    [0013] The basic idea of the present disclosure is: to carry out the materialization treatment in the process that the user moves the window object by means of a mouse or a finger, after the user finishes the dragging operation, to apply the inertial movement of an object in motion through the inertia processing unit according to linear speed and angular speed when a mouse drag button is released or the finger is lifted.
    [0014] The moving object in the present disclosure means an instance of the window object capable of responding to the mouse or dragging operation via the finger on the touchscreen, the window object has its own interface attribute, method attribute and data attribute , and can respond to the window interface trigger event. For example, taking the Windows operating system as an example, the window object can be a window for displaying contact information, and the window object has the function of responding to events by clicking and moving a user, and has interface attributes, such as width, height, angle of rotation with the center of the window, such as the center of a circle, horizontal coordinate (CenterX) of the center of the window, and vertical coordinate (CenterY) of the center of the window.
    [0015] To conveniently describe, in the following description, the operating scenario is that the user moves with his finger or a mouse, a window object instance (called below just a window object for short) that represents an IM contact; when moving the window object at a certain speed, the user raises his finger or releases the mouse button quickly, then the window object keeps moving and rotates along the original motion track by the force of inertia, and slowly returns to the static state by the frictional force (deceleration).
    [0016] In order to achieve and make the objective of the disclosure clearer, the technical solution and advantages of this disclosure are described below with reference to the accompanying drawings and their modalities are detailed.
    [0017] Figure 1 shows a structural diagram of a device for effecting the inertial motion of a window object according to the present disclosure, the device includes a touch point capture unit 101, a drag processing unit 102 and an inertia processing unit 103.
    [0018] The touch point capture unit 101 is configured to capture the operation that an input device drags a window object on a screen, and generates the corresponding control information.
    [0019] The input device includes a touch screen, mouse, WordPad and so on, which can perform the movement of the window.
    [0020] The control information includes: (1) initial control information, when the input device initially touches the window object, including the position, time, device number, identity that initially indicates the touch on the window object, and so on ; (2) current control information when the input device moves the window object, including the position, time, device number, identity that indicates dragging the window object, and so on; (3) launching the control information, when the input device releases the window object and ends up dragging the window object, including the position, device time, identification number indicating the release of the window object and so on .
    [0021] The touch point capture unit 101 is an interface unit between the device of the present disclosure and the operating system, which monitors the operation of the operating system on the window object in real time, obtains the control information generated by the input device , and sends the control information to the drag processing unit, which performs the effect of dragging the window object.
    [0022] For example, when the mouse is pressed and moved, or the finger presses and moves, the touch point capture unit 101 captures the event that the mouse is pressed or the touch of the finger, and sends the initial control information to the drag processing unit 102, where the initial control information includes: the touch point position coordinate, the current time, device number, the identity that indicates that the left mouse button is pressed or the touch of the fingers for preparing the dragging of the window object, and so on. The number of devices is used to distinguish between different input devices; under the condition of several touch points, for example, the user uses two fingers to touch the window object, the numbers of the devices corresponding to the fingers that come into contact with the touch screen at different times are different.
    [0023] The drag processing unit 102 is configured to carry out the drag effect of the window object according to the control information sent from the touch point capture unit 101.
    [0024] Trailing processing unit 102 includes: a first motion processing unit and an initial speed processing unit.
    [0025] The first motion processing unit is configured to start a first timer Timer1 when it receives the initial control information sent from the touch point capture unit 101, to obtain, according to the current control information sent from the point capture unit touch 101, the amount of displacement and the amount of rotation of the window object corresponding to the current period of Timer1, under the activation of Timer1, and send the obtained amount of displacement and the amount of rotation to the window object.
    [0026] The initial speed processing unit is configured to obtain the initial linear speed and initial angular speed after receiving the release control information sent from the touch point capture unit 101, and to send the initial linear speed and angular speed. obtained for the inertia processing unit.
