Embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
As depicted in figs. 1 and 2, Fig. 1 is that the inventor observes the structural representation of seeing mobile device, and Fig. 2 is that the present invention regulates user to watch the schematic flow sheet of the method for mobile device in suitable distance.The method comprises the following steps:
Step S101: control camera photographic images in the coverage of camera.
In step S101, preferably the in the situation that of mobile device 10 normal demonstration, periodically control photographic images in the coverage of camera at camera, as detected once every 60 seconds.Wherein coverage is preferably less than 5m, and barrier is preferably people, and camera preferably automatically detects people in the coverage of camera, and other barriers do not detect as animal, solid body.
Step S102: whether have barrier in detected image.
Step S103: if detect and have barrier in image, detect in barrier and whether have human eye by iris recognition technology.
Wherein, if do not detect and have barrier, return to step S101 in coverage.Certainly, in other embodiments, the image that can also utilize continuous Ada Boost algorithm traversal camera to detect completes the fine positioning of human eye.
Step S104: if detect and have human eye, judge that human eye is whether in the angular field of view in mobile device 10 in barrier.
In step S104, if do not detect and have human eye, return to step S101 in barrier.As shown in Figure 1, when human eye is in A place or when B place, in the angular field of view β of human eye in mobile device 10; When human eye is during in C place, human eye is not in the angular field of view β in mobile device 10.In the present embodiment, by the size of mobile device 10 regulatable vision angle range beta.
Step S105: if judged in the angular field of view of human eye in mobile device 10, utilize the distance value of ultrasound examination human eye and mobile device 10.
Wherein, if judge that human eye not in the angular field of view in mobile device 10, returns to step S101.If judged in the angular field of view of human eye in mobile device 10, detect the distance value of human eye and mobile device 10, as shown in Figure 3, utilize the distance value of ultrasound examination human eye and mobile device 10 to comprise following sub-step:
Step S1051: send ultrasound wave towards human eye direction of living in, start timing simultaneously.
Step S1052: receive the ultrasound wave reflecting from angular field of view, finish timing, to obtain time t simultaneously; The ultrasound wave wherein reflecting from angular field of view can be the ultrasound wave that horizontal direction reflects, and can be also the ultrasound wave that level of incline direction 60 ultrasound wave reflecting of spending or other angle reflections are returned.
Step S1053: the distance value S that obtains human eye and mobile device 10 by S=vt/2; Wherein v is 340m/s.
For example, if human eye is in A place when (A place is horizontal direction), mobile device 10 first, towards human eye A prescription to sending ultrasound wave, starts timing simultaneously; At A place, human eye goes back ultrasonic reflections, and mobile device 10 receives after the ultrasound wave that A place reflects, and finishes timing to obtain time t; Last mobile device 10 obtains the distance value S of human eye and mobile device 10 by S=vt/2.
As human eye (B place is level of incline direction α degree) when the B place, mobile device 10 first, towards human eye B prescription to sending ultrasound wave, starts timing simultaneously, and in addition, mobile device 10 also detects the angle [alpha] of human eye B place and horizontal direction simultaneously; At B place, human eye goes back ultrasonic reflections, and mobile device 10 receives after the ultrasound wave that B place reflects, and finishes timing to obtain time t; Last mobile device 10 obtains the distance value S of human eye and mobile device 10 by S=v × t × cos α/2.
Step S106: carry out corresponding strategies according to distance value, watch mobile device 10 so that obtain user in suitable distance.
Wherein, as shown in Figure 4, Fig. 4 is the sub-step flow process intention of the first embodiment of step S106 in Fig. 2, and this sub-step comprises:
Step S1061: whether judging distance value is less than predeterminable range value range.
In step S1061, predeterminable range value range is User Defined setting.
Step S1062: if judging distance value is less than distance range value, mobile device 10 points out user to regulate to watch the distance value of mobile device 10.
If judging distance value is greater than distance range value, mobile device 10 remains unchanged.For example, if predeterminable range value range is 30cm, in the time that distance value is less than 30cm, during as 10cm, it is excessively near that now user watches the distance value of mobile device 10, easily human eye is damaged, mobile device 10 points out user to regulate to watch the distance value of mobile device 10, so that user watches the distance value of mobile device 10 to be greater than 30cm.Wherein, mobile device 10 by mode of vibration, dim the brightness of mobile device 10 or point out user to regulate to watch the distance value of mobile device 10 to play interference tones mode, or cross and directly close voluntarily demonstration, the eye health custom of cultivating user with this when near when determining user.
It should be noted that, at some in particular cases, while for example browsing text, if mobile device 10 does not have the function of enlarge font, now user may need closely to browse, and if mobile device 10 is carried out corresponding strategies, can affect user's experience.For this kind of situation, the present invention can judge the content of current demonstration, for example judge the size of font, and determining font when too small, automatically skip corresponding strategies, certainly, if user crossing always closely watch and exceed 20 minutes, 30 minutes etc., again recover to carry out corresponding strategies; The present invention can also determine whether some application-specific APP etc., and carries out intelligent set.
Further, as shown in Figure 5, Fig. 5 is the sub-step flow process intention of the second embodiment of step S106 in Fig. 2, and this sub-step comprises:
Step S1063: obtain a presets list.
Wherein, in the presets list, be provided with degree of fatigue value and with the degree of fatigue value distance range value of human eye and mobile device 10 one to one.
Step S1064: obtain the distance range value that degree of fatigue is corresponding from the presets list.
Step S1065: whether judging distance value is less than distance range value.
Step S1066: if judging distance value is less than distance range value, mobile device 10 points out user to regulate to watch the distance value of mobile device 10.
