Wearable Haptic Feedback for ADAS Driver Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive systems rely on visual and auditory notifications that can distract drivers and passengers, as they require attention away from the road to process information, and do not provide easy access to information for multiple vehicle occupants.
Innovation Solution
A system using wearable devices that receive wireless signals from a processor in the vehicle to generate haptic feedback, providing supplementary information without the need for visual or auditory attention, allowing customizable feedback for multiple passengers and reducing driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual notifications (screens, meters, lights) are used to alert drivers, then information can be provided to the driver, but driver distraction increases as the driver must look away from the road
Solution Approach 1:
The notification system is segmented into multiple independent feedback channels: visual feedback through dashboard displays and haptic feedback through wearable devices. This segmentation allows information to be delivered through different modalities simultaneously, so the driver receives critical alerts through haptic cues on the steering wheel while maintaining visual attention on the road, thus resolving the contradiction between information delivery and driver focus
Solution Approach 2:
A wearable device worn by the driver acts as an intermediary between the vehicle's notification system and the driver. This intermediary translates visual notifications into haptic feedback patterns that the driver can perceive through touch while keeping eyes on the road, effectively mediating the information delivery process without requiring direct visual attention to dashboard displays
2Loss of information
If touchscreen displays with various interfaces are used to provide information, then rich information can be presented, but driver distraction increases further
Solution Approach 1:
The information presentation is segmented across multiple devices and modalities: complex information can be displayed on touchscreen interfaces for detailed viewing when needed, while critical alerts are segmented into separate haptic notifications that provide immediate tactile feedback without requiring visual engagement with the display, thus maintaining information richness while reducing distraction
Solution Approach 2:
Instead of presenting all information through visual displays, the system uses partial action by delivering only essential alerts through haptic feedback, while more detailed information remains available on displays for when the driver chooses to review it. This partial delivery of information through multiple channels reduces the cognitive load and visual attention required during driving
3Loss of information
If traditional feedback systems are used, then information can be provided, but access to information is difficult for multiple vehicle occupants
Solution Approach 1:
The wearable device serves multiple functions: it provides haptic feedback to the driver, can be worn by any occupant to receive vehicle status information, and works with various vehicle types. This multi-functionality allows any occupant wearing the device to access vehicle information through haptic cues, making the system universally accessible rather than limited to dashboard viewing positions
Solution Approach 2:
The system transitions from two-dimensional visual displays on the dashboard to three-dimensional haptic feedback that can be perceived through touch and body position. This dimensional change allows occupants to receive information through tactile sensations regardless of their seating position or orientation in the vehicle, making information accessible to all occupants without requiring them to look at or reach for dashboard 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
The system effectively supplements primary feedback systems by providing tactile information that is faster and more responsive, allowing drivers and passengers to remain focused on the road while being aware of vehicle status and alerts, and can be customized for various vehicles and scenarios.

AI summary
The invention concerns a system comprising a processor and a device. The processor may be configured to (i) analyze one or more vehicle systems and (ii) generate a first output signal and a second output signal corresponding to the vehicle systems. The device may be configured to (i) receive the second output signal and (ii) generate haptic feedback based on the second output signal. The first output signal is presented to enable feedback using a primary feedback device. The device may be worn by a user. The haptic feedback supports information provided by the primary feedback device. The second output signal is communicated to the device using wireless communication.
