Adaptive Tactile Feedback Control for Touch Display Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with tactile user interfaces cannot adaptively generate tactile feedback in response to user control operations, limiting their effectiveness in providing responsive and intuitive interaction.
Innovation Solution
A display device comprising a touch-sensitive display unit, a tactile feedback unit, and a controller that detects user touches and generates tactile feedback based on object properties, allowing adaptive and continuous feedback during control operations, even when moving between objects or regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional tactile user interface generates constant tactile feedback, then the feedback is simple to implement, but it cannot adaptively respond to user control operations
Solution Approach 1:
The system implements a feedback mechanism where the tactile feedback unit generates feedback signals based on detected touch gestures and control operations. The controller receives detection results from the touch-sensitive display unit and sends control signals to the tactile feedback unit, creating a closed-loop feedback system that adapts to user interactions dynamically
Solution Approach 2:
The tactile feedback system transitions from static constant feedback to dynamic adaptive feedback. The feedback characteristics (intensity, frequency, pattern) are modified in real-time based on the type of control operation being performed, making the system responsive and adaptable to different user interactions
2Ease of operation
If tactile feedback changes with each control operation, then user interaction becomes more intuitive, but the system complexity increases
Solution Approach 1:
The tactile feedback unit serves multiple functions by generating different types of feedback for different control operations using a single integrated component. The same tactile feedback unit provides feedback for selection, movement, confirmation, and cancellation operations, reducing the need for multiple specialized components while maintaining operational intuitiveness
3Ease of operation
If the display device provides visual user interface only, then the device structure remains simple, but user interaction lacks tactile responsiveness
Solution Approach 1:
The system merges the visual display function with tactile feedback function into an integrated user interface system. The touch-sensitive display unit and tactile feedback unit work together as a unified interface, combining visual and tactile modalities to enhance user interaction without requiring separate independent systems

AI summary
Disclosed is a display device that provides a user with tactile feedback using a tactile user interface. The display device includes a touch sensitive display unit to display an object, a tactile feedback unit to generate tactile feedback, and a controller. The controller detects a first touch that is in contact with a region of a first object displayed on the display unit, detects a second touch controlling the first object that is consecutive to the first touch, controls the first object in response to the second touch, generates first tactile feedback according to properties of the first object in response to the second touch, detects a third touch controlling the first object that is consecutive to the second touch, the third touch being detected in a region of a second object displayed on the display unit, and generates the first tactile feedback in response to the third touch.
