In order to solve the problems that an entity key is easy to damage and inconvenient to operate when a cursor is controlled to move through the entity key on a remote controller, the embodiment of the invention designs the following technical scheme: the cursor movement of the second terminal is controlled based on the acceleration sensor in the first terminal, namely, the user can control the cursor movement of the second terminal by controlling the gesture of the second terminal, so that the operation of controlling the cursor movement by the entity keys on the touch remote controller is omitted, the operation is more convenient, and the problem that the cursor control is affected due to the fact that the entity keys are easy to damage is also avoided.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a cursor control method according to the present invention is shown, and the method may be applied to a first terminal provided with an acceleration sensor, where the first terminal is a mobile terminal, such as a mobile phone.
The method specifically comprises the following steps:
step 101: and under the condition that the first terminal is in the remote controller mode, respectively acquiring the numerical value of the acceleration sensor on the first coordinate axis and the numerical value of the acceleration sensor on the second coordinate axis.
In the embodiment of the invention, the working mode of the first terminal at least comprises a remote controller mode. The first terminal may control the cursor movement of the second terminal based on the value of the acceleration sensor on the first coordinate axis and the value on the second coordinate axis in the case of being in the remote controller mode.
The first coordinate axis and the second coordinate axis are two coordinate axes in a coordinate system corresponding to the acceleration sensor. Generally, the acceleration sensor includes three axes of sensitivity, and the three axes of sensitivity are perpendicular to each other, so the coordinate system corresponding to the acceleration sensor may be a three-dimensional coordinate system, and each axis of sensitivity corresponds to a coordinate axis. The screen of the first terminal is taken as a reference object, and for the acceleration sensor arranged in the first terminal, one sensitive axis is generally perpendicular to the screen of the first terminal, the coordinate axis corresponding to the sensitive axis is generally denoted as a z axis, and the other two sensitive axes are parallel to the screen of the first terminal and are generally respectively denoted as an x axis and a y axis.
Since the movement space of the cursor is a two-dimensional space, the movement of the cursor may be controlled by taking the values of two coordinate axes in the coordinate system corresponding to the acceleration sensor. The first coordinate axis may be an x-axis, the second coordinate axis may be a y-axis, and a coordinate system constructed between the x-axis and the y-axis may be as shown in fig. 2. On the basis of the coordinate system shown in fig. 2, when the first terminal is tilted to the left, the value on the x-axis is a positive value; when the first terminal is inclined rightwards, the value on the x-axis is a negative value; when the first terminal tilts upwards, the y axis is a positive value; the y-axis is negative when the first terminal is tilted downward. It should be noted that the foregoing is based on the user holding the first terminal in the forward direction, i.e. the screen of the first terminal is facing upwards and the top and bottom of the first terminal are positioned in the forward direction with respect to the user.
Step 102: and determining the target key value according to the numerical value of the acceleration sensor on the first coordinate axis and the numerical value of the acceleration sensor on the second coordinate axis.
In the embodiment of the invention, after the value of the acceleration sensor on the first coordinate axis and the value of the acceleration sensor on the second coordinate axis are obtained, the target key value can be determined according to the obtained values of the coordinate axes. The target key value is a key value corresponding to an upward direction key, a key value corresponding to a downward direction key, a key value corresponding to a leftward direction key or a key value corresponding to a rightward direction key of the remote controller. For example, the key values corresponding to the up, down, left and right direction keys of the remote controller are 19, 20, 21 and 22 respectively, and the target key value is one of the four key values.
In the embodiment of the invention, the corresponding relation between the positive and negative values on the coordinate axis and the direction key can be established in advance. For example, a positive number on a first axis may be set to correspond to a left direction key, a negative number to correspond to a right direction key, and a positive number on a second axis may be set to correspond to an up direction key, and a negative number to correspond to a down direction key. Of course, other arrangement modes are also possible, and the specific situation can be set according to actual requirements.
Step 103: and controlling the cursor of the second terminal to move according to the direction corresponding to the target key value.
After the target key value is determined, the first terminal can control the cursor of the second terminal to move according to the direction corresponding to the target key value. For example, if the direction corresponding to the target key value is rightward, the cursor is controlled to move rightward; for another example, if the direction corresponding to the target key value is downward, the cursor is controlled to move downward.
