Dual Cursor Control for Remote Navigation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating a cursor on an electronic device, such as a TV, using a remote controller with sensors like a touchpad or joystick is difficult due to the lack of clear feedback on the extent of swipe operations, leading to uncertainties in cursor movement.
Innovation Solution
A control device and method that display a first cursor which discretely moves in response to user operations and a second cursor that continuously changes on the screen, providing visual feedback through a combination of cursors to enhance operability, especially when using a remote controller with touchpad or joystick.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single cursor is displayed on the screen, then the display is simple, but the user cannot clearly recognize the extent of swipe operations and operates the cursor with difficulty
Solution Approach 1:
The patent divides the cursor into two distinct types: a first cursor that moves discretely in response to swipe operations and a second cursor that moves continuously to indicate the exact position of swipe operations. This segmentation allows each cursor to serve a specific function - the first cursor provides discrete selection feedback while the second cursor provides continuous position feedback, together solving the problem of cursor operation clarity without overcomplicating the display.
Solution Approach 2:
The patent implements a feedback mechanism where the second cursor continuously tracks and displays the precise position of swipe operations on the screen, providing real-time visual feedback to the user about the extent of their swipe operations. This feedback loop helps users understand the relationship between their input actions and cursor movement, making the cursor operation more intuitive and controllable.
2Measurement precision
If the cursor moves continuously to show precise position, then the user can see the exact location, but the cursor cannot provide clear discrete selection feedback
Solution Approach 1:
The patent segments the cursor functionality into two distinct cursors with different behaviors: the first cursor moves discretely to provide clear selection feedback when items are selected, while the second cursor moves continuously to show precise position indication. This segmentation allows both functions to coexist without interfering with each other, resolving the contradiction between precision and discrete feedback.
Solution Approach 2:
The patent applies different quality characteristics to different parts of the cursor system: the first cursor uses discrete movement quality for selection feedback, while the second cursor uses continuous movement quality for position indication. Each cursor type has optimized local characteristics suited to its specific function, allowing the system to provide both precise position information and clear discrete feedback simultaneously.
