Solution Overview

Problem

Existing visual interface systems face challenges in enhancing task highlighting while maintaining user awareness, leading to increased operator fatigue, particularly when using brain-machine interfaces that vary display attributes like icon colors between black and white.

Innovation Solution

A control system that oscillates display attributes at specific frequencies and harmonics to generate stimuli, toggling between pairs of states for an image layer until a response is detected, thereby preventing user fatigue and improving response accuracy.

1Productivity

If display attributes are varied at high frequency to enhance task highlighting, then user responsiveness is improved, but operator fatigue increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system applies periodic oscillation to display attributes (color, brightness, position) at specific frequencies to evoke visual evoked potentials (VEP) in the user's brain. By using periodic changes rather than continuous variation, the system stimulates neural responses that can be detected by EEG sensors, enabling brain-machine interface control while managing fatigue through controlled frequency selection.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system changes physical parameters of display attributes including frequency, amplitude, color spectrum, and temporal patterns to optimize VEP generation. By adjusting these parameters within specific ranges, the system maximizes neural response strength while avoiding frequencies that cause excessive fatigue, thus resolving the contradiction between responsiveness and operator comfort.

If display attributes are oscillated to generate visual stimuli, then task highlighting is enhanced, but user awareness is compromised

Engineering Contradiction:

Improvetask highlightingVSAvoiduser awareness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system applies oscillation selectively to specific display elements rather than the entire interface, and controls the amplitude and frequency within optimal ranges. This partial application of oscillation enhances task highlighting for critical elements while maintaining overall interface stability and user awareness, preventing the excessive stimulation that would compromise reliability.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system uses EEG feedback to monitor user neural responses in real-time and adjusts oscillation parameters accordingly. When VEP responses indicate sufficient awareness and engagement, the system maintains highlighting; when signs of fatigue or overload appear, the system reduces oscillation intensity, thus dynamically balancing task highlighting with user awareness.

Inventive Principle:

Principle #23Feedback

AI summary

System, methods, and other embodiments described herein relate to controlling display attributes within a visual interface for enhancing stimuli and responses of a user. In one embodiment, a method includes selecting display attributes related to a first layer of an image and a second layer of the image, wherein the image is associated with an interface to control a component. The method also includes oscillating, at a frequency, between first values of the display attributes for displaying the first layer. The method also includes oscillating, at a harmonic of the frequency, between second values of the display attributes for displaying the second layer in parallel with the first layer until detecting a selection associated with the interface.
