BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a block diagram of an electronic device according to an embodiment of the application;
FIG. 2 shows an example of a simulated diagram of the electronic device of FIG. 1; and
FIG. 3 shows an example of the incoming call answering and rejecting method according to an embodiment of the application.



DETAILED DESCRIPTION OF THE APPLICATION
Referring to FIG. 1, a block diagram of an electronic device according to an embodiment of the application is shown. The electronic device 100, such as a touch phone, a smartphone, or a personal digital assistant (PDA) phone, comprises a call module 110, a touch screen 120, and a processing unit 130. The call module 110 receives a request of an incoming call “Ca.” The touch screen 120 generates a dragging signal “Sd.” The processing unit 130 is coupled to the call module 110 and the touch screen 120. When the processing unit 130 determines that the dragging signal Sd is an answering signal Sa, the incoming call Ca is answered. When the processing unit 130 determines that dragging signal Sd is a rejecting signal Sr, the incoming call Ca is rejected (ignored). Thus, the user answers or rejects (ignores) the incoming call Ca by generating a dragging signal on the touch screen 120, hence avoiding the touch screen 120 being touched accidentally to cause the incoming call be answered or rejected unexpectedly.
Referring to FIG. 2, an example of a simulated diagram of the electronic device of FIG. 1 is shown. When the call module 110 receives a request of an incoming call Ca, a caller pattern 111 is shown on the touch screen 120 to inform the user of the caller's information comprising at least one of the telephone number, the name, and the photo of the caller. The touch screen 120 has a first area 121, a second area 122, and an initial area 123. The first area 121 and the second area 122 are located at two opposite sides of the initial area 123. The answering signal Sa is a signal generated by dragging from the initial area 123 towards the first area 121, and the rejecting signal Sr is a signal generated by dragging from the initial area 123 towards the second area 122. Thus, the user can generate an answering signal Sa to answer the incoming call Ca by pressing his or her finger on the initial area 123 and dragging towards the first area 121. Or, the user can generate a rejecting signal Sr to reject the incoming call Ca by pressing his or her finger on the initial area 123 and dragging towards the second area 122.
In one embodiment of the application, a first reminder 124 is shown in the first area 121 of the touch screen 120 and a second reminder 125 is shown in the second area 122. Thus, the user is informed whether to answer the incoming call Ca by dragging from the initial area 123 towards the first area 121 or to reject the incoming call Ca by dragging from the initial area 123 towards the second area 122. In the present embodiment of the application, the first reminder 124 is an answering message such as “slide to answer”, and the second reminder 125 is a rejecting message such as “slide to reject” or “slide to ignore.”
In one embodiment of the application, a button 126 is shown in the initial area 123 of the touch screen 120. When the user generates the answering signal Sa by dragging from the initial area 123 towards the first area 121, the processing unit 130 controls the button 126 to move to the first area 121 from the initial area 123. When the user generates the rejecting signal Sr by dragging from the initial area 123 towards the second area 122, the processing unit 130 controls the button 126 to move the second area 122 from the initial area 123. Thus, the user is informed whether to answer or reject the incoming call Ca. In another embodiment, the processing unit 130 controls the button 126 to dynamically move to the first area 121 or the second area 122 from the initial area 123 so as to provide the user with virtual feeling of dragging the button. That is to say, the user may generate the answering signal Sa by dragging the button 126 towards the first area 121 from the initial area 123; and the user may generate the rejecting signal Sr by dragging the button 126 towards the second area 122 from the initial area 123. The user may release the button 126 after dragging the button 126 to the first area 121 or the second area 122. After the user releases the button 126, the processing unit 130 controls the button 126 to dynamically move back to the initial area 123 from the first area 121 or the second area 122 so as to provide the user with superior visual effect.
In the present embodiment of the application, the answering signal Sa or the rejecting signal Sr is generated by dragging from the initial area 123 towards the first area 121 or the second area 122. However, the above exemplification is not for limiting the application. In another embodiment of the application, the answering signal Sa may be generated by dragging from the first area 121 towards the initial area 123, and the rejecting signal Sr may be generated by dragging from the second area 122 towards the initial area 123.
In other embodiments of the application, the answering signal Sa may be generated by drawing a first symbol previously defined on the touch screen 120, and the rejecting signal Sr is a signal generated by drawing a second symbol previously defined on the touch screen 120. In one embodiment, the answering signal Sa only generated when the first symbol is substantially drawn in the first area 121, and the rejecting signal Sr only generated when the second symbol is substantially drawn in the second area 122. The first symbol or the second symbol, for example, is a pattern comprising a tick pattern, an X pattern, an a pattern, a clockwise circle pattern, or an anti-clockwise circle pattern, a symbol, or a character.
