Motion-Controlled Display Channel Navigation via Variable Step Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion recognition technologies in display devices require users to perform numerous repetitive motions to navigate through multiple channels or pages, leading to inconvenience and potential arm fatigue, especially when dealing with large numbers of channels or content pages.
Innovation Solution
A display apparatus and method that incorporates a motion recognition unit to recognize user motions and a control unit that adjusts operation performance based on motion speed and distance, allowing for variable and incremental changes in channel or page selection, such as changing channels or shifting pages by different amounts depending on motion speed and distance, with threshold values determining the change amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion recognition technology is used to control channel change in one channel unit, then channel selection precision is improved, but the number of required user motions increases significantly when selecting channels far from current position
Solution Approach 1:
The patent applies parameter changes by making the channel change amount variable based on motion characteristics. Specifically, the channel change amount is determined according to the motion distance traveled by the user's hand, allowing larger channel jumps for longer motions and smaller jumps for shorter motions. This resolves the contradiction by maintaining precise control while reducing the number of required motions for distant channel selections.
2Ease of operation
If motion recognition technology is used for menu navigation, then operation convenience is improved, but arm fatigue increases when navigating through large numbers of channels or pages
Solution Approach 1:
The patent changes the parameter of operation magnitude by dynamically adjusting the menu navigation step size based on motion distance. Users can navigate through multiple channels or pages with a single motion by having the system interpret the motion distance as the number of steps to skip, thereby maintaining ease of operation while significantly reducing arm fatigue.
Solution Approach 2:
The patent applies partial action by allowing users to perform only the necessary motion to achieve their desired navigation target. Instead of requiring users to step through each menu item individually, the system enables users to make partial progressions through larger jumps when their motion distance indicates intent to skip multiple items, reducing the total action required.
3Device complexity
If fixed channel change amount is used for motion control, then control simplicity is improved, but adaptability to different user intentions decreases
Solution Approach 1:
The patent applies dynamics by making the channel change amount adjustable rather than fixed. The system dynamically determines the change amount based on the motion distance detected from user input. This allows the control system to adapt to different user intentions and preferences while maintaining relatively simple operation, resolving the contradiction between simplicity and adaptability.

AI summary
A display apparatus is provided, which includes a motion recognition unit which recognizes a motion of an object that is located outside the display device, and a control unit which, when the motion of the object is recognized, determines a change amount that varies according to a motion speed or a motion distance of the object, and performs an operation which corresponds to the motion of the object according to the change amount. Accordingly, channel change or page shift can be easily performed.
