WildCard Icon for Remote Control Navigation Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in quickly selecting elements from lists displayed on a screen using remote controls with limited navigation keys, as the choice of navigation key is not always clear, leading to inefficiency and potential need for additional keys to manage page breaks.
Innovation Solution
Implementing a method that uses a 'WildCard' icon, allowing users to access additional functions and perform page jumps with a reduced number of keys, including a single key with multiple freedom movements, enabling efficient navigation and function activation without needing to look away from the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional navigation keys are added to manage page breaks and access functions, then navigation capability is improved, but remote control cost and complexity increase
Solution Approach 1:
The validation key is designed to perform multiple functions: selecting list elements, activating functions when an additional icon is present, and handling page breaks. This multi-functional design eliminates the need for separate dedicated keys for each operation, reducing remote control complexity while maintaining comprehensive navigation capability.
Solution Approach 2:
The system automatically detects the presence of an additional icon and adjusts the validation key's function accordingly. When the additional icon is highlighted, the validation key activates functions or page breaks without requiring separate navigation instructions, allowing the system to serve itself based on the current display state.
2Productivity
If more navigation keys are provided for page breaks, then list navigation efficiency is improved, but manufacturing cost increases
Solution Approach 1:
The validation key serves as a universal control that handles both element selection and page break navigation. When the additional icon is highlighted, pressing the validation key performs page breaks or activates functions, eliminating the need for separate page navigation keys and reducing manufacturing costs.
Solution Approach 2:
The function of the validation key dynamically changes based on the highlight position. It can select list elements or perform page breaks/activate functions depending on whether the additional icon is highlighted, allowing a single static key to perform multiple dynamic functions without requiring additional physical keys.
3Adaptability or versatility
If traditional navigation methods are used with scattered boxes, then display flexibility is improved, but user selection speed decreases
Solution Approach 1:
The system provides visual feedback by displaying an additional icon that clearly indicates the presence of accessible functions. This feedback mechanism guides users on what actions are available, reducing cognitive load and selection time while maintaining the flexible scattered box display arrangement.
Solution Approach 2:
The additional icon acts as an intermediary visual cue between the list elements and the available functions. It mediates the user's understanding of what operations are possible from the current position, enabling faster decision-making without changing the flexible display layout.

AI summary
The method involves selecting an item by graphically highlighting its icon triggered by receiving a command, and executing a function applied to the item selected triggered by receiving another command. Additional icons identifying functions are displayed, and the additional icons are highlighted triggered by receiving a third command. An identifier of one of the identified functions is displayed and highlighted following a specified period during which no command is received. The execution of the function whose identifier is highlighted modifies the sub-set of displayed items. An independent claim is also included for an electronic device for implementing an item and function selecting method.
