Possess in the electronic apparatus embodiment of touch screen function and the aerial touch controllable function of the present invention at the same time, two kinds of touch controllable functions can be enabled wherein a kind of and forbid another, also can enable two kinds simultaneously.
Certainly, aerial sensing apparatus 10 is also not limited to be have touch screen function equipment, can also be other the equipment without touch screen function, as long as can identify aerial touch information, and can carry out corresponding operating according to aerial touch information.
In present embodiment, the quantity of position transducer 102 is six, is primary importance sensor 102-1, second place sensor 102-2, the 3rd position transducer 102-3, the 4th position transducer 102-4, the 5th position transducer 102-5 and the 6th position transducer 102-6 respectively.
Wherein, four position transducers 102-1,102-2,102-4,102-5 are separately positioned on the position in four corners of screen, and two other position transducer 102-3,102-6 are separately positioned on the right and left of screen, as shown in Figure 1.Wherein, primary importance sensor 102-1 and second place sensor 102-2 with the vertical center line of screen for axis of symmetry is symmetrical, 3rd position transducer 102-3 and the 6th position transducer 102-6 with the vertical center line of screen for axis of symmetry is symmetrical, 4th position transducer 102-4 and the 5th position transducer 102-5 with the vertical center line of screen for axis of symmetry is symmetrical, by making six position transducers 102 be symmetrically distributed in around viewing area, aerial sensing apparatus 10 can be made more attractive in appearance.
Certainly, in other embodiments, as shown in Figure 2, six position transducers 102 also can be other positions being arranged on non-display area 101, and such as primary importance sensor 102-1 is arranged in the non-display area of screen top; Second place sensor 102-2 and the 3rd position transducer 102-3 is positioned at the non-display area 101 on the right of screen, and with the cross central line of aerial sensing apparatus 10 screen for axis of symmetry is symmetrical; 4th position transducer 102-4 is positioned at the following non-display area of screen 101; 5th position transducer 102-5 and the 6th position transducer 102-6 is positioned at the non-display area 101 on the screen left side, and with the cross central line of aerial sensing apparatus 10 screen for axis of symmetry is symmetrical.
Continue to consult Fig. 1, in Fig. 1, the region of six dotted portions represents the induction range of each position transducer 102 respectively, the induction range of each position transducer 102 at least covers 1/6th aerial sensing apparatus 10, primary importance sensor 102-1 covers the upper left edge regions of aerial sensing apparatus 10, the induction range of the 6th position transducer 102-6 covers the centre on aerial sensing apparatus 10 left side, the induction range of the 5th position transducer 102-5 covers the left lower side region of aerial sensing apparatus 10, the induction range of second place sensor 102-2 covers the top right-hand side region of aerial sensing apparatus 10, the induction range of the 3rd position transducer 102-3 covers the zone line on the right of aerial sensing apparatus 10, the induction range of the 4th position transducer 102-4 covers the bottom right edge regions of aerial sensing apparatus 10.According to the size of the induction range of position transducer 102, by arranging each position transducer 102 in the position of non-display area 101, whole aerial sensing apparatus 10 screen can be made all to be in the induction range of position transducer 102.When user carries out aerial touch control operation by finger to aerial sensing apparatus 10, normally aloft sensing apparatus 10 place induction region operates, and aerial sensing apparatus 10 is in the induction range of position transducer 102, therefore can ensure that position transducer 102 can sense the aerial touch control operation of user.
Wherein, the aerial touch information of present embodiment refers to the screen coordinate value of the screen coordinate system of relatively aerial sensing apparatus 10 screen of touch point.For touch-screen, touch function normally realizes by obtaining the touching medium coordinate figure of touch points on screen on the touchscreen, and in present embodiment, because user's finger does not touch the screen of aerial sensing apparatus 10, but operate with aerial touch control manner, namely finger performs touch control operation aloft, responds to the screen coordinate value that aerial touch-control action obtains the touch point relative screen coordinate system pointed, and then obtain aerial touch information by position transducer 12.
Six position transducers 102 are specifically for obtaining the induction coordinate figure of the induction coordinate system of the touch point relative position sensor 102 above aloft sensing apparatus 10 screen itself, and this induction coordinate figure is the coordinate figure of touch point in the plane parallel with aerial sensing apparatus 10 screen.
