Detailed Description
The invention provides a method for controlling a large-screen intelligent device, which is suitable for the condition that fingers of adults and children are different in length, and can dynamically change the layout of application icons on a touch screen according to the coordinates or the length of the fingers of a user; when the user points to a far place with hands, the application icons at the far place can be moved to the place which can be reached by the user, and the user can conveniently operate with one hand.
As shown in fig. 1, the method of the present invention works according to the following principle:
firstly, detecting a gesture of a user on a screen through a sensor at a background to acquire coordinates of a start end and a tail end of a finger of the user at present;
secondly, calculating a curve or a linear equation corresponding to the length of the current user finger according to the obtained coordinate data;
third, the icon positions on the screen are re-laid out based on the algorithm of the present invention (described in detail below).
Fourthly, if icons with larger distances need to be operated, the operation of the third step can be repeated in a recursive way.
Finally, the remote application icon can be moved to a place on the screen which can be reached by a user with one hand, and the user can conveniently carry out the operation as required.
Referring to fig. 2 and fig. 3, the icon layout adjustment algorithm provided by the present invention is as follows:
s1, determining a straight line (or curve) equation of the user gesture, further determining a first straight line 21 representing the starting and ending positions of the user finger on the screen 10, and calculating the slope of the first straight line 21 so as to know the direction of the user finger;
s2, determining a second straight line 22 on the screen 10, which passes through the beginning 11 of the user' S finger and is parallel to the width direction of the screen;
s3, determining a third straight line 23 on the screen 10, which passes through the end 12 of the user' S finger and is parallel to the width direction of the screen;
s4, determining a first area 31 on the screen 10 between below the first straight line 21 and above the second straight line 22;
s5, determining a second area 32 located on the screen 10 and located on the right side of the first straight line 21 and between the second straight line 22 and the third straight line 23;
s6, the icons of the first area 31 are dynamically released to the second area 32, and the icons of the second area 32 are dynamically released to the first area 31, that is, the icons of the first area 31 and the second area 32 are randomly exchanged. The first area 31 and the second area 32 are dynamically sized to match the length of each person's finger and the point at which the person touches the screen.
Alternatively, S5 may have other embodiments, which are denoted as S5', for example, a third area 33 located on the left side of the first straight line 21 and between the second straight line 22 and the third straight line 23 is determined on the screen 10; then, in the subsequent step S6', the icons of the first area 31 and the third area 33 may be exchanged.
Although not described in detail above, it can be understood from the drawings that the screen regions can be actually divided by matching the upper, lower, left and right boundaries of the screen with the first straight line 21, the second straight line 22, and the third straight line 23 (the first region 31 can be also expressed as a region surrounded by the right boundary of the screen, the first straight line 21, and the second straight line 22). In principle, two of all screen areas on the screen 10, which are collectively divided by the boundaries and straight lines, may be optionally used as icon exchange areas, and only a few preferred examples thereof are described above.
If it is assumed that the region division and adjustment method described in the above embodiments corresponds to the implementation of the left-handed (or right-handed) operation of the screen; it will be understood by those skilled in the art that when the screen is operated by the right hand (or left hand), the start and end points of the fingers on the screen, the direction of the first straight line, the division of the area, etc. may be changed accordingly, for example, in a position symmetrical to the left and right in fig. 3 and 4. However, the principle and process of dividing the icon exchange area by the algorithm in the right-hand operation and the left-hand operation are similar, and are not described in detail here.
The two dots in FIG. 3 represent the beginning 11 and end 12 of the finger abstractly; in this case, the slope calculation may be performed by using the line from the end 12 to the start 11 of the user's finger on the screen 10 to the extension thereof as the first straight line 21.
In addition, when a certain user operates the mobile phone irregularly, namely operates the screen under the condition that the fingers are bent, the intelligent device can roughly draw the curve through calculation, determine the highest point of the curve, and obtain the tangent line of the highest point of the gesture operation through calculus.
