Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.
In an office or in various releases, discrete application interfaces are gradually used to concentrate contents to be introduced, screen projection devices include mobile phones, televisions and the like, and receiving devices may also be mobile phones, televisions and possibly wall surfaces. The page turning function can be realized by adopting a PPT type mode, but the selection of the content in the page turning function cannot be done, and for a discrete application interface, the page turning function also has a problem that the control is generally carried out according to the horizontal or vertical direction during the operation, and the operation in the oblique line direction is almost not carried out. Therefore, the application provides a control method of the application interface which is completely controlled through Bluetooth and is not limited in control direction.
First, the bracelet is connected to the controlled terminal through a wireless network (preferably bluetooth). The controlled terminal can be a mobile phone, a television, a projector and other devices, and can also be a liquid crystal display screen with an application interface.
The way of manipulation is to calculate the direction and displacement with an acceleration sensor. Because the arm moving distance of the bracelet worn by the user is not too large, the mobile scale factor i is firstly provided in the application. The scale factor is the ratio of the distance that the bracelet moves on the arm to the distance that the corresponding selection point on the controlled end should move. The ratio i is thus stored in the memory unit of the second processor on the application side (controlled side). The second processor further comprises an operation unit, and the operation unit can perform proportional operation on the data from the bracelet received by the application terminal.
On the application interface on the controlled end, a plurality of application icons are arranged, and each application icon has a central position. The most ideal situation is that the application icon is circular or rectangular, the center of the circle is at the center of the circle, and the center of the rectangle is at the intersection point of the diagonals.
An x axis of an application interface and a z axis of the application interface are defined in the application end, and a plane where the x axis and the z axis are located is a plane where the display screen of the application end is located. The bit range for each application is preset. This step is critical and there is no prior art in exactly the same or similar way.
The most preferable application locating range is a circular locating mode, the center position of each application is used as a circle center, and a point with the circle center closest to the application icon is used as a radius to determine a circular surface, and the circular surface is the locating range of the application. There is a case where when two applications are next to each other, there may be some points (coincident points) that fall within the exact range of the first application as well as the exact range of the second application, and therefore, it is necessary to avoid this situation, and we generally adopt a scheme that when there are such points or such edges, we fall right down, that is, when the two applications are in the left-right orientation, such coincident points or such edges fall within the exact range of the right-side application, and when the two applications are in the up-down orientation, such coincident points or such edges fall within the exact range of the lower-side application.
Because the circle is determined, the area between the circles is not in the determination range of any application, and therefore, a determination mode is also a rectangular determination mode, and when the application interface has no application vacancy, the determination mode can cover the whole application interface. When there is an overlapping edge, the above manner of entry of the overlapping point is referred to.
Specifically, the bracelet is set to be an X axis in the direction perpendicular to the arm on the horizontal plane, and to be a Z axis in the direction perpendicular to the arm on the vertical plane. To make the control intuitive, the X-axis and Z-axis are generally chosen. The X and Z axis determinations determine the orientation of the acceleration sensor in the bracelet.
In the bracelet, there is first treater, and first treater includes the judgement module, judges the multiple condition.
It is first determined whether a start gesture exists. Since the bracelet is worn on the wrist all the time, in the screen-throwing state, the wrist may be in the active state all the time, and in order to distinguish the meaningless activities from the activities for controlling the screen-throwing, it is necessary to set the starting gesture. Of course, the start gesture generally need not be so complex that operating the start gesture on each start makes control inefficient. A simple way is to use the Y-axis that is not utilized in the screen-casting, so that the bracelet receives a certain gesture on the Y-axis to start the screen-casting. Of course, there are other ways to use the activation signal, such as turning the wrist, etc.
After judging that the starting gesture occurs, the processor of the bracelet judges that the bracelet firstly has the displacement direction in the X-axis direction and the Z-axis direction within a second time threshold value after the first time threshold value.
The time of the first time threshold is usually very short, typically within 0.5 s. This time is set to ensure that after the user has operated the start gesture, there may be some inertial actions that are meaningless for the manipulation of the application interface and need to be excluded. Thus, here a first time threshold is set to allow the user to adjust the pose of wearing the bracelet and prepare to control the application interface.
The calculated time for each control application interface is set to a second time threshold, which is typically no more than 1 second. Taking the X axis as an example, the first direction having displacement in the X axis direction means that when the user needs to select the point to move to the right, the arm should swing to the positive direction of the X axis first, so that even if the arm may move to the negative direction of the X axis within the second time threshold, the application controls the selection point to the positive direction of the X axis (control to the right); when the user needs to control the selection point to move to the left, the arm should control the bracelet to move to the negative direction of the X axis first. The manner of determination in which the direction having displacement first in the Z-axis direction coincides with the X-axis above.
In addition, most of the cases are that the user's manipulation of the bracelet in the plane defined by the X-axis and Z-axis is almost never only possible with the X-axis forward and backward and the Z-axis forward and backward, most of the time with the displacement in both the X-direction and the Z-direction (taking away the Y-axis influence). For example, when moving, the direction is from the origin to the second quadrant, then the X-axis direction first has a direction in which the displacement is negative, and the Z-axis first has a direction in which the displacement is positive.
The X-axis and the direction having the displacement first in the Z-axis direction are determined, and then the calculation unit in the first processor calculates the sum SX of the displacements in the X-axis direction and the sum SZ of the displacements in the Z-axis direction again in the direction in which the displacement first occurs.
In the second time threshold, possibly on the X axis or the Z axis, the user controls the bracelet to move only in one direction, so that SX and SZ can be obtained by directly calculating the vector from the starting point to the clock point. However, in some cases, when the distance that the user needs to operate is relatively long, one-time arm swinging may not meet the requirement, the user needs to swing back after swinging out once, and then swing out again, or even repeat many times, so SX and SZ need to calculate the sum of the distances on the X axis and the Z axis when swinging out every time, and it needs to be noted that only the user who swings out may not calculate the user who swings back.
After calculating SX and SZ as described above, a distance LX = SX/i that a selection point should be moved in the direction of the first displacement in the X-axis direction of the application side and a distance LZ = SZ/i that should be moved in the direction of the first displacement in the Z-axis direction of the application side are calculated, and a theoretical end position of the selection point is determined (the positive and negative directions of the bracelet in the X-axis or in the Z-axis correspond to the positive and negative directions of the application side in the X-axis or in the Z-axis).
If the theoretical end point position is located within the application interface and within a locating range of a certain application, determining the certain application corresponding to the locating range of the theoretical end point position on the application interface, and locating a selection point to the central position of the application;
if the theoretical end point position is outside the application interface or inside the application interface but not in the locating range of any application, calculating the distance between the central position of each application and the theoretical end point position, locating the selected point to the application closest to the theoretical end point position, and randomly selecting one of the applications and locating the selected point to the randomly selected application when the applications closest to the theoretical end point position are multiple.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