    [0027] The method for carrying out the dragging effect of the window object is specifically: (1) after receiving the initial control information sent from the touch point capture unit 101, the drag processing unit 102 records the position coordinate information (X0, Y0) of the initial touch point, the contact time initial T0 and the device number; (2) when the mouse is moved after being pressed or the finger moves after pressing, the drag processing unit 102 records the position (Xi, Yi) of the mouse or finger, the current time Ti and the device number at each interval Δt, obtains the amount of displacement and the amount of rotation in relation to the time point of the previous record, and sends the relative amount of displacement and relative amount of rotation to the window object; and, then the window object defines its own attribute value to carry out the drag effect; for example, the attributes of the central coordinates of the window object are (CenterX, CenterY), and the rotation angle attribute is angle; when the current displacement quantity and the rotation quantity are obtained per window object during the period of Ti are (ΔΧ, ΔΥ) and a, respectively, the window object defines its own attribute value of the coordinate center and attribute value rotation angle as: CenterX = CenterX + ΔX, CenterY = CenterY + ΔY, Angle = Angle + α; the window object triggers its function of redefining the interface by defining the attribute value of the coordinate center and attribute value of the rotation angle, in order to display the window object in a new coordinate position and new rotation angle; (3) when the input device releases the window object, that is, when the mouse button is released or the fingers are lifted, The touch point capture unit 101 sends the release control information to the control unit. drag processing 102, the drag processing unit 102 obtains the initial linear speed and the initial angular speed according to the amount of displacement and the amount of rotation that are obtained during the last period of Timer1 before releasing;
    [0028] There are two cases, that is, in the case of a single touch point and the case of several touch points, in obtaining the amount of displacement, amount of rotation, initial linear speed and initial angular speed. (1) As shown in figure 2, in the case of a single touch point, the method for obtaining the amount of displacement, the amount of rotation, the initial linear speed and the initial angular speed includes: the amount of displacement between Ti-1 and Ti is: (ΔΧ, ΔΥ) = (Χi-Χi-1, Υi-Υi-1), where (Xi, Yi) is the coordinate vector of the touch point corresponding to the Ti period of Timer1, and (Χi-1, Υi-1) is the coordinate vector of the touch point corresponding to the Ti-1 period of Timer1; the amount of rotation between Ti-1 and Ti is: a = arcs [Ui. Vi / (| ui | vi |)]; where the center of rotation coordinates are the central coordinates of the window object: (Cx, Cy); ui is the vector between the coordinates of the touch point corresponding to the Ti period of Timer1 and the coordinates of the center of rotation, that is, ui = (Xi-Cx, Yi-Cy); Vi is the vector between the coordinates of the touch point corresponding to the Ti-1 period of Timer1 and the coordinates of the center of rotation, that is, Vi = (Xi-1-Cx, Yi-1-Cy); the initial linear velocity V when the input device releases the window object is: V = (Xn-Xn-1, Yn-Yn-1) / (Tn-Tn-1) = (Xn-Xn-1, Yn-Yn-1) / Δt, where (Χn, Yn) is the coordinate vector of the touch point corresponding to the last Tn period of Timer 1 when the input device releases the window object; (Xn-1, Yn-1) is the coordinate vector of the touch point corresponding to the Tn-1 period; If Δt is defined as a standard time unit, then the above equation can be simplified as: V = (Xn-Xn-1, Yn-Yn-1); the method for obtaining the initial angular velocity Va when the input device releases the window object is: Va = arcs [un. vn / | un | vn |)] / (Tn-Tn-1) = arcs [un. Vn / (| un | Vn |)] / Δt, where un is the vector between the coordinates of the touch point (Xn, Yn) corresponding to the Tn period of Timer1 and the coordinates of the center of rotation (Cx, Cy), that is, Un = (Xn-Cx, Yn-Cy) , and vn is the vector between the coordinates of the touch point corresponds to the Tn-1 period of Timer1 and the coordinates of the center of rotation, that is, vn = (Xn-1-Cx, Yn-1-Cy);
