The architecture, method steps, and application examples of the system for displaying the rotation of the screen according to the preferred embodiment of the present invention will be described with reference to the related drawings, wherein the same structures, steps, and elements will be described with the same reference numerals. In order to facilitate understanding, the structures, steps and components not directly related to the present case will be omitted and not drawn. In addition, the electronic display device referred to below may be a notebook computer, a tablet computer, a desktop computer, or a smart phone, and is not limited to the above.

Please refer to FIG. 1 first, which is an architectural diagram of a system for displaying a screen rotation. The system 1 of the present invention includes an image capturing unit 11, an analyzing unit 12, and a processing unit 13. System 1 may further include an execution unit 14. In detail, the analyzing unit 12 is electrically connected to the image capturing unit 11; the processing unit 13 is electrically connected to the analyzing unit 12. The execution unit 14 is electrically connected to the processing unit 13.

The image capturing unit 11 can capture user information relative to the electronic display device. In other words, the image capturing unit 11 can capture the image of the user and convert it into coordinates, so that the system can know the user and the electronic display device. Relative positional relationship (for example, whether the user browses in the same direction as the display).

The image capturing unit 11 of the present invention can be, for example, an eye tracking component, and the eye tracking component can capture the user's eye image, eye coordinates, or a combination thereof, and transmit the image to the analyzing unit 12. The eye image referred to herein is a line connecting the contours of the user's eyes, and the eye coordinates can define the contour line of the iris by positioning the intersection of the iris and the conjunctiva. However, whether it is an eye image, an eye coordinate, or a combination thereof, it is converted into an absolute coordinate after being captured, and transmitted to the analyzing unit 12. Alternatively, the image capturing unit 11 of the present invention may also be an imaging component (such as a camera) for capturing an eye image, an eye coordinate, a facial image, a head contour, an upper body contour, or a combination thereof. The captured information is transmitted to the analysis unit 12 to further analyze the relative relationship between the user and the display screen.

Next, the analyzing unit 12 receives the captured user information and generates analysis information according to the user information. The analysis information here may be the user's eye coordinate (eyeball tracking element) or the inclination angle of the user's head image, depending on the image capturing unit 11 to be matched. In detail, if the eye tracking component is used, the captured image can be mapped to the display screen and the eye coordinates are generated, and the analyzing unit 12 can know whether the user's browsing line of sight (or the moving path of the browsing) is displayed. The picture or arrangement is in the same direction. If the imaging element is used, the analysis unit 12 further analyzes the image, for example, the image sensor can capture the head image, and then analyzes the relative position of the user's nose and lips in the head image to determine the user. Whether the head has a tilt angle and whether the browsing direction is in the same direction as the display screen.

After receiving the analysis information, the processing unit 13 generates a control signal according to the analysis information, and the control signal is used to control the display screen of the electronic display device to rotate. After the execution unit 14 receives the control signal, the display screen can be rotated by an angle. For example, the analysis information indicates that the user's head is tilted to the right by more than 45 degrees. At this time, the processing unit 13 will instruct the execution unit 14 to rotate the display screen 90 degrees clockwise. On the other hand, if the analysis information indicates that the angle of the user's head is less than 45 degrees, the processing unit 13 instructs the execution unit 14 not to rotate the display screen (the control unit 14 may not directly transmit any control signals, so that the execution unit 14 assumes the standby state).

It should be noted that although the processing unit 13 and the execution unit 14 of the embodiment are independent units and architectures, the processing unit 13 and the execution unit 14 may be combined on a single wafer to achieve the same effect as the embodiment. This case is not limited to this.

The system 1 of this embodiment further includes a rotation starting unit 10, and the image capturing The unit 11 is electrically connected to select and activate the image capturing unit 11. In other words, if the rotation starting unit 10 selects to activate the image capturing unit 11, an activation signal is transmitted to the image capturing unit 11 to activate the image capturing unit 11. In actual operation, the electronic display device can set the operation interface of the setting menu (such as but not limited to the user interface (UI)) or the physical button in the software interface or appearance, so that the user can select whether to start the rotation. mode. If you choose not to activate the rotation mode, you can use a gyroscope, a magnetic sensor, or a gravity sensor as a way to judge the rotation of the display screen.

It should be added that the "rotation display screen" referred to in this case is not limited to rotating only the initial display screen. If the initial screen has multiple independent images (such as software shortcuts or shortcut keys), it will be rotated. Also adjust to the most consistent arrangement of the picture.

