Detailed Description

The following describes in detail a specific embodiment of the sharing request identification method and the sharing request identification system applied to the selected object according to the present invention with reference to fig. 1 to 6. In this example, the current sharing device initiating the sharing is a mobile terminal with a touch screen, such as a PAD or other tablet computer, a laptop computer, a mobile phone, and the like. The sharing device also includes a pointing device with wireless interconnection function, i.e. a wireless terminal with relatively fixed position, such as desktop computer, tv, printer, wireless router, or a device for positioning function only, such as micro base station, signal transmitter, etc.

The present invention will be described below by taking a PAD initiating a file transfer to a computer as an example. As shown in fig. 1, comprising the steps of:

step S10: when the PAD enters the wireless network, the PAD establishes wireless connection with the pointing device. The pointing device obtains the model number of the PAD, assigns an IP address to the PAD and provides the IP address to the PAD. The pointing device stores the model number and IP address of the PAD in its list of attributes.

The fixed-point equipment is stored with an attribute list of all sharing equipment wirelessly connected with the fixed-point equipment, and the attribute list is stored with the model number, the equipment icon, the IP address and the space coordinate of the sharing equipment and the space coordinate of the fixed-point equipment. Wherein, when the PAD position changes, the attribute list is updated according to the space coordinate.

The establishment of the wireless connection is a well-known technique, and therefore, the process of establishing the wireless connection is not described in detail.

Step S20: and measuring the space coordinates of the PAD by taking the space coordinates of the pointing device as a reference, adding the space coordinates to an attribute list corresponding to the PAD stored by the pointing device, and sharing the attribute list with all sharing devices in the network so that the space coordinates of all the sharing devices in the network are known by other devices.

The coordinates of the pointing device are relatively fixed, so the PAD space coordinates are measured and calculated with the pointing device as a reference. As shown in fig. 2, the step of estimating the spatial coordinates of the PAD comprises:

step S201: the distances of at least three pointing devices to the PAD are calculated.

As shown in fig. 3In this embodiment, the spatial coordinates of three pointing devices are a (Xa, Ya, Za), b (Xb, Yb, Zb), and c (Xc, Yc, Zc), and wireless transceiver modules such as infrared, bluetooth, WIFI, or ultrasonic are installed on the three pointing devices. Correspondingly, the PAD is also provided with a corresponding wireless transceiver module. The distance of the Signal transmission can be calculated according to the attenuation degree of the wireless Signal transmission, for example, according to the Received Signal Strength Indicator (RSSI) formula P_R＝P_T/SⁿThe distances S between the three pointing devices and the PAD can be calculated respectively_a、S_bAnd S_c. Wherein, P_RIndicating the received power, P, of the radio signal at the receiving side_TThe transmitting power of the wireless signal of the sender is represented, S represents the distance between the wireless signal receiving and transmitting devices, n is a propagation factor, and the value of n in the air can be 3.

Step S202: and calculating the space coordinate of the PAD according to the result and the space coordinates of the three pointing devices.

Assuming that the spatial coordinates of the PAD are (X, Y, Z), the following equations can be derived according to the projection and pythagorean theorem:

$S_a=\sqrt{{(X-X_a)}^2+{(Y-Y_a)}^2+{(Z-Z_a)}^2},$

$S_b=\sqrt{{(X-X_b)}^2+{(Y-Y_b)}^2+{(Z-Z_b)}^2},$ and

$S_c=\sqrt{{(X-X_C)}^2+{(Y-Y_C)}^2+{(Z-Z_C)}^2}.$

from the three sets of calculations, the spatial coordinates (X, Y, Z) of the PAD are derived as: $\left\{\begin{array}{c}x=\frac{\mathrm{dx}}{d}\\ y=\frac{\mathrm{dy}}{d}\\ z=\frac{\mathrm{dz}}{d}\end{array}\right..$ wherein, $d=\left|\begin{array}{ccc}{c}_{11}& c_{12}& c_{13}\\ c_{21}& c_{22}& c_{23}\\ c_{31}& c_{32}& c_{33}\end{array}\right|;$

$\mathrm{dx}=\left|\begin{array}{ccc}{A}_1& c_{12}& c_{13}\\ A_2& c_{22}& c_{23}\\ A_3& c_{32}& c_{33}\end{array}\right|;$

$\mathrm{dy}=\left|\begin{array}{ccc}{c}_{11}& A_1& c_{13}\\ c_{21}& A_2& c_{23}\\ c_{31}& A_3& c_{33}\end{array}\right|;$

$\mathrm{dz}=\left|\begin{array}{ccc}{c}_{11}& c_{12}& A_1\\ c_{21}& c_{22}& A_2\\ c_{31}& A_{32}& A_3\end{array}\right|;$

