Haptic Feedback Manager for Touch Input Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices face challenges in comprehensively incorporating haptic feedback across different applications and services that do not have the ability to invoke haptic mechanisms, limiting the usability of haptic feedback in various scenarios.
Innovation Solution
The implementation of a system and method that enables haptic feedback on touch input devices by determining whether an application or operating system supports haptic feedback, allowing haptic feedback to be generated even if it is not directly supported, through the use of a haptic module that recognizes user input and attributes of gestures to produce predefined haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If haptic feedback is implemented only in applications that directly support it, then the implementation is simple and reliable, but the versatility and comprehensiveness of haptic feedback coverage is limited
Solution Approach 1:
The patent introduces an intermediary component (haptic feedback manager or system-level interface) that sits between applications and the haptic mechanism. This intermediary translates generic user input events into haptic feedback commands, enabling applications that do not directly support haptic feedback to still benefit from it. The intermediary handles the complexity of haptic control while applications maintain their原有 simplicity.
Solution Approach 2:
The patent creates a universal haptic feedback system that can serve multiple types of applications regardless of their native haptic support. By implementing a system-level haptic interface that monitors and responds to user inputs across all applications, the solution enables haptic feedback coverage throughout the entire system, making the haptic mechanism universally applicable rather than application-specific.
2Reliability
If haptic feedback is provided for all user inputs regardless of application support, then the user experience consistency is improved, but the difficulty of integrating with legacy systems increases
Solution Approach 1:
The intermediary haptic feedback manager acts as a bridge between legacy systems and the haptic mechanism. It intercepts user input events at the system level and generates appropriate haptic feedback without requiring modifications to legacy applications. This approach maintains user experience consistency while preserving compatibility with existing systems that were not designed with haptic support.
Solution Approach 2:
The system implements preliminary action by establishing a system-level haptic feedback framework before applications need to use it. The haptic feedback manager is pre-configured to monitor user inputs and trigger haptic responses, so when legacy applications run, they automatically benefit from haptic feedback without requiring any preliminary integration work on their part.

AI summary
Techniques for haptic feedback for a touch input device are described. Generally, haptic feedback is provided for different user interactions with a touch input device, such as interactions with applications, services, and so forth. According to various embodiments, how haptic feedback is initiated depends on whether different functionalities directly support haptic feedback. For instance, techniques described herein enable haptic feedback to be provided whether or not a particular functionality directly supports haptic feedback.