Referring to FIG. 3, an example of the incoming call answering and rejecting method according to an embodiment of the application is shown. In the incoming call answering and rejecting method of the present embodiment of the application, the steps of FIG. 3 are executed by an electronic device 100 of FIG. 2, but the application is not limited thereto. Anyone who is skilled in the technology of the application will understand that the procedures and sequences of the incoming call answering and rejecting method can be modified or adjusted according to actual needs.
Firstly, the method begins at step S310, a request of an incoming call Ca is received by a call module 110. Next, the method proceeds to step S320, a first reminder 124 is shown in the first area 121 to inform the user to answer the incoming call Ca by dragging from the initial area 123 towards the first area 121. The first reminder 124 is an “Answer” message for example. Then, the method proceeds to step S330, a second reminder 125 is shown in the second area 122 to inform the user to reject the call Ca by dragging from the initial area 123 towards the second area 123. The second reminder 125 is a “Reject” or “Ignore” message for example.
Then, the method proceeds to step S340, the touch screen 120 receives the dragging signal Sd generated by dragging from the initial area 123 towards the first area 121 to generate an answering signal Sa. After that, the method proceeds to step S350, when the touch screen 120 receives the dragging signal Sd generated by dragging from the initial area 123 towards the first area 121, the processing unit 130 moves the button 126 to the first area 121 from the initial area 123. Preferably, the button 126 is dynamically moved to the first area 121 from the initial area 123.
Afterwards, the method proceeds to step S360, the touch screen 120 receives the dragging signal Sd generated by dragging from the initial area 123 towards the second area 122 to generate a rejecting signal Sr. Then, the method proceeds to step S370, when the touch screen 120 receives the dragging signal Sd generated by dragging from the initial area 123 towards the second area 122, the processing unit 130 moves the button 126 to the second area 122 from the initial area 123. Preferably, the button 126 is dynamically moved to the second area 121 from the initial area 123.
Then, the method proceeds to step S380, when the generated dragging signal Sd is the answering signal Sa, the incoming call Ca is answered. Lastly, the method proceeds to step S390, when the generated dragging signal Sd is the rejecting signal Sr, the incoming call Ca is rejected.
In another embodiment, in step S320, the first reminder 124 shown in the first area 121 may be a pattern, a symbol, or characters informing the user that he or she can answer the incoming call Ca by dragging from the first area 121 towards the initial area 123. Likewise, in step S330, the second reminder 125 shown in the second area 122 may be a pattern, a symbol, or characters informing the user that he or she can reject the incoming call Ca by dragging from the second area 123 towards the initial area 123.
In another embodiment, the answering signal Sa can be a signal generated by drawing a first symbol previously defined on the touch screen 120, and the rejecting signal Sr can also be a signal generated by drawing a second symbol previously defined on the touch screen 120. In one embodiment, the answering signal Sa only generated when the first symbol is substantially drawn in the first area 121, and the rejecting signal Sr only generated when the second symbol is substantially drawn in the second area 122. The first symbol or the second symbol, for example, is a pattern comprising a tick pattern, an X pattern, an a pattern, a clockwise circle pattern, or an anti-clockwise circle pattern, a symbol, or a character.
The above incoming call answering and rejecting method may be programmed and stored in a digital data storage medium executable on the handheld electronic device 100. The digital data storage medium, such as secure digital (SD) card, memory stick (MS), and multimedia memory card (MMC), has the above application executing function after the application executing method is executed on the handheld electronic device 100.
According to the electronic device, the incoming call answering and rejecting method, and the digital data storage media disclosed in the above embodiments of the application, the incoming call is answered or rejected according to the dragging signal received by the touch screen. When the generated dragging signal is a previously defined answering signal, the incoming call is answered. When the generated dragging signal is a previously defined rejecting signal, the incoming call is rejected. The answering signal and the rejecting signal can be generated according to “dragging from the initial area towards a particular area on the touch screen” or “drawing a particular pattern or symbol on the touch screen”. Thus, the user will no more answer or reject the incoming call unintentionally caused by accidental touch and gain superior use experience.
While the application has been described by way of example and in terms of a number of embodiments, it is to be understood that the application is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