$\left\{\begin{array}{c}{A}_1={S_b}^2-{S_a}^2-{{\mathrm{<figure-callout\; id="11"\; label="c"\; filenames="HDA0000137119830000032.png"\; state="\{\{state\}\}">c</figure-callout>}}_{11}}^2-{{\mathrm{<figure-callout\; id="12"\; label="c"\; filenames="HDA0000137119830000032.png"\; state="\{\{state\}\}">c</figure-callout>}}_{12}}^2-{{\mathrm{<figure-callout\; id="13"\; label="c"\; filenames="HDA0000137119830000032.png"\; state="\{\{state\}\}">c</figure-callout>}}_{13}}^2\\ {\mathrm{<figure-callout\; id="2"\; label="A"\; filenames="HDA0000137119830000031.png"\; state="\{\{state\}\}">A</figure-callout>}}_2={S_c}^2-{S_b}^2-{c_{21}}^2-{c_{22}}^2-{c_{21}}^2\\ A_3={S_a}^2-{S_c}^2-{c_{31}}^2-{c_{32}}^2-{c_{33}}^2\end{array}\right.;$

$\left|\begin{array}{ccc}{c}_{11}& c_{12}& c_{13}\\ c_{21}& c_{22}& c_{23}\\ c_{31}& c_{32}& c_{33}\end{array}\right|=\left|\begin{array}{ccc}{x}_a-x_b& y_a-y_b& z_a-z_b\\ x_b-x_c& y_b-y_c& z_b-z_c\\ x_c-x_a& y_c-y_a& z_c-z_a\end{array}\right|.$

the calculation of this step can be performed by the PAD or by the pointing device, and the parameters required for calculating the signal transmission distance and the parameters required for calculating the PAD spatial coordinates can be interacted with via a previously established wireless connection.

The calculation of the coordinates of the PAD can also be performed by other positioning techniques, such as a camera arranged on the roof or at a higher position acquiring a global image comprising the pointing device and the PAD, and positioning by image analysis of the PAD position. In addition, the projection of each sharing device of the horizontal projection can be obtained through the picture acquired by one camera, and the space coordinate of the PAD can be calculated through two or more cameras.

Step 203: and adding the spatial coordinates to an attribute list corresponding to the PAD stored by the pointing device, and sharing the attribute list with all sharing devices in the network, so that the spatial coordinates of all the sharing devices in the network are known by other devices.

Step S30: and determining the horizontal plane direction of each other sharing device relative to the PAD by taking the PAD as the center according to the horizontal plane coordinates of each other sharing device in the network relative to the PAD.

Wherein, be provided with direction sensor on this PAD, like geomagnetic sensor, the relative earth magnetism of the space direction of other each shared equipment of confirming is unchangeable to, no matter how this PAD rotates the screen in the horizontal plane, because direction sensor's existence, this PAD all can correctly mark out the direction of other each shared equipment.

As shown in fig. 3, the PAD space coordinates are used as the origin, and the space coordinates of other sharing devices relative to the PAD are obtained through coordinate transformation, and a direction is set as a reference direction, such as the north direction. And then determining the angle of each sharing device in the horizontal plane by taking the PAD as the origin according to the obtained space coordinate.

Wherein, when the space coordinates of each sharing device are converted into the coordinate systemWith the space coordinates (X, Y, Z) of the PAD as the origin, the space coordinates are (X)₁，Y₁，Z₁) Has a coordinate (X) after being transformed relative to the PAD₁’，Y₁’，Z₁') wherein, X₁’＝X₁-X；Y₁’＝Y₁-Y；Z₁’＝Z₁-Z, and the angle can be calculated from the coordinates and the trigonometric function.

It can be seen that the above-mentioned spatial coordinates and the angle calculated therefrom are independent of the PAD orientation, that is, when the PAD is rotated by the horizontal plane, the PAD is always positioned with reference to the spatial coordinates when being positioned for each shared device, that is, the PAD is not changed with the rotation of the PAD screen, so that when the selected object is subsequently determined by the finger on the PAD straight-line touch trajectory, the shared device is selected when the straight-line touch trajectory always points to the shared device as the selected object regardless of the placement of the PAD screen.

In addition, for the calculation of the angle, the calculation of the angle may be performed by projecting each of the sharing devices onto a horizontal plane, and a touch trajectory of the user on the PAD, which will be described later, may also be projected onto the horizontal plane.

Step S40: the user's finger slides on the PAD touch screen in a straight line, and the direction sensor is arranged in the PAD, so that the direction pointed by the projection of the straight line touch track of the user on the horizontal plane can be determined according to the reference direction calibrated by the direction sensor (the pitch angle of the PAD relative to the horizontal plane can be determined by the gravity sensor arranged in the PAD, and the projection of the horizontal plane can be determined, which is a known technology, and therefore, the technology is not described again.

Step S50: and on the horizontal plane of the projection, taking the sharing device matched with the direction pointed by the determined touch track as the sharing device selected by the user, namely the selected object, and transmitting the file to the selected sharing object.

