In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structure intention of the display control unit of the utility model embodiment.
Fig. 2 is the concrete structure intention of the display control unit of the utility model embodiment.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.
Please refer to shown in Figure 1ly, the display control unit 100 that the user uses comprises camera 101, gyroscope 102 and display screen 103, and in the present embodiment, display control unit 100 is preferably handheld device.Camera 101 is preferably the eye tracking camera, and this camera 101 is built in the display control unit 100, is used to follow the tracks of eyes of user to obtain the positional information of eyes of user.Gyroscope 102 is built in the display control unit 100 and is connected with camera 101; Be used to survey display control unit to obtain the mobile message of display control unit 100; Preferably, display control unit 100 move for display control unit 100 rotations wait cause towards variation.Display screen 103 is preferably the display screen that can be used for showing three-dimensional content, and this display screen 103 is used for carrying out according to the positional information of eyes of user the demonstration of three-dimensional content.
Fig. 2 is the concrete structure figure of display control unit.Based on Fig. 1 and above-mentioned display control unit 100; This display control unit also has switch 104; This switch can initiatively open or cut out by the user; This switch 104 is connected with clock 105 with gyroscope 102 respectively in addition, also can work as moving range that gyroscope 102 gets access to moving of display control unit 100 or this display control unit 100 in preset scope the time, and gyroscope 102 trigger switches are opened; In the time of setting at clock 105, gyroscope 102 does not detect that display control unit 100 moves or the moving range of this display control unit 100 not in preset scope the time, and switch 104 cuts out.
Please continue with reference to shown in Figure 2; Display control unit 100 also comprises display direction control module 106; This display direction control module 106 is connected with display screen 103 with camera 101 respectively, and the positional information of the eyes of user that is used for getting access to according to camera 101 is confirmed the display direction of content at display screen 103.If for the bore hole three-dimensional display, thereby this display direction control module 106 realizes the control to display direction according to the physical location of eyes of user positional information control lens blooming on display screen 103.
When using the display control unit 100 of the utility model; In the phase I; For example after the user initiatively opens camera 101 or gyroscope 102 triggering unlatching cameras 101; The positional information that eyes of user was followed the tracks of and got access to 101 pairs of eyes of user of camera, wherein the positional information of eyes of user can comprise the information such as angle and distance of eyes of user with respect to display screen 103.In this phase I, eyes of user is set at primary importance in the present embodiment with respect to the position of the display screen 103 of display control unit 100.Display direction control module 106 is confirmed the display direction of three-dimensional content at display screen 103 according to this primary importance, and carries out the demonstration of three-dimensional content through display screen 103.In second stage; If gyroscope 102 detects that display control unit 100 has taken place to move or the moving range of this display control unit 100 in preset scope; Then triggering the switch 104 of camera 101 opens; Camera 101 scans, and gets access to the reposition of eyes of user with respect to display screen 103, is set at the second place in the present embodiment; Display direction control module 106 is confirmed the display direction of three-dimensional content at display screen 103 according to this second visual angle 302, and carries out the demonstration of three-dimensional content through display screen 103.In the phase III, if surpassed the setting-up time of clock 105, gyroscope 102 does not detect that display control unit 100 moves or the moving range of this display control unit 100 not in preset scope the time, then triggers the switch 104 of camera 101 and closes.