In addition, in the present case, "the direction in which the user browses and the display screen are in the same direction" means that if the user's browsing order is from top to bottom, the preferred display screen and the direction of the arrangement are also Top to bottom, and the direction of browsing here should not be confused with the reading direction.

Please refer to FIG. 2 again, which is another architectural diagram of the system for displaying the screen rotation. The difference from the previous embodiment is that the system 1a of the present architecture does not include the rotation starting unit 10, but is only electrically connected to the image capturing unit 11 through the processing unit 13, and the activation signal is transmitted by the processing unit 13, and the rotation is started. mode. In other words, the execution unit 14 can be directly controlled by the processing unit 13 and the image capturing unit 11 can be activated.

The rest of the architecture and the connection relationship between the units are the same as those of the foregoing architecture, and therefore will not be described again.

Please refer to FIG. 3 to FIG. 5 together. FIG. 3 is a flow chart showing the steps of the method for displaying the rotation of the screen, and FIG. 4 and FIG. 5 are schematic diagrams showing the application of the method for displaying the rotation of the screen. The method of rotating the display screen of the present invention is applied to an electronic display device 2, and the electronic display device 2 includes a display screen 22. The electronic display device 2 can be a smart phone, a desktop computer, a tablet computer, or a notebook computer. The drawing is a tablet computer, and the image capturing unit 11 is disposed on one side of the display screen 22, but the electronic device The type and configuration of the display device 2 are not limited thereto.

Referring first to the flowchart of FIG. 3, the method for rotating the display screen of the present case includes at least the following steps S1 to S4: First, the rotation mode is started (step S1). The display screen 22 can have a operation As an interface (not shown), the operation interface can be, for example but not limited to, a user interface (UI), and the user can activate the rotation mode through the operation interface. In other implementations, the launch rotation mode can also be achieved via a physical button.

Next, the user information with respect to the electronic display device 2 is captured by the image capturing unit 11 (step S2). Different user information can be retrieved according to the image capturing unit 11 herein. If the image capturing unit 11 is an eye tracking component, the user information may be an eye image, an eye coordinate, or a combination thereof. If the image capturing unit 11 is an imaging element, the user information may include an eye image, an eye coordinate, a facial image, a head contour, an upper body contour, or a combination thereof.

Then, the user information is received through the analysis unit, and the analysis information is generated according to the user information (step S3), and the analysis information can be, for example, the user's eye coordinates.

The processing unit then receives the aforementioned analysis information and generates a control signal based on the analysis information (step S4).

In addition, the method of the present invention may further include step S5. The processing unit determines, according to the analysis information, whether the user's line of sight or head tilt direction has reached a level at which the display screen needs to be rotated. If it is judged that rotation is required, the control unit receives the control signal again and rotates the display screen by an angle (step S5).

For example, when the tilt angle exceeds 45 degrees clockwise (eg, FIG. 5), the processing unit provides a control signal instructing the execution unit to rotate the display screen 90 degrees clockwise (the display screen 22a of FIG. 5 has been rotated 90 degrees) for use in conjunction with The direction of the user's browsing. At this point, the user can continue to view photos, videos, or browse websites without having to rotate or tilt the electronic display device.

Alternatively, when the tilt angle does not exceed 45 degrees (for example, FIG. 4), it is determined that the angle does not need to be rotated to display the screen 22. At this time, the processing unit will transmit a control signal to the execution unit (or not transmit any signal, causing the execution unit to continue to stand by), so that the display screen 22 does not rotate.

The connection relationship between the remaining units and components is the same as that of the foregoing system, and therefore will not be described again.

The method of the present invention may further include step S0, selecting to initiate the rotation mode. Through the operation interface (such as user interface) or physical button, the user can choose whether to activate the rotation mode according to the needs.

In summary, the method and system for displaying the rotation of the screen use the image capturing unit to capture the image of the user, and then analyze the information of the user's eyes, face or outline, so that the user does not need to rotate the electronic display. The device itself can directly and intuitively rotate the display. Therefore, the system and method can provide a better and more intuitive experience for the user, and the judgment method is more accurate than the conventional method of judging only the absolute angle of rotation and tilt of the device.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or changes made to the spirit and scope of this case shall be included in the scope of the appended patent application.