For example, a user clicks a file displayed on the PAD (indicating that the file is selected) and keeps a touch state, and then quickly slides a finger towards the computer, so that the PAD determines the computer in the direction as a selected object according to the direction pointed by the touch track of the quickly sliding finger, and sends the file to the computer. In order to distinguish whether the sliding finger corresponds to moving a file in the PAD or sending the file outwards, the speed of the sliding finger can be set, and when a certain speed is reached (namely the quick sliding finger), the selected file is considered to be sent outwards, otherwise, the selected file is only considered to be the file moved and selected in the PAD.

In addition, when the user clicks a file and keeps a touch state, the icons of the sharing devices are respectively displayed on the PAD touch screen at the positions of the calculated angles, so that the user can conveniently visualize the operation, when the user displays the icons, the clicked file can be used as the center, and the sharing devices are displayed around the file by combining the angles, preferably around the PAD screen. When the touch sliding is carried out, the sliding direction is determined according to the sliding track, the icons of the sharing devices in other directions are hidden, only the icon of the sharing device in the direction is reserved, and after the touch sliding is finished, the displayed icon of each sharing device is hidden.

When more than two sharing devices exist at the same angle, the distance between the touch trajectory and the PAD is further calculated according to the coordinates (or the horizontal plane projection coordinates) of each sharing device, and the length value of the touch trajectory (namely the distance between the touch trajectory ending endpoint and the starting endpoint) is used for determining the sharing devices with different distances corresponding to different length values. At this time, if the sharing devices at the same angle are displayed, different icons are displayed at different positions corresponding to the different length values, so that the user operation is facilitated.

In addition, in order to increase fault tolerance, the touch trajectory may have a certain angle deviation, and the angle deviation may be adjusted according to the size of the angle formed by the shared devices in the adjacent directions. As shown in fig. 4, in the PAD screen, the point M is a clicked file, the adjacent angle between the IPAD and the tv direction is large, the angle deviation is set to be large, the adjacent angle between the computer and the mobile phone is small, the angle deviation is set to be small, or the shared device in the direction adjacent to and closest to the direction pointed by the touch trajectory is used as the selected object. In order to improve the selection accuracy, different lengths of the touch tracks are further set according to the distances from the computer and the mobile phone to the PAD, that is, when the end point (i.e., the termination contact) of the touch track with the M as the starting point is an arc line a or any point nearby, the selected object is represented as the computer, and when the end point is an arc line B or any point nearby, the selected object is represented as the mobile phone.

Or two distances between the touch track end point and the computer and mobile phone icon displayed on the PAD may be calculated, and the shortest distance is selected as the selected object, as shown in fig. 5, which is an enlarged schematic view of the section 2 in fig. 4, the distance from the touch track end point N at the center point of the computer icon is d2, the distance from the center point of the mobile phone icon to N is d1, as shown in the figure, d2 < d1, and therefore, the computer icon is selected.

In addition, it should be noted that, when there are a plurality of icons having the same or similar distances from the touch trajectory end point N, the user needs to manually select the icon to increase the accuracy of selection. Specifically, a distance threshold is preset, and if 2 or more than 2 icons are equal to or less than the threshold, the PAD pops up the dialog menu, displays the icon with the distance less than the threshold, and selects the icon by touching the icon by the user.

The following describes a recognition system for recognizing a selected object applied to multi-screen sharing, and as shown in fig. 6, the recognition system includes:

and a spatial coordinate receiving unit 11, configured to receive the spatial coordinates of the current sharing device and other sharing devices measured by the pointing device.

And the coordinate system conversion unit 12 is connected to the spatial coordinate receiving unit 11, and is configured to perform coordinate system conversion on the spatial coordinates of the other sharing devices with the spatial coordinates of the current sharing device as an origin to determine the direction and distance of the other sharing devices in the horizontal plane relative to the current sharing device.

And the storage unit 18 is connected with the coordinate system conversion unit 12 and is used for storing the space coordinates of all the shared devices after conversion.

In addition, the storage unit 18 is also used for storing the models, device icons and IP addresses of all shared devices.

Specifically, the determined spatial direction and the user touch trajectory of each of the other sharing devices are relatively unchanged from the geomagnetism, regardless of how the current sharing device rotates the screen in the horizontal plane.

And the shared device identification unit 16 is connected with the projection unit 13 and the touch track acquisition unit 14, and is used for determining a shared device matched with the length of the touch track in the direction indicated by the touch track.

The shared device identifying unit 16 includes a touch speed determining module, a touch trajectory fault-tolerant module, and a touch trajectory calculating module (not shown).

The touch speed judging module is used for judging the touch sliding speed of the user. Specifically, the other sharing devices are considered to be selected only when the touch sliding speed reaches a preset speed, and the starting point of the touch track corresponds to the selected file.

The touch track fault-tolerant module is used for correcting the angle of the touch track. Specifically, if the touch trajectory is angularly offset from the sharing device, the matching sharing device is considered when the end point of the touch trajectory is any point on the arc.

When more than two sharing devices exist at the same angle, the touch track calculation module is used for calculating the length of the touch track, and matching is carried out according to the sharing devices at different positions corresponding to different length values.
