Hybrid Absolute-Relative Touchpad Navigation for TV Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for navigating graphical user interfaces on television receivers require numerous input steps and are not intuitive, especially when using remote controls with position sensitive interfaces, as they often rely on absolute coordinate mapping which can be cumbersome for complex grid arrangements.
Innovation Solution
The system employs a method where initial absolute coordinate mapping on a television receiver's interface is followed by relative coordinate mapping, allowing for dynamic scaling to match various grid arrangements, enabling more efficient and intuitive navigation using a remote control's position sensitive interface.

Engineering Contradiction Analysis
1Ease of operation
If absolute coordinate mapping is used for navigation, then the mapping is straightforward and simple to implement, but the number of input steps increases and navigation becomes less intuitive
Solution Approach 1:
The system dynamically switches between absolute and relative coordinate mapping modes based on the navigation context. Initially, absolute mapping is used to establish the starting position, then relative mapping takes over for path traversal, allowing the mapping approach to adapt to different phases of the navigation task rather than using a fixed mapping method throughout
Solution Approach 2:
The coordinate mapping parameters are changed mid-navigation process. The system transitions from absolute coordinate parameters (where each touch point maps to a fixed screen location) to relative coordinate parameters (where touch movements map to directional movements from the current position), optimizing the mapping approach for the current navigation stage
2Adaptability or versatility
If absolute coordinate mapping is used, then the implementation is simpler, but it becomes cumbersome for complex grid arrangements
Solution Approach 1:
The navigation process is segmented into distinct phases: initial position establishment using absolute mapping, and subsequent path traversal using relative mapping. This segmentation allows each phase to use the most appropriate coordinate mapping approach, reducing the overall complexity for handling complex grid arrangements
Solution Approach 2:
The system introduces an intermediary processing layer that converts touch coordinates based on the current navigation context. This intermediary layer handles the complexity of coordinate transformation, shielding the user from the underlying mapping complexity while maintaining adaptability to various grid arrangements
3Measurement precision
If more remote control interactions are required for precise navigation, then the navigation accuracy improves, but the user experience deteriorates due to increased input steps
Solution Approach 1:
The system performs preliminary action by establishing the absolute starting position first, then uses relative coordinate mapping for subsequent movements. This preliminary establishment of position allows the user to navigate with fewer subsequent interactions, as each relative movement directly translates to navigation from the known starting point, improving both precision and user experience
