In order to more clearly explain the playback control method of the multimedia file provided by the foregoing embodiment, in conjunction with the content of the foregoing embodiment, a playback control method for a multimedia file is described in detail by using the following second embodiment as an example. Example 2. Embodiment 2

The present embodiment provides a method for controlling playback of a multimedia file. For convenience of description, the method provided in this embodiment is exemplified in detail by taking the mobile terminal as a mobile phone with the operating system as the Android system as an example. Referring to FIG. 2, the method process provided by this embodiment includes the following steps.

In step 201, the acceleration values measured by the sensors in the mobile phone in various directions of the space rectangular coordinate system are obtained. For this step, the sensor is not specifically limited in this embodiment. For example, the sensor is a gyroscope in a cell phone, or another sensor in a cell phone that can measure acceleration.

In addition, this embodiment does not limit the specific manner of detection. For example, a monitoring module can be registered in the system platform of the Android system, and the monitoring module can obtain the acceleration value measured by the sensor in the mobile phone in all directions of the space rectangular coordinate system.

Wherein, the spatial Cartesian coordinate system has x, y, and z directions, X is the horizontal axis direction, y is the vertical axis direction, and y is the number axis direction.

In step 202, the current state of the mobile phone and the acceleration of the space setting vector are determined according to the acceleration values measured by the sensor in various directions of the spatial rectangular coordinate system. For this step, the acceleration average value on the spatial setting vector is determined according to the acceleration value measured by the sensor in each direction of the space rectangular coordinate system, and according to the acceleration average value, the current state of the mobile phone can be determined. Here, the space setting vector corresponding to the acceleration average value may be the same as or different from the space setting vector corresponding to the change in the acceleration.

For convenience of description, taking the state of the mobile phone, including the handheld state and the flat state, as an example, since the average value of the acceleration of the handheld state of the mobile phone is generally greater than the average value of the acceleration of the mobile phone in the flat state, the first threshold is set, and the first threshold is set. The minimum value of the acceleration in the hand-held state. If the average value of the acceleration is less than the first threshold, it is determined that the current state of the terminal is a flat state; if the average value of the acceleration is not less than the first threshold, it is determined that the current state of the terminal is a handheld state.

The first threshold is determined according to the empirical value. This embodiment does not limit the determining manner and specific size of the first threshold. Of course, the state in which the mobile phone is located may have other states besides the above-mentioned hand-held state and the flat state. This embodiment does not limit the specific state in which the mobile phone is currently located. In addition, the method for determining the current state of the mobile phone according to the acceleration value measured by the sensor in each direction of the space rectangular coordinate system may be other methods besides the above method, and the present embodiment is also not based on the sensor in the space rectangular coordinate system. The specific determination method for determining the current state of the mobile phone by the acceleration value measured in the direction is limited.

In addition, since the acceleration values measured by the sensors in all directions of the space rectangular coordinate system are vectors, a spatial setting vector can be determined according to the acceleration values measured by the sensors in various directions of the spatial rectangular coordinate system. The vector may be any vector in the space vector, which is not specifically limited in this embodiment. By counting the acceleration values of the spatial rectangular coordinate system detected by the sensor in a certain period of time, the acceleration variation on the spatial setting vector in the time period can also be obtained.

In step 203, it is determined whether the change of the acceleration conforms to the mode feature of the double-click event according to the current state of the mobile phone and the change of the acceleration on the space setting vector. If the change of the acceleration conforms to the mode feature of the double-click event, step 204 is performed. If the change in acceleration does not match the pattern characteristics of the double-click event, the process ends.

For this step, the specific judgment manner of determining whether the change of the acceleration conforms to the mode feature of the double-click event according to the current state of the mobile phone and the change of the acceleration on the space setting vector may be adopted but not limited to the following two modes.

The first way: If the current state of the mobile phone is in a flat state, it is determined whether the change of the acceleration on the spatial setting vector is the two peaks in the first numerical range, and whether the interval between the two peaks is less than the first A preset time.

For the first mode, if the change of the acceleration on the space setting vector is the occurrence of two peaks in the first numerical range, and the interval between the two peaks is less than the first preset time, it is determined that the change of the acceleration conforms to the double-click event. Mode characteristic; if the acceleration of the space setting vector changes to two peaks within the first value range, or although the acceleration of the space setting vector changes to two peaks within the first value range However, if the interval between the two peaks is not less than the first preset time, it is judged that the change in the acceleration does not conform to the mode feature of the double-click event.