As shown in fig. 5, if the gesture curve is a convex line curve, the highest point is the most convex point Q (X, Y) of the curve, the tangent line F of the curve passing through the highest point corresponds to the first straight line, the straight line S passing through the highest point and parallel to the bottom edge of the screen corresponds to the second straight line, and the straight line T passing through the end (a point) of the finger and parallel to the bottom edge of the screen corresponds to the third straight line, then the corresponding icon exchange area can be determined according to the algorithm described above. Or, in another example of the convex curve, a straight line P passing through the start end (point B) of the finger and parallel to the bottom side of the screen is taken as a second straight line, and other operations are not changed.
As shown in fig. 6, if the gesture curve is a concave curve, the highest point is determined to be the beginning of the finger (point B), a curve tangent line s passing through the highest point (in this example, a straight line passing through the highest point and perpendicular to the bottom edge of the screen) is taken as a first straight line, a straight line s passing through the highest point and parallel to the bottom edge of the screen is taken as a second straight line, and a straight line t passing through the end of the finger (point a) and parallel to the bottom edge of the screen is taken as a third straight line, and then the corresponding icon exchange area can be determined according to the algorithm described above.
Referring to fig. 4, when the user touches the screen with a finger, the sensor (based on pressure or thermal sensing technology) on the smart device can directly acquire coordinates a (X1, Y1) and B (X2, Y2) of the two points on the screen corresponding to the end and the beginning of the finger. Then, icon exchange areas (a first area D and a second area D) are determined according to the above algorithm, and icons in the two areas are exchanged, respectively. In the above example, the icons in the two areas are randomly exchanged, and no specific constraint exists; in other embodiments, some corresponding conditions may be added to the icon exchange according to the actual situation.
As the slope k = | Y2-Y1|/| X2-X1|, of the straight line between the two points at the beginning and the end of the finger increases, the range of the region D, d becomes larger and larger with the increasing k, and the number of icons exchanged with each other also becomes larger. For example, the ICON ICON1 could be arbitrarily swapped with ICONs in ICON5-ICON12 at the beginning, and as k increases, the ICONs ICON2-ICON4 would then also be swapped with ICONs in the underlying area.
In order to operate icons which are further away, the user can adjust the gesture operation of the user, and the intelligent device recalculates a new icon exchange area based on the algorithm of the invention. For example, in the example shown in fig. 4, the slope may be increased to enlarge the icon exchange area by moving one finger of the user on the screen in such a manner that the end position is substantially stationary and the start position is moved to the left of the screen as shown in the figure; conversely, if the start point moves to the right of the figure, the slope can be decreased to decrease the icon switched area.
In some embodiments, the beginning of the finger is the tip of one finger (e.g., thumb or index finger) of the user, and the end of the finger corresponds to the distal segment or root of the one finger of the user (i.e., a position near the palm). For example, in the first step, the user touches a finger for operating the screen on the screen so that the sensor acquires coordinates of two points as the start and end points.
Alternatively, in other embodiments, the beginning of the finger is the tip of one of the user's fingers (e.g., the thumb) and the end of the finger is the tip of the other of the user's fingers (e.g., the index finger). For example, in the first step, the user performs a zoom-in gesture or a zoom-out gesture on the screen with two fingers, and the sensor acquires the touch positions of the fingertips of the two fingers as the starting ends.
If the same user adjusts the gesture of touching the screen, for example, if one finger is not fully extended to be fully extended, or if the gesture of enlarging the distance between two fingertips of the user is performed, which is equivalent to increasing the distance between the beginning and the end of the screen, the smart device will adjust the corresponding icon exchange area according to the above algorithm and rearrange the icon positions.
In different examples, each re-layout of the icons can be performed on the basis of the previous layout adjustment in a superimposed manner; it may be preset that the icon layout is temporarily adjusted every time the user performs an icon operation (or is set to be not operated within a time limit), and then the icon layout is returned to the icon layout before the adjustment.
In summary, the control method provided by the present invention monitors the gesture operation of the user on the screen in real time, and obtains the coordinates of the beginning and end points of the finger, so as to determine the corresponding icon exchange area and adjust the icon layout. The large-screen intelligent device is a device which can not be operated by a single hand of a user to all icons on a screen, and the method is particularly suitable for the device. The present invention is not limited to the solution of applying the method described in the above embodiments to other devices to improve the user experience.
While the present invention has been described in detail with reference to the preferred embodiments, it should be understood that the above description should not be taken as limiting the invention. Various modifications and alterations to this invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be determined from the following claims.
