Below in conjunction with accompanying drawing, first the recording autocontrol method for mobile terminal according to the embodiment of the present invention is described.
With reference to figure 1, the recording autocontrol method for mobile terminal according to the embodiment of the present invention, comprises the steps:
Step S101, enters recording mode according to the user's of mobile terminal instruction.It is the sound-recording function that user starts mobile terminal.
Step S102, the voice messaging of recording user input, and start the sensor in mobile terminal.
Particularly, after user starts sound-recording function, typically, user can move to mobile terminal the place ahead of the mouth of oneself, to start recording, in example of the present invention, now, also need start sensor, the purposes of this sensor is for detecting in mobile terminal moving process, as mobile device moved to motion track and the moving direction in the process in the place ahead.For example sensor includes but not limited to: one or more in gyroscope, gravity sensor, acceleration transducer, need to illustrate, as long as other sensor that can detect the motion track of mobile terminal and moving direction or pick-up unit all can, embodiments of the invention are to this not restriction.
Step S103, detects motion track and the moving direction of mobile terminal by sensor.As shown in Figure 2, according to user, use mobile terminal 210 to carry out the custom of Recording Process, conventionally when user uses mobile terminal 210 to record, mobile terminal 210 is moved to oneself mouth before, as the position X at mobile terminal place in Fig. 2; And when finishing recording, conventionally mobile terminal 210 is moved to position Y as shown in Figure 2.And user is by mobile terminal 210 from the X moving process of Y-direction position, position, and moving direction is for making progress, otherwise moving direction is downward.Again in conjunction with Fig. 2, according to the custom analysis of user's Recording Process, the motion track of its mobile terminal 210 is around user's elbow joint 200, to form the track of motion, the motion track shown in the dotted line between position X and position Y as shown in Figure 2, further, position X is positioned on plane A, and position Y may have a plurality of points, as shown in Figure 2, be roughly positioned on plane B, thus, movement locus can be for a plurality of.
To sum up analyze, sensor is motion track and the moving direction of S31 to S36 detection mobile terminal as follows, and step S31 is as follows to step S36:
Step S31, judges whether the acceleration of mobile terminal 210 is greater than first threshold.Particularly, by sensor, detect the acceleration of mobile terminal 210 in multiple directions, the acceleration along X, Y and Z direction in the space forming as the X-axis in space, Y-axis and Z axis forms the acceleration of mobile terminal 210 jointly.In when recording, mobile terminal 210 is positioned at position X and acceleration is less or close to 0.Therefore, this first threshold can be set to 0 or relatively little value, and this first threshold can be determined by empirical value.
Step S32, if acceleration is greater than first threshold, the reference position using the current location of mobile terminal 210 as mobile terminal.If the acceleration of judgement mobile terminal 210 is greater than above-mentioned first threshold, think that mobile terminal 210 has moved.
Step S33, the acceleration information in multiple directions in record move terminal 210 moving process and direction of motion information.When step S32 judgement mobile terminal moves, by sensor record as the direction of motion information of the acceleration information of the mobile terminal 210 of X, Y and Z direction and mobile terminal 210 (as the direction of motion information along all directions).
Step S34, judges whether the acceleration of mobile terminal 210 is less than Second Threshold.In mobile terminal 210 moving process, the acceleration by all directions of judgement mobile terminal 210 obtain along the acceleration on movement locus, and judge that this acceleration is less than Second Threshold, this Second Threshold is 0 or less, similarly, also can be determined by empirical value.
Step S35, if acceleration is less than Second Threshold, the end position using the current location of mobile terminal 210 as mobile terminal 210.As a concrete example, as shown in Figure 2, can think that now mobile terminal 210, in position Y, thinks that user finishes recording.
Step S36, according to reference position and end position, and between reference position and end position, acceleration information and the direction of motion information of each motor point in multiple directions is calculated motion track.In this example, can by a plurality of values obtained above, obtain according to existing movement locus method for tracing the movement locus of mobile terminal 210.Its computation process belongs to prior art, does not repeat.
Step S104, judges according to motion track and moving direction whether user has the intention that finishes recording.For example, the movement locus that the position habit of when movement locus of the mobile terminal 210 obtaining by above-mentioned steps S103 and user conventionally record and finish to record, mobile terminal 210 being placed produces compares, if it is similar that movement locus equally lives, can judge whether user has the intention that finishes recording.Particularly:
Motion track storehouse is set up in action while finishing recording mode according to user, if the motion track that the sensor of mobile terminal detects meets motion track storehouse, and moving direction is downward, judges that user has the intention that finishes recording.In conjunction with Fig. 2, the action while finishing recording mode as user is generally mobile terminal 210 is moved into place to the position Y in surface level B from position X again.And according to an above-mentioned embodiment, position Y is a plurality of points, therefore can obtain a plurality of motion tracks, and form motion track storehouse by a plurality of motion tracks, the motor habit when foundation in this track storehouse finishes recording mode according to user obtains, as normally moved to position Y from position X along the arc dotted line between position X and position Y centered by elbow joint 200.
Motion track and direction that whether the movement locus of the mobile terminal 210 that therefore, determining step S103 obtains meets in above-mentioned motion track storehouse are roughly downward.
Step S105, if judgement user has the intention that finishes recording, closes recording mode.If motion track and direction that the movement locus of the mobile terminal 210 that determining step S103 obtains meets in above-mentioned motion track storehouse are roughly downward, think that user has the intention that finishes recording, now mobile terminal 210 is closed recording mode automatically, finishes recording.
