3rd susceptibility (highest susceptibility) of two susceptibilitys is rotated controlling the picture shown by display module 18.
Now, if the angle between the portable electronic devices 1 that are sensed of gravity sensing module 12 and horizontal direction is
Less than or equal to predetermined angle (such as 90 degree), the angle M1=90 degree as shown in Fig. 3 A, then the meeting of control module 16 will be portable
Electronic installation 1 switches to the first use pattern (such as sitting posture pattern)；If the portable electricity that gravity sensing module 12 is sensed
Angle between sub-device 1 and horizontal direction is more than predetermined angle (such as 90 degree), the angle M2 as shown in Fig. 3 B>90 degree,
Then portable electronic devices 1 can be switched to the second use pattern (for example couch pattern) by control module 16, but are not limited.
In this embodiment, in order to more accurately judge whether user is watching and operating portable electronic to fill
1 is put, control module 16 further includes humanoid feature identification unit 160.Assuming that distance sensing module 14 is using supersonic
Mechanism enters the sensing of row distance, then humanoid feature identification unit 160 can couple the first ultrasonic receiving unit 142 and according to default
Whether there is human figure in humanoid feature decision prospect state.

Before, then control module 16 that the picture shown by display module 18 can be controlled not rotated.If humanoid feature identification unit
160 differentiation result is yes, represents user and is sitting at before portable electronic devices 1, then control module 16 again to enter one
Walk whether the distance between the speed according to the translational speed of portable electronic devices 1, portable electronic devices 1 and object change
And the sensing result such as the corner dimension between portable electronic devices 1 and horizontal direction decides whether to rotation its display mould
Picture shown by group 18.
Additionally, the triangle that the crown P1 of human body and two shoulder P2, P3 are collectively forming is also used to judge portable electronic
Whether the angle between device 1 and user changes, that is, whether user is inclined portable electronic devices 1.
As shown in Fig. 5 A and Fig. 5 B, for example, under the very first time, the crown P1 of the human body in script Fig. 5 A with can take
The distance between formula electronic installation 1 d2 is equal to the distance between two shoulder P2, P3 and portable electronic devices 1 of human body d1.In
Under two times, as shown in Figure 5 B, two shoulder P2, P3 of human body and portable electricity are caused because portable electronic devices 1 are tilted backwards
