Gaze Detection with Secondary Input for Gaming Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic gaming machines face challenges in providing an immersive experience due to the burden on hardware from increasing complex and visually stimulating content, and gaze detection systems struggle with accuracy and accidental inputs.
Innovation Solution
The implementation of gaze direction data combined with secondary inputs such as touch, voice, gesture, and mobile device data to accurately determine player interactions and control game operations, allowing for dynamic updates of the game environment based on player eye gaze and other inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gaze detection is used to control EGM inputs, then player interaction intuitiveness is improved, but input accuracy deteriorates due to accidental selections
Solution Approach 1:
The patent introduces a secondary input device (touchscreen, button, or gesture sensor) as an intermediary between the player's intent and the game system. The gaze detection identifies the target element, but the secondary input provides explicit confirmation, acting as a mediator that eliminates accidental selections while preserving intuitive interaction.
Solution Approach 2:
The system uses the player's own secondary input actions to validate and confirm gaze-based selections. The player naturally touches, presses, or gestures toward the element they are already looking at, providing self-confirmation without requiring separate manual navigation through menus or buttons.
2Adaptability or versatility
If hardware resources are increased to support complex visual content, then gaming experience quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex hardware processing with lightweight computational methods. Instead of relying on powerful graphics processors to create immersive experiences, the system uses simple gaze direction calculations and basic coordinate transformations that can be performed by standard microprocessors, significantly reducing hardware requirements.
3Measurement precision
If multiple input methods are integrated for validation, then input accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal secondary input interface that can function in multiple modes (touchscreen, physical button, or gesture recognition) depending on the specific EGM configuration. This multi-functional approach allows the same basic validation mechanism to work across different device types without requiring separate specialized components for each input method.

AI summary
Methods of operating an electronic gaming machine are provided. Methods include operating a wagering game on the electronic gaming machine by displaying a game window associated with the wagering game on an electronic display screen of the electronic gaming machine, receiving, using at least one data capture camera device, gaze direction data corresponding to a player, receiving a secondary input from the player, the secondary input being received, evaluating the gaze direction data of the player and the secondary input, performing, by the electronic gaming machine, at least one operation or modification responsive to evaluating gaze direction data and the secondary input.
