Human-Machine Interface Control for Adaptive Sensory Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots and air traffic controllers face challenges in processing a high volume of information from various sensory channels during critical situations, leading to potential loss of important information due to reduced sensory bandwidth, especially under stress or environmental distractions.
Innovation Solution
A system and method that measure physiological conditions to determine sensory bandwidth, selectively delivering information through visual, aural, or haptic channels based on the user's capacity to process, using sensors like brain activity and eye movement monitors, and adjusting information presentation to optimize acknowledgment and response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple sensory channels are used to deliver information simultaneously, then information delivery capacity is improved, but user processing capacity deteriorates under stress
Solution Approach 1:
The system dynamically adapts information delivery by monitoring physiological conditions (heart rate, pupil dilation, skin conductance) to determine user stress levels and sensory bandwidth in real-time. The information delivery system adjusts channel selection and presentation parameters based on continuous physiological feedback, transitioning from static to dynamic operation to match user capacity
Solution Approach 2:
The system changes physical parameters of information delivery by selecting different sensory channels (visual, aural, haptic) based on measured physiological parameters. When stress increases, the system modifies delivery parameters by switching to channels with higher available bandwidth, such as using haptic feedback or simplified visual displays instead of complex audio streams
2Loss of information
If information is delivered through multiple sensory channels simultaneously, then information completeness is improved, but user attentional resources deteriorate
Solution Approach 1:
The system segments information delivery across different sensory channels based on user physiological state. Instead of flooding all channels simultaneously, it divides information into priority levels and assigns appropriate channels, ensuring critical information reaches the user through their most available sensory pathway at any given moment
Solution Approach 2:
The system incorporates feedback loops where physiological sensors continuously monitor user state, and this feedback informs real-time adjustments to information delivery. The system detects when a user is overwhelmed by physiological indicators and automatically reduces information load or switches channels to maintain effectiveness
3Speed
If sensory bandwidth is increased through multiple channels, then information processing speed is improved, but user stress levels worsen
Solution Approach 1:
The system serves itself by automatically monitoring physiological conditions and adjusting information delivery without requiring user input or awareness. The physiological sensors and processing system work autonomously to optimize information delivery based on real-time stress indicators, freeing the user from manual control while adapting to their state
