Title: Display method for touchscreen and terminal

Description:
FIELD OF THE TECHNICAL 
     The present invention relates to communication technology field, and particularly to a display method for a touchscreen and a terminal. 
     BACKGROUND 
     At present, on an incoming interface of a terminal, when a user wants to answer or reject a call, the user needs to click the answer or reject button, or answers or rejects the call via sliding. Some optimized answering methods need a user to click a clickable region set by the interface and slide up or down to answer/reject a call. 
     The shortcoming of such operation methods is that when a user wants to answer or reject a call, the user needs to click a corresponding region of the interface. When the screen is great, it is difficult for the user to touch the clickable region and slide, so it is not convenient for the user to perform operations by one hand. Currently, there is no related art to solve the problem. 
     SUMMARY 
     The present invention aims to solve one of technical problems in prior art. 
     Therefore, a purpose of the present invention is to provide a display method for a touchscreen, so as to facilitate a user to perform operations by one hand 
     Another purpose of the present invention is to provide a terminal. 
     To realize the above purposes, embodiments in accordance with a first aspect of the present invention provide a display method for a touchscreen which includes acquiring the position of a touch point on the touchscreen when an incoming call interface is displayed, and displaying a plurality of touch buttons around the touch point. 
     According to the display method for the touchscreen in the embodiments of the present invention, display modes of the touch buttons can be correspondingly changed along with the change of the position of the touch point. The touch point is the position of the touchscreen touched by an input object, such as a user&#39;s finger. By doing so, the display positions of the touch buttons can be changed dynamically, so as to facilitate a user to perform operations by one hand. 
     Furthermore, the display method for the touchscreen in the above embodiments of the present invention can further include the following additional technical features. 
     According to an embodiment of the present invention, the step of displaying the touch buttons around the touch point specifically includes displaying the touch buttons at any positions of an overlapping region between a circle region the center of which is the touch point and the touch screen. The touch buttons can be displayed in adaptive mode along with the change of the touch point. 
     According to an embodiment of the present invention, the touch buttons are displayed above and below the touch point symmetrically or displayed on the left and right of the touch point symmetrically. 
     According to an embodiment of the present invention, when the position of the touch point falls within an edge region of the touchscreen, the touch buttons are displayed on an arc the center of which is the touch point and are all further displayed on one side of the touch point. When the position of the touch point falls within the edge region of the touchscreen, the touch buttons should be displayed on one side of the touch point, and cannot be displayed around the touch point randomly. By doing so, it facilitates a user to use his/her finger to touch the touch buttons in a great space, thereby reducing error triggering. 
     According to an embodiment of the present invention, the display method for the touchscreen can further include displaying the dragging button on the touch point, and displaying the touch buttons around the dragging button at intervals; executing a function corresponding to any of the touch buttons when the dragging button is dragged to the position of any of the touch buttons. 
     To facilitate the user to sense the touch point, the dragging button is displayed above the touch point. The dragging button can be dragged by the user. The touch buttons displayed on the current interface are displayed around the dragging button at intervals, so as to facilitate the user to drag the dragging button to any touch button without triggering other touch buttons incorrectly. 
     According to an embodiment of the present invention, a line connecting the display positions of the touch buttons together is arc-shaped. When the user performs operations by one hand, the thumb is typically used to perform touch operations. As when the thumb slides up and down, the sliding track is typically arc-shaped, thus to facilitate the user to use the thumb to perform touch operations, the touch buttons are arranged in arc, which can cause the positions of the touch buttons to be on the possible sliding track of the thumb, thereby facilitating the thumb to touch the corresponding touch button conveniently as far as possible. 
     According to an embodiment of the present invention, the dragging button is arranged on an arc-shaped connection line. When the touch buttons are arranged in arc, the dragging button is arranged to be adjacent to the touch buttons as far as possible, which facilitates the user to drag the dragging button to a specified touch button when the user performs operations by one hand. 
     According to an embodiment of the present invention, the dragging button is arranged between any two of the touch buttons. When the touch buttons are arranged on the sliding track of the thumb, to reduce error triggering, the touch buttons are arranged on two sides of the dragging button. 