The first terminal and the second terminal may be connected by communication (such as bluetooth), and the cursor control signal (such as a target key value) is sent and received through the communication. Or the first terminal is provided with an infrared emitter, the second terminal is provided with an infrared receiver, the first terminal sends a cursor control signal to the second terminal through the infrared emitter, and the second terminal receives the cursor control signal through the infrared receiver. It will be appreciated that other communication means may be used to implement the transmission of the cursor control signal between the first terminal and the second terminal. The first terminal can send the target key value to the second terminal, so that the second terminal controls the cursor to move according to the target key value. The second terminal may be a video networking terminal, a television or other terminal devices requiring a remote controller to control cursor movement.
In the embodiment of the invention, the cursor movement of the second terminal is controlled based on the acceleration sensor in the first terminal, namely, the user can control the cursor movement of the second terminal by controlling the gesture of the second terminal, so that the operation of controlling the cursor movement by touching the entity keys on the remote controller is omitted, the operation is more convenient, and the problem that the cursor control is influenced because the entity keys are easy to damage is also avoided. In addition, under the condition that the first terminal is a mobile phone, the mobile phone is almost an indispensable device in daily life of people, and the mobile phone body is light and portable, so that the mobile phone is utilized to control the cursor to move, and the utilization rate of the mobile phone can be improved besides being independent of a remote controller.
As an alternative embodiment, in an embodiment of the present invention, the acceleration sensor may be a gravitational acceleration sensor.
In the case where the acceleration sensor is a gravitational acceleration sensor and the first coordinate axis is an x axis and the second coordinate axis is a y axis, a coordinate system constructed between the x and y axes may be as shown in fig. 3, and an absolute value of a maximum value of the x and y axes may be set to 9.81 (i.e., a value corresponding to gravitational acceleration).
As an alternative embodiment, step 102: determining the target key value according to the value of the acceleration sensor on the first coordinate axis and the value of the acceleration sensor on the second coordinate axis may include:
determining a coordinate axis with an absolute value of a numerical value larger than or equal to a first preset numerical value in the first coordinate axis and the second coordinate axis as a target coordinate axis; determining the key value of the corresponding direction key according to the positive and negative of the numerical value of the target coordinate axis; and determining the key value of the direction key corresponding to the positive and negative of the numerical value of the target coordinate axis as the target key value.
When the user operates the first terminal, the absolute vertical direction or the absolute horizontal direction is generally not used for moving, for example, taking the coordinate system shown in fig. 2 as an example, when the user controls the first terminal to move upwards, the value on the y axis is increased, and the value on the x axis is also changed to a certain extent.
The first preset value is greater than 0, and a specific value can be set according to actual requirements. For example, when the acceleration sensor is a gravitational acceleration sensor and the coordinate system constructed by the first coordinate axis and the second coordinate axis is as shown in fig. 3, the first preset value may be set to 5.
In the embodiment of the invention, a coordinate axis with an absolute value larger than or equal to a first preset value can be determined as a target coordinate axis, the movement of a cursor is controlled according to the value of the target coordinate axis, specifically, the key value of a corresponding direction key is determined according to the positive and negative of the value of the target coordinate axis, and the key value of the direction key corresponding to the positive and negative of the value of the target coordinate axis is determined as a target key value. For example, the target coordinate axis is the x axis shown in fig. 2, the value of the acceleration sensor on the x axis is-6, then according to the preset correspondence between the positive and negative values on the coordinate axis and the direction key, the right direction key of the remote controller corresponding to the negative value on the x axis can be determined, and according to the key value corresponding to the right direction key being 22, the key value of the direction key corresponding to the positive and negative of the value of the target coordinate axis can be determined to be 22, that is, the target key value is 22.
It should be noted that, when the absolute values of the first coordinate axis and the second coordinate axis are both greater than or equal to the first preset value, and the values of the first coordinate axis and the second coordinate axis are different, the coordinate axis whose value reaches the first preset value may be determined as the target coordinate axis. When the absolute values of the first coordinate axis and the second coordinate axis are both greater than or equal to the first preset value, and the values of the first coordinate axis and the second coordinate axis are the same, the preset coordinate axis can be determined as the target coordinate axis. The preset coordinate axis is a first coordinate axis or a second coordinate axis, and the preset coordinate axis can be default of the system or set by a user.
As an alternative embodiment, step 103: the controlling the cursor of the second terminal to move according to the direction corresponding to the target key value may include:
and controlling the cursor of the second terminal to move once according to the direction corresponding to the target key value under the condition that the absolute value of the target coordinate axis is changed from the first preset value to be smaller than or equal to the second preset value within the first preset time.
