Jog Switch Display Device UI Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with multiple input buttons for adjusting functions, such as smart TVs, cause inconvenience for users as they need to search for specific buttons among many, especially when buttons are located on the side or rear surfaces.
Innovation Solution
A display device equipped with a jog switch that allows moving operations in multiple directions and push operations, enabling easy access and operation of various functions without needing to visually locate multiple buttons. The device displays user interfaces (UIs) on the screen in response to jog switch operations, allowing for channel, volume, and other function adjustments.
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 and operating the desired input button
Solution Approach 1:
The patent creates a virtual copy of the input button interface by displaying a function guide information window on the screen that shows the location and function of physical buttons. This allows users to see button positions and functions visually on the display without needing to physically locate and touch the buttons on the side or rear surface, effectively copying the control interface to a more accessible location.
Solution Approach 2:
The patent introduces a sensor as an intermediary that detects the user's hand approach and triggers the display of function guide information. This intermediary component bridges the gap between the user's intent to operate a button and the actual button location, providing guidance information that mediates the interaction between user and physical control elements.
2Loss of information
If the function guide information window is displayed through sensing of the user's hand, then the user can confirm button locations, but the user cannot operate the desired function because the displayed information does not correspond to the actual button operation
Solution Approach 1:
The patent implements feedback by having the sensor detect not only the user's hand approach but also the user's finger pressing action on the displayed function guide information window. When the user presses a specific button position on the displayed guide, the system provides feedback by executing the corresponding actual button function, creating a closed-loop interaction where the display and physical controls are synchronized.
Solution Approach 2:
The patent merges the virtual interface (displayed function guide information window) with the physical interface (actual input buttons) by making them correspond to each other. The displayed button positions and functions are merged with the actual physical button locations and functions, so that interacting with the visual representation directly controls the physical device functions.
3Adaptability or versatility
If multiple input buttons are provided for diverse functions, then the display device can perform more functions, but the user must spend more time finding the desired input button
Solution Approach 1:
The patent segments the control interface into two parts: physical buttons for actual control and a virtual function guide information window for information display and selection. This segmentation allows the diverse functions to be organized and displayed visually, enabling users to quickly locate desired functions on the screen without physically searching through multiple buttons on the device housing.
Solution Approach 2:
The patent makes the display screen universal by enabling it to serve multiple functions: displaying content, showing function guide information, and acting as a control interface. The same display component that shows video content also displays button location information and responds to user presses, eliminating the need for separate physical buttons for each function while maintaining access to diverse device capabilities.

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.