Wherein, position transducer 102 is for having the sensor of sensor function and camera function, it comprises camera and infrared sensor, infrared sensor is used for detecting above screen, whether there is the finger of touching medium as user in real time, camera carries out when there is touching medium above infrared sensor detects screen making a video recording to obtain the image about touching medium, can analyze the image of touching medium thus, to obtain the touch point coordinate figure in the picture of touching medium, and then obtain the induction coordinate figure of induction coordinate system of touch point relative position sensor 102.Such as, when touching medium is for finger, touch point is generally the fingertip area of finger, therefore the predeterminable characteristic information characterizing the fingertip area of finger, by analyzing image after obtaining the image about finger, to find the image information matched with the characteristic information of the fingertip area preset, namely the position of image section in whole image frame corresponding to this image information be touch point position in the picture, can touch point be determined thus, and then touch point coordinate figure in the picture can be obtained.
Wherein, each position transducer 102 has itself induction coordinate system, the reference point of the induction coordinate system of each position transducer 102 may not be identical, and the induction coordinate figure that therefore each position transducer 102 obtains is the induction coordinate system of this position transducer 102 relatively itself.
The induction coordinate figure that controller 104 obtains for the load position sensor 102 that circulates.As shown in Figure 1, the induction range of each position transducer 102 is only cover the aerial sensing apparatus 10 of part, therefore be not the touching medium that each position transducer 102 can both sense above screen, namely, when user carries out aerial touch control operation above screen, at some time, not each position transducer 102 can both obtain the induction coordinate figure of touch point itself induction coordinate system relative.In addition, may overlap be there is in the induction range of six position transducers 102, namely when user carries out aerial touch control operation, may two, three or more position transducers 102 can sense touching medium simultaneously, also namely may two, three or more position transducer 102 all obtains induction coordinate figure.
Therefore, when controller 104 only reads the induction coordinate figure that a position transducer 102 obtains, such as shown in Figure 1, touch point A is only positioned at the induction range at primary importance sensor 102-1 place, namely now aerial touch control operation is only in the induction range of primary importance sensor 102-1, other position transducer 102-2, 102-3, 102-4, 102-5, 102-6 cannot sense aerial touch control operation, therefore be only that primary importance sensor 102-1 detection has sensed data, be the induction coordinate figure (x1 of touch point A, y1), this Time Controller 104 only reads the induction coordinate figure (x1 of primary importance sensor 102-1, y1), and according to the induction coordinate figure (x1 read, y1) screen coordinate value of the screen coordinate system of relatively aerial sensing apparatus 10 screen of touch point A is calculated.Controller 104, also for operating according to the screen coordinate value as aerial touch information, realizes the aerial operation of aerial sensing apparatus 10 thus, the operation namely not needing touching medium to touch screen can to realize operating equipment 12.
When controller 104 reads the induction coordinate figure that plural position transducer 102 obtains respectively, such as shown in Figure 1, touch point B is positioned at the overlapping region of the induction range of the 3rd position transducer 102-3 and the 4th position transducer 102-4, now the induction coordinate figure of the induction coordinate system of the relative 3rd position transducer 102-3 of touch point B of the 3rd position transducer 102-3 acquisition is (x3, y3), the induction coordinate figure of the induction coordinate system of the relative 4th position transducer 102-4 of touch point B that the 4th position transducer 102-4 obtains is (x4, y4).Controller 104 reads the induction coordinate figure (x3 of two position transducers 102-3,102-4, y3), (x4, y4) time, the induction coordinate figure that the position transducer choosing intended level according to the priority level of two position transducers 102-3,102-4 obtains, and the screen coordinate value calculating the screen coordinate system of relatively aerial sensing apparatus 10 screen of touch point B according to the induction coordinate figure that the position transducer of intended level obtains.Controller 104, also for operating according to the screen coordinate value as aerial touch information, realizes the aerial operation of aerial sensing apparatus 10 thus.
Further, in present embodiment, the priority level of six position transducers 102 is followed successively by primary importance sensor 102-1, second place sensor 102-2, the 3rd position transducer 102-3, the 4th position transducer 102-4, the 5th position transducer 102-5 and the 6th position transducer 102-6 from high in the end.Controller 104 is when reading the induction coordinate figure that at least two position transducers 102 obtain respectively, and the induction coordinate figure can choosing the position transducer of highest level corresponding carries out calculating screen coordinate value.Therefore, in above-mentioned situation, controller 104 is reading the induction coordinate figure (x3 of the 3rd sensor 102-3 and four-sensor 102-4, y3), (x4, y4) time, according to the rank of the 3rd sensor 102-3 and four-sensor 102-4 height, the induction coordinate figure (x3, y3) choosing the 3rd sensor 102-3 as effective coordinate figure to calculate the screen coordinate value of the screen coordinate system of relatively aerial sensing apparatus 10 screen of touch point B.Certainly, the priority level order of six position transducers 102 also can be other arrangement mode, as being followed successively by primary importance sensor 102-1, the 6th position transducer 102-6, the 3rd position transducer 102-3, the 4th position transducer 102-4, the 5th position transducer 102-5, second place sensor 102-2 from high to low.In addition, intended level also can be minimum rank, also can not first intended level, and judges voluntarily in practical operation or pre-conditionedly to select according to other, does not limit this.
