In addition, term "and/or" herein, being only a kind of incidence relation describing affiliated partner, can there are three kinds of relations in expression, and such as, A and/or B, can represent: individualism A, exists A and B simultaneously, these three kinds of situations of individualism B.In addition, character "/" herein, when not illustrating, general expression forward-backward correlation is to the relation liking a kind of "or".
In the embodiment of the present invention, electronic equipment can refer to the electronic equipment that mobile phone, panel computer (PAD), notebook computer etc. are different, for described electronic equipment specifically which type of equipment the present invention do not limit, as long as described electronic equipment can detect the distance between barrier.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
Refer to Fig. 1, the embodiment of the present invention provides a kind of information processing method, and the method can be applied to electronic equipment, that is, in the method, the executive agent of each step can be electronic equipment.The flow process of the method is described below.
Step 101: the distance between the display unit of detected electrons equipment and barrier is the first distance.
In specific implementation process, it can be the distance by being arranged between range sensor detected electrons equipment in electronic equipment and barrier, and for the ease of practical application, range sensor is generally positioned at the front (i.e. the face at the display unit place of electronic equipment) of electronic equipment.Such as, be mobile phone for electronic equipment, range sensor is generally positioned in the receiver both sides of mobile phone or the groove at receiver place.In addition, the type of sensor of adjusting the distance in the embodiment of the present invention does not do concrete restriction, as long as it can detect the distance between barrier.
Consider versatility, with comparatively conventional range sensor for example, the principle of its detecting distance is: by utilizing emitted light pulse, and measures this light pulse from being transmitted into the interval time reflected by barrier, then calculates the distance between barrier by this interval time.And in general, the light pulse that range sensor is launched has a coverage, and this coverage is the sensing range of this range sensor.
Such as refer to Fig. 2, the rectangle frame 201 of wherein filling with ater represents the side of the display unit of electronic equipment, with the ellipse representation range sensor that ater is filled, the scope that its light pulse coverage of launching covers for cone 200, namely, the scope that the sensing range of range sensor covers for cone 200, and the height of cone 200 needs to determine according to effective propagation distance of light pulse, the bottom surface radius of a circle of cone 200 needs to determine according to the characteristic of range sensor, namely, the sensing range of range sensor needs to be determined by the self-characteristic of range sensor.
In addition, for the ease of the description of further part, range sensor in the embodiment of the present invention is detected distance between barrier and can be detected by the light pulse represented by the dotted line 202 in such as Fig. 2, namely, detect with the light pulse of launching perpendicular to range sensor (namely perpendicular to the display unit of electronic equipment), that is, in embodiments of the present invention, first distance is that range sensor is detected by the light pulse of launching perpendicular to range sensor and between barrier distance, can think that the first distance is electronic equipment by the distance between actual that directly detect and the barrier of range sensor.And for other light pulse in sensing range, detect and can do similar process to the mode of the distance between barrier.
Step 102: determine the first angle; Wherein, the first angle is the angle between display unit and surface level.
When electronic equipment is in different attitudes, the angle between its display unit from surface level is generally different.Notebook computer for electronic equipment, when the display screen of notebook computer is relative with keyboard face be adjacent to closed time, now can think that the angle between display screen and surface level is 0 °, when display screen is perpendicular to keyboard face, now can think that the angle between display screen and surface level is 90 °, when display screen principle keyboard face and when being close to when the back side of display screen and desktop, now can think that the angle between display screen and surface level is 180 ° gradually, etc.
In specific implementation process, the execution sequence of step 101 and step 102 can be arbitrary, if the performance of electronic equipment meets the demands, step 101 and step 102 can also be carried out simultaneously.
In specific implementation process, corresponding mode can be selected to determine the first angle according to the different hardware configurations of electronic equipment, understand for the ease of reader, below enumerate two kinds of modes and be illustrated.
First kind of way:
Optionally, in an alternative embodiment of the invention, determine the first angle, comprising:
Detected electrons equipment is at the acceleration information in the first moment; Wherein, the first moment was the moment of detection first distance;
According to the acceleration information in the first moment, determine the first angle.
In the motion process of electronic equipment, can by being arranged at the history acceleration information of the acceleration transducer detected electrons equipment in electronic equipment, and preserve, that is, determine at the first this hardware configuration of acceleration transducer that used in the mode of the first angle in electronic equipment.
So, when the first angle determined by needs, electronic equipment can determine the acceleration information in the first moment according to history acceleration information, and the acceleration information in the first moment can show the instant motion state of electronic equipment when the first distance being detected.
Optionally, in an alternative embodiment of the invention, according to the acceleration information in the first moment, determine the first angle, comprising:
According to the acceleration information in the first moment, determine two acceleration component values of electronic equipment in the first moment; Wherein, two acceleration component values comprise the acceleration component values along the Z-direction in three dimensional coordinate space and X-direction, or two acceleration component values comprise the acceleration component values along the Z-direction in three dimensional coordinate space and Y-direction;
According to two acceleration component values, determine the first angle.