    [0029] If Δt is defined as a standard time unit, then the above equation can be simplified as: Va = arcs [un. Vn / (| un | vn |)]. 2) As shown in figure 3, in the case of several touch points, only two touch points with the smallest number of devices are taken into account, the method to obtain the amount of displacement, the amount of rotation, the initial linear speed and the initial angular velocity includes: assuming that the coordinates of two touch points with the least number of devices correspond to the Ti-1 period of Timer1 are (Xi-1, d0, Yi-1, d0) and (Xi-1, d1, Yi-1, d1 ), and the coordinates corresponding to the Ti period are (Xi, d0, Yi, d0) and (Xi, d1, Yi.d1), where dO and d1 are device numbers, so the coordinates of the center of the vectors of the two points of touch during Ti-1 period and Ti period are respectively: (CXi, CYi) = (((Xi, d0 + Xi, d1) / 2, (Yi, d0 + Yi, d1) / 2), (CXi-1, CYi-1) = (((Xi-1, d0 + Xi-1, d1) / 2, (Yi-1, d0 + Yi-1, d1) / 2); the amount of displacement between Ti-1 and Ti is: (ΔX, ΔY) = (CXi-CXi-1, CYi-CYi-1); when the input device releases the window object, the initial linear speed corresponding to Timer1's Tn period is: V = (CXn-CXn.1, CYn-CYn-1) / (Tn-Tn-1) = (CXn-CXn-1, CYn-CYn-1) / Δt, where (Xn, CYn) and (CXn-1, CYn-1) are the coordinates of the center of the vectors that are formed by two touch points with the least number of devices, respectively, during the last period Tn and the period Tn- 1 of Timer1 when the input device releases the window object; Δt is the time interval for Timer1;
    [0030] If Δt is defined as a standard time unit, then the above equation can be simplified as: V = (CXn-CXn-1, CYn-CYn-1); in the case of multiple touch points, when obtaining the amount of rotation, only two touch points with the least number of devices are taken into account, the point of intersection of a line connecting the two points during the Ti-1 period with a line connecting the two touch points during the Ti period serves as the center for obtaining the amount of rotation; the coordinates of two touch points corresponding to the Ti period are (Xi, d0.Yi, d0) and (Xj, d1, Yi, d1) ,, and the coordinates of two touch points corresponding to the Ti-1 period are (Xi -1, d0, Yi-1, d0) and (Xi-1, d1, Yi-1, d1); the central coordinate of rotation for obtaining the amount of rotation is: (Cx, Cy) = (Xi, d0 + Xi, d1) / 2, (Yi, d0 + Yi, d1) / 2); the amount of rotation between Ti-1 and Ti is: αi = arcs [ui. vi / (| ui | vi |)], ui where is the vector (Xi, d0-Xi, d1, Y, d0-Yi, d1) formed by the two touch points with the smallest number of devices corresponding to the Ti period of Timer1, vi is the vector (Xi-1, d0-Xi-1, d1, Yi-1, d0-Yi-1, d1) formed by the two touch points with the smallest number of devices corresponding to the Ti-1 period of Timer1.
    [0031] When the input device releases the window object, the initial angular velocity Va of the amount of rotation corresponding to the Tn period of Timer1 is: Va = arcs [un. Vn / (| Un | Vn |)] / (Tn-Tn-1) = arcs [un. Vn / (| Un | Vn |)] / Δt, where un is the vector (Xn, d0-Xn, d1, Yn, d0-Yn, d1) formed by the two touch points with the least number of devices corresponding to the last Tn period of Timer1 when the input device releases the object window, and vn is the vector ((Xn-1, d0-Xn-1, d1, Yn-1, d0-Yn-1, d1) formed by the two touch points with the smallest number of devices corresponding to the Ti- 1.
    [0032] If Δt is defined as the standard time unit, then the above equation can be simplified as: Va = arcs [un. Vn / (| un | vn |)].
    [0033] The inertia processing unit 103 is configured to carry out the effect of the inertia movement after the input device releases the window object, that is, after the user has finished the drag operation. After receiving the release control information sent from the drag processing unit 102, the inertia processing unit 103 starts a second timer Timer2 to activate a timer processing function at each time interval Tg, obtaining, according to the initial linear velocity and initial angular velocity corresponding to the current period of Timer2, the amount of displacement and the amount of rotation during the current period in the timer processing function, and then sends the obtained amount of displacement and the amount of rotation during the current period for the window object; then the window object defines its own attribute to obtain the effect of the inertial movement.