Above-mentioned is only illustrate the situation that controller 104 reads the induction coordinate figure of two position transducers 102, for the situation of three or more, can choose one of them induction coordinate figure and calculate, do not repeat one by one at this according to same principle.
Further, the induction coordinate figure read, specifically for the mapping relations between the induction coordinate system of the position transducer corresponding to the induction coordinate figure that reads and the screen coordinate system of aerial sensing apparatus 10 screen, is converted to the screen coordinate value of the screen coordinate system of relatively aerial sensing apparatus 10 screen of touch point by controller 104.Specifically, when controller 104 only reads the induction coordinate figure of position transducer 102 correspondence, such as only read the induction coordinate figure (x1 of primary importance sensor 102-1, y1), now according to the mapping relations between the induction coordinate system of primary importance sensor 102-1 and the screen coordinate system of aerial sensing apparatus 10, the screen coordinate value that coordinate figure (x1, y1) is converted into the screen coordinate system of aerial sensing apparatus 10 will be responded to, when controller 104 reads the induction coordinate figure of plural position transducer 102 correspondence, such as read the induction coordinate figure (x3 of the 3rd sensor 102-3 and four-sensor 102-4, y3), (x4, y4), when choosing the induction coordinate figure (x3 of the 3rd sensor 102-3, y3) time as effective coordinate figure, now according to the mapping relations between the induction coordinate system of the 3rd position transducer 102-3 and the screen coordinate system of aerial sensing apparatus 10, coordinate figure (x3 will be responded to, y3) screen coordinate value of the screen coordinate system of aerial sensing apparatus 10 is converted into.
Wherein, the induction coordinate system of different its correspondences of position transducer may be not identical yet, therefore the mapping relations between the induction coordinate system of its correspondence of position transducer of different model or performance and the screen coordinate system of aerial sensing apparatus 10 screen also may not be identical, and same position sensor is not identical in the position of non-display area 101, its induction coordinate system may be not identical with the mapping relations between screen coordinate system yet, therefore, position transducer and it is after the position of non-display area 101 is determined, mapping relations between the induction coordinate system of position transducer and the screen coordinate system of aerial sensing apparatus 10 screen are also just determined, the mapping relations that therefore can obtain between the induction coordinate system of position transducer and the screen coordinate system of aerial sensing apparatus 10 screen according to the position of the relatively aerial sensing apparatus 10 of the characteristic of position transducer self and position transducer.
In order to induction coordinate figure and the concrete conversion method of screen coordinate value are described, be described exemplifying two kinds of different mapping relations below.Wherein, be that example is described with the induction coordinate of primary importance sensor 102-1.
The first mapping relations: it should be noted that, touch point is positioned at above screen, therefore the induction coordinate of primary importance sensor 102-1 is parallel with screen and is arranged in the induction coordinate system of the plane above screen, and two coordinate systems are respectively and are arranged in two planes be parallel to each other.Primary importance sensor 102-1 is after the position of non-display area 101 is determined, the true origin C of induction coordinate system also just determines.As shown in Figure 3, when the induction coordinate system of primary importance sensor 102-1 is all identical with the proportionate relationship of the screen coordinate system of aerial sensing apparatus 10 screen, the scale unit of the such as horizontal ordinate of primary importance sensor 102-1 is 1, the scale unit of ordinate is 2, then the scale unit of the horizontal ordinate of screen coordinate system is also 1, the scale unit of ordinate is also 2, in addition, when the true origin D of the screen coordinate system of vertical projection in the plane at screen place of the true origin C of the induction coordinate system of primary importance sensor 102-1 and screen does not overlap, according to the relation responded between the proportionate relationship of coordinate system and the proportionate relationship of screen coordinate system (namely both proportionate relationships are identical), and the position at the induction true origin C position of coordinate system and the true origin D place of screen coordinate system, can obtain the mapping relations responded between coordinate system and screen coordinate system is: (x, y)=(x1-dx, y1-dy), wherein, (x, y) be the screen coordinate value of touch point E relative screen coordinate system, (x1, y1) be the induction coordinate figure of touch point E relative induction coordinate system, dx be by true origin C vertical projection when the plane at screen place, true origin C and true origin D distance value in the direction of the x axis, dy be by true origin C vertical projection when the plane at screen place, true origin C and true origin D distance value in the y-axis direction.Thus, the mapping relations between the induction coordinate system of primary importance sensor 102-1 and the screen coordinate system of aerial sensing apparatus 10 screen can be obtained, when induction coordinate figure corresponding to primary importance sensor 102-1 chosen by controller 104, can convert according to above-mentioned mapping relations and obtain screen coordinate value.
