Context-Aware Haptic Feedback Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices face inconvenience in controlling haptic feedback, as existing systems require users to exit applications to adjust settings, disrupting the experience, especially when enjoying audio or video content.
Innovation Solution
A system that dynamically controls haptic feedback based on the device's context, allowing users to interact with a haptic control user interface only when appropriate, adjusting parameters such as strength, density, and sharpness through a user-friendly interface, without interrupting ongoing media or communication contexts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users can control haptic feedback parameters at any time, then ease of operation is improved, but interruption of ongoing media or communication contexts occurs
Solution Approach 1:
The system dynamically adjusts the availability of haptic control based on the current device context. The haptic control user interface is conditionally displayed or hidden depending on whether the current application or media context is appropriate for haptic adjustment, allowing the interface to adapt its behavior to different usage scenarios rather than being static
Solution Approach 2:
The system introduces a context determination mechanism that acts as an intermediary between the user's control requests and the haptic feedback system. This intermediary evaluates whether the current context permits haptic control adjustments and mediates the display of the control interface accordingly, preventing direct interruptions while maintaining control capability when appropriate
2Ease of operation
If haptic control interface is always displayed, then user control capability is improved, but device complexity increases
Solution Approach 1:
The system extracts the haptic control interface from the permanent visible interface and makes it contextually available only when needed. By conditionally displaying the haptic control user interface based on context determination, the system removes the unnecessary burden of always-present controls while maintaining accessibility when appropriate

AI summary
A feedback control system is provided. The feedback control system receives a user input. The feedback control system determines a context. The feedback control system displays a control in response to the user input and based on the context. The feedback control system adjusts a feedback parameter according to the control, where the control is configured to adjust feedback output to a user based on the adjusted feedback parameter.
