The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

detailed description

Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

Please refer to FIG. 1 and FIG. 2 , a preferred embodiment of an electronic device 10 (such as a mobile phone, a tablet computer and other portable electronic devices) of the present invention includes a memory 108, a gravity sensor 110, a screen 106, a viewing angle detection device 112 and A processor 100 connected to the memory 108 , the gravity sensor 110 , the screen 106 and the viewing angle detection device 112 .

In this embodiment, the gravity sensor 110 is used to output the gravity signal of the electronic device 10 relative to the gravity direction, so as to judge whether the direction of the electronic device 10 relative to the gravity changes according to the gravity signal.

The screen 106 is used to display several interfaces 105, including but not limited to application program interfaces, application program icons, system desktop and so on.

The viewing angle detecting device 112 is used for outputting an angle a between the line of sight 200 of the user 20 and the screen 106 when the user 20 watches the screen 106 .

In this embodiment, the viewing angle detecting device 112 includes an infrared detector 102 and a camera 104 disposed on the electronic device 10 . The infrared detector 102 is used to output infrared signals. When the infrared signal encounters the cornea of the eye of the user 20 , the infrared detector 102 can form a light spot (Pulchin's spot) with a reflective bright spot on the cornea of the eye of the user 20 .

The camera 104 is used to take pictures of the eyes of the user 20 to obtain an eye image of the user 20 . The eye image of the user 20 includes the image of the light spot and the pupil formed by the infrared detector 102 on the cornea of the user 20's eye.

The memory 108 stores the angle a between the line of sight 200 of the user 20 and the screen 106 corresponding to the positional relationship between the light spot and the center of the pupil, so that the angle a between the line of sight 200 of the user 20 and the screen 106 can be determined according to the eye The positional relationship between the spot and the center of the pupil in the external image is determined. In other embodiments, the angle a between the line of sight 200 of the user 20 and the screen 106 can also be obtained by other electronic devices.

The processor 100 includes a control module 101 and a driver module 103 .

The control module 101 is used to obtain the eye image output by the camera 104, and the control module 101 is also used to process the eye image to obtain the positional relationship between the light spot and the pupil center in the eye image. The control module 101 also acquires the corresponding included angle a from the memory 108 according to the positional relationship between the pupil center and the light spot in the user's eye image.

According to the working principle of the electronic device 10 , generally, the angle c between the interface 105 and the screen 106 is parallel. At this time, the driving module 103 can determine whether the user 20 and the viewing interface 105 are in a squinted state or a normal state according to the included angle a. For example, when the line of sight 200 of the user 20 is perpendicular to the screen 106, that is, when the angle a output by the viewing angle detection device 112 is a right angle, it means that the user 20 and the interface 105 displayed on the screen 106 are in a normal state. At this time, The driving module 103 does not adjust the angle of the interface displayed on the screen 106 . In other embodiments, when the angle a between the line of sight 200 of the user 20 and the screen 106 is approximately perpendicular, the user 20 and the interface 105 displayed on the screen 106 can also be considered to be in a normal state.

When the user 20 and the interface 105 displayed on the screen 106 are in a squint state, such as the angle a between the line of sight 200 of the user 20 and the screen 106 is less than 45 degrees, the driving module 103 adjusts according to the angle a The angle c between the screen 106 and the interface 105 . In this embodiment, in order to make the user 20 and the interface 105 in the electronic device 10 be in a normal state, that is, the angle b between the line of sight 200 of the user 20 and the interface 105 is a right angle (such as 90 degrees) or approximately a right angle , the driving module 103 adjusts the angle c between the interface 105 and the screen 106. According to the triangular relationship formed by the line of sight 200, the interface 105, and the screen 106, it can be known that c=90-a, that is, the angle c between the line of sight 200 of the user 20 and the screen 106 The sum of the included angle a between the interface 105 and the adjusted angle c between the interface 105 and the screen 106 is a right angle or approximately a right angle. In this way, the user 20 and the viewed interface 105 are in a normal state.

In this embodiment, the driving module 103 performs at least one scaling, rotating, and translating operation on the interface 105 in the screen 106 to make the angle c between the screen 106 and the adjusted interface 105 and the line of sight 200 of the user 20 and the screen 106 The sum of the included angles a is a right angle or approximately a right angle.

In other embodiments, the drive module 103 is also used to judge whether the user 20 and the viewing interface 105 are in a squinted state or a normal state according to the included angle a and the angle c between the interface 105 and the screen 106; When the interface 105 is in a squint state, if the sum of the angle c and the included angle a is not a right angle or approximately a right angle, the drive module 103 adjusts the angle c between the screen 106 and the interface 105, so that the adjusted interface 105 and The sum of the angle c and the included angle a between the screens 106 is a right angle or approximately a right angle; when the user 20 and the viewing interface 105 are in a normal state, such as when the angle c and the included angle a are complementary angles, the drive module 103 maintains The angle c displayed between the screen 106 and the interface 105 remains unchanged.

In step S204, the processor 100 controls the infrared detector 102 to emit an infrared signal to form a light spot on the cornea of the eye of the user 20 . In this embodiment, when the direction of the electronic device 10 relative to gravity changes, the processor 100 controls the infrared detector 102 to send an infrared signal, which is beneficial to reduce power consumption of the electronic device 10 . In other implementations, the processor 100 can also control the infrared detector 102 to emit infrared signals in real time.

In step S206 , the processor 100 controls the camera 104 to acquire an eye image of the user 20 .