     According to an embodiment of the present invention, when the position of the dragging button is at the edge of the touchscreen, the touch buttons are displayed on an arc the center of which is the dragging button. 
     When the position of the dragging button is not at the edge of the touchscreen, the dragging button and the touch buttons can be arranged in arc. However, when the position of the dragging button is at the edge of the touchscreen, as the display region on one side of the dragging button is limited, the touch buttons cannot be displayed in the display region. Therefore, under this condition, the dragging button and the touch buttons cannot be arranged in arc, and the display positions of the touch buttons can be dynamically changed according to the specific position of the dragging button. 
     According to an embodiment of the present invention, the display method for the touchscreen can further include detecting the size of the area of the touchscreen taken up by the touch point; adjusting the display size of each touch button in adaptive mode according to the size of the detected touch point. 
     Fingers of different users may have different sizes and shapes. Therefore, to facilitate a user to better touch the touch buttons, the sizes of the touch buttons can be adjusted according to the size of the area of the touchscreen taken up by the user&#39;s finger, thereby further enhancing the flexibility of the display of the touch buttons. 
     According to an embodiment of the present invention, the touch buttons include at least one of or a combination of the following: an answer button, a reject button, and a notification prompt button. 
     To realize the above purposes, embodiments in accordance with a second aspect of the present invention provides a terminal which includes an acquisition unit configured to acquire the position of a touch point on the touchscreen when the incoming call interface is displayed, and a displaying unit connected to the acquisition unit and configured to display a number of touch buttons around the touch point.

     As shown in  FIG. 1A , an exemplary embodiment of the present invention provides a terminal  100  which includes an acquisition unit  102  configured to acquire the position of a touch point on the touchscreen, and a displaying unit  104  connected to the acquisition unit  102  and configured to display a number of touch buttons in adaptive mode according to the position of the touch point. 
     The terminal in the embodiment of the present invention can correspondingly change display modes of the touch buttons along with the change of the position of the touch point. The touch point is the position of the touchscreen touched by an input object, such as a user&#39;s finger. By doing so, the display positions of the touch buttons can be changed dynamically, so as to facilitate a user to perform operations by one hand. 
     According to an embodiment of the present invention, the displaying unit  104  is further configured to display the touch buttons at any positions of an overlapping region between a circle region the center of which is the touch point and the touchscreen. The touch buttons can be displayed in adaptive mode along with the change of the touch point. 
     According to an embodiment of the present invention, the touch buttons are displayed above and below the touch point symmetrically or displayed on the left and right of the touch point symmetrically. As shown in  FIG. 1B , touch buttons  200  (an answer touch button and a reject touch button) are displayed on an incoming call interface, and a dragging button is displayed on the touch point  204 . To facilitate the user to answer a call by one hand, the answer touch button and the reject touch button can be displayed above and below the dragging button symmetrically. Beside this, as shown in  FIG. 1C , the answer touch button and the reject touch button are displayed on the left and right of the dragging button symmetrically. 
     According to an embodiment of the present invention, when the position of the touch point falls within an edge region of the touchscreen, the displaying unit  104  is further configured to display the touch buttons on an arc the center of which is the touch point and further display all the touch buttons on one side of the touch point. When the position of the touch point falls within the edge region of the touchscreen, the touch buttons should be displayed on one side of the touch point, and cannot be displayed around the touch point randomly. By doing so, it facilitates the user to use his/her finger to touch the touch buttons in a great space, thereby reducing error triggering. 
     According to an embodiment of the present invention, the displaying unit  104  is further configured to display the dragging button on the touch point, and display the touch buttons around the dragging button at intervals. The terminal can further include a control unit  106  connected to the displaying unit  104 , and when the dragging button is dragged to the position of any of the touch buttons, the control unit  106  executes a function corresponding to the any of the touch buttons. To facilitate the user to sense the touch point, the dragging button is displayed above the touch point. The dragging button can be dragged by the user. The touch buttons displayed on the current interface are displayed around the dragging button at intervals, so as to facilitate the user to drag the dragging button to any touch button without triggering other touch buttons incorrectly. 
