Description

Computer with automatic adjustment of display screen angle

The present invention relates to a computer, and more particularly to a computer having an automatic adjustment function for displaying a viewing angle of a screen.

Existing display screens are manually adjusted for their angle. Especially the last adjusted angle, the next time you turn on the phone, you often need to manually re-adjust it manually.

Many computers (including laptops, tablets, or allin ones) now have gravity sensors on their display screens. Therefore, traditionally, some notebook computers have an automatic adjustment function, that is, when the power is turned on, the angle of the display screen is adjusted to the same angle before the previous shutdown (for example, as described in Taiwan Patent No. 201233293). However, when the user moves the notebook from the horizontal desktop to the thigh, or to other non-horizontal places, the display screen is not the angle that the user really wants.

In addition, if you use a computer while moving, for example, in a car, the gravity sensor will be affected by acceleration or deceleration, but not accurate enough.

It is therefore necessary to provide a modified computer with the function of automatically adjusting the display screen angle.

It is an object of the present invention to provide a computer having the function of automatically adjusting the display screen angle.

To achieve the above objective, the present invention provides a computer including a display screen, a base, a rotating module, a gravity sensor, a controller, and a memory. The rotating module includes an encoder, which is respectively connected to the display screen and the base, and can rotate the display screen relative to the base, and the encoder detects the rotation angle of the display screen relative to the base. The gravity sensor is located on the display screen, and the gravity sensor is used to detect a gravity angle between the display screen and a gravity direction. The controller is electrically connected to the encoder and the gravity sensor respectively, and calculates a first angle between the display screen and the base according to the rotation angle, and the controller calculates the display screen according to the gravity angle The second angle with a horizontal line. The memory is electrically connected to the controller, and the memory stores the first angle of the encoder. When the computer is placed horizontally, the first angle and the second angle should be equal. When the base is not in the horizontal position, the first angle and the second angle are not equal, the controller rotates the display module to compensate for the difference angle according to the difference angle between the second angle and the first angle.

In one embodiment, the computer is a notebook computer and the base is a keyboard. Preferably, the display screen is a touch panel. When the first angle is greater than 180 degrees, the controller controls the display content of the display screen to be reversed up and down for the user to read/view.

The angle of gravity between the screen and the gravitational direction of the gravitational force, the gravity angle data obtained many times can be used to analyze the state of use of the computer at that time (such as static state, high-speed movement, acceleration, deceleration or user movement, etc.); The average value of the gravity angle obtained this time is set to the second angle, which can be used to reduce the actual angular error of the computer. The software performs or does not need to perform the angle compensation action according to different usage states; for example, the gravity sensor detects hundreds of times every 2 minutes, and after the software analysis judges the degree of change of the detection value, the computer can be known What state, if the program judges that the screen is reset to a static state of another angle by the user's preset value of 100 degrees, it means that the computer is moved to a plane with different tilt angles, then it is taken multiple times. After the average value of the measured value is obtained, the second angle is obtained, and then the angle difference between the 100 degree and the second angle is compensated in the control rotation module; if the software analysis determines that the computer is in an unchanging angle state or the user moves vigorously The state does not need to take the average and compensate the difference angle.

Preferably, the computer further includes a second gravity sensor, the second gravity sensor is located on the base, and is configured to detect a second gravity angle between the base and the gravitational direction of the gravitational force, The controller calculates a third angle between the display screen and the base according to the second angle of gravity, and the third angle is used to correct the difference angle.

The computer further includes a voice control module (including a microphone, a voice recognition software or a hardware, a command library), the voice control module is configured to recognize a voice input, and the controller controls the rotation module according to the voice input to make the display screen Rotate relative to the base.

The computer further includes an image capturing device and an eye recognition module (for example, a conventional face recognition determines that the eye is located at a Y-axis height in front of the screen), and the image capturing device can capture a user's eye position or The average position of the Y-axis of the eye position of a plurality of users, after the software calculates the direction of movement of the screen, the controller starts to control the rotation module to move the display screen, and the eye recognition module continues to dynamically detect. The eye position is measured until the eye position reaches the appropriate position set by the software, and the software stops automatically adjusting the screen. The time of each automatic adjustment can be set according to the user's preference time. For example, the system automatically detects every 5 minutes. Adjust the screen angle once.

The computer further includes an image capturing device and a gesture recognition module, wherein the image capturing device captures a gesture or a plurality of gestures, and identifies the gesture direction of the user through the gesture recognition module, wherein the controller is configured according to the user A direction gesture or a stop gesture, controlling the rotation module to rotate or stop the display screen relative to the base.

In order to enable the reviewing committee to better understand the technical contents of the present invention, the preferred embodiments are described below.

Referring to FIG. 1 and FIG. 2 simultaneously, the computer provides a display screen 1, a base 2, a rotating module 3, a gravity sensor 4, a controller 7, and a memory 6. The rotating module 3 includes an encoder 31. The rotating module 3 is connected to the display screen 1 and the base 2 respectively, and can rotate the display screen 1 relative to the base 2, and the encoder 31 can detect the rotation angle of the display screen 1 relative to the base 2. The gravity sensor 4 is located on the display screen 1. The gravity sensor 4 is used to detect the angle between the display screen 1 and the direction of the gravitational force of the earth (designated as the angle of gravity to be separated from other angles).

