Vehicle Navigation Cues Through Light, Sound, and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems are distracting and complex due to map-based displays and voice directions, requiring significant cognitive load from drivers, as they often include overwhelming landmark descriptions and multiple controls, which can divert attention from the road.
Innovation Solution
A method and system that converts navigation direction data into electrical communications for vehicle components such as light, sound, and vibration indicators, providing simplified real-time navigation directions by transmitting these signals to the vehicle components, reducing the need for traditional map-based and voice navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional map-based displays and voice directions are used, then navigation information is provided to drivers, but cognitive load increases and driver attention is diverted from the road
Solution Approach 1:
The patent replaces traditional visual map displays and voice directions with a haptic feedback system that uses the steering wheel as a tactile interface. The navigation system translates directional information into tactile cues through the steering wheel, allowing drivers to receive navigation guidance through touch rather than sight or sound, thereby reducing cognitive load and maintaining visual attention on the road.
Solution Approach 2:
The steering wheel serves as an intermediary device between the navigation system and the driver. Instead of directly presenting map images or voice instructions, the system uses the familiar steering wheel as a mediator to convey navigation directions through haptic feedback patterns, making the information delivery more intuitive and less distracting.
2Loss of information
If traditional map-based displays are used, then navigation directions are provided, but driver distraction increases and safety decreases
Solution Approach 1:
The system substitutes visual and auditory navigation channels with tactile feedback through the steering wheel. By encoding navigation directions in haptic patterns that the driver feels while maintaining normal steering control, the system delivers navigation information without requiring the driver to shift visual or auditory attention from the driving task.
Solution Approach 2:
The steering wheel, which the driver is already in contact with and controlling, serves dual purposes: it remains the primary control device for steering while simultaneously functioning as a navigation information display. This eliminates the need for separate navigation interfaces that would compete for the driver's attention.
3Loss of information
If multiple navigation controls and landmark descriptions are provided, then comprehensive navigation information is available, but system complexity increases
Solution Approach 1:
The patent extracts only the essential navigation directional information (turn left, turn right, go straight) and presents it through simplified haptic patterns. Complex landmark descriptions and detailed map data are removed from the driver interface, with only the critical steering-related navigation cues being transmitted through the steering wheel.
Solution Approach 2:
The system applies different haptic feedback patterns to different regions or aspects of steering wheel interaction based on the specific navigation need. Each tactile pattern is locally optimized to convey a specific directional instruction, creating a simplified yet comprehensive navigation communication system that adapts to the immediate navigation context.
Data Source
AI summary
A method for automatically providing real-time navigation directions using one or more vehicle components is provided. The method may further include, in response to receiving and identifying navigation direction data from a navigation service provider, converting the navigation direction data into different electrical communications to different vehicle components that may include one or more combinations of a light indicator component, a sound indicator component, and a vibration indicator component associated with a vehicle. The method may also include automatically presenting the real-time navigation directions using the different vehicle components by automatically transmitting the electrical communications based on the navigation direction data to the one or more combinations of the light indicator component, the sound indicator component, and the vibration indicator component.
