Jog Switch Control for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in operating display devices with numerous input buttons, especially when they are not visible and require guidance through sensing, leading to difficulty in finding the correct button for adjusting functions.
Innovation Solution
A display device equipped with a jog switch that allows for moving and push operations, displaying User Interfaces (UIs) for channel, volume, and other function adjustments, enabling users to easily operate the device without needing to see the buttons, facilitating miniaturization and polished designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple input buttons are arranged on the side surface or rear surface of the display device, then the design can be miniaturized and polished, but the user experiences inconvenience in finding the correct button for adjusting functions
Solution Approach 1:
The patent implements a feedback mechanism where a sensor detects the user's hand approach and displays function guide information on the screen. This visual feedback helps users identify which button to press by showing the corresponding function, thereby resolving the contradiction between miniaturized design and ease of operation.
Solution Approach 2:
The patent introduces an intermediary system consisting of a sensor and display unit that mediates between the hidden buttons and the user. The sensor detects hand presence and the display shows function guides, creating an intermediate communication channel that helps users operate the device without seeing the buttons directly.
2Loss of information
If function guide information is displayed through sensing of the user's hand, then the user can confirm button locations, but the information displayed does not correspond to the button the user actually intends to operate
Solution Approach 1:
The patent makes the jog switch universal by enabling it to perform multiple functions: directional movement for navigating menu options and push operation for selecting/confirming. This multi-functionality allows a single control element to replace multiple buttons, resolving the information mismatch problem.
Solution Approach 2:
The patent adds a temporal dimension to the control interface by requiring a prolonged push operation (exceeding a threshold time) to activate function guides. This time-based differentiation allows the system to distinguish between casual touching and intentional activation, improving information accuracy.
3Device complexity
If a jog switch with moving and push operations is used, then a single control can operate various functions, but the device complexity increases
Solution Approach 1:
The patent merges multiple control functions into a single jog switch. The switch combines directional movement capabilities (for navigating up, down, left, right) with push functionality (for selection and confirmation), thereby reducing the number of separate buttons while maintaining functional versatility.
Solution Approach 2:
The jog switch is designed as a universal control element that can perform multiple operations: directional navigation and push selection. This multi-functionality allows one component to replace what would traditionally require multiple separate buttons, achieving both simplification and versatility.

AI summary
A display device is provided, which includes a jog switch which performs a moving operation in a plurality of directions and a push operation, a display unit which displays a first user interface (UI) for adjusting a channel or a volume of the display device or a second UI for adjusting other functions of the display device in accordance with a first operation of the jog switch, and a control unit which adjusts a selected function of the display device in accordance with a second operation of the jog switch in which is performed in a state where the first UI or the second UI is displayed. The jog switch is formed to project for a predetermine height from a surface of the display device, and thus a user can find the jog switch easily and promptly even is the jog switch is obstructed from view.
