Jog Dial Remote Control for Program Selection Without Keypad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control devices for television receivers lack operability when selecting programs without a numerical keypad, requiring multiple operations to choose a program, and existing solutions do not directly allow program list selection from a full-screen video display.
Innovation Solution
A video display device and method using a remote control with a jog dial for rotational operations to display a program list alongside the video, allowing users to select programs with a single operation by rotating the jog dial, and displaying a program search figure to facilitate program selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a numerical keypad is removed from the remote control device to minimize it, then the device size is reduced, but the ability to select programs efficiently is worsened
Solution Approach 1:
The jog dial is designed to perform multiple functions: it can rotate to scroll through program lists, press to confirm selections, and serve as the primary interface for program selection without requiring a numerical keypad. This multi-functional design allows the remote control to maintain program selection capability while minimizing its size.
Solution Approach 2:
The television receiver's display screen acts as an intermediary by showing program information and thumbnails directly. This allows users to select programs visually from the displayed content rather than inputting channel numbers, eliminating the need for a numerical keypad while maintaining ease of operation.
2Volume of moving object
If a numerical keypad is not provided in the remote control device, then the device is minimized, but multiple operations are required to select a program
Solution Approach 1:
The system prepares program information, including thumbnails and metadata, in advance and displays it on the television screen. When a user rotates the jog dial, the corresponding program information is immediately displayed, allowing for quick selection without requiring multiple sequential operations or manual channel number input.
Solution Approach 2:
The television display provides immediate visual feedback by showing program thumbnails and information corresponding to the jog dial's rotation position. This real-time feedback allows users to see the result of their rotation operation instantly and make informed selection decisions, reducing the time and number of operations needed to select a program.
3Ease of operation
If a program list is displayed on the television screen during video playback, then program selection becomes easier, but the video display area is reduced
Solution Approach 1:
The display screen is segmented into different regions: the main video playback area and a program information display area. The program list or thumbnail information is displayed in a separate segment, allowing users to select programs while the video continues to play. This segmentation enables both video viewing and program selection to occur simultaneously without completely blocking the video display.
Solution Approach 2:
Program information is displayed in a different spatial dimension or layer on the screen, such as overlaying semi-transparent program information on the video or displaying thumbnails in a compact format at the screen edges. This dimensional arrangement allows program selection information to be presented without significantly reducing the effective video display area.

AI summary
Provided are a video display device and a video display method, by which a user can easily select a program to be watched even if a numerical keypad is not provided in a remote control device. A display portion displays a video of a program. While the video of the program is displayed on the full screen of the display portion, an operation detection portion detects a rotational operation of a dial provided in a remote control device. When the rotational operation is detected by the operation detection portion, a control portion functions so that while the video of the program is displayed on the display portion, a program list including a plurality of program items associated with different programs is displayed on the display portion.
