the receiving point can be respectively determined according to the four received infrared signals.
Since the remote controller in this embodiment uses the upward side as the key display surface when the keys of the remote controller are displayed, and uses the end close to the display terminal as the key layout top, when the position information of the remote controller, that is, the distance information of the remote controller relative to the display terminal and/or the front and back information of the remote controller, changes, for example, when the remote controller is turned upside down, the distance information of the remote controller relative to the display terminal and the front and back information of the remote controller are both changed, the key layout state of the remote controller is changed from using the front side of the remote controller as the key display surface and the top side of the remote controller as the key layout top to using the back side of the remote controller as the key display surface and the bottom side of the remote controller as the key layout top of the remote controller. Therefore, when the display terminal is controlled by the remote controller, the embodiment firstly obtains the position information of the remote controller, and then determines the key layout information of the remote controller according to the position information, so that the original key codes are converted according to the key layout information of the remote controller in the subsequent steps.
In one embodiment, the key layout information includes a key layout top and a key layout situation, and the step of determining the key layout information of the remote controller according to the location information in step S100 includes:
Step S110, determining the end part of the remote controller close to the display terminal according to the distance information, and determining the upward surface of the remote controller according to the front and back information;
and step S120, determining the end of the remote controller close to the display terminal as the key layout top, and determining the upward face of the remote controller as the key layout.
Specifically, the key layout information includes a key layout top and a key layout situation, where in the foregoing step, it is mentioned that the remote controller in this embodiment may display the remote controller key at 360 ° and uses an upward face as the key display surface and uses an end close to the display terminal as the key layout top, so when determining the key layout information of the remote controller according to the location information, this embodiment needs to determine, first, whether the end of the remote controller close to the display terminal is a top end or a bottom end according to the distance information, and determine, according to the front and back information, whether the upward face of the remote controller is a front or a back face, and then determine, as the key layout top, the end of the remote controller close to the display terminal, and determine, as the key layout situation, the upward face of the remote controller. For example, when it is determined that the end of the remote controller close to the display terminal is the top end and the face of the remote controller facing upward is the front face according to the distance information, it is determined that the remote controller keys are arranged with the front face of the remote controller as the display face and the top end of the remote controller as the key layout top.
In order to determine that the remote controller is close to the end of the display terminal, in this embodiment, four infrared transmitters are arranged on the remote controller and are respectively arranged at four corners of the remote controller, after the display terminal receives infrared signals emitted by the four infrared transmitters, distances from four corners of the remote controller to the receiving points can be determined according to the time that the four infrared signals reach the receiving points, and the end of the remote controller close to the display terminal can be determined according to the distances from the four corners of the remote controller to the receiving points. For example, still taking fig. 5 as an example, assuming that the side formed by the point (1) and the point (2) corresponds to the top end of the remote controller, and the side formed by the point (3) and the point (4) corresponds to the bottom end of the remote controller, when the distance values of the point (1), the point (2), the point (3) and the point (4) from the receiving point satisfy the point (1) > point (2) > point (3) > point (4), it is determined that the side formed by the point (3) and the point (4) is close to the display terminal, that is, the bottom end of the remote controller is close to the display terminal.
In one embodiment, step S100 further includes:
step S01, acquiring infrared signals emitted by the infrared emitters respectively;
and step S02, calibrating the remote controller according to the infrared signals emitted by the infrared emitters.
In order to realize that the remote controller displays remote controller keys according to key layout information, after the display terminal is awakened by a power key, the remote controller starts a calibration stage and sends a calibration starting command to the remote controller, the remote controller enters a calibration state after receiving the calibration command, infrared signals with different wavelengths are respectively transmitted to the display terminal through a plurality of infrared transmitters, the display terminal acquires the infrared signals respectively transmitted by the plurality of infrared transmitters, and the remote controller is calibrated according to the infrared signals respectively transmitted by the plurality of infrared transmitters.
In one embodiment, step S02 specifically includes:
step S021, determining a first three-dimensional plane position and a second three-dimensional plane position of the remote controller according to infrared signals emitted by the infrared emitters; the first three-dimensional plane position and the second three-dimensional plane position are determined by infrared signals emitted by a plurality of infrared emitters which are not completely identical;
and step S022, calibrating the remote controller according to the first three-dimensional plane position and the second three-dimensional plane position.
Because the wavelengths of the infrared signals emitted by different infrared emitters are different, after the display terminal obtains the infrared signals emitted by the plurality of infrared emitters, a first emission point set and a second emission point set can be determined according to the infrared signals emitted by the plurality of infrared emitters, wherein the first emission point set and the second emission point set are determined by the infrared signals emitted by the plurality of infrared emitters which are not completely identical, then a first three-dimensional plane position of the remote controller is determined according to each point in the first emission point set, a second three-dimensional plane position is determined according to each point in the second emission point set, and finally the remote controller is calibrated according to the first three-dimensional plane position and the second three-dimensional plane position. For example, still taking fig. 5 as an example, the number of infrared transmitters is set to 4, the display terminal determines that a first transmitting point set is a set formed by a point (1), a point (2) and a point (3) according to infrared signals transmitted by each of the plurality of infrared transmitters, a second transmitting point set is a set formed by a point (2), a point (3) and a point (4), a first three-dimensional plane position of the remote controller can be determined according to the point (1), the point (2) and the point (3), a second three-dimensional plane position of the remote controller can be determined according to the point (2), the point (3) and the point (4), and then the remote controller is calibrated according to the first three-dimensional plane position and the second three-dimensional plane position.
