Eye Tracking Interface for Flight Deck Workload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight deck systems require multiple steps and high workload for users to complete tasks due to complex user interface control devices, and voice recognition systems lack sufficient accuracy for reliable use.
Innovation Solution
Implementing an eye tracking system that detects a user's gaze and correlates it with items on a display, allowing for reduced input steps through an integrated processor and input device, which can also support voice commands by providing context for improved recognition accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interface control devices are used in flight deck systems, then the system can provide comprehensive control functions, but the user workload increases and task completion requires multiple steps
Solution Approach 1:
The patent replaces traditional mechanical control devices (mouse, keyboard, touch screen) with an eye tracking system that uses optical detection to identify user intent. The eye tracking sensor detects gaze direction and correlates it with display items, eliminating the need for physical cursor manipulation and reducing mechanical interaction steps.
Solution Approach 2:
The patent introduces voice recognition as an intermediary between the user and the system. The voice recognition system captures spoken commands, processes them through natural language interpretation, and translates them into system actions, serving as a mediator that reduces direct manual control requirements.
2Productivity
If voice recognition systems are implemented to reduce workload, then user input steps are reduced, but recognition accuracy becomes insufficient for reliable use
Solution Approach 1:
The patent merges eye tracking and voice recognition systems into an integrated input interface. The eye tracking system identifies which display item the user is interested in, while the voice recognition system processes spoken commands. Together, they provide both speed (through voice) and accuracy (through gaze confirmation), resolving the accuracy-speed tradeoff.
3Reliability
If multiple input methods are integrated to improve accuracy, then system reliability increases, but device complexity increases
Solution Approach 1:
The patent creates a universal input system that handles multiple input modalities (eye gaze, voice commands, traditional controls) through a single integrated processor. This multi-functional approach allows the system to adapt to different input preferences and conditions without requiring separate dedicated systems for each input method.

AI summary
The present disclosure is directed to a method for managing a user interface. The method may include the step of detecting a gaze of a user within a display. The method also includes the step of correlating the gaze of the user to an item displayed on the display. A further step of the method entails receiving an input from the user related to the item.
