Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following descriptions.
As shown in fig. 1, in the method for adjusting an LCD display capable of adjusting position and angle described in the present invention, a microprocessor of the LCD display capable of adjusting position and angle processes eyeball movement data detected by an eyeball tracker in real time to obtain a gazing position of an eyeball; the data of eyeball movement can also be extracted by software by using a camera.
The microprocessor of the LCD display capable of adjusting the position and the angle judges whether the eyeball gazes at the position in the screen of the display, and the screen moves along with the movement of the eyeball when the eyeball gazes at the position in the screen; and the position watched by the eyeballs is not in the screen, and the screen does not move along with the eyeballs.
The microprocessor of the LCD display with the adjustable position and angle judges whether the sight line is vertical to the screen, and the position and the inclination angle of the LCD display with the adjustable position and angle are not vertical to the screen, so that the plane of the screen position watched by the eyeballs is vertical to the sight line. The distance measuring sensor detects the distance between the eyeball and the LCD display capable of adjusting the position and the angle, a safety distance range is preset, the distance between the eyeball and the display is within the preset range, and if the distance is not within the preset distance range, the distance measuring sensor prompts a user. And adjusting the brightness of the LCD display with the position and the angle adjustable to be a set brightness value corresponding to the distance according to the detected distance within the preset safe distance range.
The method comprises the steps that a position adjusting and establishing mode takes an LCD display base with adjustable position and angle as an original point, the vertical direction is a Z axis, the horizontal direction is a Y axis, the direction vertical to a ZY plane is an X axis, a microprocessor obtains coordinates (Y, Z) of a sight line and the ZY plane which are vertically crossed, an LCD display area with adjustable position and angle watched by eyeballs moves to the coordinates (Y, Z) along the Z axis and then along the Y axis, a distance sensor detects the distance between the eyeballs and a screen, and a user is reminded to adjust the distance to be within a preset safety range when the distance exceeds the range.
The angle adjustment in the method is to obtain the inclination angle between the face and the horizontal plane through the face recognition by a microprocessor of an LCD display capable of adjusting the position and the angle, obtain the inclination angle value, and then adjust the inclination angle of the screen to enable the plane of the screen to be parallel to the face.