When the display terminal corrects the remote controller according to the first three-dimensional plane position and the second three-dimensional plane position, the first three-dimensional plane position and the second three-dimensional plane position are compared, when the first three-dimensional plane position and the second three-dimensional plane position are consistent, the correction is finished, when the first three-dimensional plane position and the second three-dimensional plane position are inconsistent, the display terminal continues to execute the steps of acquiring infrared signals emitted by the infrared emitters respectively, and correcting the remote controller according to the infrared signals emitted by the infrared emitters respectively until the first three-dimensional plane position and the second three-dimensional plane position are consistent. And after the display terminal still fails to calibrate the remote controller for a preset number of times, the remote controller displays the keys of the remote controller according to the default key layout.
In a specific embodiment, the remote controller is further provided with an acceleration sensor for sensing whether the three-dimensional plane of the remote controller is changed, and when the acceleration sensor senses that the three-dimensional plane of the remote controller is changed, the infrared transmitters on the remote controller continuously transmit infrared signals with different wavelengths to the display terminal, so that the display terminal calibrates the remote controller according to the infrared signals transmitted by the infrared transmitters.
Step 200, obtaining an original key code of the remote controller, converting the original key code according to the key layout information, and determining a target key code.
Since the remote controller in this embodiment can automatically adjust the key layout state of the remote controller key according to the position information of the remote controller, when the user uses the remote controller to control the display terminal, a problem that the key code sent by the remote controller is not matched with the key code that the user wants to press, for example, as shown in fig. 2 and 3, when the user presses the mute key in fig. 3, the key code actually sent by the remote controller to the display terminal is the key code corresponding to the magnifying glass, and if the display terminal control operation is executed according to the key code actually sent by the remote controller, a problem that the display terminal control operation that the user wants to execute is not matched with the display terminal control operation actually executed by the display terminal may occur.
Therefore, in this embodiment, when a user presses a certain remote control key on the remote control, the remote control sends an original key code corresponding to the remote control key to the display terminal, and after the display terminal obtains the original key code sent by the remote control, the display terminal converts the original key code according to the key layout information, so as to convert the original key code into a target key code. For example, still taking fig. 2 and 3 as an example, when the user presses the mute key in fig. 3, the original key code transmitted from the remote controller to the display terminal is actually the key code corresponding to the magnifying glass in fig. 2, and the display terminal needs to convert the key code corresponding to the magnifying glass into the key code corresponding to the mute key according to the key layout information, so as to execute the correct control operation of the display terminal.
In one embodiment, step S200 specifically includes:
step S210, determining the orientation code of the remote controller according to the key layout information;
and step S220, converting the original key codes according to the orientation codes, and determining target key codes.
In order to facilitate the display terminal to convert the original key codes under different key layouts, in this embodiment, the orientation codes corresponding to different key layout information are predefined, when the original key codes are converted according to the key layout information, the key layout information is first converted into the orientation codes, and then the original key codes are converted into the target key codes according to the orientation codes. For example, as shown in the following table 1, the azimuth code is composed of a first code value and a second code value, the first code value is determined by the top of the key layout, the first code value is 0 when the top of the key layout is the top of the remote controller, and the first code value is 1 when the top of the key layout is the bottom of the remote controller; the second code value is determined by the key layout, and is 0 when the key layout is the front side of the remote controller, and is 1 when the key layout is the back side of the remote controller. And so on, when the top of the key layout is the top of the remote controller and the key layout is the front of the remote controller, the azimuth code is 00; when the top of the key layout is the bottom end of the remote controller and the key layout is the front of the remote controller, the azimuth code is 10; when the top of the key layout is the top of the remote controller and the key layout is the back of the remote controller, the azimuth code is 01; when the top of the key layout is the bottom end of the remote controller and the key layout is the reverse side of the remote controller, the orientation code is 11.
Table 1 azimuth codes corresponding to different key layout information
| 0 right side up | 1 face down | |
| 0 top is close to display terminal | 00 | 01 |
| 1 bottom end is close to the display terminal | 10 | 11 |
In one embodiment, step S220 specifically includes:
step S221, obtaining an original position of the original key code in a preset mapping table, converting the original position according to the azimuth code, and determining a target position;
step S222, obtaining the key code corresponding to the target position, and determining the key code corresponding to the target position as the target key code.
In order to convert the original key code into the target key code, the display terminal is pre-stored with a function for converting the original key codeMapping tables, which are representable as a matrixFor example, when the remote controller key arrangement is 10×4, then mapping table a mn The size of (A) is A 20×8 . When the original key codes are converted according to the position codes, the original positions of the original key codes in a preset mapping table are firstly obtained, then the original positions are converted according to the position codes, the target positions corresponding to the target key codes are determined, finally the key codes corresponding to the target positions are obtained, and the key codes corresponding to the target positions are determined to be the target key codes.
In order to convert the original position, conversion rules corresponding to different azimuth codes are preset in this embodiment, and in the foregoing step, the azimuth code includes a first azimuth code 00, a second azimuth code 01, a third azimuth code 10, and a fourth azimuth code 11, so that the conversion rules corresponding to the azimuth code also correspond to the first conversion rule, the second conversion rule, the third conversion rule, and the fourth conversion rule, respectively.