     According to an embodiment of the present invention, a line connecting the display positions of the touch buttons together is arc-shaped. When the user performs operations by one hand, the thumb is typically used to perform touch operations. As when the thumb slides up and down, the sliding track is typically arc-shaped, thus to facilitate the user to use the thumb to perform touch operations, the touch buttons are arranged in arc, which can cause the positions of the touch buttons to be on the possible sliding track of the thumb, thereby facilitating the thumb to touch the corresponding touch button conveniently as far as possible. 
     According to an embodiment of the present invention, the dragging button is arranged on an arc-shaped connection line. When the touch buttons are arranged in arc, the dragging button is arranged to be adjacent to the touch buttons as far as possible, which facilitates the user to drag the dragging button to a specified touch button when the user performs operations by one hand. 
     According to an embodiment of the present invention, the dragging button is arranged between any two of the touch buttons. When the touch buttons are arranged on the sliding track of the thumb, to reduce error triggering, the touch buttons are arranged on two sides of the dragging button. 
     According to an embodiment of the present invention, the displaying unit  104  is further configured to display the touch buttons on an arc the center of which is the dragging button when the position of the dragging button is at the edge of the touchscreen. 
     According to an embodiment of the present invention, the terminal further includes a detecting unit  108  configured to detect the size of the area of the touchscreen taken up by the touch point. The displaying unit  104  is further configured to adjust the display size of each touch button according to the size of the touch point. Fingers of different users may have different sizes and shapes. Therefore, to facilitate a user to better touch the touch buttons, the size of the touch buttons can be adjusted according to the size of the area of the touchscreen taken up by the user&#39;s finger, thereby further enhancing the flexibility of the display of the touch buttons. 
     According to an embodiment of the present invention, the touch buttons include at least one of or a combination of the following: an answer button, a reject button, and a notification prompt button. 
     The following will specifically illustrate the display principle of the touch buttons of the embodiments of the present invention in conjunction with  FIGS. 2-4 , taking an incoming call scenario for an example. 
     As shown in  FIG. 2 , the incoming call interface mainly includes three touch buttons: touch buttons  202  and a dragging button  204 . In this embodiment, the touch buttons  202  include an answer button and a reject button. When there is a new incoming call and the user uses a finger to touch the incoming call interface, the dragging button  204  is displayed on the touch point, and the display of the dragging button  204  changes along with the change of the position of the touch point. That is, the position of the touch point is the position of the dragging button. The arrangement of the answer button and the reject button also changes along with the change of the position of the dragging button  204 , and  FIGS. 3-4  illustrate the detailed change mode. 
     It should be noted that in  FIG. 2 , if the position of the touchscreen touched by the finger is not within the edge region of the touchscreen, the position of the dragging button  204  is the position of the touchscreen touched by the finger. When the touchscreen is great, if the user performs operations by one hand, the user usually uses his/her thumb to perform operations. When the user users the thumb to perform operations, the sliding track of the thumb on the touchscreen is generally arc-shaped. Therefore, to facilitate the thumb to touch the corresponding touch button conveniently, the touch buttons and the dragging button are arranged in arc. By doing so, the dragging button  204  can be smoothly dragged to the corresponding touch button no matter whether the dragging button  204  is dragged up or down by the thumb. 
     As shown in  FIG. 3 , if the position touched by the user&#39;s finger is within the edge region of the touchscreen (four side edges of the touchscreen), the touch buttons  202  and the dragging button  204  cannot be arranged in arc. At this point, the touch buttons  202  are displayed adjacent to another side of the dragging button  204 , which can also facilitate control of the touch buttons  202  during one hand operation. 
     As shown in  FIG. 4 , if the position touched by the user&#39;s finger is within any of four corners of the touchscreen, the touch buttons  202  and the dragging button  204  cannot be arranged in arc. At this point, the touch buttons  202  are displayed adjacent to another side of the dragging button  204 , which can also facilitate control of the touch buttons  202  during one hand operation. 
