Scroll Bar Channel Selection Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing channel-changing methods, such as using channel-up or channel-down keys, require repeated key presses for multiple channel changes, and direct channel number input or channel lists require users to memorize channel numbers, making channel manipulation inefficient and user-unfriendly.
Innovation Solution
A display device with a processor that displays a scroll bar with moving cursor and adjacent channel information upon user input, allowing rapid channel selection by moving the cursor on a scroll bar with varying speeds and displaying additional UI for channel details, enabling intuitive channel selection and transmission to external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If channel-up or channel-down keys are used to change channels, then channel selection is possible, but repeated key presses are required for multiple channel changes, reducing operation efficiency
Solution Approach 1:
The system pre-generates a channel map storing channel information in advance, and when a user inputs a channel number, the system automatically searches and selects the corresponding channel from the pre-stored map, eliminating the need for manual sequential channel switching
Solution Approach 2:
A channel map data structure serves as an intermediary between the user's channel number input and the actual channel switching operation, enabling direct mapping and rapid channel selection without repeated key presses
2Ease of operation
If direct channel number input or channel list display is used, then channel selection is possible, but users must memorize channel numbers, increasing operation difficulty
Solution Approach 1:
The system displays a user interface showing the current channel number and program information in real-time, providing visual feedback that helps users identify and select channels without needing to memorize channel numbers
Solution Approach 2:
The system automatically manages channel information display and selection based on user input, eliminating the need for users to manually memorize or search through channel lists
3Ease of operation
If a scroll bar with multiple channel points is displayed, then visual channel selection is possible, but the interface may become cluttered, reducing display clarity
Solution Approach 1:
The channel selection interface is segmented into distinct functional areas: a scroll bar for channel navigation, a cursor for selection indication, and an information display area for channel details, allowing each element to be optimized independently without cluttering the overall interface
Solution Approach 2:
The interface utilizes multiple display dimensions by showing channel information in both the scroll bar (visual positioning) and the information display area (detailed text), providing redundant information presentation that enhances clarity without crowding any single area

AI summary
A display device is provided. The display device includes a first communication interface receiving broadcast content, a second communication interface which receives a user input, a display, and a processor electrically connected with the display, the first communication interface, and the second communication. The processor controls the display to display a first user interface (UI) including a scroll bar including a plurality of points corresponding to a plurality of channels, a cursor moving on the scroll bar depending on the user input, and information on a channel corresponding to a point at which the cursor is displayed, if the second communication interface receives a preset user input. The processor is controls the display to additionally display a second UI including information on one or more channels adjacent to the channel corresponding to the point at which the cursor is displayed, if the preset user input is stopped.
