Input Interface Preview Display for Electronic Device Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for switching input interfaces on electronic devices, such as televisions, are inefficient and difficult for users to navigate, requiring significant time and not providing intuitive identification of the intended input device.
Innovation Solution
Acquiring information from input devices through their interfaces and displaying this information to the user, allowing them to select the desired interface based on visual or textual representations of the data being played, thereby improving switching speed and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the television processes audio and video switching when the user presses the SWITCH button, then the input device can be switched, but the user needs to wait for a certain period of time and cannot judge whether the currently switched input device is the expected one until the television completes the processing
Solution Approach 1:
The television displays a preview image from each input interface before the user completes the switching operation. When the user presses the SWITCH button, the system immediately displays preview images from all available input interfaces on the screen, allowing the user to see what each interface contains before actually switching. This preliminary display of information eliminates the waiting time and allows the user to make an informed decision instantly.
2Ease of operation
If the television lists all input interfaces on a display to allow user selection, then the user can select the desired input interface, but it is very difficult for the user to intuitively determine the input interface that is expected to be switched to by only viewing identifiers
Solution Approach 1:
The television creates and displays a copy or preview of the image content from each input interface directly on the main display screen. Instead of only showing text identifiers like 'HDMI1' or 'AV', the system generates a visual copy of what each input device is currently displaying, allowing the user to intuitively identify the desired interface by its content rather than by abstract labels.
Solution Approach 2:
The system uses visual differentiation through color or highlight changes to indicate the currently selected or active input interface among the displayed previews. When the user navigates through the input interfaces using the remote controller, the corresponding preview image changes color or becomes highlighted, providing intuitive visual feedback about which interface is currently selected without requiring the user to read text identifiers.

AI summary
A method for switching an electronic device's input interface is provides, as well as a computer program product for performing the method. The method includes acquiring information from an input device through at least one input interface of the electronic device in response to receiving an input selection request from a user, and displaying the information to the user in association with a corresponding input interface. An electronic device is also provided, the electronic device including at least one input interface, a processor configured to acquire information from an input device through the at least one input interface in response to receiving an input selection request from a user, and a display operable to display the information to the user in association with a corresponding input interface.
