detailed description

In order to understand the features and technical contents of the embodiments of the present application in more detail, the implementation of the embodiments of the present application is described in detail below in conjunction with the drawings. The accompanying drawings are for reference only and are not intended to limit the embodiments of the present application.

FIG. 2 is a schematic flowchart of a method for adjusting a barrage according to an embodiment of the present application. As shown in FIG. 2, the method for adjusting a barrage includes the following steps:

Step 201: Obtain the angular velocity or acceleration vector generated by the terminal motion.

The terminal here may be a mobile terminal. In this embodiment, a mobile phone is used as an example for description. A mobile phone gyroscope (also called an angular velocity sensor) and an accelerometer are built into the mobile phone. The mobile phone gyroscope measures the rotational angular velocity of the mobile phone when it is deflected or tilted. , The accelerometer measures the acceleration generated during the movement of the mobile phone.

Specifically, taking a three-axis gyroscope applied to a mobile phone terminal as an example, it is used to measure the rotation rate on the X, Y, and Z axes, and the unit is rad / s. Taking a mobile phone as an example, lay the mobile phone flat on the desktop with the screen facing up, and rotate the mobile phone counterclockwise to obtain the rotation rate of the Z axis. Each channel of the gyroscope detects the rotation of one axis. In the actual detection, the rotation rate of the three axes is obtained, and then the actual angular velocity vector is obtained. m / s ² , by measuring the acceleration of gravity on three axes, the acceleration vector generated by the actual mobile phone movement can be obtained.

In practical applications, the user generates the angular velocity or acceleration vector by shaking or tilting the operation. Here, you can set the angular velocity or acceleration threshold for shaking detection. When the acceleration or angular velocity generated by the actual movement of the terminal exceeds the threshold, the movement state is determined. For shaking, proceed to step 202.

Step 202: Adjust the scroll speed or area position of the barrage displayed in the terminal according to the angular velocity or acceleration vector.

It is worth noting that the scrolling speed of the barrage and the area position of the barrage are completely different concepts. The barrage is a kind of display information scrolling in a predetermined display area. When adjusting the scrolling speed, the adjustment of the scrolling speed of the barrage in the predetermined display area is realized, thereby adjusting the display time of a single barrage. The area position of the barrage is adjusted, but when the scrolling speed is kept stable, the position of the area of the barrage is changed, and the position area is determined by the angular velocity or acceleration vector of the terminal. The display position of the barrage is associated with the posture of the terminal after the movement, so that the position of the area displayed by the barrage matches the viewing line of the user, thereby ensuring the viewing effect of the barrage and improving the user's experience of viewing the barrage. Therefore, the adjustment of the scrolling speed of the barrage and the area of the barrage are two different dimensions.

At the same time, users can control the position of the area displayed by the barrage through the mobile terminal. Compared with the operation of a small area of the barrage to control the position of the area displayed by the barrage, user operations are simplified and improved. The user's operating experience.

There are two kinds of adjustment basis here, one is the direction of the vector, and the other is the size of the vector, which respectively correspond to the direction and amplitude of the user's shaking in specific practical applications: the user can change the angular velocity or acceleration of the terminal by shaking the terminal The direction of the shaking is the same as the direction of the angular velocity or acceleration generated by the terminal, so as to adjust the position or scrolling speed of the barrage display area.

In an embodiment, the adjusting the scrolling speed or area position of the barrage displayed on the terminal according to the angular velocity or acceleration vector includes: when the direction of the angular velocity or acceleration vector and the first preset direction If they are the same, the scroll speed of the barrage is reduced; when the direction of the angular velocity or acceleration vector is opposite to the first preset direction, the scroll speed of the barrage is increased. Macroscopically, that is, the direction in which the terminal shakes is the same as the preset direction, the scrolling speed of the barrage is reduced; when the terminal shakes in the direction opposite to the preset direction, the scrolling speed of the barrage is increased. For example, if the first preset direction is set to be horizontal to the left, the somatosensory operation of shaking to the left corresponds to slowing down the scrolling speed of the barrage, and the somatosensory operation of shaking to the right corresponds to the realization of increasing the playback speed of the barrage.

In one embodiment, the adjusting the scrolling speed or area position of the barrage displayed on the terminal according to the angular velocity or acceleration vector further includes: when the direction of the angular velocity or acceleration vector and the second preset If the directions are the same, the position of the area is moved up; when the direction of the angular velocity or acceleration vector is opposite to the second preset direction, the position of the area is moved down. For macro operations, that is, the direction of the terminal shaking is the same as the preset direction, the position of the area of the barrage displayed in the terminal is moved up; when the shaking direction is opposite to the preset direction, the position of the area of the barrage displayed in the terminal is lowered shift. For example, if the second preset direction is set horizontally to the left, then the somatosensory operation of shaking to the left corresponds to the movement of the area of the barrage up, while the somatosensory operation of shaking to the right corresponds to the movement of the area of the barrage down. The effect of moving the display area down is shown in Figure 3.