     Therefore, the touch buttons of the present invention can be displayed in adaptive mode according to the position of the touch point. When the left hand is used to perform operations, if the position of the touch point is at bottom left (edge region), the touch buttons can be mainly displayed on the right side of the touch point (upper right or bottom right). When the right hand is used to perform operations, if the position of the touch point is at bottom right (edge region), the touch buttons can be mainly displayed on the left side of the touch point (upper left or bottom left). Furthermore, the touch buttons are arranged on an arc the center of which is the touch point, which enables the user to operate the touch buttons whenever and whereever when the user performs operations by one hand, thereby user&#39;s operation is not limited by the positions of the touch buttons. 
       FIGS. 2-4  just show display modes of the touch buttons when several representative positions of the touchscreen are touched by a finger. Beside these, those skilled in the art should understand that when a finger touches any other position of the touchscreen, the touch buttons can be displayed in adaptive mode according to the position of the dragging button, which will not be repeated herein. 
     As fingers of different persons may have different sizes and shapes, the sizes of the positions of the touchscreen touched by different fingers may be different. For example, as the fingers of children are small, the size of the touch point is relative small, while the fingers of adult are great, the size of the touch point is relative great. To adapt to this change, the terminal can detect the touch size, and adjust the display sizes of the touch buttons  202  according to the touch size. As shown in  FIG. 5 , comparing to the touch buttons  202  shown in  FIG. 2 , the display sizes of the touch buttons  202  become greater. Similarly, if the size of the touch point is small, the display sizes of the touch buttons  202  will become small. 
     The following will specifically illustrate the embodiments of the present invention in conjunction with  FIG. 6  and  FIG. 7 , taking a lock interface for an example. 
     As shown in  FIG. 6 , the lock interface includes the touch buttons  202 . In this embodiment, the touch buttons includes an unlock button and a short message notification button. On the lock interface, if the user uses his/her finger to touch the touchscreen, the dragging button  204  is displayed on the touch point touched by the finger. The display of the dragging button  204  can change along with the change of the touch point. If a new short message is received when the terminal is in the lock state, the short message notification button will be displayed on the lock interface, and the number of new short messages is also displayed. When the user uses his/her finger to touch the touchscreen, the touch buttons  202  are arranged in adaptive mode according to the position of the dragging button  204 . In  FIG. 6 , the position of the dragging button  204  is not within the edge region of the touchscreen, thus there is enough space for display of the touch buttons  202 . Similarly, to facilitate the user to perform operations by one hand and to conform to the sliding track of the thumb, after the touch buttons  202  are adjusted in adaptive mode, the touch buttons  202  and the dragging button  204  cooperatively form an arc. 
     As shown in  FIG. 7 , on the lock interface, in this embodiment, the touch buttons  202  include an unlock button and a missing call notification button. In other words, besides the short message notification button, there are touch buttons such as the missing call notification button. Similarly, the touch buttons are adjusted in adaptive mode according to the position of the dragging button. In  FIG. 7 , as the position of the dragging button is within the below edge region of the touchscreen, the touch buttons  202  can only be displayed above the dragging button  204 . 
     As shown in  FIG. 8 , when the user uses his/her finger to touch the touchscreen, the dragging button is moved from the other position to the position of the touch point, and the display of the touch buttons dynamically changes along with the change of the position of the touch point. 
     Therefore, under the condition of that there is a new incoming call, when an input object such as a finger touches any position of the touchscreen, the user can answer or reject the call by performing operations on the any position, so as to facilitate user&#39;s operations. Especially when the touchscreen is a great screen, it is facilitate the user to perform operations by one hand. Under other scenario, for example, for the lock interface and any application interface, such display scheme can be employed. 
       FIG. 9  is a schematic flow chart of a display method for a touchscreen in accordance with an exemplary embodiment of the present invention. 
     As shown in  FIG. 9 , to realize the above purposes, an embodiment in accordance with a second aspect of the present invention provides a display method for a touchscreen which can include step  902 , acquiring the position of a touch point on the touchscreen, and step  904 , displaying a number of touch buttons in adaptive mode according to the position of the touch point. 
     According to an embodiment of the present invention, the step of displaying the touch buttons around the touch point specifically includes displaying the touch buttons at any positions of an overlapping region between a circle region the center of which is the touch point and the touch screen.
