Single Controller for Multi-Display Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems require multiple dedicated controllers for various displays, which increases complexity, cost, and reduces usability, as drivers must manually switch between displays, taking their eyes off the road to do so.
Innovation Solution
A single controller system that integrates multiple displays and provides haptic feedback to allow drivers to switch between them without looking away, using a user interface with input devices like touch pads and haptic output devices for vibrotactile and friction effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple dedicated controllers are used for different displays, then each display can be controlled independently, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple dedicated controllers into a single integrated controller that can control multiple displays. The controller includes a processor that receives inputs and determines which display should receive control based on contextual factors, merging the functionality of what would traditionally require separate controllers.
Solution Approach 2:
The single controller is designed with universal functionality to control multiple different displays (instrument cluster, infotainment, head-up display). The controller can adapt its behavior based on which display is currently active, making one device perform the roles of multiple dedicated controllers.
2Measurement precision
If drivers manually switch between displays, then control precision is maintained, but driver attention is lost from the road
Solution Approach 1:
The system provides self-service by automatically determining which display should receive control based on the driver's needs and contextual information. The controller monitors various inputs and automatically switches control between displays without requiring the driver to manually intervene, making the system serve itself rather than requiring continuous driver attention.
Solution Approach 2:
The controller uses feedback from multiple sources (user inputs, sensor data, display states) to automatically determine which display should receive control. This feedback mechanism allows the system to adapt to the driver's needs and maintain control precision without requiring the driver to visually monitor and manually switch between displays.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances usability by allowing single-handed control of multiple vehicle displays, reducing driver distraction and enabling new GUI designs, while minimizing hardware and space requirements.
Implementation Method 1
generating a first haptic effect to confirm receipt of the first input
Implementation Method 2
the second haptic effect is a friction effect
Data Source
AI summary
A method includes displaying information via a first display, displaying information via a second display, controlling the information displayed via the first display and the second display with a controller, and receiving a first input from a user through a user interface. The first input includes a command to change a setting of the first display or the second display and/or the information being displayed via the first display or the second display. The method also includes generating a first haptic effect to confirm receipt of the first input.