    [0034] The method for obtaining the initial linear velocity corresponding to the Ti period of Timer2 includes: Vi = Vi-1-Vdec * Tg, where Vdec is the deceleration of the linear speed, and can be predefined by a user or a system according to the current situation, which is equivalent to adjusting the friction coefficient of the linear speed; in a first period of Timer2 after the input device releases the window object, V1 is the initial linear speed V sent by the drag processing unit 102; Tg is the Timer2 period, and can be predefined by the user or by the system.
    [0035] The method for obtaining the initial angular velocity corresponding to the Ti period of Timer2 includes: Vai = Vai-1-Vadec * Tg, where Vadec is the deceleration of the angular velocity, and can be predefined by a user or a system according to the real situation, which is equivalent to adjusting the friction coefficient of the angular velocity, in a first period of Timer2 after the input device releasing the window object, Va1 is the initial angular velocity Va sent by the drag processing unit 102; the amount of displacement corresponding to the Ti period of Timer2 is: (ΔX, ΔY) = (Vi-Vdec * Tg) * Tg = (Vi.X-Vdec * Tg, Vi.Y-Vdec * Tg) * Tg, where Vi is the initial linear velocity vector corresponding to the Ti period of Timer2, and Tg is the time interval of Timer2; the amount of rotation corresponding to the Ti period of Timer2 is: αi = (Vai-Vadec * Tg) * Tg, where Vai is the initial angular velocity corresponding to the Ti period of Timer2;
    [0036] If Tg is equal to Δt, and Δt is defined as the standard time unit, then the above equation can be simplified as: (ΔX, ΔY) = (Vi.X-Vdec, Vi.Y-Vdec), αi = (Vai-Vadec), that is, if Tg = Δt serves as the time unit of the sampling speed, the processing of inertia and the updated position of the window object, then the amount of calculation can be greatly reduced.
    [0037] When the amount of displacement and the amount of rotation of the window object's inertia movement during the current period, which are obtained through the above equation, are less than or equal to 0, the inertia process ends.
    [0038] After receiving the amount of displacement and the amount of rotation sent by the inertia processing unit 103, the window object defines its own coordinate center attribute value and angle of rotation attribute value as: CenterX = CenterX + ΔX, CenterY = CenterY + ΔY, Angle = Angle + α.
    [0039] The function of resetting the interface is triggered by setting the attribute value of the coordinate center and the attribute value of the rotation angle, in order to display the window object in the new coordinate position and new rotation angle, thus realizing the effect of inertial motion.
    [0040] Figure 4 shows a flowchart of a method for moving a window object according to the present disclosure, including the following steps: Step 401: Monitor the operation of the initial touch operation of the input device, and obtain the initial control information.
    [0041] In the step, the initial touch operation of the input device is controlled by the touch point capture unit, and the touch point capture unit sends the initial control information to the drag processing unit, after detecting the operation initial touch.
    [0042] The input device comprises mouse, touch screen, wordpad and so on, which have the function of moving the window object. If the input devices are different, then the generated system messages are different. For example, the system message indicating that the mouse activates the window object to move it, it may be that the left mouse button is pressed and moves, the system message, indicating that the touch screen activates the object. window to move is that the fingers press and move. The initial touch operation refers to a click operation that a user initially presses the left mouse button, or the finger initially presses the touch screen to move the window object. The initial control information includes: the position of the initial touch point, time, device number, button code and so on.
    [0043] Step 402: record the initial control information, starting a first timer Timer1, establishing a time interval as Δt, where Δt is predefined by a user or a system according to the real situation.
    [0044] After receiving the initial control information sent from the touch point capture unit, the drag processing unit records the initial control information and starts Timer1. Timer1 is used to periodically trigger an event function to calculate the amount of displacement (ΔΧ, ΔY) and the amount of rotation α of the window object, in order to obtain the amount of displacement and the amount of rotation generated on the screen by the input device during the current period.
