User Adaptation System for Video Game Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videogames often pose difficulty challenges that can be inaccessible to players with limited dexterity or coordination due to conditions like RSI, arthritis, or Parkinson's disease, as they require specific controller inputs that may be difficult for these users to perform, leading to frustration and inability to progress in the game.
Innovation Solution
A system and method that evaluates a user's physical input capabilities through a calibration test, modeling their dexterity relative to a notional standard user, allowing for adjustments in game difficulty and providing mitigating features such as control remapping, auto-inputs, or damage reduction to facilitate gameplay for users with limited capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the game requires specific controller inputs to be performed rapidly or with complex sequences, then the game challenge and entertainment value are improved, but the accessibility for players with limited dexterity or coordination deteriorates
Solution Approach 1:
The system dynamically adjusts game parameters based on real-time analysis of player performance data. When a player struggles with specific input sequences or reaction time requirements, the system automatically modifies game difficulty, such as extending time limits, reducing enemy aggression, or providing additional hints, thereby maintaining accessibility while preserving challenge for capable players
Solution Approach 2:
The system changes multiple game parameters simultaneously based on player capability assessment. This includes adjusting difficulty levels, modifying control sensitivity, changing enemy behavior patterns, and adapting puzzle complexity to match the player's demonstrated dexterity and coordination levels, ensuring the game remains challenging yet accessible
2Productivity
If the game difficulty is increased to provide greater challenge, then the entertainment value for skilled players is improved, but the frustration and inability to progress increases for players with limited capabilities
Solution Approach 1:
The system continuously monitors player performance metrics such as completion times, error rates, and input accuracy. Based on this feedback, it automatically adjusts game difficulty to maintain an optimal challenge level. When players struggle, the system provides constructive feedback through hints or automated assistance, ensuring they can progress without excessive frustration while still experiencing challenge
Solution Approach 2:
The system performs preliminary analysis of player capabilities through calibration tests or early-game performance tracking before fully engaging the player in challenging content. This allows the system to pre-adjust difficulty settings and prepare appropriate assistance mechanisms to ensure players can progress reliably while maintaining entertainment value
3Ease of operation
If traditional difficulty adjustment options are provided (such as hint systems or reduced enemy health), then some accessibility issues are addressed, but the solution is insufficient for players with significant physical limitations
Solution Approach 1:
The system implements a universal adaptation framework that provides multiple types of assistance simultaneously - including control remapping, automated input assistance, extended time limits, and dynamic difficulty adjustment - making it suitable for various types of physical limitations. This multi-functional approach ensures comprehensive accommodation for players with different kinds of disabilities beyond what traditional single-purpose difficulty settings can provide

AI summary
A method of evaluating a videogame for a first user comprises the steps of performing a calibration test using a physical input device to evaluate at least a first physical input capability of the first user with respect to that physical input device; evaluating at the at least first physical input capability exhibited with respect to that physical input device during reference play of the videogame by one or reference users other than the first user; comparing the at least first physical input capability exhibited during reference play with that of the first user; and providing an evaluation of the videogame's suitability for play by the first user, based upon the comparison.