In one embodiment, the adjusting the scroll speed or area position of the barrage displayed in the terminal according to the angular velocity or acceleration vector further includes: determining the elasticity according to the modulus of the angular velocity or acceleration vector The magnitude of the increase or decrease of the scrolling speed of the screen; the magnitude of the upward or downward movement of the area position is determined according to the modulus of the angular velocity or acceleration vector. In terms of macro operation, the strength of controlling the barrage adjustment by shaking the terminal can be quantified. Specifically, the amplitude of the barrage adjustment corresponding to the modulus of the terminal angular velocity or acceleration vector can be preset, for example: the acceleration magnitude generated when the terminal motion generates When it reaches 12m / s ² , the corresponding playback speed increases or decreases by one unit. When the terminal movement produces an acceleration of 18m / s ² , the corresponding playback speed increases or decreases by two units; the preset when the terminal movement produces an acceleration of 12m / s ² , The position of the corresponding barrage display area moves up or down by one unit. When the terminal motion produces an acceleration of 18m / s ² , the position of the corresponding barrage display area moves up or down by two units.

In one embodiment, according to a preset time, according to the detected number and direction of shaking of the terminal, the scrolling speed or area position of the barrage displayed on the terminal is adjusted. The following uses the area position adjustment as an example. The barrage control parameter corresponding to the control command for controlling the display of the barrage upward movement is 1 and the barrage control parameter corresponding to the control command for moving the barrage display position downward is -1. That is, every time the barrage display position control instruction is received, that is, the display position of the barrage on the screen is moved by 1 unit according to the direction corresponding to the barrage display position control instruction. Within a preset time of 2s, the mobile phone recognizes that the user has performed a somatosensory operation of shaking the phone up three times, and a somatosensory operation of shaking the phone twice down. Based on the above settings, the control commands corresponding to the five somatosensory operations can be determined The control parameter is (3 × 1) + [2 × (-1)] = 1, that is, after receiving the five control commands triggered by the five somatosensory operations, the mobile phone will move the barrage upward by one unit in the screen display area .

In one embodiment, the deflection angle and the deflection direction generated by the terminal are acquired; according to the deflection angle and the deflection direction, the scrolling speed or area position of the barrage displayed in the terminal is adjusted. Taking a mobile phone terminal as an example, the deflection angle and deflection direction of the terminal can be obtained by the gyroscope built in the mobile phone. The gyro does not directly measure the deflection angle, but the current terminal deflection angle can be obtained through calculation processing. According to the obtained deflection angle and The deflection direction adjusts the scrolling speed or area position of the barrage displayed in the terminal. The adjustment method is similar to the method according to the angular velocity or acceleration vector in the foregoing embodiment. In practical applications, the user can change the deflection angle of the terminal by tilting the terminal And the direction of deflection to adjust the position or scrolling speed of the barrage display area.

In one embodiment, the adjusting the scroll speed or area position of the barrage displayed in the terminal according to the deflection angle and the deflection direction includes: when the direction of the deflection direction is the same as the first preset direction , The scroll speed of the barrage is reduced; when the deflection direction is opposite to the first preset direction, the scroll speed of the barrage is increased. For example, if the first preset direction is set to tilt to the left, the somatosensory operation to tilt to the left corresponds to slowing down the scrolling speed of the barrage, and the somatosensory operation to tilt to the right corresponds to realizing to increase the playback speed of the barrage.

In an embodiment, the adjusting the scrolling speed or area position of the barrage displayed in the terminal according to the deflection angle and the deflection direction further includes: when the direction of the deflection direction and the second preset direction If it is the same, the position of the area is moved up; when the deflection direction is opposite to the second preset direction, the position of the area is moved down. For example, if the first preset direction is set to tilt to the left, the somatosensory operation tilted to the left corresponds to realizing the upward movement of the area of the barrage, and the somatosensory operation tilted to the right corresponds to realizing the downward movement of the area of the barrage.

In one embodiment, the adjusting the scrolling speed or area position of the barrage displayed in the terminal according to the deflection angle and the deflection direction further includes: determining the scrolling of the barrage according to the deflection angle The magnitude of the increase or decrease of the speed; according to the deflection angle, the magnitude of the upward or downward movement of the area position is determined. For macro operations, you can quantify the intensity of controlling the barrage adjustment by shaking the terminal. For example: you can preset the tilt angle to increase by 5 degrees, and the playback speed of the barrage will respond to increase or decrease by 1 unit. Set the tilt to the right to slow down the playback speed of the barrage; when it is determined that the user's somatosensory operation on the phone is to tilt the phone to the right and the tilt angle is 10 degrees, you can determine that the control command corresponding to the somatosensory operation is to slow down the barrage Play speed, and the control specifies that the corresponding control parameter is 2 units, that is, the mobile phone reduces the current scroll speed of the barrage by 2 units.