Since the acceleration sensor is very sensitive, the minute actions may cause the numerical values on the first coordinate axis and the second coordinate axis to change, that is, the numerical values may change very rapidly and may change 10 times within 1 second, so the sensitivity of the acceleration sensor is relieved by setting the second preset numerical value, and whether the first terminal is restored to the initial position is judged according to the second preset numerical value. In this case, the movement distance of the cursor is generally one step, which is the distance the cursor moves from the current position to the nearest position to which it can move.
The second preset value is greater than 0 and smaller than the first preset value, and a specific value can be set according to actual requirements. For example, when the acceleration sensor is a gravitational acceleration sensor and the coordinate system constructed by the first coordinate axis and the second coordinate axis is as shown in fig. 3, the first preset value may be set to 2.
The first preset duration is a duration longer than 0, and the specific value can be set according to actual requirements.
In order to better understand the above, a further explanation is given below with an example. This example is illustrated by way of example in the coordinate system shown in fig. 3.
First, in the embodiment of the present invention, a variable KeyCode may be created in advance.
Secondly, the first terminal can monitor the numerical value change of the x axis and the y axis of the gravity acceleration sensor in real time or at regular time under the condition of being in a remote controller mode. Assuming that the first terminal detects that the absolute value of the value on the y-axis exceeds 5 and the value on the y-axis is 6, the key code can be assigned as the key value of the corresponding direction key, assuming that the user performs the upward tilting operation on the first terminal. For example, a positive value on the y-axis corresponds to an up arrow key, while an up arrow key value of 19 assigns KeyCode to 19. And then, the first terminal continues to monitor the change of the values of the x axis and the y axis of the gravity acceleration sensor, when the absolute value of the value on the y axis is smaller than 2, the user is considered to operate the first terminal to enable the posture of the first terminal to be restored to the initial state, the first terminal can send the value of the Key code to the second terminal, so that the second terminal can simulate the key operation of an upward direction key of the remote controller, the cursor is controlled to move upwards for one step length, then the Key code is emptied, and the next operation of the user is waited. Alternatively, the second terminal may simulate a key operation of an upward direction key of the remote controller through an Android (i.e., android) program.
As an alternative embodiment, step 103: the controlling the cursor of the second terminal to move according to the direction corresponding to the target key value may include:
after the absolute value of the numerical value of the target coordinate axis reaches the maximum value and lasts for a second preset duration, detecting whether the absolute value of the numerical value of the target coordinate axis is kept at the maximum value or not every third preset duration; and under the condition that the absolute value of the numerical value of the target coordinate axis is kept at the maximum value, controlling the cursor of the second terminal to move once according to the direction corresponding to the target key value.
Sometimes, in order to make the cursor reach the preset position quickly, the user may continuously move the cursor until the preset position is reached by pressing the direction key on the remote controller for a long time. In this regard, the embodiment of the present invention provides a manner of implementing the above process based on the gesture of the first terminal, that is: after the first terminal detects that the absolute value of the numerical value of the target coordinate axis reaches the maximum value and continues for the second preset duration, it detects whether the absolute value of the numerical value of the target coordinate axis is maintained at the maximum value every third preset duration (for example, 500 milliseconds).
And if the absolute value of the numerical value of the target coordinate axis is maintained at the maximum value, controlling the cursor to move once according to the direction corresponding to the target key value, and the like until the absolute value of the numerical value of the target coordinate axis is detected to be no longer maintained at the maximum value or the cursor cannot move continuously according to the direction corresponding to the target key value.
If it is detected that the absolute value of the numerical value of the target coordinate axis is not maintained at the maximum value, the cursor movement is controlled according to the above manner, namely: and controlling the cursor of the second terminal to move according to the direction corresponding to the target key value under the condition that the absolute value of the target coordinate axis is changed from the first preset value to be smaller than or equal to the second preset value within the first preset time period.
Wherein the first preset time period is longer than the second preset time period. The second preset time length and the third preset time length are both time lengths greater than 0, and specific numerical values can be set according to actual requirements. Typically, the second preset time period is longer than the third preset time period.
Wherein the first preset value is less than the maximum value.
In summary, in the embodiment of the present invention, the cursor movement of the second terminal is controlled based on the acceleration sensor in the first terminal, that is, the user can control the cursor movement of the second terminal by controlling the gesture of the second terminal, so that the operation of controlling the cursor movement by touching the physical key on the remote controller is omitted, the operation is more convenient, and the problem that the cursor control is affected due to the fact that the physical key is easy to damage is also avoided.