After the acceleration information in acquisition first moment, accekeration corresponding with it can be determined.
Because acceleration has directivity, in order to determine the occurrence of the first angle according to the accekeration in the first moment, the acceleration component values in three directions can be decomposed into by degree of will speed up, then calculate the occurrence of the first angle according to acceleration component values.In specific implementation process, a three-dimensional cartesian coordinate system first can be set, then according to arranging three-dimensional cartesian coordinate system, accekeration be decomposed, to obtain acceleration component values.It should be noted that, arranging of three-dimensional cartesian coordinate system can be arbitrary, as long as the acceleration component values that those skilled in the art can obtain according to decomposition determines the occurrence of the first angle, the present invention does not do concrete restriction.
Understand for the ease of reader, be illustrated with a kind of concrete set-up mode of three-dimensional cartesian coordinate system below.
Notebook computer for electronic equipment, refer to Fig. 3 A, using the right edge of the display unit of notebook computer (i.e. Panel) as three-dimensional cartesian coordinate system for Y-axis, and using in right edge away from the positive dirction of the direction of keyboard (i.e. Keyboard) as Y-axis, and X-axis and Z axis are respectively perpendicular to Y-axis, and the positive dirction of the positive dirction of X-axis and Z axis refers to shown in Fig. 3 A.
Again see Fig. 3 B, suppose that the angle between the display unit of notebook and surface level is β, and the accekeration in the first moment of hypothesis acquisition is a, so, obtaining the acceleration component values of a in Y-axis after being decomposed by a is a
y, the acceleration component values on Z axis is a
z, can in the hope of tan β=a according to geometric relationship
y/ a
z, so β=arctana
y/ a
z.
Similarly, also can obtain the acceleration component values of a in X-axis is a
x, and then again according to a
xand a
zcalculate β, concrete calculation procedure just repeats no more herein.
Due to versatility and the ubiquity of acceleration transducer, the versatility of first kind of way is also higher, that is, the custom hardware in electronic equipment can be utilized to configure and determine the first angle, the existing configuration of electronic equipment can be made full use of like this, improve the utilization factor of hardware.
And, in a practical situation, electronic equipment may be generally real time kinematics, and electronic equipment acceleration information at any time more accurately can be detected by acceleration transducer, the occurrence of the first angle is calculated again by acceleration component values, can improve the accuracy determined the first angle largely, the precision determined is higher.
The second way:
Optionally, in an alternative embodiment of the invention, determine the first angle, comprising:
The first angle is detected by the angular transducer of electronic equipment.
That is, this hardware configuration of angular transducer having used electronic equipment in the mode of the first angle is determined at the second.Specifically, can detect the first angle according to the self-characteristic of the angular transducer in electronic equipment, just repeat no more herein.
When electronic configurations has angular transducer, the occurrence of the first angle can be determined fast by the second way, the speed determined, the time of whole ranging process can be reduced as far as possible, raise the efficiency.
In implementation process, if electronic equipment was both configured with acceleration transducer, be configured with angular transducer again, the mode (mode that such as user is arranged is first kind of way) that can arrange according to user determines the first angle, and when user is arranged, electronic equipment can be selected to determine mode voluntarily, such as in order to obtain the higher determination result of precision, can first kind of way be adopted, or, in order to determine the first angle fast, the second way can be adopted, in addition, also can a kind of mode of Stochastic choice, etc.
Certainly, above-mentionedly just list two kinds of modes and be illustrated, the mode as other does not just schematically illustrate one by one, everyly can determine that the mode of the first angle all should within protection scope of the present invention.
Optionally, in an alternative embodiment of the invention, the distance between the display unit and barrier of detected electrons equipment be first distance afterwards, described method also comprises:
Determine that described barrier is human body;
Determine the first angle, comprising:
When described barrier is human body, determine described first angle.
In implementation process, electronic equipment detect and barrier between distance be generally in order to according to the distance measured for user provides certain to serve, such as, electronic equipment can according to the display effect of the distance adjustment display unit detected, so that for user provides good viewing effect, so, in order to avoid maloperation appears in electronic equipment, simultaneously also in order to reduce the processing load of electronic equipment as far as possible, detecting whether the between barrier first distance can also disturbance in judgement thing be human body afterwards, only just subsequent operation can be performed when determining that barrier is human body.
Such as, electronic equipment can gather the image information of barrier by image acquisition units, determine whether barrier is human body actually according to face recognition technology or human body recognition technology again, or, electronic equipment can also detect the temperature of barrier by infrared sensor, judge that whether the temperature detected is corresponding with the general temperature of human body again and determine that whether barrier is actually as human body, or other mode can also be had, be not just illustrated one by one herein.