    [0045] Step 403: when the Timer1 time interval is longer, obtain the current control information, and obtain the amount of displacement and the amount of rotation generated on the screen by a user through the input device during the current period.
    [0046] The prerequisite for the execution of the step is that the user maintains the operation of pressing the input device, and immobilizes or drags the window object; the touch point capture unit transforms the monitored system message generated by the input device into current control information (including position, time, device number, and so on) and continuously sends current control information to the trawl processing unit, the trawl processing unit updates the current local cache control information in real time, and records the current control information when each Timer1 time interval forms a history of the control information, the history can reflect on the trace, which can also be called a gesture, of the movement of the input device on the screen, and then the amount of displacement and the amount of rotation of the window object corresponding to the current Tirnerl period are obtained.
    [0047] Step 404: the window object adjusts its position and the rotation angle on the screen according to the amount of displacement and the amount of rotation obtained.
    [0048] After obtaining the amount of displacement and amount of rotation at the current point in time, the drag processing unit sends these to the window object; the window object triggers a method of redefining the window, defining its own coordinate center and the value of the rotation angle attribute in relation to the coordinate center, in order to carry out the drag effect.
    [0049] Step 405: determine whether the input device releases the window object, that is, whether the user releases the mouse button or raises his finger to end the dragging operation, if so, perform Step 406, otherwise, perform Step 403.
    [0050] In Step, it is the touch point capture unit that monitors whether the input device releases the window object. After the release information is detected, the touch point capture unit immediately sends the release control information to the drag processing unit, where the release control information includes: the position at the time of release, time , device number, and so on.
    [0051] Step 406: when the drag operation is finished, obtain the initial linear velocity V and the initial angular velocity Va corresponding to the last period Tn of Timer1, and stop Timer1.
    [0052] The drag processing unit obtains, according to the history of the control information, the initial linear velocity V and initial angular velocity Va corresponding to the last period Tn of Timer1 when the input device releases the window object; the obtaining method is described above, and will not be repeated here; the drag processing unit sends the obtained initial linear speed V and initial angular speed Va to the inertia processing unit.
    [0053] Step 407: start a second Timer2 timer, and set the time interval to Tg.
    [0054] In Step, after receiving V and Va, the inertia processing unit starts the second timer Timer2, where Timer2 is used to effect the inertia movement after the input device releases the window object.
    [0055] Step 408: when each Timer2 time interval is greater, obtain the current displacement amount and the rotation amount of the window object according to the Vdec linear speed deceleration and the Vadec angular speed deceleration, record the position at the moment present, and calculate the initial linear velocity V and the initial angular velocity Va next time period.
    [0056] In the step, the inertia processing unit obtains, according to the predefined Vdec and Vadec, the amount of displacement and the amount of rotation used to keep moving forward during the current time interval of Timer2 after the input device releases the window object; the method of obtaining is described above, and will not be repeated here.
    [0057] The method of obtaining the initial linear velocity V and the initial angular velocity Va for the next time period of Timer2 is: Vi = Vj-1-Vdec * Tg; Vai = Vai-1-Vadec * Tg.
    [0058] Step 409: determine if the inertia movement ends, if so, end the process, if not, perform Step 410.
    [0059] The step of determining whether the inertia movement ends includes: determining whether Vi and Vai obtained in Step 408 are less than or equal to 0; if so, stop Timer2, and end the inertia movement process; if a value is less than or equal to 0, and the other value is even greater than 0, then it is still necessary to perform the process of inertia on the other value, for example, when Vi is less than or equal to 0 and Vai is greater than 0, in the current period and in a subsequent period of Timer2, the amount of displacement is 0, and the amount of rotation is not 0; the inertia movement process is not terminated until both Vi and Vai are less than or equal to 0.
    [0060] Step 410: the window object adjusts its position and the rotation angle on the screen according to the amount of displacement and the amount of rotation obtained, in order to achieve the inertia effect; then Step 408 is performed again.
    [0061] The above description is only a preferred embodiment of the present disclosure and should not be used to limit the scope of protection of the present disclosure.
