Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, technical scheme is further described.
Shown in Figure 1, a kind of method being dynamically determined the window's position in the display device, comprise the following steps:
Step S101, before the window of program shows, first carries out recognition of face, subsequently into step S102.
As a preferable embodiment, the above-mentioned process carrying out recognition of face specifically may include that installs the device (referred to as face recognition device) with face recognition function the most on the display device, when the window being found to have program needs to show, then start described face recognition device and carry out recognition of face, face recognition device can scan display device front after starting automatically, identifies the face of people.
Step S102, calculates the eye relative tertiary location relative to display device according to face recognition result, subsequently into step S103.
As a preferable embodiment, the locus of above-mentioned counterpart's eyes may include that eye is to the distance of display device, eye distance at distance display device edge up and down on the direction parallel with screen.
Step S103, according to the visual angle of watching attentively of described relative tertiary location and human eye, calculates best image region (also known as " optimal viewing region ", i.e. user people on the display device can see the region of object at once clearly), subsequently into step S104.
The above-mentioned scope watching visual angle attentively about human eye is chosen, owing to the visual angle of watching attentively of different people may be different, therefore as a preferable embodiment, the present embodiment is as the criterion with the visual angle of normal person under normal circumstances, field of front vision angle when i.e. motionless, eye is movable, particularly as follows: centered by human eye, above 40 degree, following 50 degree, each 55 degree of two sides, left and right.The most simply for one of them example, user can arrange more smaller than the angle being given above equally possible as the case may be.
It is described in detail how calculating described best image region below:
Assume initially that used in the present invention for the display device screen upper left corner as zero (0,0,0) position, with underface for y-axis forward, be parallel to display device display surface to the right for x-axis forward, be perpendicular to display surface towards user direction the rectangular coordinate system in space for z-axis forward；It is then assumed that the relative tertiary location of human eye be (a, b, c), human eye watch attentively above visual angle for A degree, below for B degree, the left side be C degree, the right side be D degree；And use equation below to calculate, best image region [(x1, y1), (x2, y2)] in display device screen:
x1=a-tanC*c；
Y1=b-tanA*c；
x2=a+tanB*c；
y2=b+tanD*c。
Step S104, is obtaining behind best image region, according to described best image region and the size of program window that will show, calculates the final displaing coordinate of described program window.
As a preferable embodiment, according to described best image region and the size of program window, described program window can be shown centered in described best image region.It is described being shown centered on calculating below:
Assume that program needs the size of the window of display to be width: w, high: h.Then can calculate region [(x3, y3), (x4, y4)] placed in the middle for showing program window:
x3=x1+((x2–x1)–w)/2；
y3=y1+((y2–y1)–h)/2；
x4=x3+w；
y4=y3+h。
It addition, find in actual applications, after calculating final displaing coordinate, sometimes described in the program window that is shown centered on can be beyond the scope of display device screen coordinate.In this case, then can be after step S104 calculates final displaing coordinate, it is further added by step S105: the program window being shown centered on described in if is beyond the scope of display device screen coordinate, then the coordinate beyond display device screen is modified so that program window is fully displayed in display device screen.
Above-mentioned correction specifically can be such that beyond the process of the coordinate of display device screen
If x3 < 0, then it is adjusted to: x3=0；x4=w；
If y3 < 0, then it is adjusted to: y3=0；y4=h；
If x4 > screen width, then it is adjusted to: x4=screen width；X3=screen width w；
If y4 < screen height, then it is adjusted to: y4=screen height；Y3=screen height-h.
After being modified, finally according to the region displaying program window after adjusting.
As a preferable embodiment, the size of heretofore described display device is more than 32 inches.
Corresponding with a kind of above-mentioned method being dynamically determined the window's position in the display device, the present invention also provides for a kind of device being dynamically determined the window's position in the display device, shown in Figure 2, including:
Face recognition module (101), for before the window of program shows, first carries out recognition of face；