Step 103: according to the first Distance geometry first angle, determine second distance.
Continuing for electronic equipment is notebook computer, refer to Fig. 4 A, with the ellipse representation range sensor of filled black, barrier is represented with the rectangle frame 400 of filled black, the first distance between the display unit detected by step 101 and barrier is L1, and the first angle between the display unit determined by step 101 and surface level is β.And in fact, distance nearest between barrier and display unit is L2, that is, there is bee-line L2 in barrier and display unit, in order to ensure that range measurement conforms to actual conditions as far as possible as far as possible, using L2 as the actual range between barrier and display unit, can compare with actual conditions like this and conform to.
According to above analysis, L2 is second distance, according to the first Distance geometry first angle determination second distance, is in fact exactly calculate L2 according to L1 and β, revises to obtain L2 by β to L1.
Specifically, optionally, in another embodiment of the present invention, according to the first Distance geometry first angle, determine second distance, comprising:
Determine second distance according to formula (1), formula (1) is: L2=L1*cos (90 ° of-A);
Wherein, L2 represents second distance, and L1 represents the first distance, and A represents the first angle.
After determining L1 and β, directly can calculate L2 according to formula (1).
Understand for the ease of reader, below derivation carried out to formula (1) and illustrate:
Refer to Fig. 4 B, derive according to geometry, can determine that the angle between L1 and L2 is 90 ° of-β, and according to the definition of cosine function, cos (90 ° of-β)=L2/L1, so can determine L2=L1*cos (90 ° of-β).
It should be noted that, the embodiment of the present invention just lists a kind of concrete account form obtaining L2, and those skilled in the art according to geometric knowledge, under the prerequisite not paying creative work, can also adopt other mode to calculate and obtain L2.
In addition, optionally, in an alternative embodiment of the invention, according to the first Distance geometry first angle, before determining second distance, described method also comprises:
Determine that the value of the first angle is not 90 degree.
When display unit is perpendicular to surface level, namely when the value of the first angle is 90 °, according to the characteristic of range sensor detecting distance, can determine to be now the same by the actual distance detected of range sensor with the actual range between display unit and barrier, now can using the actual distance detected directly as the actual range between display unit and barrier.So, determine can using the actual distance detected directly as actual range time, electronic equipment can be saved again according to the operation of the first Distance geometry first angle determination second distance, that is, in order to reduce nuisance operation that electronic equipment carries out and reduce the processing load of electronic equipment, in embodiments of the present invention, before according to the first Distance geometry first angle determination second distance, also need to judge whether the first angle is 90 °, only when determining out of plumb between display unit and surface level, just can perform the operation determining the first angle.
Step 104: second distance is defined as the actual range between display unit and barrier.
That is, the second distance obtained after revising the first distance according to the first angle could show the actual range between display unit and barrier as far as possible, first distance is revised, can reduce (even eliminate) due to the angle change of display unit causes the error produced of finding range as far as possible, and then the accuracy of range measurement can be improved, to improve the precision of range observation, realize precisely finding range.
Optionally, in an alternative embodiment of the invention, after second distance being defined as the actual range between display unit and barrier, described method also comprises:
According to the corresponding relation of distance with the value of display parameter, the value of the first display parameter of electronic equipment is adjusted to the value corresponding with second distance.
That is, after obtaining the actual range between display unit and barrier, electronic equipment according to the automatic adjustment of this actual range realization to the display display effect of display unit, to meet the actual viewing demand of user as far as possible, can strengthen the viewing experience of user.
Such as, when determining that second distance is 1.1 meters, the font size of display unit can be adjusted to No. two fonts by electronic equipment, when determining that second distance is 0.6 meter, font size can be adjusted to No. four fonts.
Again such as; when determining that second distance is 0.9 meter; the display brightness of display unit can be adjusted to 90 by electronic equipment; when determining that second distance is 2.3 meters; display brightness can be adjusted to 60; like this when user is in nearer position, the eyesight of user can be protected by reducing display brightness, and do not affect again the normal viewing of user.
Above-mentioned font size and display brightness all can be understood as the display parameter in the embodiment of the present invention, in specific implementation process, display parameter may be also other parameters, but principle and the process of adjustment are all similar with the adjustment of above-mentioned font size and display brightness, just repeat no longer one by one herein.
In the embodiment of the present invention, electronic equipment is when detecting that the distance between barrier is the first distance, also can according to the first angle determination second distance between the first Distance geometry display unit and surface level, finally using the second distance determined as the actual range between barrier, that is, in the inventive solutions, electronic equipment not using the first distance of directly detecting as the actual range between barrier, but on the basis of the first distance, by the first angle, corrected Calculation is carried out to obtain second distance to it, and using revised second distance as the actual range between barrier.
