Touch Remote Visual Feedback for Accurate Icon Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch-sensitive displays on portable electronic devices lack tactile or non-visual sensory feedback, leading to user errors when interacting with virtual icons, especially in situations where direct visual access is not possible, such as in poor lighting or when the device is obstructed.
Innovation Solution
An audio/video hub that receives user-interface activity information from a portable electronic device and generates visual feedback indicating the position of a touch contact point relative to virtual command icons on an A/V display device, allowing users to navigate the interface intuitively without direct visual attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch-sensitive display is used for remote control, then device versatility and wireless communication capability are improved, but tactile feedback and user interaction accuracy deteriorate
Solution Approach 1:
The patent implements visual feedback by displaying indicators on the A/V display device that show the position of touch contact points relative to virtual command icons. This feedback loop allows users to see where they are touching on the remote control device, enabling accurate interaction without direct visual attention to the touch-sensitive display itself.
Solution Approach 2:
The A/V display device serves as an intermediary between the portable electronic device and the user. Instead of requiring the user to directly view the touch-sensitive display, the system mediates the interaction by projecting touch position feedback onto the A/V display device, which the user can see without needing to look at the remote control.
2Measurement precision
If direct visual access to touch-sensitive display is required, then user interaction accuracy is improved, but user convenience and accessibility deteriorate
Solution Approach 1:
The system provides visual feedback by displaying the touch contact point position on the A/V display device. This allows users to maintain spatial awareness of their finger position relative to virtual command icons without needing to directly view the touch-sensitive display, enabling accurate activation while maintaining convenience.
Solution Approach 2:
The patent moves the visual feedback from the two-dimensional touch-sensitive display surface to the A/V display device display surface. This dimensional shift allows users to see touch position information in a different spatial context, enabling accurate interaction without direct visual access to the original display.
3Loss of information
If visual feedback is provided on A/V display device, then user spatial awareness is improved, but system complexity increases
Solution Approach 1:
The A/V display device is utilized for dual purposes: displaying regular A/V content and providing touch position feedback. By making the existing display serve multiple functions, the system provides spatial awareness information without adding dedicated feedback hardware, thus limiting the increase in system complexity.
Solution Approach 2:
The patent combines the feedback function with the existing A/V display device. Instead of creating a separate feedback mechanism, the system merges the touch position indication functionality with the already-present display capabilities, reducing overall system complexity while maintaining information delivery.

AI summary
An audio/video (A/V) hub provides feedback to a user of a portable electronic device with a touch-sensitive display (such as a cellular telephone) that is used as a wireless remote control for an audio/video (A/V) display device, the A/V hub and/or a consumer-electronic device. In particular, when the A/V hub receives, from the portable electronic device, user-interface activity information associated with a user interface displayed on a touch-sensitive display, the A/V hub generates visual feedback based on the user-interface activity information. Then, the A/V hub provides the visual feedback to the A/V display device for display on the A/V display device. The visual feedback indicates a position of at least a touch contact point of a user of the portable electronic device relative to a strike area of at least a virtual command icon in the user interface.
