Reporters obtained the following quote from the background information supplied by the inventors: "The invention relates to a method for displaying images of a touch control device on an external display device, and more particularly, to a method for controlling a graphical icon in the displayed images according to control input received from the touch control device.
"As related technology keeps improving, conventional feature phones are gradually replaced by touch-controlled smart phones embedded with various kinds of application programs. A screen of a touch-controlled smart phone is generally small, such that when a user of the smart phone tries to demonstrate an image displayed on the smart phone to other people, the user may couple the smart phone to an external display device via a wireless network or a signal cable to transmit the image of the smart phone to the external display device. The operation system of a smart phone normally supports touch control operations, such as scrolling, tapping, zoom-in, zoom-out and/or other gestures. In the condition that user wishes to perform operation on certain part of the displayed content, for example directing to another link on a website, user might need to scroll the webpage to proper position, zoom in the displayed image so that it would be easier to tap on the link. However, it often occurs that another nearby link may be selected instead of the intended link due to the touch screen wrongly identifies the position of the tap input. As a result, it causes inconvenience of controlling operation of the smart phone."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "One embodiment of the invention discloses a method for displaying images of a touch control device on an external display device. The method comprises providing a graphical icon on the image displayed on the external display device; providing a control interface for controlling the graphical icon on the touch control device; receiving a control signal from the control interface; and performing an operation corresponding to the control signal.
"Another embodiment of the invention discloses a touch control device comprising: a touch input interface unit, configured to receive a touch input; a processing unit, configured to process a control signal corresponding to the touch input; and an image processing unit, configured to provide an image displayed with a graphical icon; wherein the graphical icon is controlled according to the control signal.
"Yet another embodiment of the invention discloses a method for displaying images of a touch control device on an external display device, comprising: detecting a connection of the touch control device to the external device; and switching from a first display mode to a second display mode for displaying an image on the external device in response to the connection being detected; wherein the second display mode provides additional graphics user interface not supported in the first display mode.
"These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
