DETAILED DESCRIPTION OF THE INVENTION
The following description shows some embodiments carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
FIG. 1A illustrates a phone 100 with a touch panel 102, wherein the touch panel 102 shows an embodiment of a first user interface. The first user interface comprises numeric icons 104 and a dialing icon 106 for the user to dial a phone number.
FIG. 1B illustrates an embodiment of a second user interface. The second user interface comprises icons for controlling the phone 100. For example, users can tap the icons of the second user interface to adjust the speaker volume (by tapping icon 108) or to hold the call (by tapping icon 110).
FIG. 2 illustrates an embodiment of the invention, which comprises a touch panel 202 and a controller 204. For dialing a phone number, the touch panel 202 may be controlled to display a first user interface, such as that shown by FIG. 1A, comprising numeric icons 104 and a dialing icon 106. After the dialing icon 106 is tapped by the user, the controller 204 maintains display of the first user interface until an interrupt signal 206 enters the controller 204. Unlike the conventional phone, wherein the user interface is switched once the dialing icon 106 is tapped, the invention controls the touch panel 202 to switch from the first user interface to a second user interface (such as that shown by FIG. 1B) according to the interrupt signal 206 which occurs later than tapping of the dialing icon 106.
The conventional phones, which may switch from the first user interface to the second user interface once the dialing icon 106 is tapped, are inconvenient to voice service systems in which the user may need the first user interface shown in FIG. 1A to dial an extension or follow the instructions from the voice service system. In these cases, the users of the conventional phones have to tap the keyboard icon 112 of the second user interface to switch the touch panel 102 to the first user interface to show the numeric icons 104.
Compared with the users of the conventional phones, the user of the invention can directly dial an extension or follow the instructions of the voice service system without switching the user interface.
FIG. 3 illustrates another embodiment of the invention. Compared with the embodiment shown in FIG. 2, FIG. 3 further comprises a voice receiver 302. The voice receiver 302 is operable to receive conversation 304 from the user. In some embodiments, the interrupt signal 206 is generated when the voice receiver 302 detects that the conversation comprises a predetermined phrase, such as ‘hello’ or ‘may I speak with’ or any other phrases. Because users usually don't say the predetermined phrases while dialing an extension or using a voice service, the embodiments can maintain display of the first user interface comprising numeric icons (such as those shown by 104) under a voice service system. Thus, the user doesn't have to switch user interfaces for dialing an extension or following the instructions from the voice service system.
In another embodiment, the voice receiver 302 may generate the interrupt signal 206 after the conversation 304 has been received for a period of time. In another embodiment, the voice receiver 302 may generate the interrupt signal 206 immediately when the voice receiver 302 receives a conversation 304.
In some embodiments, the interrupt signal 206 is generated when a switch button on the case of the phone is pressed. In these cases, the switching of the user interface is controlled by the user. The switch button may be a specially designed button on the case of the phone, or may be any of the conventional buttons on the case of the phone.
The invention may disable a touch function of the touch panel 202 when the voice receiver 302 receives conversation 304. Thus, the invention can avoid the touch panel 202 from being accidentally touched during a conversation.
The invention further discloses methods for controlling a touch panel of a phone. FIG. 4 is a flowchart of the invention. In the flowchart, the touch panel is initially controlled to display a first user interface comprising numeric icons and a dialing icon for the user to dial a phone number. Step S402 detects whether the dialing icon is tapped by the user. If the dialing icon is tapped, the method enters step S404 to detect an interrupt signal. When the interrupt signal is detected, the method enters step S406 to switch the touch panel from the first user interface to a second user interface. The second user interface may comprise icons controlling the functions of the phone, such as adjusting the speaker volume or holding the call.
The interrupt signal may be generated by several ways. In some embodiments, the interrupt signal is generated when a voice receiver of the phone receives a predetermined phrase such as ‘hello’ or ‘may I speak with’ or any other phrases. In some embodiments, the interrupt signal is generated once a conversation from the user is detected. In some embodiments, the interrupt signal is generated after a conversation has been detected for a period of time. In some embodiments, the interrupt signal is generated when a switch button on the case is touched, wherein the switch button may be a specially designed button or one of the conventional buttons on the case of the phone.
The method of the invention may further disable a touch function of the touch panel when the voice receiver receives a conversation.
The phones of the invention may be indoor phones or mobile phones or any phones with touch panels.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded to the broadest interpretation so as to encompass all such modifications and similar arrangements.
