Innovation Solution
An electronic gaming machine equipped with a card reader, data storage, graphics processor, display device, data capture camera, and game controller that uses eye gaze data to dynamically update the game environment, allowing players to interact with invisible game components using x-ray vision effects, thereby increasing engagement and interaction possibilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of physical buttons and game components is increased, then user interaction capabilities are improved, but the device size and hardware complexity increase
Solution Approach 1:
The patent replaces physical buttons and mechanical interaction components with an eye-tracking camera system and software-based game components. The camera captures eye gaze data to determine player selection, eliminating the need for physical buttons while maintaining interaction capabilities. This substitution reduces hardware complexity while preserving adaptability.
Solution Approach 2:
The patent uses visual representations (display screens) to create copies of game components that can be manipulated through eye gaze rather than physical contact. The display shows virtual buttons and game elements that replicate the functionality of physical components without requiring physical hardware, thereby reducing device complexity while maintaining versatility.
2Adaptability or versatility
If the number of physical buttons and game components is increased, then user interaction capabilities are improved, but the physical space required increases
Solution Approach 1:
The patent transitions from two-dimensional physical buttons on a panel to a multi-dimensional virtual interface displayed on a screen. The eye-tracking system adds another dimension by capturing spatial eye position data to map onto the display, allowing numerous game components to be arranged in a virtual space that exceeds physical constraints while maintaining compact hardware footprint.
Solution Approach 2:
The display screen serves multiple functions: it displays game components, provides visual feedback for eye gaze detection, and acts as the interaction interface itself. This multi-functionality eliminates the need for separate physical buttons and components, reducing physical space requirements while maintaining comprehensive interaction capabilities.
3Measurement precision
If eye gaze tracking is implemented, then interaction precision is improved, but measurement and detection difficulty increases
Solution Approach 1:
The patent introduces calibration patterns as an intermediary element between the eye-tracking camera and the final gaze measurement. These patterns provide reference points that facilitate accurate mapping of eye position to display coordinates, improving measurement precision while simplifying the detection process through systematic calibration procedures.

AI summary
An electronic gaming machine to play an interactive game where a players eye gaze acts as x-ray vision. A graphics processor generates an interactive game environment and defines a viewing area as its subset. A display device displays the viewing area, where a visible game component masks an invisible game component. A display controller controls rendering of the viewing area on the display device using the graphics processor. At least one data capture camera device continuously monitors player eye gaze to collect player eye gaze data. A game controller calculates a player eye gaze location relative to the viewing area, the location corresponding to the invisible game component, and triggers a control command to the display controller. In response, the display controller controls the display device in real-time to provide a graphical animation effect representative of a visual update to the visible game component to reveal the invisible game component.
