Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
The embodiment of the present invention provides a kind of terminal and its method for realizing reading posture detection, is passed using 3-axis acceleration
Sensor carries out the detection of user's reading posture, and is detecting reading posture to the detected value of specific direction gravity acceleration value
For mistake posture (such as recumbency sees the mobile phone) when, prompting can be sent, to correct the improper reading habits of user, reach eyeshield
Purpose, especially for child user, good supervisory role can be played, improve the usage experience of user.Lead to below
Several specific embodiments are crossed the implementation process of the present invention is described in detail.
In the first embodiment of the present invention, a kind of method that terminal realizes reading posture detection, the present embodiment institute are provided
It states and 3-axis acceleration sensor is equipped in terminal, the Z axis of the 3-axis acceleration sensor is perpendicular to terminal screen, X-axis and Y-axis
The plane of formation is parallel to terminal screen.Specifically, as shown in Figure 1, the present embodiment the described method includes：
Step S101 obtains the gravity acceleration value of the Z axis forward direction of 3-axis acceleration sensor acquisition；
In one particular embodiment of the present invention, the Z axis forward direction of 3-axis acceleration sensor refers to：User oriented one side
Direction for details, reference can be made to Fig. 2.Certainly, Z axis forward direction will be set to backwards to the direction of user one side and nor affects on implementation of the invention.
Step S102 according to default gravity acceleration value and the correspondence of reading posture, determines to obtain described
The corresponding reading posture of gravity acceleration value.
In the embodiment of the present invention, for terminal under different use states, the Z axis that 3-axis acceleration sensor collects is positive
Gravity acceleration value it is different, for example：
Assuming that three reference axis of 3-axis acceleration sensor are as shown in Fig. 2, i.e.：X-axis and Y-axis are parallel to where terminal
Plane, X-axis are the widths of terminal, and Y-axis is the length direction of terminal, and for Z axis perpendicular to the screen of terminal, Z axis trend is face
To the direction of user.Terminal is subject to gravitation to act on, and can generate a gravity acceleration g vertically downward, g=9.8m/
S2.When terminal front side is kept flat upwards, X-axis, Y-axis, the acceleration of gravity numerical value of Z axis are 0,0, -9.8 respectively.When terminal is overturn
Face down placement when, X-axis, Y-axis, the acceleration of gravity numerical value of Z axis are 0,0,9.8 respectively.
Normal reading posture overlooks terminal screen, and screen faces up, and Z axis acceleration value is less than 0.Recumbency makes
During with terminal, terminal screen is looked up, screen faces down, and Z axis acceleration value is more than 0.During recumbency using terminal, terminal with
Horizontal plane is into a smaller angle, typically less than 90 °, specifically as shown in figure 3, being added by three axis being integrated in terminal
Velocity sensor can detect the numerical value of Az, i.e. Az=g*cos θ, the angle between θ GC group connectors plane and horizontal plane.With
The reduction at θ angles, Az components gradually increase, and the angle that can be calculated by Az components between end plane and horizontal plane is believed
Breath.Constantly switch between both of which in order to avoid detecting state under critical condition, detection angle can take 80 ° or so, Az=
G*cos80 °=0.17g, detection threshold value takes 0.17g.When | Az | >=0.17g, and Az is timing, it can be determined that it is that recumbency uses eventually
End.As it can be seen that reading posture and the gravity acceleration value of Z axis forward direction have correspondence, so, it, can be pre- in the embodiment of the present invention
The correspondence of gravity acceleration value and reading posture is first determined, so that subsequent reading posture judges.
Further, in an alternate embodiment of the present invention where, a kind of fault tolerant mechanism is provided, so as to improve reading appearance
The detection accuracy of gesture.Specifically, in the present embodiment, terminal obtains the 3-axis acceleration sensor in setting time interval and adopts
The gravity acceleration value of the Z axis forward direction collected asks for the average value of the acceleration of gravity of Z axis forward direction in the time interval；And root
According to default gravity acceleration value and the correspondence of reading posture, the average value pair of the acceleration of gravity asked for is determined
The reading posture answered.Wherein, the time interval of setting is usually less than second grade.The present embodiment avoids user by averaged
Maloperation caused by false judgment.
Further, in an alternate embodiment of the present invention where, when the reading posture determined is the wrong appearance specified
During gesture, alarm is exported.Wherein, the type of alarm includes：Information alert and/or auditory tone cues.
In summary, the embodiment of the present invention, using 3-axis acceleration sensor acquisition perpendicular to terminal screen direction
Gravity acceleration value, it can be determined that go out the reading posture of user, solving terminal in the prior art well can not be to user's
The problem of reading posture is detected.And the embodiment of the present invention can also the reading posture detected be incorrect posture when,
Alarm is sent, plays good supervisory role, improves the usage experience of user.