The second mapping relations: as shown in Figure 4, when the induction coordinate system of primary importance sensor 102-1 is not identical with the proportionate relationship of the screen coordinate system of aerial sensing apparatus 10 screen, the ratio of the horizontal ordinate scale unit in both coordinate systems is fx, the ratio of ordinate scale unit is fy, the scale unit of the such as horizontal ordinate of primary importance sensor 102-1 is 1, the scale unit of ordinate is also 1, and the least unit of the horizontal ordinate of screen coordinate system is 1, the least unit of ordinate is also 1, and now fx and fy is 1; And when the true origin D of the screen coordinate system of vertical projection in the plane at screen place of the true origin C of the induction coordinate system of primary importance sensor 102-1 and screen coincides, namely reference point is equivalent to identical, now, according to the ratio relation of scale unit of induction coordinate system and screen coordinate system, can obtain the mapping relations responded between coordinate system and screen coordinate system is: (x, y)=(x1/fx, y1/fy).When induction coordinate figure corresponding to primary importance sensor 102-1 chosen by controller 104, can convert according to above-mentioned mapping relations and obtain screen coordinate value.The above-mentioned mapping relations only illustrating two kinds of situations, the mapping relations for other situations can obtain according to the principle of similitude, do not enumerate this.
No matter be the first above-mentioned mapping relations or the second mapping relations, the situation of existence two kinds or more mapping relations even simultaneously, touch point can be limited to the screen ranges of aerial sensing apparatus 10, namely, touch point above the screen orthogonal projection being defined in aerial sensing apparatus 10 is only effective touch point, it is invalid that periphery touch control operation outside above the screen orthogonal projection exceeding aerial sensing apparatus 10 is defined as, now for user, touch-control scope is in the plane the same with conventional touch screen;
Certainly, though also can define exceed aerial sensing apparatus 10 screen orthogonal projection above, its touch point is also effective, in this case, is divided into again two aspects:
1) without mapping relations between the screen of the touch point outside above the screen orthogonal projection being defined in aerial sensing apparatus 10 and aerial sensing apparatus 10, but auxiliary control can be carried out, such as once perceive touch point and move to outside above screen orthogonal projection above screen orthogonal projection, namely carry out the operations such as page turning;
2) unified mapping relations are formed between the touch point outside above the screen orthogonal projection being defined in aerial sensing apparatus 10 and above screen orthogonal projection and the screen of aerial sensing apparatus 10, even if operate outside now above screen orthogonal projection, the screen of aloft sensing apparatus 10 also can show its operation vestige, respond corresponding screen touch command, facilitate user to carry out exceeding the aerial touch-control of screen size on a large scale.
In addition, for different position transducers, the induction coordinate figure that it detects also can by the impact of the distance value between touch point and screen, namely the height of finger touch point distance screen is different, the induction abscissa value of the touch point relative induction coordinate system obtained also can slightly difference, therefore, in order to make detected induction coordinate figure more accurate, position transducer 102 can also detect the distance of touch point to screen, to determine according to this distance to respond to abscissa value, such as according to the errors table between the distance preset and horizontal ordinate, coordinate figure is revised, to improve accuracy.
Wherein, the aerial touch control operation of user to aerial sensing apparatus 10 can be the operation of aerial sliding cursor of mouse or aerial sliding unlocking operation etc.
Such as, when moving above the screen pointing sensing apparatus 10 aloft, position transducer 102 constantly obtains the multiple induction coordinate figures of finger touch point in moving process, controller 104 calculates multiple corresponding screen coordinate value according to effective induction coordinate figure, aerial sensing apparatus 10 makes the cursor of mouse of aerial sensing apparatus 10 move according to the track be made up of multiple screen coordinate value according to multiple screen coordinate value, thus can realize the operation dragging cursor of mouse in the air.
And for example, when realizing the slip unlocking operation of aerial sensing apparatus 10, aerial sensing apparatus 10, according to received screen coordinate value, obtains pointing the curve slided aloft.By the curve of default unblock, the curve obtained and default curve are contrasted, when two curve similarities are not less than a threshold value such as 80% or 90%, then think that the manipulation operation of user is unlocking operation, now aerial sensing apparatus 10 performs unlocking function.
In addition, in other embodiments, also can not convert according to the mapping relations between induction coordinate system and screen coordinate system and obtain the screen coordinate value of the screen coordinate system of touch point relative screen, such as can according to the position of the relatively aerial sensing apparatus of position transducer, and the distance between touch point and position transducer calculates this screen coordinate value.