In addition, in this embodiment, the specific determination method for determining whether the change of the acceleration on the spatial setting vector is the two peaks in the first numerical range and the interval between the two peaks is less than the first preset time is not limited. For example, according to the curve of the acceleration on the space setting vector, it is determined whether the curve is twice within the first numerical range Peak, and whether the interval between the two peaks is less than the first preset time. For example, the first value range may be lm/s2 (meters per square second) -2 m/s2, and the first preset time may be any value less than 200 ms (milliseconds). Certainly, the first numerical range and the first preset time may also be other values. In this embodiment, the specific value of the first numerical range and the first preset time is not limited.

The second mode: if the current state of the terminal is the handheld state, it is determined whether the change of the acceleration on the spatial setting vector is the two peaks in the second numerical range, and whether the interval between the two peaks is less than the second Preset time.

For the second mode, if the change of the acceleration on the space setting vector is the occurrence of two peaks in the second numerical range, and the interval between the two peaks is less than the second preset time, it is determined that the change of the acceleration conforms to the double-click event. Mode characteristic; if the change in acceleration on the space setting vector is such that two peaks in the second value range do not occur, or although the change in acceleration in the space setting vector occurs in two peaks in the second value range, If the interval between the two peaks is not less than the second preset time, it is determined that the change in the acceleration does not conform to the mode feature of the double-click event.

In addition, the present embodiment does not define whether the change of the acceleration on the spatial setting vector is the occurrence of two peaks in the second numerical range, and whether the interval time of the two peaks is less than the second predetermined time. For example, according to the curve of the acceleration on the space setting vector, it is determined whether the curve is the two peaks in the second numerical range, and the interval between the two peaks is less than the second preset time. For example, the second value range is 2 m/s 2-3 m/s 2 and the second preset time is any value between 300 m _{S and} 500 ms. Certainly, the second value range and the second preset time may also be other values. This embodiment does not limit the specific size of the second value range and the second preset time.

It should be noted that the mode feature of the double-click event has two peaks in the first value range except the above, and the interval between the two peaks is less than the first preset time, or two peaks in the second value range appear, and The interval between the two peaks is smaller than the second preset time, and may be other features. The mode feature of the double-click event is not specifically limited in this embodiment.

In step 204, playback control is performed on the multimedia file.

For this step, the state of the multimedia file is determined, and the playback control is performed according to the state of the multimedia file. If the multimedia file is in the playback state, the multimedia file is paused. Or, if the multimedia file is in the paused state, the multimedia file is played.

In addition, the state in which the multimedia file is located may be other states. This embodiment does not limit the specific state of the multimedia file. In addition, when the multimedia file is in a state other than the playing state and the suspended state, other playback control operations are performed according to the specific state in which the multimedia file is located. This embodiment does not limit the specific type of the playback control, and the embodiment does not apply to the multimedia. The specific correspondence between the status and the playback control is limited.

In addition, this embodiment does not limit the specific determination rule of the state in which the multimedia file is located, including but not limited to: Since the playback controller itself records the state of the currently played multimedia file, according to the playback controller itself A record of the state of the currently playing multimedia file determines the state of the multimedia file.

It should be noted that, in this embodiment, the playback control method of the multimedia file provided in this embodiment is exemplified by taking the mobile terminal as the mobile phone as an example. In specific implementation, the terminal that plays multimedia can also be used in addition to the mobile phone. In the case of a tablet computer or other device, this embodiment does not limit the specific product form of the terminal that plays multimedia. In addition, the operating system used by the terminal playing the multimedia may be a Saipan system or other system in addition to the Android system. This embodiment does not limit the operating system used by the terminal playing the multimedia.

In the method provided by the embodiment, the double-click operation performed by the user may be reflected by the acceleration of the terminal. After the user performs the double-click operation, the acceleration of the terminal is detected to determine whether the change of the acceleration conforms to the mode feature of the double-click event, and according to the judgment result. The multimedia file is played and controlled, and the multimedia file can be played and controlled according to the double-click operation, thereby improving the playback control speed of the multimedia file under the premise of simplifying the user operation, and reducing the chance of accidentally touching other function keys, thereby increasing the correct operation probability.
