GUI Haptic Feedback Profiles for Accurate Blind Touch Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems lack effective haptic feedback mechanisms that differentiate between various types of graphical user interface (GUI) controls and operation positions, leading to inaccurate and inconvenient user interactions, particularly in scenarios like vehicle-mounted devices where precise operation is challenging due to limited visibility.
Innovation Solution
A display system that determines operation attribute information, including the type and position of touch operations on GUI controls, to generate tailored haptic feedbacks, such as varying vibration strengths and waveforms, to guide users in accurate interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If haptic feedback is provided for all touch operations uniformly, then user interaction is simplified, but operation accuracy and user guidance deteriorate
Solution Approach 1:
The patent applies local quality by providing different haptic feedback characteristics for different GUI control types and operation positions. Specifically, edge regions of controls generate stronger haptic feedback than central regions, and different control types (buttons, sliders, dials) have distinct feedback profiles. This localized differentiation maintains ease of operation while significantly improving operation accuracy and user guidance.
2Measurement precision
If haptic feedback differentiation is implemented for different control types and positions, then operation accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the haptic feedback system into multiple independent components: different feedback parameters for different control types (buttons, sliders, dials), different feedback strengths for different positions (edge vs. center), and configurable feedback profiles. This segmentation allows the complex functionality to be managed through modular parameter sets rather than a monolithic complex system.
Solution Approach 2:
The patent manages complexity through parameter changes by defining haptic feedback through adjustable parameters such as feedback strength, frequency, and waveform characteristics. Each GUI control type and position has associated parameter profiles that can be configured independently. This approach allows rich differentiation capability while maintaining system manageability through parameter-based control rather than structural complexity.
3Loss of information
If multiple haptic feedback parameters are adjusted for different operations, then user guidance is enhanced, but energy consumption increases
Solution Approach 1:
The patent applies partial action by providing haptic feedback only when necessary for operation guidance. Edge region feedback is triggered specifically when users interact with control boundaries, and different feedback parameters are activated based on the specific control type and operation context. This selective feedback approach enhances user guidance effectiveness while avoiding continuous or excessive energy consumption.
