Symbol Queue Scrolling with Synchronized Visual-Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices lack effective methods to provide synchronized visual and haptic feedback during user interface scrolling, leading to a less immersive and engaging user experience, especially when users are unable to visually perceive the scrolling process.
Innovation Solution
A method and system that animates symbols in a symbol queue on a screen while generating synchronized haptic feedback when a threshold of visual content is displayed, using haptic pulses to enhance user interaction during scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual feedback is provided during scrolling, then user interface information is communicated, but user experience is insufficient when visual feedback is obscured
Solution Approach 1:
The patent introduces haptic feedback as an intermediary channel to convey scrolling information when visual feedback is unavailable or insufficient. The haptic pulses serve as a mediator between the scrolling action and user perception, allowing users to sense scrolling progress through tactile sensations even when visual feedback is obscured or unavailable.
2Ease of operation
If haptic feedback is added to scrolling, then user experience is enhanced, but device complexity increases
Solution Approach 1:
The patent merges visual and haptic feedback systems into a unified multi-sensory feedback mechanism. By combining these feedback modalities and synchronizing them, the system enhances user experience while managing complexity through integration rather than separate independent systems.
Solution Approach 2:
The haptic feedback is implemented as periodic pulses synchronized with the scrolling animation. This periodic action provides rhythmic tactile feedback that corresponds to the visual scrolling progress, creating a predictable and manageable feedback pattern that reduces system complexity through regular intervals.
3Reliability
If haptic pulses are synchronized with visual animation, then feedback effectiveness is improved, but control complexity increases
Solution Approach 1:
The system implements synchronized feedback where haptic pulses are triggered based on the state of visual animation during scrolling. The haptic feedback loop is coordinated with visual feedback, creating a unified multi-sensory experience where both feedback types reinforce each other through temporal synchronization.

AI summary
Apparatus and methods related to visual and haptic feedback on mobile devices are provided. A computing device can present a symbol queue that includes a particular symbol on a screen. The computing device can receive user input to move through the symbol queue. In response to the user input, the computing device can: animate the particular symbol on the screen by at least presenting an expanded item display that includes at least the particular symbol and a particular informational item associated with the particular symbol, and generate haptic feedback that is synchronized with animating the particular symbol on the screen.