The controller 7 is electrically connected to the encoder 31 and the gravity sensor 4 respectively. The controller 7 calculates the angle between the display screen 1 and the base 2 according to the rotation angle measured by the encoder 31 (converted to the high and low potential sequence and the number of times of the electrical signal) (named as the first angle, to phase with other angles) Separately, and the controller 7 calculates an angle between the display screen 1 and a horizontal line according to the angle of gravity (designated as a second angle to be separated from other angles). The memory 6 is electrically connected to the controller 7, and the memory 6 stores the first angle measured by the encoder 31.

When the computer is placed horizontally, the first angle obtained by the controller 7 according to the encoder 31 and the second angle obtained by the gravity sensor 4 should be equal, because the second angle is the display screen 1 as described above. The angle between the horizontal line and the horizontal line.

Referring to FIG. 3A, the user can press the button 101 to activate, so that the controller 7 controls the display screen 1 to be rotated open or closed relative to the base 2. Furthermore, the rotary module 3 can further include a rotary motor 32. The rotation motor 32 is electrically connected to the controller 7, and the display of the screen 1 by the rotation motor 32 is a known technique, and therefore will not be described herein. For example, the buttons 101 of the left and right arrows respectively represent opening or closing. When the user presses the button 101, the angle between the display screen 1 and the base 2 can be moved from Θ2 to Θ1, at which time Θ1 is set to a suitable angle for the user.

However, as shown in FIG. 3B, when the base 2 is not in the horizontal position, the first angle calculated by the encoder 31 in the memory 6 and the second angle calculated by the gravity sensor 4 are two angles. Not equal. However, in the case of Fig. 3B, Θ1 is not a suitable angle for the user. At this time, the first angle calculated by the encoder 31 stored in the memory 6 is Θ1, but the second angle calculated by the gravity sensor 4 is Θ3. At this time, the controller 7 of the present invention will automatically rotate the display screen 1 according to the difference angle Θ' between the second angle Θ3 and the first angle Θ1, and rotate the difference angle Θ', so that the display screen 1 remains Located at the right angle for the user.

In order to detect various usage states of the computer and reduce the detection error of the gravity angle, the controller 7 controls the gravity sensor 4 to detect several times to thousands of times (the number of times can be adjusted by the software), and detects and records multiple times. Displaying the angle of gravity between the screen 1 and the direction of gravity, the angle of gravity obtained multiple times can be used to analyze the state of use of the computer at that time (such as stationary state, high-speed movement, acceleration, deceleration, or user movement, etc.) And the angle of gravity obtained from the multiple times is taken as the average value of the second angle, which can be used to reduce the actual angular error of the computer. The software performs or does not need to perform the angle compensation action according to different usage states; for example, the gravity sensor 4 detects hundreds of times every 2 minutes, and after the software analysis determines the degree of change of the detection value, it can be known What state is the computer currently in? If the program judges that the screen 1 is reset to a static state of another angle by the user's preset value of 100 degrees, it means that the computer is moved to a plane with different tilt angles. After the average value of the measured value is obtained multiple times, the second angle is obtained, and then the angle difference between the 100 degree and the second angle is compensated in the control rotation module. If the change of the angle of gravity of any two detections is greater than a second set angle (for example, if the change is greater than 30 degrees, which may be a moving violent movement state), the calculation of the average value is not included. For example, if the software analysis determines that the computer is in an unchanging angle state or the user moves the violent moving state, it is not necessary to take an average value and compensate for the difference angle.

Furthermore, please refer back to FIG. 1 , the computer may further include a second gravity sensor 4 ′, the second gravity sensor 4 ′ is located on the base 2 for detecting the base 2 and the ground. a second angle of gravity between the gravitational directions, the controller calculates an angle between the display screen 1 and the base 2 according to the second angle of gravity (designated as a third angle to be distinguished from other angles), and The third angle is used to correct the difference angle. For example, when the user is in the car, when the computer is in a non-horizontal position and has a forward speed, the two gravity sensors 4 are respectively located on the display screen 1 and the base 2, and when two sets of relative angles are obtained, the encoder 31 is used. The measured absolute mechanical displacement, the controller 7 calculates the absolute angle, whereby a more accurate angle of angle can be obtained.

In the above embodiment, the computer is a notebook computer, and the base is a keyboard, and the display screen 1 can be an LCD screen or a touch panel (touch screen). If the computer is a dual screen computer, the base is the second screen.

Referring to FIG. 3C, when the display screen 1 is a touch panel, the user can use the base 2 of the computer as a support. When the second angle calculated by the gravity sensor 4 is greater than a set angle, for example, 100-200 degrees, preferably 180 degrees, the controller 7 of the present invention reverses the display content of the display screen 1 to User reading/viewing. In this embodiment, the base 2 may further include a foot pad 21 to prevent slipping. The display screen 1 further includes a circular arc edge 11 (or a tiny wheel structure) to facilitate sliding during automatic rotation.
